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;
});
