@007JulienJul 10.2012 — An essay of search for one of these characters in strings...
[CODE]
[COLOR="Blue"]
// Multiple strings to split for tests[/COLOR]
var str="hello word !@<script>@How are you ?@Well 5/5 !@2*2 = 4@..."...@..|..@Good luck !".split('@');

[COLOR="Blue"]// The test for one of the following characters: /:*?"<>|
[/COLOR]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 !');[/CODE]All this characters (except colon, less and more) must be escaped with a backslash in the character class delimiter by the two square brakets...

if (InPut.match(/^.*?[\/:*?"&lt;&gt;|].*?$/)) {
alert('Found one.');
} else {

[/QUOTE]

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.
