Send js varible to php file with ajax

I would like to send my variable "var targetId" to my php file.
I try to make ajax request but nothing happens.
My js file :
$( ".project_item" ).click(function(e){
var targ = e.target;
var targetId = targ.dataset.id;
console.log(targetId);
$('.popUp').fadeIn("200");
$('header, main, footer').addClass('blur');
$.ajax({
url: 'function.php',
type: "POST",
data: {idVoulu: targetId},
success: function(data){
alert(data);
console.log(data);
}
});
});`
And my php file to get the data
$idProject = (isset($_POST['idVoulu'])) ? $_POST['idVoulu'] : 0;
if($idProject==0) { echo ' ID not found';}
Can you tell me what's going wrong?

Well I can't Find a problem on your code but you can try this may be this will help you
var mydata = "idVoulu='+targetId+'"; // make a string
$.ajax({
url: 'function.php',
type: "POST",
data: mydata,
success: function(data){
alert(data);
console.log(data);
}
});

So, i made this and it works:
My js:
$( ".project_item" ).click(function(e) {
var targ = e.target;
var targetId = targ.dataset.id;
$('.popUp').fadeIn("200");
$('header, main, footer').addClass('blur');
$.post('../function.php', { id: targetId }, function(response) {
console.log("reponse : ", response)
});
My php :
if (isset($_POST['id'])) {
$newID = $_POST['id'];
$response = 'Format a response here' . $newID;
return print_r($response);
}

Fetch Data in a form through Ajax in Laravel

I am making an auto-complete form, in which user enter only the id and the whole information related to that id comes in other field. I am using ajax and Laravel 5.4. The Data is coming in alert but how i can insert data in input fields of a form. Here is my script:
<script type="text/javascript">
$('#submitid').on('click', function() {
var vid = $( "#vid" ).val();
//var id=$(this).data('id');
$.ajax({
url: '/inquiryVendor',
type: "Get",
data:{id:$("#vid").val()}, // the value of input having id vid
success: function(response){ // What to do if we succeed
alert(response); console.log(response);
}
});
});
</script>
this is my controller:
public function VendorDetail(Request $request)
{
$id= $request->id;
$data = DB::select(DB::raw("SELECT * from bp where id = '$id'"));
echo json_encode($data);
}
here is my console.log response:
[{"id":37,"card_name":"Maka Furniture Co.,Ltd ","trade_type":"Manufacturer","address":"Xinzhang development zones,Shengfang town,Hebei province.","fc":"121AC209","status":0,"created_at":"2018-10-10 10:02:27","user":"admin"}]
here is the screenshot of response:
Any help would be highly appreciable.

If you want all data in single input you can use this
<script type="text/javascript">
$('#submitid').on('click', function() {
var vid = $( "#vid" ).val();
//var id=$(this).data('id');
$.ajax({
url: '/inquiryVendor',
type: "Get",
dataType: 'json',//this will expect a json response
data:{id:$("#vid").val()},
success: function(response){
$("#inputfieldid").val(response);
}
});
});
</script>
or if you want on different input field you can do like this
<script type="text/javascript">
$('#submitid').on('click', function() {
var vid = $( "#vid" ).val();
//var id=$(this).data('id');
$.ajax({
url: '/inquiryVendor',
type: "Get",
dataType: 'json',//this will expect a json response
data:{id:$("#vid").val()},
success: function(response){
$("#inputfieldid1").val(response.id);
$("#inputfieldid2").val(response.2ndcolumnName);
$("#inputfieldid").val(response.3rdcolumnName);
}
});
});
</script>

In your other fields you can do the following in success method:
success: function(response) {
$('.input1').val(response.input1);
$('.input2').val(response.input2);
$('.label1').html(response.label1);
}
I hope it would helpful.

add unique ID property to your input like this:
<input id="name" type="text">
Then fill this input with ajax result by this code:
<script type="text/javascript">
$('#submitid').on('click', function() {
var vid = $( "#vid" ).val();
//var id=$(this).data('id');
$.ajax({
url: '/inquiryVendor',
type: "Get",
data:{id:$("#vid").val()}, // the value of input having id vid
success: function(response){ // What to do if we succeed
$('#name').val(JSON.parse(response)[0].name); //<---- This line,
}
});
});
</script>
Do this for all your input base you logic.

