does anyone know how to check for \ in a text box substr does not work 1

[bankofalltrades]

I'm trying to have a text box that the user will copy/paste a file destination into. I'm validating that the user pasted correctly and that the beginning of the string starts with \\ any ideas?

you can use the match method.

var myval = document.getElementById('myid').value;
if(myval.match("\") == "\"){
   do whatever;
}

if you want to check if something is NOT in the string you can use...

var myval = document.getElementById('myid').value;
if(myval.match("\") == null){
   do whatever;
}

hope it helps.

sorry you need to use two slashes ("\\") , i only showed one as that's what your thread heading showed - lol

thinking about it you might have to escape them!

so

if(myval.substring(0,2) == "\\\\"){do whatever;}

could do it.
