Partial View not working propely in index view.

Question

I am developing MVC application and using razor syntax.

In this application I am giving comment facility.

I have added a partial view, which loads the comment/Records from DB.

In below image, we can see the comment box which is called run-time for employee index view.

Now as we can see comment box, I called at run-time, which is partial view, but problem is I can add comment for only on first record...after first record that button wont work at all...

anything is missing ? Is there separate process when we call any partial view run-time and make in action on it ?

See the pic...

Here is the code....

@model PagedList.IPagedList<CRMEntities.Customer>

Answer 1

In success function you need to recall the javascript, or the jquery code that makes the button work. Is an error that taked me a lot of time. Anything uploaded by ajax or any renderpartiAl needs to recall javascript.

$('.RemarkBox').load(url, function() {
  //RECALL JAVASCRIPT

});

Answer 2

To expand on what Alberto León is saying, the partial page load will not cause the document ready event to fire, so the re-rendered elements will not have the javascript event handlers registered after the first comment is added.

To resolve this, you could put the event registration code into a function, and call this both from the document ready event and the success handler of the AJAX call. Something like this:

function AssignEventHandlers() {

    $('a.addremark').click(function () {
        ....
    });

    $("a.pagenumber").click(function () {
        var page = 0;
        page = parseInt($(this).attr("id"));

        $.ajax({
            url: '@Url.Action("GetPagedCustomers")',
            data: { "page": page },
            success: function (data) { 
                $("#customerlist").html(data);
                AssignEventHandlers();
            }
        });
        return false;
    });
}

$(document).ready(function () {

    $('.RemarkBox').hide();

    AssignEventHandlers();
}
