I need to pass an array as built-in function. For example this works fine:
我需要传递一个数组作为内置函数。例如,这工作正常:
console.info('%cBlue text%c Red text', 'color:blue', 'color:red');
There are 3 parameters, but what should I do when I got n parameter?
有3个参数,但是当我得到n参数时该怎么办?
var x = [ '%cBlue text%c Red text...%c nth-Text', 'color:blue', 'color:red', ... , 'nth-color:black'];
console.info.apply(null, x);
does not work. Thanks in advance.
不起作用。提前致谢。

It fails because you pass null as context instead of the console object. This works :
它失败是因为您将null作为上下文而不是控制台对象传递。这有效:
console.info.apply(console, x);
More generally, you can use apply for your own functions too, but when they need a context, you must set it.
更一般地说,您也可以使用apply来处理自己的函数,但是当它们需要上下文时,您必须设置它。
