使用带有for循环的jquery定义单击事件 [英] Defining click events using jquery with for loop

问题描述

以下是代码：

Here's the code:

Popups = [{c:'#Payment-Selection',w:'#Cards-Popup'},{c:'#Drop-SY',w:'#Start-Years'}];
var ActivatePopups = function() {
    for (var i=0; i<Popups.length; i++) {
        $(Popups[i]['c']).click(function() { PopupDrop(Popups[i]['w']); });
    }
}
ActivatePopups();

实际Popups数组要长得多，这就是为什么我要使用这种方法。无论如何，这不起作用，因为当我定义函数粗体函数时会出现问题。



触发点击，但似乎触发功能未完成，因为我收到了这样的错误 - ：

'未捕获的TypeError：无法读取未定义的属性'w''

Actual Popups array is much longer, thats why I want to use such method. Anyway, this does not work because there is problem when I define function bolded function.

The click is triggered, but it seems, that the firing function is not complete, because I'm getting such error¬:
'Uncaught TypeError: Cannot read property 'w' of undefined'

推荐答案

（弹出窗口[ i] [' c']）。click（function（）{PopupDrop（Popups [i] [ ' w']）;}）;
}
}
ActivatePopups（）;

(Popups[i]['c']).click(function() { PopupDrop(Popups[i]['w']); }); } } ActivatePopups();

如果没有你的内容很难说出错了什么代码 PopupDrop ;但是让我们用更精细的细节来写它。也许你打算做一些不同的事情。让我们看看：

It hard to say what's wrong without having your code for PopupDrop; but let's write it in finer detail. Maybe you meant to do something different. Let's see:

var ActivatePopups = function() {
    for (var i=0; i<popups.length;>
        cElement =

（Popups [i] .c）; // id选择器找到的元素的jQuery包装器
// 另外，请注意使用索引'c'和'w'的更好语法
wElement =

(Popups[i].c); // jQuery wrapper for the element found by the id selector // also, pay attention for better syntax for using indices 'c' and 'w' wElement =
