如何区分多个Titanium.Network.createHTTPClient()return

Question

我在 for 循环中发送多个 Titanium.Network.createHTTPClient()。

当我处理 return 文本时，我无法理解每个 send() 对应的响应。

如何区分多个 createHTTPClient() return 对象？？

url[0] = http://api.yahoo.com?key=0
url[1] = http://api.yahoo.com?key=1
url[2] = http://api.yahoo.com?key=2

var xhrArray = new Array();

for (var k = 0 ; k < 3;k++){
    var v = encodeURIComponent(url[k]);
    xhrArray[k] = Titanium.Network.createHTTPClient();
    xhrArray[k].autoEncodeUrl = false;
    xhrArray[k].onload = function(e){

        var response = JSON.parse(xhrArray[k].responseText);            
         //It doesnt work, How can I distinguish multiple xhr return??

    };
    xhrArray[k].open('GET', url[k], true);
    xhrArray[k].send();
}

将自定义属性分配给 HTTPClient 实例

xhrArray[k].myProperty = 'Hello';

从 this 中捕获它，例如：this.myProperty

完整示例：

var url = [
        'http://api.yahoo.com?key=0',
        'http://api.yahoo.com?key=1',
        'http://api.yahoo.com?key=2'
    ],
    xhrArray = [];

for (var k = 0; k < 3; k++) {

    //var v = encodeURIComponent(url[k]);
    xhrArray[k] = Titanium.Network.createHTTPClient();
    xhrArray[k].autoEncodeUrl = false;

    // Assign your custom property
    xhrArray[k].myProperty = k;
    xhrArray[k].onerror = function(e) {

        var response = JSON.parse(xhrArray[this.myProperty].responseText);

    };
    xhrArray[k].open('GET', url[k], true);
    xhrArray[k].send();
}
