本文给大家介绍如何判断表单验证的实例代码，在没给大家介绍正文之前，先给大家介绍下插件。
插件介绍
先上一个图：
下载地址：https://github.com/nghuuphuoc/bootstrapvalidator
使用提示
中文化：
下载插件后，将\js\bootstrapValidator\language\zh_CN.js 引入文件，即实现中文化
提交前验证表单：

</body>
</html>
看331行，点击提交时，用
$('#defaultForm').bootstrapValidator('validate');
触发表单验证
下面是碰到的一个坑：
bootstrapValidator默认逻辑是当表单验证失败时，把按钮给变灰色。
但是项目中，button并不在form内部，是通过事件绑定来ajax提交的。那么问题来了：
项目需要当form验证失败时，不执行所绑定的后续事件。百度半天找不到相关资料，最后还是要靠google：
$("#yourform").submit(function(ev){ev.preventDefault();});
$("#submit").on("click", function(){
var bootstrapValidator = $("#yourform").data('bootstrapValidator');
bootstrapValidator.validate();
if(bootstrapValidator.isValid())
$("#yourform").submit();
else return;
});
