banning certain characcter from javascript validation

[karen987]

This is a javascript validation funcction.

i want to add a statement that bans the " character. Could someone help me? Thanks in advance,

 if (String(frm3.subject.value).replace(/ /g, "") == "")  {
            alert("Please enter subject.")
            document.frm3.subject.focus() ;                
        return false; 
    }

One minor change, and you're set:

 if ((frm3.subject.value = String(frm3.subject.value).replace(/"/g, "")) == "")  {
            alert("Please enter subject.")
            document.frm3.subject.focus() ;                
        return false; 
    }

Alternatively, you could just use:

 if (! (frm3.subject.value = String(frm3.subject.value).replace(/"/g, "")))  {
            alert("Please enter subject.")
            document.frm3.subject.focus() ;                
        return false; 
    }

Hi thanks pbmods

sorry i wasn't clear,

the statement above removes the " character, what i want is for an alert to say

"sorry you can't use the " character" i don't want to strip it.

thanks a bunch.

Use the match method instead of replace. See this link.
