Ajax post multiple variables via loop? - javascript

I am trying to post multiple variables from the already dynamically create-able "username" id's such as "username1", "username2", etc. I'm looking for a way to dynamically send these into ONE ajax post request. My problem is mainly with the data parameter.
var numOfInputs = $('input').length;
$.ajax({
type: "POST",
url: "ajax.php",
// need way to dynamically pass more of these via numOfInputs.
data: ({username1 : $('#username1').val()}),
success: function(msg){
$('#statuses').html(msg);
}
});
requested html:
<input type="text" id="username1"></input><button id="add">+</button><button id="check">Check</button>
<div id="added-fields">
</div>
<div id="statuses">
</div>

var data = {};
for (var i = 1; i <= numOfInputs; i++) {
data["username" + i] = $("#username" + i).val();
}
$.ajax(
...
data: data,
....
)

Well you can say:
$.ajax({
type: "POST",
url: "ajax.php",
data: $('input').map(function() {
var o = {};
o[this.id] = this.value;
return o;
});

How to display JSON using ajax

I want to display the value based on selected value on drop down list with using Get method of Ajax from the url,
based on schema i have to add the value of selected item to the meddle of url and then i can get the relative data from the server:
this is my code:
$.ajax({
type: 'GET',
url: 'url',
success: function(data) {
for (var i = 0; i < data.length; i++) {
$("#tbl2").append("<option>"+data[i]+"</option>");
}
}
});
var one = 'http://gate.atlascon.cz:9999/rest/a/';
var middle = $('#tbl2 :selected').text(); // it should be the selected item from last get method
var end = '/namespace';
var url_t = one + middle + end ;
$.ajax({
type: 'GET',
url: url_t,
success: function(data2) {
$("#text-area").append(data2);
}
but it is not work!
i am new in programming, could you please help me.
thanks.
try this:
$.ajax({
type: 'GET',
url: 'url',
success: function(data) {
for (var i = 0; i < data.length; i++) {
$("#tbl").append("<tr><td>"+data[i]+"</td></tr>");
}
}
});
Add this in your ajax success():
data.forEach(function(item) {
$("#tbl").find('tbody')
.append($('<tr>')
.append($('<td>').text(item))
);
})

Sending files with ajax not working as expected

I have a form which gets files along with other inputs , I want to pass those data to my ajax function. But when i check for those files in server , the server doesn't receive the file. I am new to ajax and Jquery. Here is what i have done.
<form id = "comp_inter_form">
<input type="radio" name="inter_fit" id="inter_good_fit" value = "good" >
<input type="radio" name="inter_fit" id="inter_bad_fit"
<input id="report_upload" type="file"/>
<input id="skype_upload" type="file"/>
<input id="audio_upload" type="file"/>
<input type = "submit" class = "update_interview_btn btn btn-primary" value = "Update"/>
</form>
Ajax function
function completeInterview(id,profile_id){
console.log("Candidate ID is : "+id+"\n Profile id is :"+profile_id );
$('#completeIntModal').modal('show');
var candidate_id = id;
var profile_id = profile_id;
var inter_fit,report_file,skype_file,audio_file;
$("#comp_inter_form").on('submit',function(){
var inter_fit = $("input[name=inter_fit]:checked").val();
var report_file = $("#report_upload").prop('files');
var skype_file = $("#skype_upload").prop('files');
var audio_file = $("#audio_upload").prop('files');
var dataString = 'inter_fit=' +inter_fit+ '&report_file=' +report_file+ '&skype_file=' +skype_file+ '&audio_file=' +audio_file+ '&candidate_id=' +candidate_id+ '&profile_id=' +profile_id;
$.ajax({
type: "POST",
url: "/complete_interview",
headers: {'X-CSRF-TOKEN': $('meta[name="csrf-token"]').attr('content')},
data: dataString,
cache: false,
success: function(data) {
alert(data.msg);
},
error : function(xhr ,status ,error)
{
console.log(xhr);
alert(xhr);
}
});
});
Please try to make it like following and check if it works, As you are trying to post content VIA ajax with file input, it has to be treated separately.
You have to use FormData for this.
$("#comp_inter_form").on('submit',function(){
var inter_fit = $("input[name=inter_fit]:checked").val();
var report_file = $("#report_upload").prop('files');
var skype_file = $("#skype_upload").prop('files');
var audio_file = $("#audio_upload").prop('files');
var dataString = 'inter_fit=' +inter_fit+ '&report_file=' +report_file+ '&skype_file=' +skype_file+ '&audio_file=' +audio_file+ '&candidate_id=' +candidate_id+ '&profile_id=' +profile_id;
var formData = new FormData();
formData.append("inter_fit",inter_fit);
formData.append("candidate_id",candidate_id);
formData.append("profile_id",profile_id);
var fileInput = $("#report_upload").get(0);
formData.append("report_file",fileInput.files[0]);
fileInput = $("#skype_upload").get(0);
formData.append("skype_file",fileInput.files[0]);
fileInput = $("#audio_upload").get(0);
formData.append("audio_file",fileInput.files[0]);
$.ajax({
type: "POST",
url: "/complete_interview",
headers: {'X-CSRF-TOKEN': $('meta[name="csrf-token"]').attr('content')},
data: formData,
contentType: false, // Not to set any content header
processData: false, // Not to process data
cache: false,
success: function(data) {
alert(data.msg);
},
error : function(xhr ,status ,error)
{
console.log(xhr);
alert(xhr);
}
});
On the server side you need to check for posted file array and process those accordingly.

