Uncheck all other checkboxes except this one and remove css classes from them

I have a table rows with checkboxes, when I click the row takes the class 'selected' and the checkbox becomes selected.

    $("#emp_grid tbody tr").click(function (e) {
    if (e.target.type == "checkbox") {

        // stop the bubbling to prevent firing the row's click event
        e.stopPropagation();
    } else {
        var $checkbox = $(this).find(':checkbox');
        $checkbox.attr('check开发者_开发技巧ed', !$checkbox.attr('checked'));
        $(this).filter(':has(:checkbox)').toggleClass('selected');              


    }
});

How can I make all the other checkboxes un-selected and remove the 'selected' class from rows except the selected one?

Using your current script something like this should work.

$("#emp_grid tbody tr").click(function(e) {
    $("#emp_grid tbody tr").removeClass("selected");
    $("#emp_grid :checkbox").not(e.target).removeAttr("checked");
    if (e.target.type == "checkbox") {

        // stop the bubbling to prevent firing the row's click event
        e.stopPropagation();
    } else {

        var $checkbox = $(this).find(':checkbox');
        $checkbox.attr('checked', !$checkbox.attr('checked'));
        $(this).filter(':has(:checkbox)').toggleClass('selected');
    }
});

Not sure of the final markup, but it sounds you only want one checkbox selectable? If that is the case maybe a radio button list would be more appropriate instead of a checkbox list?

Update
To allow for toggle of checkbox on row click you can try something like this:

$("#emp_grid tbody tr").click(function(e) {
    $("#emp_grid tbody tr").removeClass("selected");
    var $checkbox = $(this).find(':checkbox');
    $("#emp_grid :checkbox").not($checkbox).removeAttr("checked");
    if (e.target.type == "checkbox") {

        // stop the bubbling to prevent firing the row's click event
        e.stopPropagation();
    } else {
        $checkbox.attr('checked', !$checkbox.attr('checked'));
        $(this).filter(':has(:checkbox)').toggleClass('selected');
    }
});
