Jquery find a checkbox inside a table row -


my html

<tr class="datarow" id="rowid"><td>1</td><td>895171</td><td class="classid"><input type="checkbox" /></td></tr>

how use jquery find out whether checkbox in particular row checked or not. assume know unique rowid.

currently, doing this

var checkbox = $('#' + rowid + " td input:checkbox");          if (checkbox.checked) {            alert("checked");         } else {            alert("unchecked");         }

but doesn't seem detect when checkbox checked.

edited curiously, following didn't work either:

        var currow = $('#' + currowid);         var checkbox = $(currow).find('input:checkbox').eq(0);            if (checkbox.checked) {            alert("checked");          } else {            alert("unchecked");          }

you can this:

var ischecked = $("#rowid input:checkbox")[0].checked;

that uses descendant selector checkbox, gets raw dom element, , looks @ checked property.

references selectors:

  • selectors supported browsers: css 2.1
  • newer selectors supported browsers , various javascript libraries (for interacting dom): css3 selectors
