Splitting xmlhttp.responseText row by row?

How can I split up xmlhttp.responseText I receive from a database select row by row? My database layout contains 3 columns which I want to hand over to a function.

This is what the responsetext looks like:

75px, 218px, foo, 12px, 13px, bar, 2开发者_StackOverflow7px, 37px, bla

The function should be called:

myfunction(75px, 218px, foo) 

and so on.

Can anybody show me an example code?

You can "split" the text on the commas:

function handleResponse(rawResponse) {
  function trim(s) {
    return s.replace(/^\s*/, '').replace(/\s*$/, '');
  }

  var attrs = rawResponse.split(',');
  for (var i = 0; i < attrs.length; i += 3) {
    myFunction(trim(attrs[i]), trim(attrs[i + 1]), trim(attrs[i + 2]));
  }
}

edit to actually call the "trim" function I took the trouble to include :-)
