Get opposite/inverse of jQuery .filter() results

I have a.filter function, which works and marks all parents of <td> that contain an input field in red.

However, I need the exact opposite. So return all fields that don't contain <input. I tried if ($(this).html().indexOf('<input') == -1) { but that just marks all rows somehow.

My jQuery:

$(document).ready(function () {
        $("#ListView1_itemPlaceholderContainer table table table td").filter(function (index) {
            if ($(this).html().indexOf('<input') > 0) {
                return true;
            }
        }).closest('div').css('background-color', 'red');
});

Here's my HTML

 <div id="ListView1_itemPlaceholderContainer" style=
  "font-family: Verdana, Arial, Helvetica, sans-serif;">
    <div style="background-color: #FFFFFF; color: #333333;">
      <table style="width: 100%;">
        <tbody>
          <tr>
            <td style="width: 71px"><img id="ListView1_userInfo1_0_ImageUser_0" src=
            "http://pbs.twimg.com/profile_images/13/6GA5kEu6_normal.png" style=
            "height:65px;width:65px;" /></td>

            <td style="vertical-align: top">
              <table style="width: 100%;">
                <tbody>
                  <tr>
                    <td></td>
                  </tr>

                  <tr>

  </div>

I also check out this post jQuery: use filter(), but work with both results as suggested by commenter.

And tried this:

<script type="text/javascript">

    $(document).ready(function () {
        $.fn.invert = function () {
            return this.end().not(this);
        };

        $("#ListView1_itemPlaceholderContainer table table table td").filter(function (index) {
            if ($(this).html().indexOf('<input') > 0) {
                return true;
            }
        }).invert().closest('div').css('background-color', 'red');
    });

</script>

But that also makes all rows red.

回答1:

You can use .not() along with :has()

$(document).ready(function () {
        $("#ListView1_itemPlaceholderContainer table table table td").not(':has(input)').closest('div').css('background-color', 'red');
});

I think you should accept Arun's answer. The problem is that indexOf returns the index of the first match char http://www.w3schools.com/jsref/jsref_indexof.asp, and in your case it will be 0, so the condition > 0 won't apply. Also for what concerns == -1 coloring all the rows, better apply your function to tr instead of td

You can change your function to

$(document).ready(function () {
        $("#ListView1_itemPlaceholderContainer table table table tr").filter(function (index) {
            if ($(this).html().indexOf('<input') > -1) {
                return true;
            }
        }).closest('div').css('background-color', 'red');
});

to mark the rows with input to red, or invert the condition to do the opposite. Or better yet use a different selector as suggested by Arun.

Fiddle for marking red the row with input http://jsfiddle.net/q9othg59/2/ and fiddle for the opposite http://jsfiddle.net/q9othg59/4/
