jquery怎么移除不了事件呢？

Question

 function RecommandProduct(obj, id) {
            setRecommand(obj, id, 1, true);
        }        function UnRecommandProduct(obj, id) {
            setRecommand(obj, id, 0, false);
        }        function setRecommand(obj, id, state, up) {
            var _this = $(obj);
            var recommandCountVal = parseInt(recommandCount.html());
            if(!up||(recommandCountVal+1)<=MaxRecommend)
            {
               $.ajax({
                    type: "POST",
                    dataType: "json",
                    url: "/Manage/Mall/setRecommand.aspx",
                    data: { state: state, productId: id, __RequestVerificationToken: $("[name='__RequestVerificationToken']").val() },
                    success: function(data) {
                        if (data.state == 1) {
                           $("#" + id + "").attr("recommand", state);
                            if(up)
                            {
                                recommandCount.html(recommandCountVal+1);  
                              _this.css('color',"red").html("取消橱窗推荐").unbind( "click" ).bind("click",function(e){  UnRecommandProduct(e.target,id); });
                            }
                            else
                            {
                                recommandCount.html(recommandCountVal-1);                            
                               _this.css("color","#0000FF").html("设为橱窗推荐").unbind( "click" ).bind("click",function(e){  RecommandProduct(e.target,id); });
                            }
                        }
                        else if (data.state == 3)
                            alert("最多只能推荐50个圣品");
                        else
                            alert('对不起，系统繁忙，请稍候再尝试');
                    }
                });   
            }
            else
            {
                if(up)
                    alert('最多只能推荐'+MaxRecommend+'个圣品');
            }
        }
//下面是元素
 <a style="color:red" onclick='UnRecommandProduct(this,<%=ele.ProductId %>)'                        href='javascript:void(0);'>取消橱窗推荐</a>
<a style="color: #0000FF" onclick='RecommandProduct(this,<%=ele.ProductId %>)' href='javascript:void(0);'>
                            设为橱窗推荐</a>一开始我就设定了初始值，我想每次点击之后都变换一下他的 click 函数。。
请高手赐教

Answer 1

我生气了，决定把整个元素移除掉
换成这样function setRecommand(obj, id, state, up) {
            var _this = $(obj);
            var recommandCountVal = parseInt(recommandCount.html());
            if(!up||(recommandCountVal+1)<=MaxRecommend)
            {
               $.ajax({
                    type: "POST",
                    dataType: "json",
                    url: "/Manage/Mall/setRecommand.aspx",
                    data: { state: state, productId: id, __RequestVerificationToken: $("[name='__RequestVerificationToken']").val() },
                    success: function(data) {
                        if (data.state == 1) {
                           $("#" + id + "").attr("recommand", state);
                            if(up)
                            {
                               recommandCount.html(recommandCountVal+1);  
                                _this.after("<a style='color:red' onclick='UnRecommandProduct(this,"+id+")' href='javascript:void(0);'>取消橱窗推荐</a>").remove();
                            }
                            else
                            {
                               recommandCount.html(recommandCountVal-1);                            
                                _this.after("<a style='color:#0000FF' onclick='RecommandProduct(this,"+id+")' href='javascript:void(0);'>设为橱窗推荐</a>").remove();
                            }
                        }
                        else if (data.state == 3)
                            alert("最多只能推荐50个圣品");
                        else
                            alert('对不起，系统繁忙，请稍候再尝试');
                    }
                });   
            }
            else
            {
                if(up)
                    alert('最多只能推荐'+MaxRecommend+'个圣品');
            }
        }

Answer 2

变换一下他的 click 函数 代表什么意思?

Answer 3

从他的RecommandProduct 变为 UnRecommandProduct
意思是，原来 要移除原来的事件函数，再绑定另外的函数

Answer 4

从他的RecommandProduct 变为 UnRecommandProduct
意思是，移除原来的事件函数，再绑定另外的函数

Answer 5

$('div').bind('click', RecommandProduct);//为div绑定RecommandProduct 函数
$('div').unbind('click', RecommandProduct);//取消RecommandProduct 函数
$('div').bind('click', UnRecommandProduct);//为div绑定UnRecommandProduct函数

Answer 6

谢谢 5 楼的，但是我一开始 就像你说那样操作，下面是代码
 _this.css('color',"red").html("取消橱窗推荐").unbind( "click" ).bind("click",function(e){  UnRecommandProduct(e.target,id); });
我原来就是这个样子的。
但是我一开始 显示的时候 就已经将函数写到标签里去，而没用bind（）
<a style="color: #0000FF" onclick='RecommandProduct(this,<%=ele.ProductId %>)' href='javascript:void(0);'>设为橱窗推荐</a>

Answer 7

<a style="color: #0000FF" onclick='RecommandProduct(this,<%=ele.ProductId %>)' href='javascript:void(0);'>设为橱窗推荐</a>
不要用代码绑定，用jquery的函数
如果是代码绑定的，就用$("a").removeAttr("onclick").attr("onclick", "UnRecommandProduct(this,<%=ele.ProductId %>)");

Answer 8

呵呵。。我就知道要这样做的啦。
虽然没经过测试，但是是可以的。
谢谢啦，是不是用代码绑定 是不能用 unbind 的？

Answer 9

unbind 是取消绑定
$('div').bind('click', RecommandProduct);//为div绑定RecommandProduct 函数
$('div').unbind('click', RecommandProduct);//取消RecommandProduct 函数

Answer 10

写到标签里面，被视为属性，要用removeAttr
