How can I send a http delete request from browser?

问题:

Is there a way to send a DELETE request from a website, using xmlhttprequest or something similar?

回答1:

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

$.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

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

This can be done with jQuery, if you don't mind the dependence on a framework. I believe jQuery uses XmlHttpRequest to perform this action. You'd use the $.ajax function with the type parameter set to DELETE.

Please note that not all browsers support HTTP DELETE requests.

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

回答5:

I use fetch API on one of the projects:

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

I have deleteEndpoint, id and token previously defined.

You can use php to do this:

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.
