string validation - easy one

[tlynch]

I need to check a string to make sure it includes a period "." and does not include an "@" or spaces but it doesn't matter what else is in it.

Any help is appreciated.

Thanks in advance.

VBScript (Client-Side) or JavaScript?

thansk for the quick reply - javascript

Ack.

Sorry, but i'm afraid I can't help much. With VBScript and stuff I can do it in a snap, but my JavaScript skills are VERY VERY rusty.

I'll turn this thread over to one of our resident JS gurus now.

Sorry that I couldn't help.

Good luck with your Scripting!

Hey guys,

To detect if a string contains a character, you can use indexOf. Here's an example:

str="this is a new string with @ and, of course, spaces";

if(str.indexOf(".")==-1 || str.indexOf(" ")!=-1 || str.indexOf("@")!=-1){
alert('This string is not in the correct format');
}

Hope that helps,

You can also use regular expression in Javascript to check whether a string contains " . " and anything else other than "@"

<script language="javascript1.2">
re = /^[\w\d\.]+.[\w\d\.]+$/
myString = "abc@ew e";
if (re.test(myString)) {
alert("valid string!");
}
else{ alert("invalid string!"); }

myString2 = "accept.this";
if (re.test(myString2)) {
alert("valid string!");
}
else{ alert("invalid string!"); }

</script>

This regular expression accepts any letter or digit and at least a period. Probably not very complete, but you can go here for more reference: http://developer.netscape.com/docs/m...ide/regexp.htm
