javascript - 使用数组值作为数组名称

Question

我试图将数组值作为参数传递到函数中，然后使用它的值来引用另一个数组。我知道这听起来有点复杂，但我这样做是有原因的；)我认为 showProject 认为 project1 是一个字符串，因为它只返回“p”并且......有任何帮助吗？

var projects = ["project1","project2"];

var project1 = ["image1","image2"];
var project2 = ["image1","image2"];

function showProject(arr){

    console.log(arr[0]);

}

//why isn't this showing image 1 in project 1 array?
showProject(projects[0]);

Answer 1

这似乎就是你想要的:

jsFiddle

var project1 = ["image1","image2"];
var project2 = ["image1","image2"];

var projects = [project1,project2];

function showProject(arr){

    alert(arr[0]);

}

showProject(projects[0]);

将数组设置为 projects 数组的元素。
