Post files with AJAX + jQuery with input element ID

I am trying to POST form data with AJAX + jQuery using the code below
<script>
$("#submit1").click(function(){
testSubmit(event);
});
function testSubmit(event) {
event.preventDefault();
var data = new FormData();
var file_data = $('input[type="file"]')[0].files; // for multiple files
for(var i = 0;i<file_data.length;i++){
data.append("file_"+i, file_data[i]);
}
var other_data = $('#form_id').serializeArray();
$.each(other_data,function(key,input) {
data.append(input.name,input.value);
});
$.ajax({
url: 'test.php',
data: data,
cache: false,
contentType: false,
processData: false,
type: 'POST',
success: function(data){
alert(data);
}
});
}
</script>
Here submit1 is a button on form form_id
This code is working fine, however the below line
data.append("file_"+i, file_data[i]);
as you can see posts the file with id of file_0, file_1 and so on. How can I get this to be the actual id of the input element rather than being a generic file_0, file_1 etc ?
Thanks for reading this

If you are using jQuery then why not something like this
$('input[type="file"]').each(function($i){
data.append($(this).prop("id"), $(this)[0].files[0]);
});
Entire Code :-
<script>
$("#submit1").click(function(){
testSubmit(event);
});
function testSubmit(event) {
event.preventDefault();
var data = new FormData();
$('input[type="file"]').each(function($i){
data.append($(this).prop("id"), $(this)[0].files[0]);
});
var other_data = $('#form_id').serializeArray();
$.each(other_data,function(key,input){
data.append(input.name,input.value);
});
$.ajax({
url: 'test.php',
data: data,
cache: false,
contentType: false,
processData: false,
type: 'POST',
success: function(data){
alert(data);
}
});
}
</script>

Not refreshing data each time

I have weired problem in my project.I have 2 tabs and in one tab i have chekboxes and submit button and user will select from checkboxes and on button click he will get what he has selected from checkboxes in another tab.It runs perfectly.But sometimes it does not refresh the data from ajax ,jquery and i have to complete refresh my page.I am not able to identify the problem as i am not getting any error. Atleast i have to click for more than 15 times then it will not refresh the data otherwise it works fine.
Here is my js code:
function getFahrzeuge() {
var opts = [];
$("#fahrzeuge input[type='checkbox']").each(function () {
if ($(this).is(':checked'))
{
opts.push($(this).attr("id"));
}
});
return opts;
}
function saveFahrzeugeWidget(opts){
if(opts.length == 0) return false;
$.ajax({
type: "POST",
url: "ajax/dashboard.php",
dataType : 'json',
cache: false,
data: {'filterOpts' :opts, 'aktion' : 'save-widget-vehicle'},
success: function(data){
//getFahrzeugeWidget();
$('#fahrzeuge').html(data['html']);
},
error: function(data){
console.log(data);
}
});
}
function getFahrzeugeWidget(opts){
if(!opts || !opts.length){
opts = allFahrzeuge;
}
$.ajax({
type: "POST",
url: "ajax/dashboard.php",
dataType : 'json',
cache: false,
data: {filterOpts:opts, 'aktion' : 'get-widget-vehicle'},
success: function(data){
$('#fahrzeuge').html(data.html);
},
error: function(data){
console.log(data);
}
});
}
function getFahrzeugeWidgetEdit(opts){
if(!opts || !opts.length){
opts = allFahrzeuge;
}
$.ajax({
type: "POST",
url: "ajax/dashboard.php",
dataType : 'json',
cache: false,
data: {filterOpts:opts, 'aktion' : 'get-widget-vehicle-edit'},
success: function(data){
$('#fahrzeuge').html(data.html);
},
error: function(data){
alert('error' + data);
}
});
}
$('#fahrzeuge .butt-rahmen').live('click', function(){
var opts = getFahrzeuge();
if($(this).attr('id') == 'saveId')
{
saveFahrzeugeWidget(opts);
if($('#fahrzeuge input[type="checkbox"]:checked').length <=0) {
alert('überprüfen Sie bitte atleast ein fahrzeuge');
//getFahrzeugeWidgetEdit(opts);
}
}
});

The answer is getting cached. And you are receiving the same answer. Try to add a new parameter to data as timestamp.
So your data should look like this.
data: {'filterOpts' :opts, 'aktion' : 'save-widget-vehicle', 'timestamp': new Date().getTime()},

Run Javascript function as long as condition is true

I'm building a PhoneGap app where user press button which then sends data to server. On the success handler I have a new function that asks user some questions with prompt box and then sends them back to server. So I need to make the prompt box appear as long as the condition "status=ok" is true.
I don't know how many times the prompt box has to appear, it can be anything from 1 to 10 times, so I guess I need to make a some sort of loop, but how can I do it?
This is the code I've been using now:
function UpdateRecord(update_id)
{ var id = getUrlVars()["id"];
jQuery.ajax({ type: "POST",
url: serviceURL + "update.php",
data: 'id='+id ,
cache: false,
success: function(data) {
console.log(data)
if(data.key[0].status == "ok"){
var reply = prompt(data.key[0].QUESTION, "");
jQuery.ajax({ type: "POST",
url: serviceURL + "question.php",
data: 'id='+id+'&reply='+reply ,
cache: false,
success: function(data) {
window.location = "page.html" }
} else {
window.location = "page.html"
}
}
});
}

