使用Javascript：是的参数数组德precated？ [英] Javascript: is the arguments array deprecated?

问题描述

大多数网站说被调用者作为Function.arguments的属性是去precated。但是，一些网站进一步说，整个Functions.argument的是例如pcated德$ P $ <一href=\"http://aptana.com/reference/api/Arguments.html\">http://aptana.com/reference/api/Arguments.html为什么仅当整个程序在水中是死提被叫方？我刚刚发现论据，它似乎非常有用例如：<一href=\"http://hungred.com/how-to/secret-arguments-array-javascript/\">http://hungred.com/how-to/secret-arguments-array-javascript/

Most sites say "callee" as a property of Function.arguments is deprecated. But some sites go further and say the whole of Functions.argument is deprecated E.g. http://aptana.com/reference/api/Arguments.html Why only mention callee if the whole routine is dead in the water? I only just discovered "arguments" and it seems incredibly useful E.g: http://hungred.com/how-to/secret-arguments-array-javascript/

推荐答案

Function.arguments 的是的德precated，但它只是德$ p $赞成香草参数对象，在函数中可用的pcated。 （例如，使用 X =参数[I]; 而不是 X = theFunc.arguments [I]; ）

Function.arguments is deprecated, but it's only deprecated in favor of the vanilla arguments object that's available within a function. (e.g. using x = arguments[i]; instead of x = theFunc.arguments[i];)

这就是现在的preferred（正如你说的，是非常有用的）访问的序参数方法获得。

That's now the preferred (and as you say, extremely useful) method for accessing the ordinal arguments received.
