jquery parents/closest not working

Question

I have a link which posts some data to a controller. It is working fine and updates the data. But I want to change the css of the parent div but it is not happening. I have tried a lot of variations but I must be doing something stupid.

The code is below

View:

@foreach (var item in Model)
{
    <div class="added-property-excerpt">
        ...
        <div class="added-property-links">
        ...
        @if (!item.IsPropertyDisabled) { 
                @Html.ActionLink("Take off the Market" , "Disable", "Property", new { id = item.PropertyId }, new { id ="disable-link" })
            }
            else {
                @Html.ActionLink("Bring on the Market" , "Enable", "Property", new { id = item.PropertyId }, new { id ="enable-link" })
            }
        </div>
    </div>
}

JQuery

 <script>
     $(function () {
         $('a#disable-link').click(function (e) {
             $('.added-property-links').text('loading...');
             $.ajax({
                 url: this.href,
                 dataType: "text json",
                 type: "POST",
                 data: {},
                 success: function (data, textStatus) { }
             });
             $(this).closest('.added-property-excerpt').css("background", "red");
          // $(this).parent('.added-property-excerpt').css("background", "red");
             e.preventDefault();
         });
     });
 </script>

what does the debugger / log say? could the ajax call throw an exception? — Rudolf Mühlbauer, Oct 14 '12 at 00:34

did you try:

$(this).parents('.added-property-excerpt').css("background", "red");

parents with an s.

What it does is that it goes from parent to parent until it find the class you want.

Good point. I've never used closest but I've now read the documentation. Thanks – VVV Oct 14 '12 at 00:23

Try this

$(function () {
    $('a#disable-link').click(function (e){
        var parentDiv=$(this).closest('.added-property-excerpt');
        $('.added-property-links').text('loading...');
        parentDiv.css("background", "red");
        $.ajax({...});
        e.preventDefault();
    });
});

See the difference in a working example and non-working example.

works perfectly... thanks. But can you tell me why the previous code was not working? – Tripping Oct 14 '12 at 00:52

@Tripping, I think `$('.added-property-links').text('loading...');` line is clearing the `link/ tag` from the dom and `$(this)` was not able to reference it after that line. – The Alpha Oct 14 '12 at 00:55