I think what your after is moving the response from the AJAX call into a method AskQuestion (or whatever you want to call it). This function would prompt and would query if the answer was correct or not and redirect them to another page:
function AskQuestion(data)
{
var id = getUrlVars()["id"];
console.log(data);
if(data.key[0].status == "ok") {
var reply = prompt(data.key[0].QUESTION, "");
jQuery.ajax({ type: "POST",
url: serviceURL + "question.php",
data: 'id='+id+'&reply='+reply,
cache: false,
success: AskQuestion});
} else {
window.location = "page.html";
}
}
function UpdateRecord(update_id)
{
var id = getUrlVars()["id"];
jQuery.ajax({ type: "POST",
url: serviceURL + "update.php",
data: 'id='+id,
cache: false,
success: AskQuestion});
}

Ajax post method not working

I am currently creating a website and am having trouble using AJAX to post my data. I have a button and when clicked the following code is processed...
var name = document.getElementById('name').innerHTML;
var text = document.getElementById('text').innerHTML;
$.ajax({
type: "POST",
url: "php/post.php",
data: { postName: name, postText: text},
success: function() {
$('#paragraph').html("worked");
}
});
This definitely opens the post.php page but it is not passing through the desired data. Am I doing something wrong?
Thanks in advance

What do the variables name and text contain? Rather than doing
var name = document.getElementById('name').innerHTML;
var text = document.getElementById('text').innerHTML;
You can do:
var name = $("#name").val();
var text = $("#text").val();
You may need to pass the datatype object too:
$.ajax({
type: "POST",
url: "php/post.php",
data: { postName: name, postText: text},
dataType: "json",
success: function() {
$('#paragraph').html("worked");
}
});

var name = $('#name').text();
var text = $('#text').text();
$.ajax({
type: "POST",
url: "php/post.php",
data: { postName: name, postText: text},
dataType: 'json',
success: function() {
$('#paragraph').html("worked");
}
});

I guess you are not preventing the default button click behaviour. Probably you should use the preventDefault function on the button click to stop processing the default form posting. Also make sure you have the content present inside your form elements with the Id name and text
$(function(){
$("#yourButtonId").click(function(e){
{
e.preventDefault();
var name = $('#name').html();
var text = $('#text').html();
if(name!="")
{
$.ajax({
type: "POST",
url: "php/post.php",
data: { postName: name, postText: text},
success: function() {
$('#paragraph').html("worked");
}
});
}
else
{
alert("Why should i do ajax when content is empty!");
}
});
});

var name = document.getElementById('name').value,
text = document.getElementById('text').value,
postData = JSON.stringify({ postName: name, postText: text});
$.ajax({
type: "POST",
url: "php/post.php",
data: postData,
success: function() {
$('#paragraph').html("worked");
}
});
You will need to include a reference to json2.js for this to work in older browsers. You can download it here : https://github.com/douglascrockford/JSON-js

Ajax on success of another ajax doesn't work in ie

I do an ajax call to get a list of all elements, say Products and populate them in a table with checkboxes. Then I make another ajax call to get which products were already selected and select them. This works in all browsers except ie. Am I doing something wrong?
$.ajax({
url : "${product_category_url}",
data : {"orgID":"${globalOrganisation.id}"},
dataType : "html",
statusCode: {
401: function() {
$('.ui-tabs-panel:visible').html("${ajax_session_expired}");
}
},
success : function(data) {
$("#productCategoryContainer").html(data);
$.ajax({
url: "${get_taggedProd_url}",
data: {"questionnaireId":_questionnaireId},
dataType: "json",
success: function(data){
var productIds = data.products;
$.each(productIds,function(index,value){
var obj = $('input[name="'+value+'"]');
obj[0].checked = true
selectRow(obj[0]);
});
}
});
}
});

This is due to caching by IE.
Please try this
$.ajax({
url : "${product_category_url}",
data : {"orgID":"${globalOrganisation.id}"},
dataType : "html",
statusCode: {
401: function() {
$('.ui-tabs-panel:visible').html("${ajax_session_expired}");
}
},
success : function(data) {
$("#productCategoryContainer").html(data);
$.ajaxSetup ({
// Disable caching of AJAX responses
cache: false
});
$.ajax({
url: "${get_taggedProd_url}",
data: {"questionnaireId":_questionnaireId},
dataType: "json",
success: function(data){
var productIds = data.products;
$.each(productIds,function(index,value){
var obj = $('input[name="'+value+'"]');
obj[0].checked = true
selectRow(obj[0]);
});
}
});
}
});
and if you need more details please look into this

The thing in this code that always screws me up is trying to get the check box selected. Make sure obj[0].checked = true actually works.
