330     // Validate the form manually
331     $(&#39;#validateBtn&#39;).click(function() {
332         $(&#39;#defaultForm&#39;).bootstrapValidator(&#39;validate&#39;);
333     });
334 
335     $(&#39;#resetBtn&#39;).click(function() {
336         $(&#39;#defaultForm&#39;).data(&#39;bootstrapValidator&#39;).resetForm(true);
337     });
338 });
339 </script>
340 </body>
341 </html>

看331行，点击提交时，用 

$(&#39;#defaultForm&#39;).bootstrapValidator(&#39;validate&#39;);　

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(&#39;bootstrapValidator&#39;);
   bootstrapValidator.validate();
   if(bootstrapValidator.isValid())
     $("#yourform").submit();
   else return;

});

酱紫就可以判断表单验证是否通过了。
