layui type2 通过url给iframe子页面传值的例子

 layui.use(["layer"], function () {
 layui.layer.open({
 type: 2,
 title: "管理角色拥有的部门",
 btn: ["确定修改", "关闭"],
 content: '@Url.Content("~/Role/UserRoleView?rid=")'+a[0].ID + '&uid=' + a[0].UID,//这里指向office
 btn1: function (index, layero) {
 //获取子页面数据
 var body = layer.getChildFrame('body', index);
 var addData = body.find("#listFalse li");
 console.log(addData);
 var delData = body.find("#listTrue li")
 console.log(delData);
 if (addData.length==0&&delData.length==0) {
 layui.layer.closeAll();
 layui.layer.msg("没有做任何修改！");
 return false;
 } else {
 var url = '@Url.Content("~/Role/AddRemoveUsers2Role")';
 if ($(addData).find("span").length != 0) {
 var data = getListData(addData);
 $.ajax({
 type: "post",
 url: url,
 data: { "rid": a[0].ID, "uids": data },
 success: function (rst) {
 layui.layer.closeAll();
 layui.layer.msg("添加用户成功，其用户名分别为：" + data.toString());
 
 }
 })
 };
 if ($(delData).find("span").length != 0) {
 var data = getListData(delData);
 $.ajax({
 type: "post",
 url: url,
 data: { "rid": a[0].ID, "uids": data ,"Add":"false"},
 success: function (rst) {
 layui.layer.closeAll();
 layui.layer.msg("删除用户成功，其用户名分别为：" + data.toString());
 }
 })
 }
 }
 },
 btn2: function () {
 layui.layer.closeAll();
 }
 
 })
 })

 //页面初始化
 
 $(function () {
 var oid = args().oid;//获取父页面oid
 })
 //获取index传参rid args为传递过来的所有参数，类型为OBJDECT，调用为args();
 var args = function(params){
 var a = {};
 params = params || location.search;
 if(!params) return {};
 params = decodeURI(params);
 params.replace(/(?:^\?|&)([^=&]+)(?:\=)([^=&]+)(?=&|$)/g,function(m,k,v){ a[k] = v; });
 return a;
 };
