So I want to make a http request with a body (say file, file2, file3) and arguments like action=delete how to make such request with jquery?
Pass parameters with url and files with body:
$.ajax({
url: 'someurl' + '?action=delete',
type: 'POST',
data: requestbodyhere,
success: function(responseData){
}
});
You want to do a POST? You can do that using Ajax:
jQuery.ajax({
type: 'POST',
url: url,
data: {
file1:'file1',
flie2:'file2'
},
success: function(response) {
//in response you have the answer from the server as a string
}
});

I want to call a json data inside my AJAX success. I'm still new on manipulating json and AJAX. Can somebody help me on how to access my json data which is from another URL? And I want to compare the id to the JSON data. Here's my code so far:
function getCard(id){
$.ajax({
type: "GET",
data: "id=" + id,
success: function(data){
#call JSON data here from another URL
# Is it possible to call another AJAX here?
}
});
}
This code will work for you
$.ajax({
url: "url",
method: "post",
data: "id=" + id,
success:function(data) {
// success goes here
$.ajax({
url: "url",
async:false,
method: "post",
data: "id=" + id,
success:function(json) {
JSON.parse(json);
// compare data and json here
},
error: function(){
// error code goes here
}
});
},
error: function(){
// error code goes here
}
});
yes Zuma you can call another Ajax inside Success function of Ajax call. Below is the example:
$.ajax({
type: "post",
url: url1,
data: data1,
success: function(data){
$.ajax({
type: "post",
url: url2,
data: data2,
success: function(data){
});
});
});
function getCard(id){
$.ajax({
type: "Get",
url: "发送请求的地址",
data: "id=" + id,
success: function(data){
#call JSON data here from another URL
# if success,you can call another AJAX.
# Is it possible to call another AJAX here?
# yes!
}
});
}
I have a GET request:
$.ajax({
url: '/items?ids=' + value.join(','),
method: 'get',
dataType: 'json'
})
How can I create a POST request from this?
$.ajax({
url: 'url_here',
method: 'post',
data: {
fName1: value1,
fName2: value2,
...
},
dataType: 'json'
});
The way of post requests works are different from the get request, in http post request you need to pass the values in the body of your request as bellow :
$.ajax({
url: "/items",
contentType: "application/json",
type: "POST",
data: {
"id": $("#id").val(),
"value1": $("#value1").val(),
"value2": $("#value2").val()
}
});
you can use fiddler to debug and watch what going on the wire.
I have a webform which has x number of textboxes and y number of dropdowns etc
I am using this code to send data to webmethod at the server:
$.ajax({
type: "POST",
url: "SupplierMaster.aspx/RegisterSupplier",
data: JSON.stringify({
id: $('#txtbidderid').val(),
bidamt: $('#txtbidamt').val()
}),
contentType: "application/json; charset=utf-8",
dataType: "json",
async: true,
success: function (data, status) {
alert(data.d);
},
failure: function (data) {
alert(data.d);
},
error: function (data) {
alert(data.d);
}
});
Now the problem is that I also want to include file attachments on this form.
How do I add the files to data: of $.ajax method?
I do not want to use external plugins etc unless absolutely necessary.
Lets say I modify my data object to look like this :
var dataToSend = {};
dataToSend.id = $('#txtbidderid').val()
dataToSend.bidamt = $('#txtbidamt').val()
dataToSend.append( 'file', input.files[0] );
What would the webmethod armument look like?
For example lets suppose it looks like this as of now:
[WebMethod] public static string SubmitBid(string id, string bidamt.....)
You can try something like this. You may need to manipulate content type.
var dataToSend = new FormData();
dataToSend.append( 'file', input.files[0] );
$.ajax({
url: "SupplierMaster.aspx/RegisterSupplier",
data: dataToSend,
processData: false,
contentType: false,
type: 'POST',
success: function(data){
alert(data);
}
});
You cannot send file as application/json; charset=utf-8 to the server and so i suggest you to use application/x-www-form-urlencoded as contentType and also data as FormData as below.
$.ajax({
url: "SupplierMaster.aspx/RegisterSupplier",
type: 'POST',
data: new FormData(formElement),//Give your form element here
contentType: false,
processData: false,
success: function () {
//do success
}
});
Hello I'm performing a GET request on a RESTful Rails resource, like so:
function getGroups(category) {
$.ajax({
type: 'GET',
url: 'http://localhost:3000/groups.json',
data: JSON.stringify({"access_token":"569669d8df0456", "category":category }),
success: function(data) {alert(data)},
contentType: "application/json",
dataType: 'json'
});
});
getGroups("own_groups");
The problem is that Webrick server errors out like this:
ERROR bad URI
`/groups.json?{%22access_token%22:%22569669d8df0456%22,%22category%22:%22own_groups%22}'.
It must be something related with how the JSON data is parsed, because I am having no problems with another GET request WITHOUT JSON data, and a POST request WITH JSON data...
Update: adding code for POST request (where JSON.stringify is required)
function addGroup(name, description) {
$.ajax({
type: 'POST',
url: 'http://localhost:3000/groups.json',
data: JSON.stringify({"access_token":"569669d8df0456", "group_name":name, "group_description":description}),
success: function(data) { alert("ok")},
contentType: "application/json",
dataType: 'json'
});
};
addGroup("nice group", "full of people");
Do not use JSON.stringify. Simply put:
data: {"access_token":"569669d8df0456", "category":category },
Moreover, you do not need to specify complete url http://localhost:3000/groups.json, it can be just simply groups.json
I have the following code:
$("form").submit(function()
{
//Checking data here:
$("input").each(function(i, obj)
{
});
alert(JSON.stringify($(this).serializeArray()));
var url='http://127.0.0.1:1337/receive';
$.ajax({
url: url,
type: 'POST',
contentType:'application/json',
data: JSON.stringify($(this).serializeArray()),
dataType:'json'
});
});
And after I submit the form, I get a JavaScript alert with the json string, so that is made correct (on my server I only log it so it does not matter what it is in it). If I try to send a request to the same link from postman it works, it logs it.
I think I'm doing something wrong in the ajax call, but I am not able to figure out.
Try below piece of code. Add success and error handler for more details
$("form").submit(function()
{
//Checking data here:
$("input").each(function(i, obj)
{
});
alert(JSON.stringify($(this).serializeArray()));
var url='http://127.0.0.1:1337/receive';
$.ajax({
url: url,
type: 'POST',
contentType: 'application/json; charset=utf-8',
data: JSON.stringify($(this).serializeArray()),
dataType:'json',
success : function(response) {
alert("success");
},
error: function (xhr, status, error) {
alert(error);
}
});
});
data:{ list : JSON.stringify($(this).serializeArray())}
From the Jquery docs:
Due to browser security restrictions, most "Ajax" requests are subject to the same origin policy; the request can not successfully retrieve data from a different domain, subdomain, or protocol.
crossDomain attribute simply force the request to be cross-domain. dataType is jsonp and there is a parameter added to the url.
$.ajax({
url:'http://127.0.0.1:1337/receive',
data:{ apikey: 'secret-key-or-any-other-parameter-in-json-format' },
dataType:'jsonp',
crossDomain: 'true',
success:function (data) {alert(data.first_name);}
});
