function delete_select() {
var chk_value = "";
$('input[name="select_item"]:checked').each(function () {
chk_value += $(this).val() + ",";
});
if (chk_value.length == 0) {
alert('你还没有选择任何内容')
} else {
$.messager.confirm('提示', '您想要删除吗？', function (r) {
if (r) {
$.post("/TeacherList/DeleteSelected", { "id": chk_value }, function (data) {
if (data == "ok") {
$('input[name="select_item"]:checked').each(function () {
$(this).parent().parent().remove();//移除被选中的行
});
$.messager.show({
title: '提示',
