Unescape comma 1

[jianhua]

Hi,

I tried to validate a text field to see whether the string contains a comma or not. If there is no comma in that string, alert box appears. Now the problem is that I cannot unescape comma. My code is as follows:

function upd_info(f){
var err = true;
for (var i=0; i < f.elementname.value.toString().length; i++){
var oneChar = f.elementname.value.toString().charAt(i);
if (oneChar == &quot;,&quot{ //also tried if (oneChar == unescape(&quot;%2C&quot)
err = false; break; }
}
if (err == true){
alert(&quot;You must have a comma to separate the last name and the first name.&quot;
return(false);
}
return(true);
}

Thanks in advance...

Why not use:
function upd_info(f){
if(f.elementname.value.indexOf(&quot;,&quot>-1){
alert(&quot;You must have a comma to separate the last name and the first name.&quot;
return false;
}
return true;

Thanks Adam!!!

It's working... and I changed it to
if(f.elementname.value.indexOf(&quot;,&quot == -1)

Thanks again!!!!!
