How to delete or post data using ajax(POST,DELETE) [duplicate]

GET:$.get(..)
POST:$.post()..
What about PUT/DELETE?

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);
})
copy from here

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.

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
}
});

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.

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.

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
});
}

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
}
});

If you need to make a $.post work to a Laravel Route::delete or Route::put just add an argument "_method"="delete" or "_method"="put".
$.post("your/uri/here", {"arg1":"value1",...,"_method":"delete"}, function(data){}); ...
Must works for others Frameworks
Note: Tested with Laravel 5.6 and jQuery 3

I've written a jQuery plugin that incorporates the solutions discussed here with cross-browser support:

GitHub Reference

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')
});

Passing parameter over jQuery GET call receive null on server side

I'm trying to make a GET call in jQuery passing a parameter here is what I'm doing
function getChirurghi() {
var id = "1";
$.ajax({
type: "GET",
url: "/api/ControllerName/GetDataHere",
contentType: "application/json; charset=utf-8",
data: id,
dataType: "json",
success: function (data) {
console.log(data);
},
failure: function (data) {
alert(data.responseText);
},
error: function (data) {
alert(data.responseText);
}
});
}
On server side the controller is called but the data I'm getting is always null...
[HttpGet]
public IEnumerable<TypeOfObject> GetDataHere([FromBody]string id)
{}
Any idea how's that happening?

You need to give the value a key so that the ModelBinder can recognise and work with it:
data: { id: id },
You also need to remove the [FromBody] attribute in the action signature, as GET data is sent in the URL (either as part of the querystring, or in a routing structure).
Lastly, the options object of $.ajax() has no failure property so that can be removed as it's redundant.

I upvoted #RoryMcrossan, but there is another solution.
you could just add it to the end of the url.
function getChirurghi() {
var id = "1";
$.ajax({
type: "GET",
url: "/api/ControllerName/GetDataHere/" + id,
contentType: "application/json; charset=utf-8",
dataType: "json",
success: function (data) {
console.log(data);
},
failure: function (data) {
alert(data.responseText);
},
error: function (data) {
alert(data.responseText);
}
});

Ajax Request: Json Data Not Being Passed to Controller

I'm building a program that searches documents in ASP.NET Core. I'm passing the search data from a text box to the controller through an Ajax request but the controller isn't receiving the string.
I've tried changing how the ajaxData field is defined, adding quotations around 'search' and even turning the whole thing into a string but I can't get it to pass to the controller.
This is the code for the request:
ajaxData = {search: $("#textSearchBox").val()}
console.log(ajaxData);
$.ajax({
type: 'POST',
url: "#Url.Action("GetDocuments", "DocumentSearchApi")",
data: ajaxData,
dataType: "json",
contentType: "application/json; charset=utf-8",
error: function (e) {
//Error Function
},
success: function (jsonData) {
//Success Function
},
fail: function (data) {
//Fail Function
}
});
And this is the top of the Controller's GetDocuments function:
[Route("GetDocuments")]
public async Task<IActionResult> GetDocuments(string search)
{
No error messages anywhere. The Console shows an Object that contains 'search: "Test"' but when I hit the breakpoint in GetDocuments 'search' is null.

I think is more elegant way to use GET in this case then you should change your code to
var ajaxData = $("#textSearchBox").val();
url: "#Url.Action("GetDocuments", "DocumentSearchApi")"?search=ajaxData
and remove data: ajaxData
Because you want to get something from the search. Using the post is when you want to modify the data from API

you need use JSON.stringify() when sending data to a web server, the data has to be a string not a object
$.ajax({
type: 'POST',
url: "#Url.Action("GetDocuments", "DocumentSearchApi")",
data: JSON.stringify(ajaxData),
dataType: "json",
contentType: "application/json; charset=utf-8",
error: function (e) {
//Error Function
},
success: function (jsonData) {
//Success Function
},
fail: function (data) {
//Fail Function
}
});

JQuery shortcut for sending ajax/JSON requests

I am working on a application that uses a REST architecture style. Hence, I often do some calls to the backend with JSON data.
jQuery is new to me and up to now, the only syntax that worked for me is :
$.ajax({
url: '/api/something/',
type: 'POST',
contentType:"application/json", //Or I will get 400 : Bad request
data: JSON.stringify({key : "value"}),
success: function (data) {
console.log("data : %o", data);
}
});
But I do not want to write explicitly contentType:"application/json" and JSON.stringify at every call. I would prefer something like :
$.someFunction({
url: '/api/something/',
type: 'POST',
data: {key : "value"},
success: function (data) {
console.log("data : %o", data);
}
});
Maybe I could make a function in order to factorize this but I feel that jQuery should have a pre-existing function for that.
Anyone knows such function?

