layui form 表单赋值

//formTest 即 class="layui-form" 所在元素属性 lay-filter="" 对应的值
 layui.use(['form'], function() {
                //引入layui from模块
                var form = layui.form;
                //为from赋值，赋值方式:"name": "value".
                form.val('formTest ', {
                    "username": "贤心",
                    "password": "123456",
                    "interest": 1,
                    //复选框选中状态
                    "like[write]": true,
                    //开关状态
                    "close": true,
                    "sex": "女",
                    "desc": "我爱 layui"
                });
            })
//注意直接给对象是不能赋值的如下
var data ={
                    "username": "贤心",
                    "password": "123456",
                    "interest": 1,
                    //复选框选中状态
                    "like[write]": true,
                    //开关状态
                    "close": true,
                    "sex": "女",
                    "desc": "我爱 layui"
                }；
              //这样并不能赋值成功
                form.val('example', data);
