  1. Using the Select Box as a Navigation Tool

    If we want the select box to function as a genuine menu, then a click on a given option (of the select box) must give us the same range of possibilities as does a click on the items of a normal menu. So a click should allow us to go to a new page, to open a popup window, to produce an alert etc.

    We can achieve this with the help of a function that has the following general form:
    Code:
    var which="";
    function DoSomethingWithOptionvalue(which) {
    var optionValue = document.getElementById(which).options[document.getElementById(which).selectedIndex].value;

  2. All Levels Menu- top headers revealed onClick instead of onMouseover

    Original Script: All Levels Navigational Menu v2.2

    Changes: This modified version of ddlevelsmenu.js causes the top level sub menus to be revealed onClick of the primary headers (instead of the default onMouseover). The remaining sub levels are still revealed onMouseover like before.

  3. Compact Cookie Unit

    Cookies are often confusing. Much of the confusion can be eliminated if you know that all cookies are strings. If you want to store an array, function, number, or an object in a cookie, you must convert it to a string before storage and upon retrieval change it back into the object/array/function/number that it was. Cookies are therefore best used for string storage and retrieval. This unit doesn't pretend to eliminate all of the possible confusions that can arise from "when and where in ...

  4. Dynamically minimizing a DHTML Window

    Original Script: DHTML Window

    By default the DHTML Window script can only be minimized by clicking on the "minimize" icon located on the upper right of the opened window. Someone asked on the forums if there's a way to do this dynamically, such as via a link instead. Well, certainly. Given the below example DHTML Window:

    Code:
    var googlewin=dhtmlwindow.open("googlebox", "iframe", "http://images.google.com/", "#1: Google Web site",

  5. "Operation Aborted" error in IE when inserting new elements into the DOM, and fix

    The DOM lets you dynamically create and add elements to the page, such as the following, which creates an image on the fly and adds it to the end of the document:

    Code:
    var img=document.createElement("img")
    img.setAttribute('src', 'dd.gif')
    document.body.appendChild(img)
    Ideally such an operation should be done after the document has loaded, though in most browsers, I noticed you can get away with it. In IE6 and IE7, however, things get a lot more ...
