    | 404 Referrer | Do you get lots of 404 "file not found" errors every time you
    change a file's name? Use this simple script to include in a HTML form (a hidden field)
    that contains the referring page's address. | 
  
    | Arrow Links | This neat little JavaScript will indicate which link is selected with a
    little arrow image. Hard to explain, but you'll understand when you see it! | 
  
    | Bookmark Us | (Internet Explorer Only) Allow your visitors to click one text link to
    quickly and easily add your site to their "Favorites." Don't let your visitors
    lose you because they forget to bookmark your site! (Netscape Users won't get any errors,
    but instead of the bookmark link, see a message reminding them to bookmark the site) | 
  
    | Born On Date | In place of the boring "Last Updated" script, you can use this
    script. It does everything and more - it gives the page title, the day the page was last
    updated, and if the page has been updated since the visitor's last visit all in a cool
    little table! | 
  
    | Break Frames | If a visitor comes to your site and is looking through frames, this
    script will automatically make the page break out of frames. As an added bonus, it's only
    8 lines of script! | 
  
    | Check Url | This script is particularly useful for those who have their site on a
    free webspace provider, then use a "come.to" redirecting service. What this
    script will do is analyze the URL the visitor is at, and if they did not came to your site
    via the redirecting URL, it can print out a message telling them that is your new URL. | 
  
    | Close
    Window | JavaScript can close a window when you push a button or click a text
    link. Super-short script too! | 
  
    | Closing Windows | This set of short, easy scripts shows six different ways to close a
    window from JavaScript, including closing windows from a clicked link, a clicked image, or
    a clicked form button. Close framed pages also! | 
  
    | Color Chart | JavaScript can print out 8 tables with the 512 standard colors and their
    corresponding #RRGGBB values. | 
  
    | Content
    Protector | If your content page is loaded directly (not in frames) the page is
    reloaded in your frames. And to the aid of webmasters everywhere, this script also foils
    other sites loading your content page in their frames. Visitors are notified of the
    bandwidth theft then are sent to the page on your site (if used with our Dynamic Frameset
    script) or back to your main page. | 
  
    | Crazy
    Window | Your browser has gone crazy! The browser window jumps to random positions
    around the screen at a dizzying rate of 10 times a second. It is a good idea to load any
    page that uses this script in a new browser window so your visitor still can access your
    site. | 
  
    | Date Time
    Stamp | With this script, you can have the date and time the page was loaded
    stamped to the page. This would make a wonderful header or footer for any web page. | 
  
    | Date Updated | On your site, you might want to just let visitors know the date that the
    script was updated, but not the time (maybe it's not important?) This simple script (about
    a dozen lines) you can do just that! | 
  
    | Delayed Gif | Normally, animated GIF images start as soon as they are loaded on the
    page. But, if your GIF only loops once, it displays before the rest page is completely
    visible. This JavaScript solution ensures that the page is fully loaded before the
    animated GIF begins. | 
  
    | Determined
    Popup | This short, easy script set launches a window that continually re-opens
    itself and cannot be permanently closed unless the visitor clicks on a link that you
    provide. Compatible Browsers: NS6 and IE4-6. | 
  
    | Dom Browser | The DOM Browser is a visual, interactive representation of the DOM
    (Document Object Model). It's helpful to beginners learning to interact with the DOM in
    JavaScript. It's also a great tool for side-by-side comparisons of Netscape, Internet
    Explorer, and other browsers and how they interpret the document and its elements. | 
  
    | Drag N Drop | Simply click images on the web page, drag to move, and then drop images
    anywhere on the web page. A fun way to allow your visitors to interact with your site. | 
  
    | Dynamic Title Bar | Displays changing text in a multi-message display in the browser title
    bar. Any number of message lines may be used, and a moving, attention-getting slide box
    draws the eye to the messages. | 
  
    | Dynamic
    Sized Image | Sometimes, your image does not look very good in different sized browser
    windows. This script will proportionally resize a graphic to fit within the current window
    or frame when a page is loaded, thus giving a more consistent and attractive look to your
    page. | 
  
    | Email
    This Page | Allow your visitors to email the current page to a friend. They just
    enter a friend's name and email address. It will send them a link to the current web page
    address in an email message signed by you, courtesy of freedback.com. | 
  
    | Email
    Protector | Here's a clever way to prevent email address collecting robots from
    grabbing your email address while still making your address available to your visitors. | 
  
    | Fake Counter | If you don't quite have the traffic you'd like to your site, you can use
    your own fake page counter! | 
  