Ajax Response add under each element

I have a question that I can't seem to answer about Jquery Ajax Response.
I use a for each to select some data from <p> tags in each info_div. This data I then use to do a ajax call to a service that replies with a XML. I want to place some elements from this XML under each div from where I took the two variables. Each div should have it's own reply.
$(document).ready(function () {
$('#action-button').click(function () {
$(".info_div").each(function () {
var var1 = $(this).find('p:nth-child(4)').text();
var1 = var1.slice(-10);
var var2 = $(this).find('p:nth-child(8)').text();
var2 = var2.slice(-1);
$.ajax({
type: "GET",
url: "http://www.mypage.com/mypage&value1=" + "va1" + "&value2=" + "var2",
cache: false,
dataType: "xml",
success: function (xml) {
$(xml).find('member').each(function () {
var name = $(this).find("title").text()
/* how do I get this variable under each $('.info_div') from where I selected the var1 and var2
Every attempt I made places all replies under all the divs in class .info_div */
});
}
});
});
});
});
I would not recommend you to send ajax requests in a loop. Better collect all your data, then send it to the server and handle the response.
Meanwhile, if you insist to do it in a loop, you should make a reference to the iterated element from $(".indo_div) collection, and use it in ajax callback.
$(".info_div").each(function() {
var _that = $(this);
var var1 = $(this).find('p:nth-child(4)').text();
var1 = var1.slice(-10);
var var2 = $(this).find('p:nth-child(8)').text();
var2 = var2.slice(-1);
$.ajax({
type: "GET",
url: "http://www.mypage.com/mypage&value1=" + "va1" + "&value2=" + "var2",
cache: false,
dataType: "xml",
success: function(xml) {
$(xml).find('member').each(function(){
var name = $(this).find("title").text()
that.append(name);
});
}
});
});

Unexpected characters in image url in ajax response Javascript

In My Codeigniter web application I'm using an ajax function to get some data from the database inorder to show it in the view.The data from database contains an image url and other fields.
My problem is that when I get the data in ajax success function, the image url looks like this:
<button id='product-1301' type='button' value=1301 class='blue' ><i><img src='assets\/uploads\/thumbs\/default.png'></button>
Since the url contains these characters \ my view is not rendering properly. I tried using stripslash function to remove this. But didn't work. I didn't know where am going wrong.
my ajax function
$.ajax({
type: "get",
url: "index.php?module=pos&view=ajaxproducts1",
data: {category_id: cat_id, per_page: p_page},
dataType: "html",
success: function(data) {
var x= data;
alert(x);
if(data!=1)
{
$('#proajax').empty();
var newPrs = $('<div></div>');
newPrs.html(data);
newPrs.appendTo("#proajax");
//$('#gmail_loading').hide();
}
else
{
bootbox.alert('Product is Not Available in this Category!');
$('#gmail_loading').hide();
}
}
});
Controller
function ajaxproducts1()
{
$mn;$data1;
$img="assets/uploads/thumbs/default.png"; //this is my image path, when this comes in ajax success,\ character adds
$img=str_replace('\"', '', $img);
if($this->input->get('category_id')) { $category_id = $this->input->get('category_id'); }
if($this->input->get('per_page')) { $per_page = $this->input->get('per_page'); }
if($item = $this->pos_model->getProductsByCategory($category_id,$per_page))
{
foreach ($item as $i)
{
$button="<button id='product-".$i->id."' type='button' value=".$i->id." class='blue' ><i><img src='".$img."'><span><span>".$i->name;
$mn=$mn.$button;
}
$data1=$mn;
}
else
{
$data1=1;
}
echo json_encode($data1);
}
Can anyone help me with this ?
Try this:
// use an array to gather up all the values
// call encodeURIComponent() on the variables before adding them
// join them all together and pass them as "data"
var tempVars=['module=pos&view=ajaxproducts1'];
tempVars.push('category_id='+encodeURIComponent( cat_id ));
tempVars.push('userInfo='+encodeURIComponent( p_page ));
var sendVars=tempVars.join('&');
$.ajax({
type: "get",
url: "index.php",
data: sendVars,
dataType: "text",
success: function(data) {
var x = data;
alert(x);
if (data != 1) {
$('#proajax').empty();
var newPrs = $('<div></div>');
newPrs.html(data);
newPrs.appendTo("#proajax");
//$('#gmail_loading').hide();
} else {
bootbox.alert('Product is Not Available in this Category!');
$('#gmail_loading').hide();
}
}
});
My issue was solved by using jQuery.parseJSON function.

How Can I Do to my textbox autocomplete, works

I'm trying to do an autocomplete to my textbox, but it doesn't work. Follow my code.
$(function () {
var credenciada = '<%= credenciadaId %>';
xml_NomeCompleto = "";
var Nomes = "";
var retorno = '';
var count = 0;
var t = '';
$.ajax({
url: "../Xml/AcessoExterno.aspx?Credenciada=" + credenciada,
type: "get",
dataType: 'xml',
async: false,
success: function (data) {
$(data).find("REGISTRO").each(function () {
t = $(this).find("NOMECOMPLETOUSUARIO").text();
Nomes += ["\"" + t + "\","];
});
}
});
$("#ctl00_contentConteudo_txtNome").autocomplete({ source: Nomes });
});
The variable 't' receives all the names of my users, normally, but the autocomplete don't work.
Wait for ajax response to complete and then initialize the autocomplete because before you initialize the plugin data is not available. Also the way you are creating Nomes(source) is wrong. Declare it as an array and use push method to populate it.
Try this
var Nomes = [];
$.ajax({
url: "../Xml/AcessoExterno.aspx?Credenciada=" + credenciada,
type: "get",
dataType: 'xml',
async: false,
success: function (data) {
$(data).find("REGISTRO").each(function () {
Nomes.push($(this).find("NOMECOMPLETOUSUARIO").text());
});
$("#ctl00_contentConteudo_txtNome").autocomplete({ source: Nomes });
}
});
