Issue with .on( 'click', 'tr', function ()

bbrindza · March 26

I have an .on( 'click', 'tr', function () in my DataTable that is not working correctly. When I click one one row and then another , the class active is not remove on previous row.
I suspect it may be the createdRow: function( row, data, dataIndex ) { $(row).addClass( 'total-row' ); }, that I add previously before the function. Looking for a new set of eyes to see what I am missing.
Code below.

<div class='table-responsive tableFont'>
   <table class='table w-100  pt-2' id='timeLogTable_WeekEndingReportByManager'>
      <thead> 
         <tr>
           <th>Approved</th> 
          <th>Approved By</th> 
          <th>Name</th> 
          <th>Emp#</th> 
          <th>Dept</th> 
          <th>Date</th> 
          <th>Time In</th> 
          <th>Lunch Out</th> 
          <th>Lunch In</th> 
          <th>Time Out</th> 
          <th>Hours Worked</th>  
          <th>Lunch Time</th> 
          <th>Total Hours</th> 
          </tr>
       </thead> 
   </table>
</div>

timeLogTable_weekEndingReportByManager = $('#timeLogTable_WeekEndingReportByManager').DataTable( {

Seems to work here: https://live.datatables.net/yegegomo/1/edit .

Can you link to a test case showing the issue please.

Allan

Stand by Allan, Need to build it out. I will post the test case when I completed it.

bbrindza · March 26

Here is the test case https://live.datatables.net/pahocazi/1/edit

However when I add datatables.buttons lib I get this error "Script error. (line 0)"

Maybe you can see what I am doing wrong.

kthorngren · March 26

However when I add datatables.buttons lib I get this error "Script error. (line 0)"

The browser's console (don't use the JS Bin console) shows this error:

Uncaught Cannot extend unknown button type: print

I removed the buttons config as its not needed for the issue you are trying to solve. For demonstration purposes I commented out the select option and added the CSS Allan used in his example:

.active {
  color: blue;
}

The click event seems to be working and toggling the active class:

Please provide the steps to see the issue you aer having. What are you trying to do with the active class?

Hi Kevin ,

I only want to select only one row at a time . The problem with my application on our server is not removing the "active" class from the row that was previously click, which will cause a issue when using the "delete" button in my table. It will keep the "active" class set on any row clicked.

However I noticed that you have commented out the select: {style: 'multi' },

I commented that line out in my script and know I cannot select any rows.

kthorngren · March 27

However I noticed that you have commented out the select: {style: 'multi' },

As I said, I commented this out to show the CSS styling is applied. It is simply for demonstration purposes. Otherwise you wouldn't see the blue text being applied with the selected row.

The problem with my application on our server is not removing the "active" class from the row that was previously click,

@allan 's example uses your code snippet and it works. It works across pages, meaning click a row on page 1 go to 2 click another row and the active class is removed from page 1. The timeLogTable_weekEndingReportByManager.$('tr.active') will find all rows with the active class. There must be something else on your page affecting the active class. Can you provide a test case showing the issue?

Kevin

    $('#timeLogTable_WeekEndingReportByManager tbody').on( 'click', 'tr', function () {
        if ( $(this).hasClass('active') ) {
              $(this).removeClass('active');   alert('Remove active')
       }
        else {
              timeLogTable_weekEndingReportByManager.$('tr.active').removeClass('active');
              $(this).addClass('active');  alert('Add active')
        }
    } );

One thing you can try to verify this code is to place a browser's breakpoint on line 7. Click a row then click another row. At the breakpoint you should be able to verify that the active class was removed from all rows. If this happens but you still have issues then you know the problem is elsewhere.

Kevin

kthorngren · March 27

I updated @allan 's example with Select. You can still see that the active class is removed.
https://live.datatables.net/yegegomo/3/edit

If it weren't removed the previously clicked row text would be blue.

Kevin

kthorngren · March 27

Even easier than using a browser's breakpoint is to temporarily add the CSS Allan tested with. You should never see teh blue text if the active class is prperly removed.

I found the culprit. I was missing the js select: true, Thank you all for you help
