Resolved - Evaluate the first 4 characters in a string?

[jesus4u]

How can I do this?

Let's say the string..

var strString = "12.This is it"

How can I test if the first 2 chars are numbers and then there is a [.] after it?

Thanks

I'd use regular expressions (Javascript in newer browsers has Perl style RegEx syntax, same as VBScript).

if ( /^\d{2}\./.test(strString) ) {

}

I appreciate that. But the strings will not always be the same. It will be like this:

1.sdfsddsfsdf
2.dfsdfsdfdsf
3.sdfsdf

etc...

Why is the code still finding a match for the [.] when it is not in the string?

<SCRIPT LANGUAGE=javascript>
<!--
	var strString = "12this is it"
	if ( /^\d|\d\./.test(strString) ) {
		alert(strString)
	} 

//-->
</SCRIPT>

How can I look for either occurence of 12 or 1 in the string?
Because so far only will find 2 occurences first.

<SCRIPT LANGUAGE=javascript>
<!--
	// / beginning and end of what is evaluated
	// \d = [0-9]
	// \s =  space
	// \ separator
	
	var strString = "1. this is it"
	if ( /^\d|\d\.\s/.test(strString) ) {
		alert(strString)
	} 

//-->
</SCRIPT>

NEver mind , got it!

<SCRIPT LANGUAGE=javascript>
<!--
	// / beginning and end of what is evaluated
	// \d = [0-9]
	// \s =  space
	// \ separator
	
	var strString = "12. this is it"
	if ( /^\d{1,2}\.\s/.test(strString) ) {
		alert(strString)
	} 

//-->
</SCRIPT>
