Question

This is the fragment of code inserted with ajax:

<form>
    <label for = "task-name">Name</label>
    <input type = "text" id = "task-name" />

    <label for = "task-description">Description</label>
    <input type = "text" id = "task-description" />

    <input type = "hidden" id = "task-col" />
    <input type = "hidden" id = "task-row" />

    <input type = "submit" id = "add-task" onclick="return false" value="Add" />

</form>

This is the JS code which insert the previous element in the DOM:

$('html').on('click', '.task-pop', function(){
    var pos = $(this).parent().parent().attr('class').split("-");
    ajaxObj = getXmlHttpObject();
    ajaxObj.onreadystatechange = function(){
        if(ajaxObj.readyState == 4 && ajaxObj.status == 200){
            $('#pop-hold').html(ajaxObj.responseText);
            $('#task-col').val(pos[0]);
            $('#task-row').val(pos[1]);
        }
    };
    ajaxObj.open("GET","resources/component/newTask.jsp");
    ajaxObj.send(null);

    $('#pop-blk').css('display','block');
    $('#pop').show("fast");
});

As you can see I’m trying to add some values to the hidden inputs #task-row and #task-col from the content added dynamically.

The page is properly displayed and no error is thrown but those two fields are never accessed. How can I solve this?

change

$('#pop-hold').html(ajaxObj.responseText);
$('#task-col').val(pos[0]);
$('#task-row').val(pos[1]);

with

var html = $(ajaxObj.responseText);
html.find('#task-col').val(pos[0]);
html.find('#task-row').val(pos[1]);
$('#pop-hold').html('').append(html);
