给代码添加如下部分:
layui.use('form', function(){ //此段代码必不可少
var form = layui.form;
form.render();
});
实现效果:
HTML代码:
<div class="layui-form-item">
<label class="layui-form-label">执行周期</label>
<div class="layui-input-inline" style="width: 90px;">
<select name="period_type" lay-verify="required" lay-filter="period">
