Hello,

I have 1 problem , I've taken one jquery plugin (filter on table).

This is URL : http://gregweber.info/projects/demo/flavorzoom.html

But I have a little bit different case:

Instead (textbox) I use (dropdawn menu)

 <select class="filter_tb">
    <option value="">All</option>
    <option value="6-K">6-K</option>
    <option value="20-F">20-F</option>
    <option value="SC 13G/A">SC 13G/A</option>
    <option value="SC 13G">SC 13G</option>
    <option value="F-10/A">F-10/A</option>
    <option value="F-X">F-X</option>
    <option value="F-10">F-10</option>
</select>

I'm doing filter by value, but this is a problem: When I select "SC 13G" in the table of course is displaying "SC 13G/A" .

Can I stop this one ? I want to display just "SC 13G" the same one is for "F-10 --- > F-10/A"

This is My jquery selector :

$(function() { 
  var theTable = $('table.RegulatoryFilingsTable')


  $(".filter_tb").change(function() {
    $.uiTableFilter( theTable, this.value );

  });


});

If it is possible, help me

Thanks

For your scenario the plugin may be overkill. You can achieve the desired effect with the jQuery snippet below:

$(".filter_tb").change(function() {
    $(".food_planner tbody tr td:nth-child(2)").each(function () {
        if ($(this).text() != this.value) {
            $(this).parent().hide();
        } else {
            $(this).parent().show(); 
        }
    });
});

If you would like to use the plugin, you can make it work by modifying the following lines:

Line 26: var words = phrase.toLowerCase().split(" "); to var words = phrase.toLowerCase();

Line 87: if (text.indexOf(words[i]) === -1) return false; to if (text != words[i]) return false;

something is wrong in script, it is hiding all rows, not just parent row

Thanks, i fixed, Thanks a lot for a good idea...

So if you are wanting to simply do an exact match the filter might be a bit of overkill but here is an extra function to add to it to do just that:

jQuery.uiTableFilter.is_word = function( str, words, caseSensitive )
{
    var text = caseSensitive ? str : str.toLowerCase();
    if(text == words) return true;
    return false;
}

Here is my full code I used for testing:

<html>
    <head>
        <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.3.2/jquery.min.js"&gt;&lt;/script&gt;
        <script type="text/javascript" src="./tablefilter.js"></script>
        <script type="text/javascript"> 
            $(document).ready(function()
            {                
              var theTable = $('table.RegulatoryFilingsTable');
              $(".filter_tb").change(function() {
                $.uiTableFilter( theTable, this.value );
              });
            });
        </script>
    </head>
    <body>
         <select class="filter_tb">
            <option value="">All</option>
            <option value="6-K">6-K</option>
            <option value="20-F">20-F</option>
            <option value="SC 13G/A">SC 13G/A</option>
            <option value="SC 13G">SC 13G</option>
            <option value="F-10/A">F-10/A</option>
            <option value="F-X">F-X</option>
            <option value="F-10">F-10</option>
        </select>

        <br/><br/>

        <table class="RegulatoryFilingsTable">
            <thead><tr><th colspan="2">Your List</th><tr></thead>
            <tbody>
                <tr><td>6-K</td></tr>
                <tr><td>20-F</td></tr>
                <tr><td>SC 13G/A</td></tr>
                <tr><td>SC 13G</td></tr>
                <tr><td>F-10/A</td></tr>
                <tr><td>F-X</td></tr>
                <tr><td>F-10</td></tr>
            </tbody>
        </table>
   </body>
</html>

And the whole of the modified table filter script (which I called tablefilter.js):
