如何从javascript请求json文件
我有一个url，它返回一个json文件（我在地址栏中输入了url并显示了json输出）但我不知道如何在javascript中请求json文件。有谁能够帮我？
这是代码：
var url = 'http://www.worldweatheronline.com/feed/weather.ashx?q=kalutara&format=json&num_of_days=4&key=myKey' ;
if (window.XMLHttpRequest) {
http_request = new XMLHttpRequest();
} else if (window.ActiveXObject) {
http_request = new ActiveXObject("Microsoft.XMLHTTP");
}
http_request.open('GET', url, true);
http_request.send(null);
http_request.onreadystatechange = function() {
if ( http_request.readyState == 4) {
if ( http_request.status == 200)
success( http_request.responseText);alert(http_request.responseText);
else if (failure)
failure( http_request.status, http_request.statusText);
}
};
