本文实例讲述了layui.js实现的表单验证功能。分享给大家供大家参考，具体如下：

该示例可针对文本框，手机，邮箱，textarea等格式进行验证

首先引入如下文件：

<script src="layui/layui.js"></script>
<script src="layui/lay/dest/layui.all.js"></script>
<link rel="stylesheet" href="layui/css/layui.css" rel="external nofollow" rel="external nofollow" >

html代码：

<form class="layui-form" action="">
 <div class="layui-form-item">
  <label class="layui-form-label">反馈主题</label>
  <div class="layui-input-block">
   <input name="title" class="layui-input" type="text" placeholder="请输入标题" autocomplete="off" lay-verify="title">
  </div>
 </div>
 <div class="layui-form-item">
  <label class="layui-form-label">姓名</label>
  <div class="layui-input-block">
   <input name="fname" class="layui-input" type="text" placeholder="请输入姓名" autocomplete="off" lay-verify="fname">
  </div>
 </div>
 <div class="layui-form-item">
  <label class="layui-form-label">手机</label>
  <div class="layui-input-block">
   <input name="phone" class="layui-input" type="tel" autocomplete="off" placeholder="请输入手机" lay-verify="phone">
  </div>
 </div>
 <div class="layui-form-item">
  <label class="layui-form-label">邮箱</label>
  <div class="layui-input-block">
   <input name="email" class="layui-input" type="text" autocomplete="off" placeholder="请输入邮箱" lay-verify="email">
  </div>
 </div>
 <div class="layui-form-item">
  <label class="layui-form-label">单选框</label>
  <div class="layui-input-block">
   <input name="sex" title="男" type="radio" checked="" value="男">
   <input name="sex" title="女" type="radio" value="女">
   <input name="sex" title="保密" type="radio" value="密">
  </div>
 </div>
 <!--<div class="layui-form-item layui-form-text">
  <label class="layui-form-label">普通文本域</label>
  <div class="layui-input-block">
   <textarea class="layui-textarea" placeholder="请输入内容">请输入内容</textarea>
  </div>
 </div>-->
 <div class="layui-form-item layui-form-text">
  <label class="layui-form-label">内容</label>
  <div class="layui-input-block">
   <textarea class="layui-textarea layui-hide" name="contact" id="lay_demo_editor" lay-verify="contact"></textarea>
  </div>
 </div>
 <div class="layui-form-item">
  <div class="layui-input-block">
   <button class="layui-btn" lay-filter="demo2" lay-submit="">跳转式提交</button>
   <button class="layui-btn" lay-filter="demo1" lay-submit="">立即提交</button>
   <button class="layui-btn layui-btn-primary" type="reset">重置</button>
  </div>
 </div>
</form>

js验证代码

<script>
layui.use(['form', 'layedit', 'laydate'], function(){
 var form = layui.form()
 ,layer = layui.layer
 ,layedit = layui.layedit
 ,laydate = layui.laydate;
 //自定义验证规则
 form.verify({
    title: function(value){
     if(value.length < 5){
      return '标题至少得5个字符啊';
     }
    }, fname: function(value){
     if(value.length < 4){
      return '请输入至少4位的用户名';
     }
    }, contact: function(value){
     if(value.length < 4){
      return '内容请输入至少4个字符';
     }
    }
    ,phone: [/^1[3|4|5|7|8]\d{9}$/, '手机必须11位，只能是数字！']
    ,email: [/^[a-z0-9._%-]+@([a-z0-9-]+\.)+[a-z]{2,4}$|^1[3|4|5|7|8]\d{9}$/, '邮箱格式不对']
 });
 //创建一个编辑器
 layedit.build('lay_demo_editor');
 //监听提交
 form.on('submit(demo1)', function(data){
  layer.alert(json.stringify(data.field), {
   title: '最终的提交信息'
  })
  return false;
 });
});
</script>
