layerUI子頁面和父頁面交互，實現動態添加參數到父頁面。前端代碼如下：
父頁面index.html

$("#submitAll").click(function (){

var index = parent.layer.getFrameIndex(window.name); //獲取窗口索引
var tabVal = new Array();
$("#idUserTable tbody").find("tr").each(function(){

var val = $(this).find("input[name='likeClass']").val();
var backStr='<input type="text" id="'+id+' "value="'+val+'"/>';

parent.layer.close(index);

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
@Controller
public class HelloController {

public String hello() {
