As someone mentioned above, jQuerywill do this for you, via the following syntax:

正如上面提到的，jQuery将通过以下语法为您完成此操作：

$.ajax({
    type: "DELETE",
    url: "delete_script.php",
    data: "name=someValue",
    success: function(msg){
        alert("Data Deleted: " + msg);
    }
});

You can test if your browse has DELETE implemented here

您可以测试您的浏览是否在此处实现了DELETE

Supposing req is a XMLHttpRequest object, the code would be req.open("DELETE", uri, false);

假设 req 是一个 XMLHttpRequest 对象，代码将是req.open("DELETE", uri, false);

This can be done with jQuery, if you don't mind the dependence on a framework. I believe jQueryuses XmlHttpRequestto perform this action. You'd use the $.ajaxfunction with the typeparameter set to DELETE.

jQuery如果您不介意对框架的依赖，这可以通过 来完成。我相信jQuery用于XmlHttpRequest执行此操作。您将使用参数设置为的$.ajax函数。 typeDELETE

Please note that not all browsers support HTTP DELETE requests.

请注意，并非所有浏览器都支持 HTTP DELETE 请求。

I use fetch API on one of the projects:

我在其中一个项目上使用 fetch API：

fetch(deleteEndpoint, {
  method: 'delete',
  headers: {'Content-Type': 'application/json'},
  body: JSON.stringify({id: id, token: token})
})

I have deleteEndpoint, idand tokenpreviously defined.

我有deleteEndpoint，id并且token之前定义过。

I believe that both PUT and DELETE are not implemented (in the case of Prototype) due to flaky browser support.

我相信 PUT 和 DELETE 都没有实现（在 Prototype 的情况下），因为浏览器支持不稳定。

You can use php to do this:

您可以使用 php 来执行此操作：

setup your XMLHTTPRequst to call a phpscript that deletes a named file, and then pass the filename that you intend to be removed to the php script and let it do its business.

设置您的 XMLHTTPRequst 以调用删除命名文件的 phpscript，然后将您打算删除的文件名传递给 php 脚本并让它完成它的工作。
