javascript - 我如何编写一个 onblur 函数来杀死这个 anchor 标记？

Question

我为 508 合规性编写了这段代码，但在用户关闭它后，我希望该元素能够正常运行，我该如何做到这一点？以下是:

handleInteraction:function(focusable){
    this.setElements();
    var totalAllowed = (this.elements.totalChar[0].innerHTML);
    var value = this.obj.value;
    var chars = value.length;
    var charsLeft = parseInt(totalAllowed) - parseInt(chars);
    if (charsLeft >= 0 || (typeof focusable=='boolean' && focusable==false)){
        this.elements.leftChar[0].innerHTML = charsLeft;
        this.elements.charLeftp.removeClass("error");           
    }
    else {
        this.obj.value = value.substring(0, totalAllowed);
        this.elements.leftChar[0].innerHTML = 0;
        this.elements.charLeftp.addClass("error")
        var divNA = dojo.byId("max-"+this.obj.id);
        if (divNA){
            dojo.destroy(divNA);    
        }
        divNA = dojo.create("a",{"id":"max-"+this.obj.id,"class":"hide-fromsighted","innerHTML":"<h5>This textarea has reached the maximum allowed number of characters. Please navigate backwards!</h5>","tabindex":"-1"});
        dojo.place(divNA,this.obj,'after');
        divNA.focus();


        /*
         * Here apply the onblur event to kill the <a>
         */
    }

我假设您正在使用 Dojo 工具包。你可以销毁 <a>用 dojo.destroy 标记，你可以使用 dojo.stopEvent 来停止 <a>事件传播。
