触发校验用：
$('表单元素form').bootstrapValidator('validate');
常见问题：
1.插件自带的一个功能，点击校验按钮，校验失败按钮被禁止，校验成功才解开禁止
2.提交按钮不在form表单中，通过事件绑定进行ajax数据提交，当表单验证失败时不执行所绑定的后续事件，怎么解决？
解决方案如下：
$("表单").submit(function(ev){ev.preventDefault();});
$("表单外的按钮元素").on("click", function(){
// 触发校验获取校验结果
var bootstrapValidator = $("表单").data('bootstrapValidator');
bootstrapValidator.validate();
// 判断是否校验成功
if(bootstrapValidator.isValid())
// 校验成功调用submit触发表单提交
$("你的表单元素").submit();
//如果校验不成功就直接返回，不触发按钮
else return;
});
