js代碼保護-混淆js代碼

可以使用加密工具 VirboxProtector 對js代碼做加密保護。

最近嘗試了一個加強廠商（VirboxProtector ）的js代碼保護，加密前後效果很明顯。

加密前js代碼：

/* 标簽切換 */
    /*
        tabclass  ： 标簽切換的總容器的class
        tab_title ： 标簽容器的class
        tab_body  ： 标簽内容容器的class
        tab_list  ： 标簽實體的class
    */

function myTab(tabclass){
    var tab_title = $(tabclass).find(".tab-title");
    var tab_body = $(tabclass).find(".tab-body");
    var tab_listIndex = 0;
    var _this = this;
    _this.tabclass = tabclass;
    tab_title.find(".tab-btn").hover(function(){
        tab_listIndex =$(this).index();
        $(this).addClass("active").siblings().removeClass("active");
        tab_body.find(".tab-list").eq(tab_listIndex).show().siblings().hide();
    });
}
$(function(){
    //tab切換
    myTab(".tab-index-product");
    myTab(".tab-index-intro");
    myTab(".tab-advantage");

    // 頁面動畫
    new WOW().init();
})      

加密後的效果：