Just wrap everything in a function and pass the parameters you need.
var thinPostWrapper = function(url, data, success) {
return $.ajax({
url: url
type: 'POST',
contentType: "application/json",
data: JSON.stringify(data),
success: success
});
}
thinPostWrapper('/api/something/', {"key" : "value"}, function(data) {
console.log("data : %o", data);
});

Try extending jQuery:
$.extend({doPost: function(url, data, success, error) {
$.ajax({
url: url,
type: 'POST',
contentType: "application/json",
data: JSON.stringify(data),
success: success,
error: error
});
}
});
$.doPost('/api/something/', {"key" : "value"}, function(data) {
console.log("data : %o", data);
});

Try
$.post(
'api/something',
{ key: 'value' },
function( data ) {
...
},
'json'
);
See http://api.jquery.com/jquery.post/ for more details

Try with $.post
$.ajax({
type: "POST",
url: url,
data: data,
success: success,
dataType: dataType
});

Jquery set HTML via ajax

I have the following span:
<span class='username'> </span>
to populate this i have to get a value from PHP therefor i use Ajax:
$('.username').html(getUsername());
function getUsername(){
$.ajax({
type: 'POST',
url: myBaseUrl + 'Profiles/ajax_getUsername',
dataType: 'json',
data: {
},
success: function(data){
document.write(data);
}
})
}
Now when i debug i see that the returned data (data) is the correct value but the html between the span tags stay the same.
What am i doing wrong?
Little update
I have tried the following:
function getUsername(){
$.ajax({
type: 'POST',
url: myBaseUrl + 'Profiles/ajax_getUsername',
dataType: 'json',
data: {
},
success: function(data){
$('.username').html('RRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRr');
}
})
}
getUsername();
Still there is no html between the tags (no text) but when i look at the console the method is completed and has been executed.
Answer to the little update
The error was in my Ajax function i forgot to print the actual response! Thank you for all of your answers, for those of you who are searching for this question here is my Ajax function:
public function ajax_getUsername(){
if ($this->RequestHandler->isAjax())
{
$this->autoLayout = false;
$this->autoRender = false;
$this->layout = 'ajax';
}
print json_encode($this->currentClient['username']);
}
Do note that i am using CakePHP which is why there are some buildin methods. All in all just remember print json_encode($this->currentClient['username']);

The logic flow of your code is not quite correct. An asynchronous function cannot return anything as execution will have moved to the next statement by the time the response is received. Instead, all processing required on the response must be done in the success handler. Try this:
function getUsername() {
$.ajax({
type: 'POST',
url: myBaseUrl + 'Profiles/ajax_getUsername',
dataType: 'json',
data: { },
success: function(data){
$('.username').html(data); // update the HTML here
}
})
}
getUsername();

Replace with this
success: function(data){
$('.username').text(data);
}

In success method you should use something like this:
$(".username").text(data);

You should set the html in callback
function getUsername() {
$.ajax({
type: 'POST',
url: myBaseUrl + 'Profiles/ajax_getUsername',
dataType: 'json',
data: {
},
success: function(data){
$('.username').html(data);
}
})
}

Add a return statement for the function getUsername
var result = "";
$('.username').html(getUsername());
function getUsername(){
$.ajax({
type: 'POST',
url: myBaseUrl + 'Profiles/ajax_getUsername',
dataType: 'json',
data: {
},
success: function(data){
document.write(data);
result = data;
}
})
return result;
}

You can use .load()
Api docs: http://api.jquery.com/load/
In your case:
$('.username').load(myBaseUrl + 'Profiles/ajax_getUsername',
{param1: value1, param2: value2});
