For JavaScript in the <script> block or JavaScript included with a src attribute: nothing more is needed than escaping the single quote or double quote - depending on how the JavaScript string is quoted. Example: var a = 'My name is <?php echo str_replace('\'', '... For inline JavaScript, escape HTML special characters : <?php echo '<a href="test" onclick="alert(\...

If you are looking for a solution for a progress bar, I direct you to the following resources: Bare Naked App provides a simple and elegant solution based on pure CSS with two images. You control the percentage of completion through the background-position attribute of the CSS. HTML: <img src="/images/percentImage.png" alt="... CSS: img.percentImage { background: white url(/imag... Images: (percentImage.png) (percentImage_back.png) WebAppers extended the above solution with JavaScript. They also added several colored images: JQuery UI has a built-in progress bar widget. However, if you want to get to understand some of the foobar needed to get CSS to work (in general) through this example, stay with me for the rest of this note. Initially I was thinking, a progress bar should be easy: just make...

In the following HTML code, I attached an inline handler to the text field input and added two event handlers with addEventListener / attachEvent . Both IE and Firefox called the inline handler first. But the order in which the added event handlers were called are different between IE and Firefox (IE calls attached_click2 first). Further, if I add the same event handler multiple times, IE calls the handler the same number of times. But Firefox only calls the same handler once, no matter how many times it was added. <html> <body> <form> Input: <input type="... You can attach an event handler to an HTML element either inline , with JavaScript , or by calling addEventListener (DOM level 2), or attachEvent (IE specific). When you...

In this note I'll show you how to create and package a JSP custom tag. The purpose of this tag is to display a random splash image for a home page, among a set of images. We should be able to add or delete candidate splash images from the WAR archive without the need to change the JSP. This is the intended use of the tag: <%@ taglib uri="http://custom.tag.com/demo" prefix... In the above example you provide a set of images named splash*.png (e.g., splash1.png, spalsh2.png, ...), and the tag will pick a random one to display when the JSP is rendered. Let's get started. I'll use Maven for this purpose. Create the standard Maven directory structure ./pom.xml ./src ./src/main ./src/main/jav... pom.xml <project xmlns="http://maven.apache.org/POM/4.0.0"... SplashTag.java package tagdemo; import java.util.ArrayList......

Some interesting information about getting the value of tabindex with JavaScript: http://www.fluidproject.org/pipermail/fluid-work/2007-December/001129.html Especially, IE returns 0 when tabindex is not set, making it indistinguishable from where tabindex is set to 0.

You can use applet , object , or embed tags to embed an applet in your HTML page. However, The applet tag is interpreted by both IE and Mozilla family of browsers. The applet tag won't automatically download a JRE if the Java Plug-in isn't already installed. The object tag works only for IE The embed tag works only for Mozilla family of browsers, i.e., Firefox. Use applet tag: <applet code="MyApplet.class" width="200" ... Use object tag: <!-- latest JRE --> <OBJECT classid="clsid:... Use embed tag: <!-- highest JRE that supports MIME type ... Mixed object and embed tag: <object classid="clsid:8AD9C840-044E-11D1-B3E9... You need to use a different name for the Mozilla embed tag and use that name to refer to the applet...

The scriptable attribute defaults to false . However, even when you set it to true , there is a time delay between when the applet is loaded and when it becomes scriptable . The following code may fail: <html><body> <object classid="clsid:8AD9C840-04... You need to wrap the JavaScript like this: <script language="JavaScript" type="text/javascrip...

IE and firefox both support client side XSLT. This can be done by inserting an xml-stylesheet into the XML file, which would trigger the browser to apply the XSL to the XML document and generate a transformed page: <?xml version="1.0" encoding="utf-8" ?> <?... Or, it can be done more dynamically with client side JavaScript. However, IE and FF offer different APIs for XSLT. Below is my attempt to bridge the differences. It's been tested to work for IE 7.0, FF 2.0 and Opera 9.0.2. function XSLT(url) { var xslt = false; ... The following HTML page shows how to use it: <HTML> <HEAD> <SCRIPT language="JavaS...
