Email Address Validation

[ami7]

Hi all,

In my .aspx page i have a textbox in which email address will be entered.
For validating the email address i have got this javascript.
But how to implement this here.
I know there is a property in the custom validator to enter
ClientValidationFunction.

Can anyone tell me how to use this code in my appln.


javacode:
function validEmail(objEmail) {
var strEmail = ""+objEmail.value;
var errorStr = "";
var atCount = 0;
for (var i=0;i<strEmail.length;i++) {
if (strEmail.charAt(i) == &quot;@&quot atCount++;
}

var emailFilter=/^.+@.+\..{2,3}$/;
if (!(emailFilter.test(strEmail)) || atCount > 1 || strEmail.indexOf(&quot;..&quot!=-1) {
errorStr = &quot;Please enter a valid email address.\n&quot;;
alert(errorStr);
highlightField(objEmail);
return false;
}

var illegalChars= /[\(\)\ \{\}\!\%\£\¬\`\'\?\$\^\&\*\|\#\=\+\<\>\,\;\:\\\/\&quot;\[\]]/;
if (strEmail.match(illegalChars)) {
errorStr = &quot;The email address contains illegal characters.\n&quot;;
alert(errorStr);
highlightField(objEmail);
return false;
}
return true;
}
Thanks,
ami.

Instead of using a custom validator, use a regular expression validator. You just tell the validator which field you want it to validate, put in the regex as one of the validator's properties, and let 'er rip.
