原标题:How to overcome the http request status zero in a local machine

有许多同样的问题,但我无法找到答案,这样一来,这个问题就会再次出现。 我收到了使用java书写器的json申请。

    var request = null;
    if (window.XMLHttpRequest) {
        request = new XMLHttpRequest();
    } else if (window.ActiveXObject) {
        request = new ActiveXObject("Microsoft.XMLHTTP");
    } else {
        return null;
    }
    request.open("GET", url, true);
    request.send(null);

    request.onreadystatechange = function() {
        if (request.readyState == 4) {
            if (request.status == 200) {
}
} else
                alert(request.status);
        }

I am receiving an status code zero while i receive the request the javascript runs on apache server and json request will be received from tomcat server everything is local . can any one tell me how to over come it. Note: i cannot use any framework.
