I hope you are fine!
I'm new in coding so I'm facing of something without results.
I have this type of code here in JS.
key: 'generateChart2',
value: function generateChart2() {
var self = this;
var Jahr1 = [];
var years1 = "";
for (var i = 0; i < $('#mf123_select_jahr').val().length; i++) {
if (i > 0) years1 += ","
years1 += $('#mf123_select_jahr').val()[i];
}
var postedData1 = {};
postedData1.years1 = years1;
console.log(postedData1);
$.ajax({
url: "data/json.dashboard.php?call=chart2",
data: postedData1,
dataType: 'json',
type: 'POST',
success: function (dataGraph2) {
var trHTML='';
$.each(dataGraph2, function (key, value) {
for (var i in postedData1) {
Jahr1.push(postedData1[i].years1);
}
console.log(postedData1.years1);
trHTML +=
'<tr><td >' + value.Mandant +
'</td><td >' + thousandSepNeu(value.Jahr1, 2) + " €" +
'</td><td >' + value.Growth +
'</td></tr>';
});
$('#dataGraph2').append(trHTML);
}
});
}
The value.Mandant and the value.Growth are doing well. The problem that I have is that the for loop does not work. I need to thr postedData1 to choose whenever the user choose the year to show him the results.
The output of console.log(postedData1); is:
Am I making a mistake? I know that the problem is on the for loop.
Please any advice i would appreciate it.

I have managed to print out one array but how to do print out all arrays as this is for forum.
$(document).ready(function() {
var comments = document.getElementById("allcomments").value;
//Get Storage
var username = window.localStorage.getItem("username");
// Call Ajax for existing comments
$.ajax({
type: 'GET',
url: 'URL',
success: function(result) {
var arr = JSON.parse(result);
for(var i = 0; i < arr.length; i++) {
var obj = arr[i];
console.log(obj);
var output = document.getElementById("allcomments");
output.innerHTML = (obj.username + ' ' + obj.comment + ' ' + obj.commDate + ' ' + obj.sentiment);
}
}
});
return false;
});
Since you're using jQuery, you should consider using the append() function instead of innerHTML. There are not a lot of valid use cases for innerHTML, you should try to avoid it.
I am using for loop get all the data place in a div. I have following code in javascript so far:
<script type="text/javascript">
function callback(){
$.getScript("/frontend/vendor/jquery/jquery.min.js", function() {
$('input').on('change', function(){
var qty = $(this).attr('id');
var price = $('#'+qty+'_price').attr('value');
var subtotal = qty * price;
$('#'+qty+'_total').html('€ '+subtotal);
})
});
}
function checkout(callback){
let eventDate = JSON.parse(localStorage.getItem("events"));
var unique = eventDate.filter(function(itm, i, eventDate) {
return i == eventDate.indexOf(itm);
});
let items = [];
for (var n = 0; n < unique.length; n++){
var eventId = unique[n];
$.ajax({
"url":"/get_my_product/"+ eventId,
"type":"GET",
"dataType":"json",
"contentType":"application/json",
success:function(response){
let party = 'Party name';
let html = "<tr class='product-row'><td class='product-col'><h5 class='product-title'><a>"+party+"</a></h5></td><td class='product-col'><h5 class='product-title'><a>"+response.date+"</a></h5></td><td value='"+response.price+"' id='"+n+"_price'>€ "+response.price+"</td><td><div class='input-group'><input class='vertical-quantity form-control dataqty' id='"+n+"' type='number'><span class='input-group-btn-vertical'></span></div></td><td id='"+n+"_total'>€ "+response.price+"</td></tr>";
$('#data').append(html);
}
})
}
callback && callback();
}
checkout();
</script>
When I am trying to call the function after the loop completion it does not work. What is wrong here?
Change
function checkout(callback){
to
function checkout() {
I think the argument callback to the function checkout "shadows" the previously defined callback function. Then, when you call the function checkout you are passing nothing to the function, and callback will be undefined.
Or, in the last line, pass the function as an argument:
checkout(callback);
Makes no sense to add another version of jQuery to add events. You are not passing the callback to the method so it is always going to be undefined. And you are not waiting for the Ajax calls to complete before calling the callback.
// No reason for loading the JQuery version here
function addMyEvents() {
$('input').on('change', function() {
var qty = $(this).attr('id');
var price = $('#' + qty + '_price').attr('value');
var subtotal = qty * price;
$('#' + qty + '_total').html('€ ' + subtotal);
})
}
function checkout(callback) {
// hold the ajax calls
const myAjaxCalls = []
let eventDate = JSON.parse(localStorage.getItem("events"));
var unique = eventDate.filter(function(itm, i, eventDate) {
return i == eventDate.indexOf(itm);
});
let items = [];
for (var n = 0; n < unique.length; n++) {
var eventId = unique[n];
// push the ajax calls to an array
myAjaxCalls.push($.ajax({
"url": "/get_my_product/" + eventId,
"type": "GET",
"dataType": "json",
"contentType": "application/json",
success: function(response) {
let party = 'Party name';
let html = "<tr class='product-row'><td class='product-col'><h5 class='product-title'><a>" + party + "</a></h5></td><td class='product-col'><h5 class='product-title'><a>" + response.date + "</a></h5></td><td value='" + response.price + "' id='" + n + "_price'>€ " + response.price + "</td><td><div class='input-group'><input class='vertical-quantity form-control dataqty' id='" + n + "' type='number'><span class='input-group-btn-vertical'></span></div></td><td id='" + n + "_total'>€ " + response.price + "</td></tr>";
$('#data').append(html);
}
}))
}
// if we have a callback
if (callback) {
// wait for all the ajax calls to be done
$.when.apply($, myAjaxCalls).done(callback)
}
}
// pass the function to the method.
