如何调试Javascript应用程序? [英] How do you debug Javascript applications?
问题描述
对于JavaScript,大多数浏览器中的调试是一个阴性:
IE - 您真正需要调试的地方, F12 是控制台。您可以调用 console.log
, console.debug
, console.error
等等,它会打印出好的数据。当您在对象上调用 console.log
时,好的控制台将打印出对象的属性分解。还有一个主动的dom检查器,以便您可以看到脚本正在运行时发生了什么。
- Firefox - 获取 Firebug插件。这是我最喜欢的控制台。我曾经梦想过的一切都需要,还有一些功能。
- Chrome - 内置控制台,检查页面上的元素,以查看DOM的细分。 li>
- Opera - 内置控制台
- Safari -
添加 Firebug Lite 到页面,您将有一个JS驱动版本的Firebug。Safari具有类似于Chrome的内置开发工具,但他们需要启用。
对于所有浏览器,您可以添加 Firebug Lite ,但是我真的只用于IE和Safari。
I work in an application that is JavaScript intense. So to debug , I end up using many alerts. Are there other better ways to debug ? What methods do you use ?
For JavaScript, debugging is a sinch in most browsers:
IE - Where you really need to debug, F12 is the console. You can call console.log
, console.debug
, console.error
and a few others, and it will print out good data. When you call console.log
on an object, good consoles will print out the property break-down of the object. There's also an active dom inspector so that you can see what's going on as the script is running.
- Firefox - Get the Firebug addon. It is my favorite console of them all. Does everything I've ever dreamed of needing, and a few more features.
- Chrome - Built-in console, inspect element on the page to see the breakdown of the DOM live.
- Opera - Built-in console
- Safari -
Add Firebug Lite to the page, and you'll have a JS driven version of Firebug.Safari has built-in dev tools similar to Chrome, however they need to be enabled.
For all browsers, you can add Firebug Lite, but I really only use it for IE and Safari.
