	form 表单添加  layui-form-pane 的class，来设定表单的方框风格
	-->
	<form class="layui-form" action="">
  <div class="layui-form-item">
    <label class="layui-form-label">单行输入框</label><!--文本-->
    <div class="layui-input-block">
        <input type="text" name="title" lay-verify="title" autocomplete="off" placeholder="请输入标题" class="layui-input">
	
	
      	<!--placeholder属性：让输入框有个提示的显示。-->
        <!--lay-verify属性：注册form模块需要验证的类型-->
        <!--autocomplete="off"属性 -->
        <!--
        当我们在浏览器中输入表单信息的时候，
        往往input文本输入框会记录下之前提交表单的信息，
        以后每次只要双击 input文本输入框就会出现之前输入的文本，
        这样有时会觉得比较方便，但有时也会暴露用户的隐藏数据， 所以   
        autocomplete="off"属性   
        是为了让input表单输入框不记录输入过信息的方法
