使用本地主机测试Ajax [英] Testing Ajax using localhost

问题描述

我正在尝试使用Javascript测试一个简单的Ajax脚本，但没有收到响应.PHP脚本放置在本地服务器的 htdocs 文件夹中，而包含Ajax调用的HTML页面放置在我的桌面上.从服务器收到的 readyState 为4，但返回的状态为0，而不是200.

I am trying to test a simple Ajax script using Javascript and I'm not receiving a response. The PHP script is placed in the htdocs folder of the local server and the HTML page that includes the Ajax calls is placed on my desktop. A readyState of 4 is received from the server but the status returned is 0, not 200.

在Firefox状态下生成的错误:

The error generated on Firefox state:

NS_ERROR_DOM_BAD_URI:拒绝访问受限制的URI.

这是负责调用Ajax对象的代码部分:

Here is the section of code responsible for calling the Ajax object:

var myRequest = getXMLHttpRequest();

function callAjax() {
    var url = "localhost/clock.php";
    var myRandom = parseInt(Math.random()*99999999);
    myRequest. open("GET", url + "?rand=" + myRandom, true);
    myRequest.onreadystatechange = responseAjax;
    myRequest.send(null);
}

function responseAjax() {
    if(myRequest.readyState == 4) {
        if(myRequest.status == 200) {
            var now = new Date();
            var localTime = now.getHours() + ":" + now.getMinutes() + ":" + now.getSeconds();
            var serverTime = myRequest.responseText;
            document.getElementById("clock").innerHTML = "Server: " + serverTime + "<br />Local: " + localTime;
        } else {
            alert("An error has occurred: " + myRequest.statusText);
        }
    }
}

任何人都可以洞悉我的问题吗?

推荐答案

您说您的文件在桌面上.您无法打开本地文件(file://)并执行ajax.您需要通过Apache服务器(http://)访问该文件.

You say your file is on the desktop. You cannot open a local file ( file:// ) and do ajax. You need to access the file through your Apache server ( http:// ).
