Errors occurred when trying to use Jquery to handle a JSON response

enter code here

function customPaging(action, action1, page) {

alert("in customPaging");

$.getJSON("./paging.do?action="+escape(action)+"&p="+escape(action1)+"&str="+escape(page), 

function(data){

alert("Length: "+data.length);

var options = '';

for (var i = 0; i < data.length; i++) {

options += '<option value="' + data.key + '">' + data.data + '</option>';

}

$("#selectCol").empty();

$("#selectCol").html(options);

}); 

}

This particular function gets triggered when an element is clicked. It successfully makes a call to the server but I am not receiving any response data back. Can someone please investigate and provide assistance?

Thank you in advance. Raju

Answer №1

One helpful tip is to install firebug and analyze the ajax calls and responses on the net tab.

If your Json appears to be incorrect or if the server has returned an error code such as 500 or 404, these could be potential issues to investigate.
