JavascriptUtil
public class JavascriptUtil (Code)
Various Javascript code utilities. The escape classes were taken from jakarta-commons-lang which in turn borrowed from Turbine and other projects. The list of authors below is almost certainly far too long, but I'm not sure who really wrote these methods.

Method Detail
escapeJavaScript
public static String escapeJavaScript(String str)(Code)

Escapes the characters in a String using JavaScript String rules.

Escapes any values it finds into their JavaScript String form. Deals correctly with quotes and control-chars (tab, backslash, cr, ff, etc.)

So a tab becomes the characters '\\' and 't'.

The only difference between Java strings and JavaScript strings is that in JavaScript, a single quote must be escaped.

Example:

 input string: He didn't say, "Stop!"
 output string: He didn\'t say, \"Stop!\"
 


Parameters:
  str - String to escape values in, may be null String with escaped values, null if null string input



isReservedWord
public static boolean isReservedWord(String name)(Code)
Check to see if the given word is reserved or a bad idea in any known version of JavaScript.
Parameters:
  name - The word to check false if the word is not reserved



unescapeJavaScript
public static String unescapeJavaScript(String str)(Code)

Unescapes any JavaScript literals found in the String.

For example, it will turn a sequence of '\' and 'n' into a newline character, unless the '\' is preceded by another '\'.


Parameters:
  str - the String to unescape, may be null A new unescaped String, null if null string input
