问题描述

我有一个需要在IE8中检查的对象。
我尝试了开发人员工具和 console.log ,他们的Firebug等价物。
但是,当我将对象输出到日志时:

  console.log(元素:,元素) ; 
console.log(element);

我只收到字符串

 日志:元素:[object Object] 

而不是可点击的,可检查转储。



是否可以将对象转储到日志并检查其成员,如Firebug?



<我不能使用自制的dump()函数,因为我要检查的元素太大,浏览器会崩溃我。

解决方案

这是我发现有用的一种技巧:




  • 打开开发人员工具栏(点击F12)

  • 转到脚本标签

  • 点击开始调试 按钮

  • 接下来,在控制台中输入debugger并按Enter键。这应该会触发一个断点。

  • 转到观察子标签

  • 点击显示,点击添加..的行。并输入您要检查的变量。请注意,变量必须全局可用。

  • 此时您应该能够使用树状UI检查变量

  • 一旦你'重新调试单击继续按钮(或按F5)


I have an object I need to examine in IE8. I tried the developer tools and console.log, their Firebug equivalent. However, when I output the object to the log:

console.log("Element: ", element);
console.log(element);

I only get the string

LOG: Element: [object Object]

instead of a clickable, examinable dump.

Is it possible to dump an object to the Log and examine its members, like in Firebug?

I can't use a homemade dump() function because the element I want to examine is so huge the browser will crash on me.

解决方案

Here's one technique that I've found helpful:

  • Open the Developer Tool Bar (hit F12)
  • Go to the "Script" tab
  • Click the "Start Debugging" button
  • Next, type "debugger" into the console and hit enter. This should trigger a break point.
  • Go to the "Watch" sub-tab
  • Click the row that says, "Click to add..." and enter a variable you'd like to examine. Note that the variable must be globally available.
  • At this point you should be able to examine your variable with tree-like UI
  • Once you're done debugging click Continue button (or hit F5)
