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="/UploadFiles/2021-04-02/layui.js">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>完整示例代码如下：
