You have to add “.button(‘refresh’);” to change view of the button.
<script>
$(document).ready(function()
$(“#data_delete_btn”).attr(‘disabled’,’disabled’);
$(“#delete_button_checkbox”).click(function()
if ($(this).is(‘:checked’))
$(“#data_delete_btn”).removeAttr(“disabled”).button(‘refresh’);
else
$(“#data_delete_btn”).attr(‘disabled’,’disabled’).button(‘refresh’);
);
);
</script>
