layui 弹出层回调获取弹出层数据的例子

// 弹出楼栋负责人信息页面   layer.open({   type: 2,   title:'请选择楼栋负责人',   maxmin: false,   area: ['60%', '80%'],   offset: '0px',   content: '${ctx}/life/houserInsertion/headBuildingInfo?pkProject='+pkProject,   btn: ['确定','关闭'],    yes: function(index){    //当点击‘确定'按钮的时候，获取弹出层返回的值    var res = window["layui-layer-iframe" + index].callbackdata();    //打印返回的值，看是否有我们想返回的值。    console.log(res);    for (var i = 0; i < res.length; i++) {    var html = "<div class='text' value='' style='visibility: visible;'>" +     "<p>" + "<span class='responsibleName' value=" + res[i].value + ">" + res[i].title + "</span>" +     "<a class='close_btn' οnclick='remove(this)'>" + 'X' + "</a>" + "</p>"    "</div>"    $("#responsibleName_id").append(html);        }    //最后关闭弹出层    layer.close(index);   }   });// 关键代码var res = window["layui-layer-iframe" + index].callbackdata();这行代码中‘callbackdata'是弹出层里面定义的函数。也许我们知道了什么！这个函数的作用就是返回值。弹出层定义callbackdata函数var callbackdata = function () {  var data = {  username: 'zhangfj',  age:12,  address:'广州'  };  return data; }
