1、定義下拉框

<div class="layui-input-block  layui-form" lay-filter="selFilter">
     <select id="sel" lay-verify="required" >
            <option value="">請選擇</option>
             <option value="A">選項A</option>
             <option value="B">選項B</option>
     </select>
   </div>
 

• 1
• 2
• 3
• 4
• 5
• 6
• 7

2、設置默認值：$(“#sel”).val(“B”);
3、渲染：form.render(‘select’,’selFilter’);
註：局部刷新需要使用lay-filter，並且設置class=”layui-form”

1. var category = 0;
2. var categoryName = ‘‘;
3. form.on(‘select(

   selFilter

   )‘, function (data) {
4. category = data.value;
5. categoryName = data.elem[data.elem.selectedIndex].text;
6. form.render(‘select‘);
7. });
