webMathematica User Guide 307When the form is activated by the submit input tag, the browser makes a request to the URLreferred to by the action attribute. It sends the name and value pairs from all of the inputtags in the form. This is the most basic way to activate HTML.One thing to remember about form elements is that the name/value pairs can bespecified in the URL. You may have seen them in something like http://myserver/document?ARG1=10&ARG2=20.JavaScriptJavaScript is a compact object-based scripting language for developing client and server internetapplications. JavaScript code can be embedded directly in an HTML page. It can, for example,embellish the operation of form and input elements. One problem with JavaScript is that itis not uniform across different browsers. JavaScript can manipulate the browser and the documentsthat the browser holds. It can also interact with applets and plug-ins.Some of the examples included with webMathematica work with JavaScript.AppletsApplets are programs written in Java that can run in a Java-enabled browser. They are lesstightly integrated with HTML than JavaScript but are probably easier to develop and can call onmuch of Java technology. As with JavaScript, some (especially older) browsers give incompleteand poor support for applets. Applets can call on the large collection of functions that are availablein the Java programming language and can actually draw into the browser.Some of the examples are designed to work with applets.