checkout(addMyEvents);
Now the best part is you do not even need to worry about the callback to bind events. You can just use event delegation and it would work. This way whenever an input is added to the page, it will be picked up.
$(document).on('change', 'input', function() {
var qty = $(this).attr('id');
var price = $('#' + qty + '_price').attr('value');
var subtotal = qty * price;
$('#' + qty + '_total').html('€ ' + subtotal);
})
function checkout() {
let eventDate = JSON.parse(localStorage.getItem("events"));
var unique = eventDate.filter(function(itm, i, eventDate) {
return i == eventDate.indexOf(itm);
});
let items = [];
for (var n = 0; n < unique.length; n++) {
var eventId = unique[n];
$.ajax({
"url": "/get_my_product/" + eventId,
"type": "GET",
"dataType": "json",
"contentType": "application/json",
success: function(response) {
let party = 'Party name';
let html = "<tr class='product-row'><td class='product-col'><h5 class='product-title'><a>" + party + "</a></h5></td><td class='product-col'><h5 class='product-title'><a>" + response.date + "</a></h5></td><td value='" + response.price + "' id='" + n + "_price'>€ " + response.price + "</td><td><div class='input-group'><input class='vertical-quantity form-control dataqty' id='" + n + "' type='number'><span class='input-group-btn-vertical'></span></div></td><td id='" + n + "_total'>€ " + response.price + "</td></tr>";
$('#data').append(html);
}
})
}
}
checkout();
I have a javascript file here.What it does is,when a user selects seats accordings to his preference in a theater layout,the selected seats are stored in an array named "seat".This code works fine until function where the selected seats are shown in a window alert.But from there onwards,the code doesn't seem to do anything.
After the above window alert, I've tried to serialize the above array and send it to the "confirm.php" file.But it does not show anything when echoed the seats.
Here is the js code.
<script type="text/javascript">
$(function () {
var settings = {
rows: 6,
cols: 15,
rowCssPrefix: 'row-',
colCssPrefix: 'col-',
seatWidth: 80,
seatHeight: 80,
seatCss: 'seat',
selectedSeatCss: 'selectedSeat',
selectingSeatCss: 'selectingSeat'
};
var init = function (reservedSeat) {
var seat = [], seatNo, className;
for (i = 0; i < settings.rows; i++) {
for (j = 0; j < settings.cols; j++) {
seatNo = (i + j * settings.rows + 1);
className = settings.seatCss + ' ' + settings.rowCssPrefix + i.toString() + ' ' + settings.colCssPrefix + j.toString();
if ($.isArray(reservedSeat) && $.inArray(seatNo, reservedSeat) != -1) {
className += ' ' + settings.selectedSeatCss;
}
seat.push('<li class="' + className + '"' +
'style="top:' + (i * settings.seatHeight).toString() + 'px;left:' + (j * settings.seatWidth).toString() + 'px">' +
'<a title="' + seatNo + '">' + seatNo + '</a>' +
'</li>');
}
}
$('#place').html(seat.join(''));
};
var jArray = <?= json_encode($seats) ?>;
init(jArray);
$('.' + settings.seatCss).click(function () {
if ($(this).hasClass(settings.selectedSeatCss)) {
alert('This seat is already reserved!');
} else {
$(this).toggleClass(settings.selectingSeatCss);
}
});
$('#btnShowNew').click(function () {
var seat = [], item;
$.each($('#place li.' + settings.selectingSeatCss + ' a'), function (index, value) {
item = $(this).attr('title');
seat.push(item);
});
window.alert(seat);
});
$('#btnsubmit').click(function () {
var seat = [], item;
$.each($('#place li.' + settings.selectingSeatCss + ' a'), function (index, value) {
item = $(this).attr('title');
seat.push(item);
var seatar = JSON.stringify(seat);
$.ajax({
method: "POST",
url: "confirm.php",
data: {data: seatar}
});
});
});
});
</script>
Can somebody help me figure it out what's wrong in here?
Please Add content type as json.
$.ajax({
method: "POST",
url: "confirm.php",
contentType: "application/json"
data: {data: seatar}
});
For testing you can print file_get_contents('php://input') as this works regardless of content type.
I've been following this answer in an attempt to write good asynchronous js - but I can't quite figure out what's going wrong for me.
