jQuery：操作 ![]()
后 HTML 未更新路径
我通过 jQuery 方法 load 加载外部内容，并操作之前加载的 img 元素的 src 属性，如下所示：
<div id="content"></div>
<script>
$("#content").load("additional_content.html #content table", function() {
$("#content").find("img").each(function() {
$(this).attr("src", "new_path/" + $(this).attr("src"));
});
});
</script>
在检查父 HTML 时通过 Firebug，源代码发生了变化并反映了新的图像路径。但是，浏览器中呈现的 HTML 未更新并指向旧路径。
此外，我在 Chrome 中收到以下错误：
XMLHttpRequest cannot load file:///.../additional_content.html. Origin null is not allowed by Access-Control-Allow-Origin.
有人可以帮助我吗？
I am loading external content via the jQuery method load and manipulate the src attribute of the img elements previously loaded as follows:
<div id="content"></div>
<script>
$("#content").load("additional_content.html #content table", function() {
$("#content").find("img").each(function() {
$(this).attr("src", "new_path/" + $(this).attr("src"));
});
});
</script>
While inspecting the parent HTML via Firebug, the source code changed and reflects the new image paths. However, the HTML rendered within the browser was not updated and points to the old path.
In addition, I am getting the following error within Chrome:
XMLHttpRequest cannot load file:///.../additional_content.html. Origin null is not allowed by Access-Control-Allow-Origin.
Can someone help me, please?

“Access-Control-Allow-Origin 不允许 Origin null。”发生这种情况是因为您在计算机上本地打开页面，而不是通过网址打开。 Chrome 正在检查您是否没有进行跨域调用，并决定无法验证您的调用，因为它们是本地调用。这可能是为什么图像未加载的线索 - 您给出的相对路径可能会导致问题。如果将 jQuery 中显示的 HTML 保存到新的平面 HTML 文件并在同一位置打开它，图像会显示吗？
The 'Origin null is not allowed by Access-Control-Allow-Origin.' is happening because you are opening the page locally on your machine and not via a web address. Chrome is checking you are not making cross-domain calls and has decided it can't verify your calls because they are local. This may be a clue as to why the images aren't loading - the relative path you've given may be causing issues. If you save the HTML that shows in jQuery to a new flat HTML file and open it in the same location, do the images show?
