Questions:

GET:$.get(..)

POST:$.post()..

What about PUT/DELETE?

Answers:

You could use the ajax method:

$.ajax({
    url: '/script.cgi',
    type: 'DELETE',
    success: function(result) {
        // Do something with the result
    }
});

$.ajax will work.

$.ajax({
   url: 'script.php',
   type: 'PUT',
   success: function(response) {
     //...
   }
});

We can extend jQuery to make shortcuts for PUT and DELETE:

jQuery.each( [ "put", "delete" ], function( i, method ) {
  jQuery[ method ] = function( url, data, callback, type ) {
    if ( jQuery.isFunction( data ) ) {
      type = type || callback;
      callback = data;
      data = undefined;
    }

    return jQuery.ajax({
      url: url,
      type: method,
      dataType: type,
      data: data,
      success: callback
    });
  };
});

and now you can use:

$.put('http://stackoverflow.com/posts/22786755/edit', {text:'new text'}, function(result){
   console.log(result);
})

Seems to be possible with JQuery’s ajax function by specifying

type: "put" or
type: "delete"

and is not not supported by all browsers, but most of them.

Check out this question for more info on compatibility:

Are the PUT, DELETE, HEAD, etc methods available in most web browsers?

From here, you can do this:

/* Extend jQuery with functions for PUT and DELETE requests. */

function _ajax_request(url, data, callback, type, method) {
    if (jQuery.isFunction(data)) {
        callback = data;
        data = {};
    }
    return jQuery.ajax({
        type: method,
        url: url,
        data: data,
        success: callback,
        dataType: type
        });
}

jQuery.extend({
    put: function(url, data, callback, type) {
        return _ajax_request(url, data, callback, type, 'PUT');
    },
    delete_: function(url, data, callback, type) {
        return _ajax_request(url, data, callback, type, 'DELETE');
    }
});

It’s basically just a copy of $.post() with the method parameter adapted.

You should be able to use jQuery.ajax :

Load a remote page using an HTTP
request.

And you can specify which method should be used, with the type option :

The type of request to make (“POST” or
GET“), default is “GET“.
Note: Other
HTTP request methods, such as PUT and
DELETE, can also be used here, but
they are not supported by all
browsers.

Answers:

ajax()

look for param type

Other HTTP request methods, such as PUT and DELETE, can also be used here, but they are not supported by all browsers.

Here’s an updated ajax call for when you are using JSON with jQuery > 1.9:

$.ajax({
    url: '/v1/object/3.json',
    method: 'DELETE',
    contentType: 'application/json',
    success: function(result) {
        // handle success
    },
    error: function(request,msg,error) {
        // handle failure
    }
});

Questions:
Answers:

For brevity:

$.delete = function(url, data, callback, type){

  if ( $.isFunction(data) ){
    type = type || callback,
    callback = data,
    data = {}
  }

  return $.ajax({
    url: url,
    type: 'DELETE',
    success: callback,
    data: data,
    contentType: type
  });
}

PS: use angular

You can do it with AJAX !

For PUT method :

$.ajax({
  url: 'path.php',
  type: 'PUT',
  success: function(data) {
    //play with data
  }
});

For DELETE method :

$.ajax({
  url: 'path.php',
  type: 'DELETE',
  success: function(data) {
    //play with data
  }
});

Questions:
Answers:

You could include in your data hash a key called: _method with value ‘delete’.

For example:

data = { id: 1, _method: 'delete' };
url = '/products'
request = $.post(url, data);
request.done(function(res){
  alert('Yupi Yei. Your product has been deleted')
});
