Bind Point to control
原标题:Bind click to control
count=1;
for(var i=0;i<5;i++){
   count++;
   $("#ImageProductLeft"+count.toString()).bind( click , function(){
           alert(i);                                                                                                                                    
   });
}

我想,在点击<条码>时。 ∗∗∗∗∗∗∗∗∗∗

onclick on all ImageProductLeft1 :alert(5)

最佳回答
count=1;
for(var i=0;i<5;i++){
   count++;
   $("#ImageProductLeft"+count.toString()).bind( click , {i: i}, function(event){
         alert(event.data.i);
   });
}
问题回答

这比以往更有利,更灵活:

$("div[id^= ImageProductLeft ]").each(function(index) {
    $(this).click(function() {
        alert(index);
    });
});

你可以像你所希望的那样,拥有从<代码>开始的同样内容,并点击任何内容,提醒他们各自的指数。

现场测试案例

for (var i = 1; i<6; i++)
{
    $("#ImageProductLeft" + i.toString()).bind( click , function() {
        alert(i);
    });
}

You re having this problem because the i in each of the event handlers you created is pointing to the same location in memory. Try using this:

count=1;
for(var i=0;i<5;i++){
   count++;

   $("#ImageProductLeft"+count.toString()).bind( click , 
       function(x){
           return function() { alert(x); };
       }(i)                                                                                                                                    
   });
}

这是一个相当常见的错误。 See ,this for further interpret
