append row after first row in a html table

Question

I have var row=<tr><td>val</td><td>val2</td></tr> and I tried this:

$("#mainTable tbody").append(row);

but it appends to the end of the table.

Also I tried $("#mainTable tr:first").after().append(row);

But have not got a result yet.

Please, help me to understand.

Try this:

$("#mainTable tr:first").after(row);

InsertAfter is what you are looking for:

var row='<tr><td>val</td><td>val2</td></tr>';
$(row).insertAfter("#mainTable tr:first");

Answer 3

You can use prepend JQuery method that inserts as the first child:

$("#mainTable tbody").prepend(row);
