Events assigned to the table can be exceptionally useful for user interaction, however you must be aware that DataTables will add and remove rows from the DOM as they are needed i.
As such, this can lead to the odd hiccup when working with events. One of the best ways of dealing with this is through the use of delegated events with jQuery's on method, as shown in this example.
Handling DataTable Events
This table loads data by Ajax. The latest data that has been loaded is shown below. This data will update automatically as any additional data is loaded. The script used to perform the server-side processing for this table is shown below. Please note that this is just an example script using PHP.
What is happening is that on row click event is happening before datatables selection occurs. How can I fix this? I need the current selected row inside onclick event.

Sign In or Register to comment.You may need to handle clicks or other events in a table powered by jQuery DataTables plug-in. However if the event handler is attached incorrectly, it will not be called for pages other than first or when the table is sorted or filtered.
This is one of the most common problems users have with jQuery DataTables plug-in and it has very simple solution if you understand why it occurs.
Table below demonstrates the problem with attaching event handlers incorrectly. According to jQuery on documentation:. Event handlers are bound only to the currently selected elements; they must exist at the time your code makes the call to. Our code above worked only for the first page elements because elements from other pages were not available in DOM at the time the code was executed.
The solution is to use event delegation by providing selector for target element as a second argument in on call, see example below. Delegated events have the advantage that they can process events from descendant elements that are added to the document at a later time. We attach event handler to the table ' example' and specify a selector for the button '. Event handler will now be called for all buttons whether they exist in DOM now or added at a later time.
I design and develop custom websites and web applications, perform website maintenance and provide technical support for small and medium-sized businesses. I have a function call to a. Works on the first page, not on subsequent. Using id attribute closeStatus for more than one select element is not recommended, you need to use class instead. For example, for table with ID example and multiple select elements with class closeStatus :. I will publish this example on JSFiddle sometimes today or tomorrow so that it would be easier to see the code.
My problem was similar to Chad M and your answer worked for me. Thank you so much Michael Ryvkin! DataTables in general and pagination in particular has caused me countless hours of frustration. I wonder if you have an answer to the issue of pagination on for instance page 4 jumping back to page 1 when some a checkbox is clicked and thus the form is submitted.
Just asking, so I appreciate any insight you can provide.

jQuery DataTables: Why click event handler does not work

DOM / jQuery events
September edited September Here is my code. Howdy, Stranger! It looks like you're new here.The DataTable object provides a series of events that can be processed by an application.
The following table describes DataTable events. Most operations that add or delete rows do not raise the ColumnChanged and ColumnChanging events. Data corruption can occur if data is modified in a DataSet from which the RowChanged event is raised.
No exception will be raised if such data corruption occurs. The Constraints property holds a ConstraintCollection instance.
The ConstraintCollection class exposes a CollectionChanged event. This event fires when a constraint is added, modified, or removed from the ConstraintCollection. The Columns property holds a DataColumnCollection instance. Modifications that cause the event to fire include changes to the name, type, expression or ordinal position of a column.
These events fire when a DataTable is added to or removed from the DataSet. Changes to DataRows can also trigger events for an associated DataView. The DataView class exposes a ListChanged event that fires when a DataColumn value changes or when the composition or sort order of the view changes. Here is the sequence of operations that occur when a DataRow is added, modified, or deleted:. Changes to expression columns never raise DataTable events. Expression columns can have dependencies on multiple other columns, and can be evaluated multiple times during a single DataRow operation.
Each expression evaluation raises events, and a single DataRow operation can raise multiple ListChanged and PropertyChanged events when expression columns are affected, possibly including multiple events for the same expression column. Each event handler displays output in the console window when it is fired. Skip to main content. Exit focus mode. This event is intended primarily to support design-time scenarios.
ColumnChanged Occurs after a value has been successfully changed in a DataColumn. ColumnChanging Occurs when a value has been submitted for a DataColumn. TableClearing Occurs after the Clear method is called but before the Clear operation begins.
Disposed Occurs when the DataTable is Disposed. Inherited from MarshalByValueComponent. Note Most operations that add or delete rows do not raise the ColumnChanged and ColumnChanging events. Warning Data corruption can occur if data is modified in a DataSet from which the RowChanged event is raised. Note Changes to expression columns never raise DataTable events. Is this page helpful? Yes No. Any additional feedback? Skip Submit. Occurs after the EndInit method of a DataTable is called.
Trouble is that the ajax call happens automagically and I'm not the one creating the rows in the table. Learn more. Asked 4 years, 11 months ago. Active 1 year, 10 months ago. Viewed 35k times.

Errors in your fiddle: You use datatables method call but have only added the bootstrap-table library. Ajax is not working in the fiddle, but we can ignore that for now. To bind the event also for table rows which will be inserted by datatables, bind it to the table and use tr as selector in the on method.
If you want to find an element by id you need to use the. But beware that you can't use ids if there are multiple elements, use a class instead. Table cells have no value, so use text instead of val.

Since we are attaching the event directly to the GridView Row which by default does not have any OnClick event, you might land into the following error.
