Question

jquery looks like this

    $.post('JSP/processForm.jsp', $("#Form").serialize(),
          function(data){
          //I want to iterate through every line in the data object returned here.

   });

I searched and tried:

$.each($(data), function(key, value) {
      alert(value);
});

But that did not work. I understand the response needs to be encoded into a jQuery object first.

$(data)

But i just can’t seem to find a way to iterate through every line. The jsp code is simply:

out.println("Test");
out.println("Test Email");
out.println("Test CellPhone");
out.println("305-777-5587");

A few things to note:

• Your jsp is likely being rendered and returned with a header that suggests it’s html content. You are (somewhat arbitrarily) deciding that each new line of text represents a new piece of data.
• jQuery each documentation shows it only works on a collection, so jQuery wrapping your object isn’t necessary. (http://api.jquery.com/jQuery.each/) However, jQuery has no method by which to parse your returned html into a javascript collection object.
• If you are truly trying to end up with a javascript structured data object, you may consider sending your output as JSON (javascript object notation). From what I’ve seen, it seems more fitting in this case.

If you did want to continue this way, you’d need to write some javascript to split your response html at the new line. It would likely look like this (you may need to play around with it)

var myData = data.split(/\r\n|\r|\n/);
