在警告框中转储jquery对象-dumpjqueryobjectinanalertbox

I am not quite adept in maneuvering jQuery, and it came to a point that I need to debug a program that was passed down from me without a documentation.

我不太擅长操纵jQuery，而且我需要调试一个在没有文档的情况下传递给我的程序。

I have this var a, an object, that I really want to know the content of its collection. In my mind I need a function like foreach() in PHP to iterate over this object variable. Upon researching I end up in using jQuery.each(). Now I can clearly iterate and see what was inside var a.

我有这个var a，一个对象，我真的想知道它的集合的内容。在我看来，我需要像PHP中的foreach（）这样的函数迭代这个对象变量。经过研究，我最终使用了jQuery.each（）。现在我可以清楚地迭代并查看var内部的内容。

However, it was kind of annoying to alert once every value on the var a. What I wanna know if it's possible to display all the contents in just one pop of alert box?

但是，对var a上的每个值进行一次警报有点烦人。我想知道是否可以在一个警报框中显示所有内容？

Here is my code:

这是我的代码：

$.each(a, function(index, value) { 
alert(index + ': ' + value); 
});

The var a contains infos such as:

var a包含以下信息：

creationdate: date_here
id: SWFUpload
modificationdate: date_here
type: .jpg
index: 0
name: uploaded_filename.jpg
size: size_in_bytes

BTW: The var a is called via file upload script.

BTW：var a通过文件上传脚本调用。

2 个解决方案

var acc = []
$.each(a, function(index, value) {
    acc.push(index + ': ' + value);
});
alert(JSON.stringify(acc));

alert(yourObject.toSource());
