将阵列变成单独的论点
原标题:Convert an array into a separate argument strings

我将如何把这一阵列作为履行这一职能的一系列手段? 这部法典没有工作,但我认为它说明了我试图做些什么。

var strings = [ one , two , three ];

someFunction(strings.join(" , ")); // someFunction( one , two , three );

感谢!

解决办法非常简单, Java文中的每一功能都有一种与其相关的方法,即“适用”,即认为你希望作为阵列通过的论点。

因此:

var strings = ["one", "two", "three"];
someFunction.apply(this, strings);

此处的意思是,如果其只是一个没有物体的页上的功能,那么该页的范围就会被否定,否则就会使你在要求时所希望的方法的范围消失。

反过来,在有些职能范围内,你将写一下你的法典:

function someFunction() {
  var args = arguments; // the stuff that was passed in
  for(var i = 0; i < args; ++i) {
    var argument = args[i];
  }
}
