使用jquery获取表的特定行的值

Question

How can I get a specific row value of a table(for exampe third row of fifth column) using jquery. I tried:

var t = document.getElementById('table');

    var val1 =$(t.rows[2].cells[4]).val();
    alert(val1);

But it is showing nothing

Answer 1

Try using :eq() selector at this context

.val() is only applicable for input elements, you should use .text() instead to retrieve its text content,

var val1 =$(t).find('tr:eq(2) td:eq(4)').text();
alert(val1);

Or do,

alert($('#table tr:eq(2) td:eq(4)').text());

Answer 2

.val is for textBox, textAreas, use .text instead like bellow.

That should be something like bellow

alert($('table tr').eq(2).find('td').eq(4).text())

I've added the selectors according to my DEMO, please change it accordingily, because I don't have your HTML

Answer 3

Assuming you want to access 5th column in 3rd row ,

You can use :eq() selector like

var value= $("#table tr:eq(2) td:eq(4)").text();

Side note: val() is used for accessing the value of form controls.
