For the original code and script for this particular script see Expand-Collapse Paragraph. In general, there are two types: JavaScript was initially called LiveScript at Netscape while it was under development.

The javascript file is expandcollapse. A quantifier is a single character that immediately follows the specified item it applies to, to restrict the number of successive occurrences of these items at the specified position in the content of the element; it may be either: These requirements only apply to the HTML syntax.

Element declarations name the allowable set of elements within the document, and specify whether and how declared elements and runs of character data may be contained within each element. ECMA version 1 compliance 1. A common use is to have a name more recognizable than a numeric character reference for an unfamiliar character.

My page looks good on one browser, but not on another. When the user clicks on such a link, the specified JavaScript code is executed. They may claim to support a specific version, but will have vastly different capabilities. One important way to use this syntax is to type it directly into the Location field of your browser, where you can test arbitrary JavaScript code without having to open your editor and create an HTML file containing the code.Javascript Combo.