Suppose you have input fields like this in your form
<input type="text" name="vendor_name" id="vendor_name">
<input type="text" name="vendor_mobile" id="vendor_mobile">
<input type="text" name="vendor_email" id="vendor_email">
You ajax code should be like this and I hope you get the parameters in your JSON response
<script type="text/javascript">
$('#submitid').on('click', function() {
var vid = $( "#vid" ).val();
//var id=$(this).data('id');
$.ajax({
url: '/inquiryVendor',
type: "Get",
data:{id:$("#vid").val()}, // the value of input having id vid
success: function(response){ // What to do if we succeed
$('#vendor_name').val(response.vendor_name)
$('#vendor_mobile').val(response.vendor_mobile)
$('#vendor_email').val(response.vendor_email)
}
});
});
</script>
If this can't help then could you please do console.log(response) and paste the debug data so it will be easy to help you more.
<script type="text/javascript">
$('#submitid').on('click', function() {
var vid = $( "#vid" ).val();
//var id=$(this).data('id');
$.ajax({
url: '/inquiryVendor',
type: "Get",
data:{id:$("#vid").val()}, // the value of input having id vid
success: function(response){ // What to do if we succeed
console.log(response)
}
});
});
</script>
if you don't want response[0] then you need to change in your controller File like this.
$vendor = DB::table('bp')->where('id', '.$id.')->first();
return response()->json($vendor);
As per your need, this will help for sure.

JQuery Autocomplete and AJAX combination

I'm trying to implement auto-complete on a textbox in php. The data from autocomplete is retrieved using a GET ajax call (which calls a certain api and returns json output).
The code for my ajax was as follows:
<script type="text/javascript">
$(function() {
$( "#tags" ).keyup(function() {
var query = document.getElementsByName('newartist')[0].value;
$.ajax({
type: "GET",
url: "https://lab.anghami.com/rest/v1/SEARCHedge.php",
data: "output=jsonhp&q=" + query,
dataType: "html",
success: function (data) {
var obj = JSON.parse(data);
console.log("1. " + obj[0]);
console.log("2. " + obj[1]);
}
});
});
});
</script>
This code was working perfectly find, and the output was shown in the console correctly. Next I tried adding this ajax call as "source" to my autcomplete call as follows:
<script type="text/javascript">
$(function() {
var query = document.getElementsByName('newartist')[0].value;
$( "#tags" ).autocomplete({
source: function( request, response ) {
$.ajax({
type: "GET",
url: "https://lab.anghami.com/rest/v1/SEARCHedge.php",
data: "output=jsonhp&q=" + query,
dataType: "html",
success: function (data) {
var obj = JSON.parse(data);
var outp = [];
outp.push(obj.sections[0].data[0].name);
outp.push(obj.sections[0].data[1].name);
console.log(obj.sections[0].data[0].name);
console.log(obj.sections[0].data[1].name);
response(outp);
}
});
}
});
});
</script>
Here, the code stopped working for some reasons, and any console.log commands I had stopped outputting the results.
One other method I found as answer to a similar question was to implement the following code:
<script type="text/javascript">
$(function() {
$( "#tags" ).keyup(function() {
var query = document.getElementsByName('newartist')[0].value;
$.ajax({
type: "GET",
url: "https://lab.anghami.com/rest/v1/SEARCHedge.php",
data: "output=jsonhp&q=" + query,
dataType: "html",
success: function (data) {
var obj = JSON.parse(data);
var artists = [];
artists.push(obj[0]);
artists.push(obj[1]);
test(obj);
}
});
});
});
function test(data){
console.log(data);
$("#tags").autocomplete({
source: data
});
}
</script>
This was a bit better as autocomplete was indeed suggesting results, but it was inconsistent as it sometimes outputted 1 result instead of 2 (my ajax call ALWAYS returns 2 results, and I made sure that it's always the case by using console.log), and sometimes the suggestions proposed by autocomplete were those of the previous AJAX call and not the current one (again, console showed new results but autocomplete suggested previous ones.
If you could point to the errors in both of these methods, it would be great.
Thanks!!

Code looking fine. Please mention the JSON output format.

Suppressing and adding parameters for ajax call

I am trying to make an ajax call for two separate click events. The difference is for the second click event the variable testOne should not be part of the call and instead there would be a new variable. How should I approach this?
var varOne = '';
var varTwo = '';
var varThree = '';
function testAjax(){
$.ajax({
type: "POST",
dataType: 'html',
url: "http://someblabla.php",
data: {
testOne: varOne,
testTwo: varOne
}
}).done(function(data) {
$('.result').html(data);
});
}
$('.clickOne').click(function(){
varOne = 'xyz123';
varTwo = '123hbz';
testAjax();
});
$('.clickTwo').click(function(){
//varOne = 'xyz123'; // I dont need this for this click
varTwo = '123hbz';
varThree = 'kjsddfag'; // this gets added
testAjax();
});
<div class="clickOne"></div>
<div class="clickTwo"></div>

Make some like this
function testAjax(data){
$.ajax({
type: "POST",
dataType: 'html',
url: "http://someblabla.php",
data: data,
}).done(function(data) {
$('.result').html(data);
});
}
$('.clickOne').click(function(){
var data= {
varOne: 'xyz123',
varTwo: '123hbz',
}
testAjax(data);
});
$('.clickTwo').click(function(){
var data= {
varThree : 'kjsddfag',
varTwo: '123hbz',
}
testAjax(data);
});
<div class="clickOne"></div>
<div class="clickTwo"></div>

