Check/Uncheck Select All header checkbox using jquery


i wanted to check or uncheck  SelectAll header checkbox on specific condition. so how can i check do that programmatically.

I found some workaround to do it programmatically.

$('#ig1').find('[name="hchk"]').data("chk","off").find("span").removeClass( "ui-igcheckbox-normal-off" ).addClass( "ui-igcheckbox-normal-off" );

but above work around fail when checkbox clicked and checked previously and using above code i unchecked it and then clicked to checked that time it actually perform deselection of rows but it must perform Selection of all rows.

    jQuery is() method is to check the current matched set of elements against a selector, element, or jQuery object and return true if at least one of these elements matches the given arguments.

    if ($("input[type=checkbox]").is(":checked")) {