    | Floating
    Link | This link will float in the upper right corner of the browser window and
    return you to the top of the window when clicked. Easily modified to include floating text
    or image! | 
  
    | Focus Onload | You can easily put the user's cursor inside a text box (calling giving
    the text box focus) as soon as the page is loaded. This helps ensure that visitors do not
    overlook an important form item on your site. Only 1 line of code! | 
  
    | Frameless
    Popup | (IE4+) Launches a popup window without the Windows frame or titlebar. In
    other browsers, it launches a standard popup window. Position, width, and height are
    settable. Automatic closing of the window on leaving the page may also be optionally set. | 
  
    | Go Behind
    Popup | Launches a frameless "go-behind" popup banner window that
    cannot be closed unless the banner ad is clicked on. The frameless banner window persists,
    even if the launching browser window is closed. The banner window closes once the banner
    is clicked. | 
  
    | Highlighted
    Text | Captures any text that has been highlighted with the cursor. In Internet
    Explorer, it even grabs text highlighted within a text box or textarea. | 
  
    | Image
    Manipulator | Displays an online image or local image from your computer under various
    width and height manipulations that you enter. Useful for determining the best size for an
    image on your site without all the work. | 
  
    | Image
    Sized Window | Sizes a new popup window to the exact dimensions of the image in that
    window. | 
  
    | Image Load | Notifies the user is an image on your site fails to load properly or if
    it is aborted when loading. Definitely an excellent example of the onAbort and onError
    image event handlers in use. Please note that in the script example we intentionally
    included a broken image that fails to load properly to display the script in use. | 
  
    | Last
    Modified | When you just can't stand to look at another "Last Updated: Feb 02
    1998 14:12:56:10" Script, give this script a try. It'll write to the page in the
    format, "Last Updated February 2 1998" | 
  
    | Launch Date | Displays one of two messages after comparing the current date on the
    user's computer to a date that you determine, such as a product or web site launch date. A
    before or after message can be customized with your own HTML code, including images. | 
  
    | Link Of
    Minute | JavaScript will create a link that will change depending on the minute of
    the hour! You can add as many entries as you want! | 
  
    | Load HTML | This script loads an external html file into a css layer. It is NS6
    compatible as well as supporting IE4+ and NS4. | 
  
    | Logo Branding | Have you seen the floating logo on Geocities sites? How would you like to
    have your own logo floating in the corner of your site? This script does just that! | 
  
    | Menu
    Branding | Keeps logo (or text) in the bottom right corner of the browser window as
    they scroll the page up and down. The logo glides very smoothly when the page is scrolled
    and looks great. When their cursor is on the logo, a menu appears in its place offering
    links to different sections of the site. The menu returns to the logo a few seconds after
    the move the cursor off the menu. | 
  
    | Mouse
    Coordinates | Capture mouse X - Y positions with this easy script. Works much like our
    Mouse Tracker script, but much simpler! Compatible in Internet Explorer and Netscape
    versions 4+. | 
  
    | Mouse
    Coordinates 2 | This script can display the mouse's X and Y coordinates in the status
    window. | 
  
    | Mouse Orbit | A series of dots orbit the mouse cursor on the page, giving the
    appearance of a comet effect. | 
  
    | Mouse
    Bubbles | Bubbles float up from mouse giving the effect that the mouse is under
    water. The bubbles even expand in Internet Explorer. | 
  
    | Move
    Window | Move the browser window by simply clicking the buttons on the page. | 
  
    | Move Window 2 | Move the browser window simply by using the arrow keys! IE only (Frames
    not supported) | 
  
    | Netscape
    Source Image | When visitors using Netscape right-click your web page and select
    "View Source" or go to the View menu bar and select "View -> Page
    Source" the entire source code of your page is displayed. Interestingly enough, it's
    possible to actually insert an image into Netscape's view source page instead of just
    having text. When Netscape users view the source of your page, they see an image as well
    as the source code! Your image could tell the visitor that they are not allowed to view
    this source code, for example. | 
  
    | New Links | Displaying links as new for a few weeks after adding them is great. But,
    adding, removing, and updating that "New" icon for each link is pointless! Let
    JavaScript do your work for you! Just add a small code (less than 40 characters) next to
    each link with the date you want it to expire, and it will automatically display the
    "New" icon until the expiration date. | 
  
    | No Right
    Click | (4.0+ browsers) Ever wanted to prevent users from borrowing images from
    your site through right-clicking them and "save image as..." or right-clicking
    the page and viewing your page source? This script will (attempt to) disable the right
    click on your page! As explained, however, this script is not fool-proof !! | 
  
