reg ex help ...

[aapun]

I want to split a string of numbers into an array of four characters each...
This is what i did:

<SCRIPT LANGUAGE="JavaScript">
<!--
str="49384389749848748234343343433"
re = new RegExp("[0-9]{1,4}", "g");
alert(str.split(re))
//-->
</SCRIPT>


returns nothing :(

Any feedback ???

You don't use split(), you use this:

re.exec(str);

Jona,
thank you for the lead.


I tried this as per your suggestion.
alert(str.split(re))

It shows only the first four characters. I dont get the entire array. Am i missing something in my reg ex ??? Do i need to mention a star somewhere. How do i make him split after the first four characters ?? :rolleyes:

You are using split(), you should be using:

alert(re.exec(str));

oops my bad, typo !!
I tried this... it displays only the first 4 chars

<!--
str="49384389749848748"
re = new RegExp("[0-9]{1,4}", "g");
//alert(str.split(re))
alert(re.exec(str))
//-->

This part: {1,4} is what makes it only allowed to go through the first 4 characters. Take that out and see what happens.

P.S. This is Jona (not at home).

var str = "49384389749848748234343343433";
var re = new RegExp("\\d{1,4}", "g");
alert(str.match(re));

Bit long-winded, but it works.

myRe=/\d{4}/g;
str="49384389749848748";
strlen = Math.ceil(str.length/4)
var Ary = new Array();
for (i=0; i<strlen; i++) {
Ary[i] = myRe.exec(str);
alert(Ary[i]);
}

There must be a better way!! :)

jeff post appeared after I posted. I knew there was a better way :D
