我有一个值数组：
['a'，'b'，'c'，'d' ]我需要将这些参数作为参数传递给函数：
window.myFunction（'a'，'b'，'c'，'d'）;如果我只能将数组/对象传入函数，这会更容易，但函数由其他人编写或已经存在，我不能改变它们 - 它们需要作为单独的参数传递，这就是我需要解决的。
传递的值的数量不一致。它可能是一个，它可能是100.
同样，我不能影响功能。他们是怎么样的，我总是会收到一系列的价值观传入他们。
使用 函数对象的 .apply 方法。 window.myFunction。 apply（window，['a'，'b'，'c'，'d']）;.apply 方法调用函数you你可以设置函数的这个值（第一个参数），并且可以使用Array（第二个参数）设置它的参数。
所以我们在这里保存 window 作为 this 的值，我们传递数组作为单独的参数。 Array成员将被分发，就像它们作为单独的参数传递一样，所以就好像你已经做了这样的事情：
窗口。 myFunction的（ 'A'， 'b'， 'C'， 'd'）;
I have an array of values:
['a', 'b', 'c', 'd']and I need to pass these as parameters to a function:
window.myFunction('a', 'b', 'c', 'd');This would be easier if I could just pass the array/object into the function, but the functions are written by other people or already exist and I cannot change them - they need to be passed as individual parameters, which is what I need solved.
The number of values being passed is not consistent. It may be one, it may be 100.
Again, I cannot affect the functions. They are how they are, and I will always receive an array of values to pass into them.
解决方案Use the .apply method of the Function object.
window.myFunction.apply(window, ['a','b','c','d']);The .apply method invokes the function you're calling, but lets you set the function's this value (the first argument) and lets you set its arguments using an Array (the second argument).
So here we kept window as the this value, and we're passing the Array as the individual arguments. The Array members will be distributed as though they were passed as individual arguments, so it's as if you had done this:
window.myFunction('a','b','c','d');
