HOME > JavaScript Tricks

Each link will demonstrate the JavaScript in action.


Send PopUp Window to Back
When a visitor comes to your web page, it automatically loads a second window behind the top one.

<!-- STEP ONE: Paste this code into the HEAD of your HTML document --> <script language="JavaScript"><!-- browserVer=parseInt(navigator.appVersion); HB=window.open('http://www.your-domain.net/background-window.html','HBback'); if(browserVer>=4){ window.focus(); }// --></script> <!-- STEP TWO: Change the URL in the script to reflect your own web page you wish to pop up in the background -->

PopUp Window When Link is Clicked
Window pops up when a text link or graphic is selected. Keeps visitors in front of your 'main' page while allowing visitors to visitother places on the web.

<!-- TWO STEPS TO INSTALL: 1. Copy the code into the HEAD of your HTML document. 2. Add the last code into the BODY of your HTML document and change web address. --> <!-- STEP ONE: Paste this code into the HEAD of your HTML document --> <SCRIPT LANGUAGE="JavaScript"><!-- Begin function popUp(URL) {day = new Date();id = day.getTime();eval("page" + id + " = window.open(URL, '" + id + "', 'toolbar=0,scrollbars=1,location=0,statusbar=0,menubar=0,resizable=1,width=450,height=450,left = 175,top = 50');");}// End --></script> <!-- STEP TWO: Copy this code into the BODY of your HTML document --> <A HREF="javascript:popUp('http://your-domain.net/popup.html')">Tell A Friend</A>

PopUp When Leaving Site
A powerful method of getting subscriptions to your email newsletter when visitors exit a site.

<script LANGUAGE="JavaScript"><!-- Begin var expDays = 1; // number of days the cookie should last var page = "http://www.your-domain.net/exit-pop.html"; var windowprops = "width=280,height=300,location=no,toolbar=no,menubar=no,scrollbars=no,resizable=no"; function GetCookie (name) { var arg = name + "="; var alen = arg.length; var clen = document.cookie.length;var i = 0; while (i < clen) { var j = i + alen; if (document.cookie.substring(i, j) == arg) return getCookieVal (j); i = document.cookie.indexOf(" ", i) + 1; if(i == 0) break; } return null; } function SetCookie (name, value) { var argv = SetCookie.arguments; var argc = SetCookie.arguments.length; var expires = (argc > 2) ? argv[2]: null; var path = (argc > 3) ? argv[3] : null; var domain = (argc > 4) ? argv[4] : null; var secure=(argc > 5) ? argv[5] : false; document.cookie = name + "=" + escape (value) + ((expires == null) ? "" : ("; expires=" + expires.toGMTString())) + ((path == null) ? "" : ("; path=" + path)) + ((domain == null) ? "" : ("; domain=" + domain)) + ((secure == true) ? "; secure" : ""); } function DeleteCookie (name) { var exp = new Date(); exp.setTime (exp.getTime() - 1); var cval = GetCookie (name); document.cookie = name + "=" + cval + "; expires=" + exp.toGMTString(); } var exp = new Date(); exp.setTime(exp.getTime() + (expDays*24*60*60*1000)); function amt(){ var count = GetCookie('count') if(count == null) { SetCookie('count','1') return 1 } else { var newcount = parseInt(count) + 1; DeleteCookie('count') SetCookie('count',newcount,exp) return count } } function getCookieVal(offset) { var endstr = document.cookie.indexOf (";", offset); if (endstr == -1) endstr = document.cookie.length; return unescape(document.cookie.substring(offset, endstr)); } function checkCount() { var count = GetCookie('count'); if (count == null) { count=1; SetCookie('count', count, exp); window.open(page, "", windowprops); } else { count++; SetCookie('count', count, exp); } } // End --></script>

 

Other Great JavaScripts You Can Use

Pop-Up Window Maker
Fill out the specifications of the popup window you would like to use, including the URL and the various options such as menubars, toolbars, scrollbars, etc, and click the generate button. Just add this generated code to your site, or even have us mail it to you! Neat!


Bookmark Us
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)


Frameless PopUp
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.
