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>
