3、表单填充值
使用方法
<script type="text/javascript"> layui.config({ base: '../Scripts/layui-expand/' //插件路径 }).extend({ enhanceform: 'enhanceform' }); layui.use(['form', 'enhanceform'], function() { var form = layui.form, enhanceForm = layui.enhanceform; var enhance = new enhanceForm({ elem: '#mainForm' //表单选择器 }); /** * 设置select选中值 * @param {String} name 对象名称，指“name” * @param {String} val ֵ * @param {Boolean} isOnSelect 是否触发选中事件 * @returns {} */ 1、enhance.setSelectVal /** * 设置radio选中 * @param {String} name 对象名称，指“name” * @param {String} val 对象值 * @returns {} */ 2、enhance.setRadioVal /** * 设置checkbox选中 * @param {String} name 对象名称，指“name” * @returns {} */ 3、 enhance.setCheckboxVal /** * 设置表单元素禁用 * @param {String} type 类型，select、checkbox、radio * @param {String} name 对象名称，指“name” * @param {String} val 值，radio元素需要用到 * @returns {} */ 4、enhance.setElemDisabled /** * 表单填充 * @param {Object} data * @returns {} */ 5、 enhance.filling({ testSelect: 2 }); //表单填充 }); </script> 
var enhanceForm = layui.enhanceform; var enhance = new enhanceForm({ elem: '#userEditForm' //表单选择器 }); enhance.filling(jsonData);//其中jsonData为表单数据的json对象 文章来源: layui 表单增强插件
