java.lang.Objectcom.ibm.as400.util.html.HTMLTransform
public class HTMLTransform extends Object
The HTMLTransform class encodes and decodes a string's tags for use in an HTMLTagElement's control name, initial value, or displayed text. There are a set of special characters reserved for creating HTML tags. Those special characters have a corresponding set of replacement characters that allow users to visually see those characters in a browser.
For example, if you wanted to set the value attribute of a TextFormInput object to a resource link so you could see the HTML link in the text input box, the HTML link tag would need to be encoded to see the special characters(<, >, and "):
<input type="text" name="myText" value="<a href="http://www.myLink.com/">Link</a>" />
The following example uses the HTMLEncoder class to encode and decode the value of a TextFormInput so it displays properly:
// The string to use for the TextFormInput value attribute.
String s = new String("<a href="http://www.myLink.com/">Link</a>");
// Encode the string.
String e = HTMLTransform.encode(s);
// Create the TextFormInput object.
TextFormInput input = new TextFormInput("myText", e);
// Set the input size so the entire value can be seen.
input.setSize(45);
System.out.println("TAG: " + input.getTag() + "\n");
// Output the string with the special characters encoded for display in a browser.
System.out.println("Encoded: " + e + "\n");
// Output the string with the specials characters decoded back to the original string.
System.out.println("Decoded: " + HTMLTransform.decode(e));
Here is what will be produced:
// The TextFormInput with an encoded string. <input type="text" name="myText" value="<a href="http://www.myLink.com/">Link</a>" size="45" /> // The encoded string. <a href="http://www.myLink.com/">Link</a> // The decode string. <a href="http://www.myLink.com/">Link</a>
Here is what the browser will show:
