    Start with this delegated events example. Here is an example with buttons:

    You have #compile which doesn't seem right as the IDs need to be unique on the page. If you still need help please build a simple test case showing what you are trying to do so we can offer specific suggestions.

    #compile - do you have an element with id="compile" in every row? That isn't valid HTML, each id must be unique.

    I would suggest you use a class name rather than an id.

    To get the data of a cell you can use cell().data() or for the whole row row().data().

    If you link to a test case showing the issue, I'll be able to help further.

    but if I use clause $(this) it doesn't referred at that specific row?
    Yes I've id inside each TR

  • kthorngrenkthorngren Posts: 20,278Questions: 26Answers: 4,766

    Maybe use jQuery closest(), like this $(this).closest('tr).

    The best next step is for you to build a simple example showing what you have or provide a link to your page. This way we can have an understanding of your solution to provide specific suggestions.

    I updated my above example so that each row has an id. When clicking the button it will output the row id to the console:

    "targets": [ 6 ],
    "visible": false
    Is it possible get that information inside it?

  • kthorngrenkthorngren Posts: 20,278Questions: 26Answers: 4,766

    Use cell().node().

    No works...td isn't in the DOM but is in the cache.

  • kthorngrenkthorngren Posts: 20,278Questions: 26Answers: 4,766

    That is why you use cell().node(), like this:

    My example works. If you are having difficulties using cell().node() then provide an example of what you are trying to use so we can help. Or if my test case is not doing what you want then let us know what you are expecting.

    I'm so sorry about it. I've moved all code together in js file. So before code was split in two parts.Now works , i got .data() instead .node()
