jQuery不断在我的CDN脚本中放入缓存破坏符? [英] jQuery keeps putting a cache buster in my CDN scripts?

问题描述

我有一个脚本，该脚本使用$.get( ... )从服务器中提取一段HTML，并使用$.html将其呈现在<div>中.有时，在拉出的HTML中有<script>标记，我注意到jQuery在对这些脚本的请求中放入了缓存破坏符参数，这导致浏览器再次请求已加载的脚本.

I have a script that uses $.get( ... ) to pull a piece of HTML from my server, and render it inside a <div> with $.html. Sometimes I have <script> tags in the pulled HTML, and I noticed that jQuery is putting a cache buster parameter in the request for these scripts and it's causing the browser to request again for scripts that have already been loaded.

例如:

有什么主意我可以禁用此行为吗?

Any idea how I can disable this behavior?

脚本标签没有附加_参数，因此问题不在于我的HTML.

The script tags don't have the _ param attached to them so it isn't my HTML that's the problem.

此外，未使用$.html呈现的<script>标签也没有这种现象.

Also, <script> tags that aren't rendered with $.html aren't exhibiting this behavior.

推荐答案

当jQuery在HTML中看到<script src="URL">标签时，它会在内部使用$.getScript()加载脚本.默认情况下，这会发送一个cachebuster，但是您可以通过调用$.ajaxSetup()覆盖默认的AJAX选项.

When jQuery sees a <script src="URL"> tag in the HTML, it uses $.getScript() internally to load the script. By default, this sends a cachebuster, but you can override the default AJAX options by calling $.ajaxSetup().

$(document).ready(function () {
    $.ajaxSetup({
        cache: true
    });
    var x = '<script src="https://d9zdvmiwibsh5.cloudfront.net/js/json.js">';
    $('#test').html(x);
});