    | Page
    Extension | Displays a message based on the extension (like .html) of the web page.
    And, it's a breeze to add more file types to the script. | 
  
    | Page
    Scroller | Placing the cursor on the page's up or down arrows located in the bottom
    right corner of the browser window will automatically scrolls the page. | 
  
    | Page Time | This script will count the number of seconds a person has been on your
    webpage. | 
  
    | Page Up For | JavaScript can even display how long your web page has been online. Just
    enter the date, the script does the calculations, and prints out the time. | 
  
    | Page
    Variable | Not exactly the most used script, but this one allows you to reference
    the page name in a variable. Instead of yourdomain.com/index.html, you can use this script
    to create a variable that stores index.html for your use! You can use it with alerts,
    document.write, etc. | 
  
    | Page Viewed
    Date | This JavaScript will write out when the page was viewed, according to the
    visitor's clock. | 
  
    | Preload Page | Displays a loading message as the page, including images and sound
    elements, are loaded in the background. When the page finishes loading the screen is
    shown, similar to how Macromedia's Flash plugin works | 
  
    | Reload On Resize | Useful for situations when a page resize moves the page elements
    improperly or causes JavaScript errors, which has been known to occasionally occur on
    pages with layers. As a solution, this script reloads the web page when the user resizes
    the page. | 
  
    | Resize
    Link | Useful for webmasters, this script lets you view any web page at
    different resolutions by simply clicking the link and entering the height and width
    values. Tip: You can drag the link to your Links toolbar, and use it on any page you are
    viewing. | 
  
    | Resolutions Test | Shows how a page will look at different screen resolutions. It includes
    the 3 most common resolutions as well as inputs for custom window sizes. It even gives you
    the exact inner document dimensions for precision testing! | 
  
    | Right
    Click Menu | (Internet Explorer Only) Displays a menu when the visitor right click's
    on the page. You can easily use style sheets to modify the menu skins, or write your own. | 
  
    | Roman
    Numerals | This script helps you write the copyright statements on your page. It
    outputs the correct Roman Numerals for any year you want, including the current year. | 
  
    | Scrollbar
    Color | (IE 5.5+) Changes the color of the scrollbars in a page dynamically. | 
  
    | Set
    Homepage Link | Allow the visitor to set your site as their homepage with a link. This
    script works best in Internet Explorer, but also displays the appropriate information
    based on browser type. | 
  
    | Smart Popup | Create popup windows that will center on your screen or popup near your
    link without popping off the edge of the screen. Also shows how to create a clickable
    popup or a popup that displays when you hover over the link with your mouse. | 
  
    | Source
    Viewer | View the source of any web page. This will bypass any "No right
    click" scripts on the page. | 
  
    | Thumbnail
    Viewer | Save page space by opening a new window to display larger images on your
    site when a thumbnail image or a picture text link is clicked. The same window is re-used
    when the images are the same size. | 
  
    | Time Box | This is a neat little script that makes your web page look a whole lot
    more professional. This JavaScript will display a small box with the time the visitor
    loaded the page. | 
  
    | Time
    Greeting | Don't just welcome your visitors anymore, JavaScript can write good
    morning, good evening, or good afternoon based on the time the page was loaded, according
    to the user's system clock. | 
  
    | Title Bar Typist | This script types a string or series of strings into the Title Bar. | 
  
    | Top Alert | If you want to show your visitors how long they have been on your page
    but don't exactly like those clock displays, then you might like this script. When the
    visitor leaves or clicks the button, they are alerted to the time they have been on your
    page. Many times, they won't even expect it! | 
  
    | Top Clock | Occasionally, it might be interesting to show the visitor how long they
    have been on your page. So, you can use this script to write a clock to the screen that
    will tell them exactly that! | 
  
    | Top Onunload | When someone visits your web page, JavaScript will start the clock. When
    the leave that page, they will be alerted with the time they have been viewing the page! | 
  
    | Top Seconds | If the other time on page scripts seem too impersonal for you, this could
    be your solution. Instead of the 00:00 readout, it displays 'X Secs'. | 
  
    | Web Cam Time | Set your Web Cam for a Online viewing time and an Offline viewing time.
    This is very useful if you do not have you cam online 24/7. It will display the updated
    web cam image while during the online time, and an offline image during you offline time. | 
  
    | Week Day
    Image | Displays a new image every day of the week. For example, it displays
    monday.jpg on Monday, tuesday.jpg on Tuesday, etc. You can also change what image is shown
    each day. | 
  
    | Window Print | Quickly and easily print the current page by clicking on a link. Add this
    function to a submit button to automatically print a submitted form! |
