[英]In JS, how can I use a string to define a JS object parameter?
I have a function defined that way: 我有这样定义的函数:
var myObject = new Object();
function myFunction(someString){
myObject.someString= 0;
}
The problem is someString
is taken as the string someString
instead of the value of that variable. 问题是
someString
被当作字符串someString
而不是该变量的值。
So, after I use that function several times over with different someString
's, I would like to get an object with all the values for each someString. 因此,在对不同的
someString
多次使用该函数之后,我想获得一个包含每个someString的所有值的对象。
But when I loop through that object The only result I get is someString : 0
但是当我遍历该对象时,我得到的唯一结果是
someString : 0
I want to get: 我想得到:
John : 0
James : 0
Alex : 0 etc....
How do I do that? 我怎么做? Thanks a lot in advance
提前谢谢
You can use the associative array approach: 您可以使用关联数组方法:
var someString = 'asdf';
myObject[someString] = 0; // {asdf: 0}
myObject['foo'] = 'bar';
You can basically use any string to retrieve your method/parameter. 您基本上可以使用任何字符串来检索您的方法/参数。
var i = 1;
myObject['test' + i] = i + 1; // gives us {test1: 2}
Try this 尝试这个
var myObject = new Object();
function myFunction(someString){
myObject[someString]= 0;
}
