Question

I have the following html that renders within an ASP.NET Repeater:

<div class="divDE-item" onclick="addFilter(this);">
  <span class="spnKey">Some key</span>
  <div>1234</div>
</div>

I realize that having an onclick on the outer div may not be the most graceful jQuery-centric approach. However, considering my situation, it works well.

Here is my addFilter() function:

function addFilter(oDiv) {
  $(document).ready(function() {
    // Get and set the prefix text for the label. i.e. "Key = "
    sDEName = $(oDiv).find("span").text();
    $('#<%= lblDEName.ClientID %>').text(sDEName + " = ");

    // Get the actual filter text value. i.e. "1234"
    // sFilter = $(oDiv).text();
    var sFilter = $(oDiv).filter(function() {
        var filtered = $(this).not(".spnKey");
        return filtered
    });

    $('#<%= txtValue.ClientID %>').val(sFilter);
  });
}

The goal is for the output to appear like this (with 1234 being the value of a textbox):

Some key = 1234

However, the output I’m getting is: Some key = Some key 1234

You don’t need to call filter.

You can simply write $('div:not(.spnKey)', oDiv).text().

To answer your question, you’re using filter and not wrong. The filter method returns a jQuery object containing some of the elements in the one you call it on. (Not their children). To use it this way, you should call $(oDiv).children().filter(...).

The not method is the opposite of filter, and returns the elements in the jQuery object that don’t match a selector of function. You could therefore also write $(oDiv).children().not('.spnKey').
