本文給大家介紹如何判斷表單驗證的實例代碼，在沒給大家介紹正文之前，先給大家介紹下插件。
插件介紹
先上一個圖：
下載地址：https://github.com/nghuuphuoc/bootstrapvalidator
使用提示
中文化：
下載插件後，將/js/bootstrapValidator/language/zh_CN.js 引入文件，即實現中文化
提交前驗證表單：
更豐富一點的表單驗證例子：http://www.jq22.com/yanshi522，直接上代碼：

$('#defaultForm').bootstrapValidator('validate');觸發表單驗證
下面是碰到的一個坑：
bootstrapValidator默認邏輯是當表單驗證失敗時，把按鈕給變灰色。
但是項目中，button並不在form內部，是通過事件綁定來ajax提交的。那麼問題來了：
項目需要當form驗證失敗時，不執行所綁定的後續事件。百度半天找不到相關資料，最後還是要靠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;});以上所述是小編給大家介紹的Bootstrap中的表單驗證插件bootstrapValidator使用方法整理（推薦）的相關知識，希望對大家有所幫助，如果大家有任何疑問請給我留言，小編會及時回復大家的。在此也非常感謝大家對武林網網站的支持！
