将JS变量名传递给函数 [英] Passing JS variable name to function

问题描述

这就是我想要做的:

1. 设置了名为data_1的变量.

var data_1 = {
  "y_legend": {
    "text": "# of Patients",
    "style": "{font-size: 20px; color: #778877}"
  },
  "x_legend": {
    "text": "AUG 09 - OCT 09",
    "style": "{font-size: 20px; color: #778877}"
  }
};

在下拉菜单中，用户选择值为data_1的调用load('data_1')的选项.

In a drop down a user selects an option with the value of data_1 that calls load('data_1').

function load(data)
{
  tmp = findSWF("my_chart");
  x = tmp.load( JSON.stringify(data) );
}

我的问题:我正在选择一个值为data_1的选项，而不是变量本身. 因此，在函数load('data_1')中，当我alert(data)时，我得到data = 'data_1'.

My Problem: I'm selecting an option with the value data_1 and not the variable itself. So in my function load('data_1'), when I alert(data) I get data = 'data_1'.

那么如何通过仅传递字符串名称来获取加载函数中变量data_1的内容?

So how do I get the contents of my variable data_1 in my load function by passing only the name of the string?

推荐答案

var data_1 = { /* data goes here */ };

var data_choices = {1: data_1, 2: data_2, /* and so on */};

var load = function (data) {
    // data is "1", "2", etc. If you want to use the full data_1 name, change
    // the data_choices object keys.

    var tmp = findSWF("my_chart");
    var x = tmp.load( JSON.stringify(data_choices[data]) );
}