You can also do the same in other way with minimum line of code, you can call the ajax on click event and pass the data based on the element triggered the click event.
like this:
$('.ajax').click(function(e){
if($(this).hasClass('clickOne')){
var data= { varOne: 'xyz123'; varTwo: '123hbz'; }
}else{
var data= { varThree : 'kjsddfag'; varTwo: '123hbz'; }
}
$.ajax({
type: "POST",
dataType: 'json',
url: "http://someblabla.php",
data: data,
}).done(function(data) {
$('.result').html(data);
});
e.preventDefault();
});
<div class="ajax clickOne"></div>
<div class="ajax clickTwo"></div>
In this way you can put as many conditions for different data variable.

You should be doing it like this:
function testAjax(data){
$.ajax({
type: "POST",
dataType: 'html',
url: "http://someblabla.php",
data: data
}).done(function(data) {
$('.result').html(data);
});
}
$('.clickOne').click(function(){
var data {
varOne = 'xyz123',
varTwo = '123hbz'
}
testAjax(data);
});
$('.clickTwo').click(function(){
var data = {
varTwo = '123hbz',
varThree = 'kjsddfag'
}
testAjax(data);
});
<div class="clickOne"></div>
<div class="clickTwo"></div>
This way you absolute control over which variables are added to which ajax call. You should not use global variables unless you really need them to be global, which doesn't seem to be the case.
You can pass whatever JavaScript object to the data parameter of the ajax method.

I just wanted to add something. I often hide value inside the value attribute of the button tags to produce something like this.
I haven't been able to test this of course but I thought it was worth mentioning.
jquery:
var fields = '';
function testAjax(){
$.ajax({
type: "POST",
dataType: 'html',
url: "http://someblabla.php",
data: fields
}).done(function(data) {
$('.result').html(data);
});
}
$('#btn').click(function(){
var varCount = 0;
var vars = $(this).val().split('|');
$.each( vars, function( key, value ) {
varCount++;
fields = fields + 'var' + varCount + '=' + value + '&';
});
fields = fields.slice(0,-1);
$(this).val('123hbz|kjsddfag');
testAjax();
});
html:
<button id="btn" value="xyz123|123hbz"></button>

A more optimized and cleaner version -
var varTwo='junk1'
var varOne='junk2'
var varThree='junk3'
function testAjax(data){
$.ajax({
type: "POST",
dataType: 'html',
url: "http://someblabla.php",
data: data,
}).done(function(data) {
$('.result').html(data);
});
}
$('.ajaxClick').click(function(){
var data={};
if(this.classList.contains('clickOne')){
data.varOne=varOne;
data.varTwo=varTwo;
}else{
data.varThree=varThree;
data.varTwo=varTwo;
}
testAjax(data);
});
<div class="ajaxClick clickOne"></div>
<div class="ajaxClick clickTwo"></div>

jquery autocomplete not populating unless entered text is in the first result

Im having an issue with jquery autocomplete plugin. the textbox im using wont populate the results of autocomplete until i enter a value that is in the first entry of my data. After it populates that, then the autocomplete works how its supposed to.
$(document).ready(function () {
});
function textChange() {
var callback = function (request, response) {
var searchText = request.item;
var searchField = $(".ddlist > option:selected").attr("value");
$.ajax({
type: "GET",
dataType: "text",
url: "SearchCallback.aspx?searchText=" + searchText + "&searchField=" + searchField,
success: function (data) {
var splitData = data.split(",");
response(splitData);
}
});
}
$(".searchTextBox").autocomplete({
source: callback,
autoFill: true
})
}
after playing around with it i got the following code to work, before i was using an onkeyup event in the text box but i guess i didnt need it. i dont know if this is efficient but it is working correctly now.
$(document).ready(function () {
$(".searchTextBox").autocomplete({
source: callback,
autoFill: true
});
});
var callback = function (request, response) {
var searchText = request.term;
var searchField = $(".ddlist > option:selected").attr("value");
$.ajax({
type: "GET",
dataType: "text",
url: "SearchCallback.aspx?searchText=" + searchText + "&searchField=" + searchField,
success: function (data) {
var splitData = data.split(",");
response(splitData);
}
});
}

You have to use a callback as the source option when you initialize the autocomplete (in your example you initialize the autocomplete every time a key is being pressed):
var callback = function(request, response) {
var searchText = request.item;
// Set searchField somehow here
$.ajax({
type: "GET",
dataType: "text",
url: "SearchCallback.aspx?searchText=" + searchText + "&searchField=" + searchField,
success: function (data)
{
var splitData = data.split(",");
response(splitData);
});
});
};
$( ".searchTextBox" ).autocomplete({
source: callback,
autoFill: true
});
There are some more examples and a more detailed description in the documentation.
