js
面向对象

选择元素
this.ipt = $(".moe-search-input")[0];
this.search_close = $(".search-close")[0];
绑定事件
 $(this.ipt).on("focus", this.inputanimate.bind(this));
$(this.search_close).on("click", this.closeanimate.bind(this));

//搜索框聚焦动画
    Index.prototype.inputanimate = function () {
        $(this.topsearch).addClass(" active");
        $(this.search_box).addClass("active");
        $(this.body).addClass(" active");
        $(this.wrap).addClass(" active");
        $(".search-box input")[0].focus();
    }
    //关闭搜索框动画
    Index.prototype.closeanimate = function () {
        $(this.topsearch).removeClass(" active");
        $(this.search_box).removeClass("active");
        $(this.body).removeClass(" active");
        $(this.wrap).removeClass(" active");
    }
