[RESOLVED] Vaildation of Characters

Can Any One Tell Me A If Statement That Will Check For These Characters

\/:*?"<>|

Thank You

An essay of search for one of these characters in strings...

// Multiple strings to split for tests
var str="hello word !@<script>@How are you ?@Well 5/5 !@2*2 = 4@...\"...@..|..@Good luck !".split('@');

// The test for one of the following characters:  \/:*?"<>|
for (var l=str.length,i=0;i<l;i++) 
	alert(str[i]+(/[\\\/:\*\?\"<>]/.test(str[i])?' contains':' does not contain ')+' one of the indicated (\/:*?"<>|) characters !');

All this characters (except colon, less and more) must be escaped with a backslash in the character class delimiter by the two square brakets...

InPut=prompt('What?','');
if (InPut.match(/^.*?[\\\/\:\*\?\"\<\>\|].*?$/)) {
 alert('Found one.');
} else {
 alert('None found.');
}

The caret (^) at the beginning forces the pattern to start at the beginning of the string.
The dollar sign ($) at the end forces the pattern to go all the way to the end of the string.
The dot-star-question-mark (.*?) sets allow us to ignore leading and trailing characters.
The square brackets ([]) surround multiple individual characters to seek.
Each of the individual characters is preceeded by a back-slash (\) so that it doesn't have any special meaning.
