Window.console property returns a reference to the 控制台 object, which provides methods for logging information to the browser's console. These methods are intended for debugging purposes only and should not be relied on for presenting information to end users.

范例

日志到控制台

第一个范例日志文本到控制台。

console.log("An error occurred while loading the content");
					

下一个范例把对象日志到控制台，采用对象的字段可扩展使用披露 Widget:

console.dir(someObject);
					

见 用法 in console 更彻底了解范例。

控制台 API	实时标准	初始定义。

Currently there are many implementation differences among browsers, but work is being done to bring them together and make them more consistent with one another.
