What is the source code for the default alert() function in Javascript(method of the window object)? I am trying to write an alert function myself so I would really like to get a peek at the original function code.It is so hard to google it.
推荐答案
alert()
函数与许多其他标准函数一样,是浏览器Javascript运行时的一部分。它无法使用Javascript代码复制(除了通过调用 alert()
),并且该函数没有与平台无关的Javascript源代码。
The alert()
function, like a number of other standard functions, is a part of the browser's Javascript runtime. It cannot be replicated with Javascript code (other than by calling alert()
), and there is no platform-independent Javascript source code to the function.
