问题描述
<！DOCTYPE html>
< html>
< head>
< script src =jquery-2.1.4.js>< / script>
< script>
$（document）.ready（function（）{
$（button）。click（function（）{
$（＃div1）。load（rao.txt ）;
}）;
}）;
< / script>
< / head>
< body>
< div id =div1>< h2>让jQuery AJAX更改此文本< / h2>< / div>
< button>获取外部内容< / button>
< / body>
< / html>
我想用一些文本或其他网页更改div1的内容，而无需重新加载默认页面。
在控制台中收到以下错误消息：
$ b
XMLHttpRequest无法加载文件：/// C：/Users/hamma/Desktop/rao.html。交叉原始请求仅支持协议模式：http，data，chrome，chrome-extension，https，chrome-extension-resource。
根据您的控制台输出：
XMLHttpRequest无法加载file：/// C：/用户/汉玛/桌面/ rao.html。只有协议方案支持跨源请求：http，data，chrome，chrome-extension，https，chrome-extension-resource。
这意味着你正试图运行没有服务器的文件，例如 file：/// [...] ，出于安全原因，你不能运行AJAX请求
您需要设置服务器并通过该页面运行该页面以发送请求。

<script src="jquery-2.1.4.js"></script>
<script>
$(document).ready(function(){
$("button").click(function(){
$("#div1").load("rao.txt");
});

<body>
<div id="div1"><h2>Let jQuery AJAX Change This Text</h2></div>
<button>Get External Content</button>
</body>
</html>
i want to change the content of div1 with some text or some other webpage without reloading the default page.
I get the following error message in the console:
XMLHttpRequest cannot load file:///C:/Users/hamma/Desktop/rao.html. Cross origin requests are only supported for protocol schemes: http, data, chrome, chrome-extension, https, chrome-extension-resource.
According to your console output:
XMLHttpRequest cannot load file:///C:/Users/hamma/Desktop/rao.html. Cross origin requests are only supported for protocol schemes: http, data, chrome, chrome-extension, https, chrome-extension-resource.
That means that you are trying to run the file without a server i.e. file:///[...] and for security reasons you can't run AJAX requests like that.
You need to setup a server and run the page through that to send requests.
