javascript - Datatables: Select row with given ID - Stack Overflow

文章数量:1355645

I've set up a datatables plugin and created a new table from an JSON file:

var table= $("#mytable").DataTable({

    ajax: "list.json",
    columns: [
        {"data": "name"},
        {"data": "location"},
        {"data": "date"}
    ]
}); 

Now I want to add an .active class to a row with a given id:

table.on( 'xhr', function () {
  table.row("#id_1").addClass("active");
}

(the id's for the rows has been defined during the plugin setup and are in place). However, I get this error:

undefined is not a function

like it can't find a row with this ID, however I do have it. Any ideas?

• 3 table.row("#id_1") may not be returning jQuery wrapped object.. Try $(table.row("#id_1")).addClass – Rayon Commented Apr 18, 2016 at 6:11
• Rayon, that was a very good point! You are my saviour again. Luca pleted the answer with a mention of node() too! Thank you very much! I have a lot to learn yet. – sdvnksv Commented Apr 18, 2016 at 6:20

The Datatables .row() method doesn't return a DOM Node, you need to get it with .node() after selecting it.

var row = table.row("#id_1").node(); $(row).addClass('active');

Datatables .row()

Datatables .node()
