[quicksearch] How to determine number of displayed

问题:

I'm using jQuery with TableSorter and QuickSearch plugins. These work fine.

How can I:

1. dynamically display row numbers for each displayed row?

2. somewhere on my page, display the total number of displayed rows?

回答1:

 $('tr:visible').length

Will you give the number of visible rows on the page.

Something along the lines of:

 var rowCount = $('tr:visible').length;
 $('#rowCountDiv').html(rowCount + "rows");

Will write out the number into a div on your page with an id of rowCountDiv

Here's the proper answer. In the PHP use something like this:

echo "Dynamic count: <p id=\"count\"></p>";

Then in the quickSearch add an onAfter function.

onAfter: function() {
    document.getElementById("count").innerHTML=($('tr:visible').length-1);
}

Voila! Now you have a dynamic count that updates whenever the table is searched.
