Regex - Only want to use certain part ??

[JChilds]

I'm using the code:

 

javascript:
var report = document.body.innerHTML;
var ID = report.match (/id_\d{1,9}/g);
alert(ID,"");

 

To extract everything matching id_XXXXXXX where x is anywhere from 1 to 9 numbers.

 

It returns an array perfectly. But it returns it like "id_1234567, id_6472826, id_7998326"

And i want it to return it like "1234567, 6472826, 7998326"

 

Is there an easy way to go about doing this?

Hmmm, I would think you could achieve that with a modified RegEx, but I couldn't figure it out. Here's a quick fix:

 

function getIDs (string) {

  var IDs = string.match (/id_\d{1,9}/g);
  for (var i=0; i<IDs.length; i++) {
    IDs[i] = IDs[i].substr(3);
  }
  return IDs;
}

var ID = getIDs (document.body.innerHTML);

Thanks for that 

 

I've been playing with regex's for the last few hours and can't figure it out  :'(

 

I'll leave this thread 'open' for a little longer and see if anyone else can get it to work.

 

All of this code is going on one line (I only have access to one button - nothing else)

And in total, its already half an A4 page of code. So don't want to make it worse for myself.

Using a reg ex:

  I used:  /([0-9]+)$/    -- to me means: Ends with any amount of numbers 0-9.

<script type="text/javascript">
var myA = new Array("id_12345","id_142442","id_124125");
  var x = myA.length;

for(i=0;i<x;i++)
{
  var str = myA[i].match(/([0-9]+)$/);
  if(str) {
    myA[i] = str[0];
  }
}

for(a=0;a<myA.length;a++)
{
  document.write(myA[a] + '<br />');
}//returns just the numbers
</script>

 

 

If the array always holds values of id_#####  where the "id_" is guaranteed to be there and then followed by a random amount of letters, you could just use a substr method like posted above.
