Saya memiliki fungsi di bawah ini yang hanya ingin saya picu ketika kotak centang di tr yang sama dicentang. Tolong beritahu saya apa yang saya lakukan salah, metode yang biasa tidak berfungsi. Terima kasih
JS
$(".add_menu_item_table").live('click', function() {
var value_td = $(this).parents('tr').find('td.td_name').text();
if ($('input.checkbox_check').attr(':checked')); {
var newDiv = $('<div class="div_menu_button"></div>');
var showDiv = $('<div id="show' + "0" + numShow++ + '" class="menu_button_info hidden"></div>');
var toggleTrigger = $('<a id="toggleshow' + "0" + numToggle++ + '" data-target="#show' + "0" + numTarget++ + '" class="toggle_trigger actions"> </a><div style="padding:5px"></div>');
var menuForm = $('<form id="menu_edit_form' + "0" + numForm++ + '" class="menu_creation_form"></form>');
$('#created_buttons_list').append(
newDiv.text(value_td)
);
newDiv.wrap("<li></li>");
newDiv.append(toggleTrigger);
newDiv.append(showDiv);
showDiv.append(menuForm);
menuForm.html('<label for="navigation_label">Navigation Label</label><input id="navigation_label' + "0" + numLabelone++ + '" type="text" placeholder="Navigation Label" name="navigation_label"><label for="attribute">Attribute</label><input id="attribute' + "0" + numLabeltwo++ + '" type="text" type="text" placeholder="Attribute" name="attribute"><label for="url">URL</label><input id="url' + "0" + numLabelthree++ + '" type="text" type="text" placeholder="URL" name="url"><input type="button" value="Remove" class="button_link remove_button"> <input type="reset" value="Cancel" class="button_link">');

$('input.checkbox_check').checked
kembalitrue
jika sudah dicentang,false
sebaliknya
