Read Checkbox checked property from HTML

Question

I have an aspx page which renders as below.

<div id="div1">
<tr>
<td>SomeTxt</td>
<td><input checked="checked" class="check-box" disabled="disabled" type="checkbox" /></td>
<td>text2</td>
</tr>
</div>

Iam trying to read checkbox checked property from javascript :

var status = $('#div1 tbody tr:eq(' + tr.rowIndex + ') td:eq(1)').checked;

But I am getting undefined.

Answer 1

使用is(':checked')

var status = $('#div1 input[type="checkbox"]').is(':checked');

Answer 2

Something like this

var status = $("input[type='checkbox']:checked").val();
alert(status);

Answer 3

TD将不具有选中的属性，必须选择输入元素。

Answer 4

you can use:

$("#yourID").is(":checked")

Make sure give an ID to your checkbox, not taking it <tr>

Answer 5

td:eq(1) will return td and not the input element

var status = $('#div1 tbody tr:eq(' + tr.rowIndex + ') td:eq(1)').find("input").get(0).checked;