I'm using autocomplete to request a specific set of files from the server, but for some datasets these files may not exist (i.e, there may be one, or up to four files). If they do exist, I want to append .html to include them.
The images don't load unless I add
async: false
to the .ajax call, which makes the callback redundant.
for (var i = 1; i < 5; i++) {
(function (counter) {
// define function with the callback argument
function ajaxTest(callback) {
$.ajax({
type: "GET",
url: counter + "_1.jpg",
success: function (result) {
callback(counter);
}
});
}
// call the function
ajaxTest(function (num) {
var image_temp = '<div class="thumbnail"> <img class="img-thumbnail" src="'+ num + '_1.jpg" /> Image' + num + '</div>';
console.log(image_temp); //check readout
image_html += image_temp;
});
})(i);
}
Then image_html contains html for only those images that exist.
$('#outputcontent').html(outer_html + image_html + outer_html_end);
Can anyone explain to my misunderstanding here please? Why isn't image_html being populated?
EDIT: 'full' code below. I use jquery autocomplete to pull from the stellar_comp array, then for those with properties that exist (some are blank), html is generated. Within that is the ajax call.
$(function () {
var stellar_comp = [
{
value:'X0005-28',
data: {
set0: {
aperture:'X2105-28',
secat:'X025-18',
set:'1',
run:'r06',
continuumFilter:'J',
narrowBandFilter:'638/28',
numberOfSources:'1',
priorityCode:'1'
etc... etc ...
},
},
];
$('#autocomplete').autocomplete({
lookup: stellar_comp,
onSelect: function (suggestion) {
var path_Value = 'data/' + suggestion.value + '/';
var outer_html = '<h1>' + suggestion.value + ' </h1> <div class="container">';
var outer_html_end = '</div>';
for (var category in suggestion.data) {
if (suggestion.data.hasOwnProperty(category)) {
if (suggestion.data[category].aperture) {
summary_table_contents = '<tr> <td>' + suggestion.data[category].set + '</td> <td>' + suggestion.data[category].run + '</td> <td>' + suggestion.data[category].continuumFilter + '</td> <td>' + suggestion.data[category].narrowBandFilter + '</td> <td>' + suggestion.data[category].numberOfSources + '</td> <td>' + suggestion.data[category].priorityCode + '</td></tr> ';
summary_table += summary_table_contents;
var aperturePlot = suggestion.data[category].aperture + '_' + suggestion.data[category].run;
var seCATPlot = suggestion.data[category].secat + '_Rsub_ss_' + suggestion.data[category].run;
var aperture_match = suggestion.data[category].aperture_match;
cog = path_Plots + aperturePlot + '_cog';
sbprof = path_Plots + aperturePlot + '_sbprof';
thumb_cog = '';
thumb_cog_temp = '';
thumb_sb = '';
temp='';
for (var i = 1; i < 5; i++) {
(function (counter) {
function some_function(callback) {
$.ajax({
type: "GET",
url: cog + counter + "_1.jpg",
async: false,
success: function (result) {
callback(counter);
}
});
}
some_function(function (num) {
var thumb_cog_temp = '<div class="col-lg-3 col-sm-4 col-xs-6"> <a class="thumbnail" target="_blank" href="' + cog + num + '_1.jpg"> <img class="img-thumbnail" src="' + cog + num + '_4.jpg" /></a> <div class="caption"><h5>' + suggestion.value + ':S' + num + '</h5></div></div>';
var thumb_sb_temp = '<div class="col-lg-3 col-sm-4 col-xs-6"> <a class="thumbnail" target="_blank" href="' + sbprof + num + '_1.jpg"><img class="img-thumbnail" src="' + sbprof + num + '_4.jpg" /></a><div class="caption"><h5>' + suggestion.value + ':S' + num + ' </h5></div></div>';
console.log(num, counter);
thumb_cog += thumb_cog_temp;
thumb_sb += thumb_sb_temp;
});
})(i);
}
cog_sbprofile_row='<div class="row"><h3>C o G</h3> ' + thumb_cog + '</div><div class="row"><h3>Profiles</h3> ' + thumb_sb + '</div>';
console.log(cog_sbprofile_row);
body_html += aperture_row;
body_html += seCAT_row;
body_html += aperture_match_row;
body_html += pixel_map_row;
body_html += skyprofile_row;
body_html += cog_sbprofile_row;
body_html += '<hr>';
};
};
};
top_html += summary_table + '</tbody> </table> </div></div> <hr>';
$('#outputcontent').html(outer_html + hipass_container + top_html + body_html + outer_html_end);
}
});
});
The current problem is due to using the resulting HTML string, before it has been created via multiple asynchronous calls. You need to either defer that operation until all loads are completed, or change the situation so it is not dependent on final completion (progressive loading looks busier anyway).
Personally I would simply insert placeholders for the images as you loop and insert each as they load. This way the order is retained. You can even do effects (fade etc) on each as they load:
var wrapper = "";
for (var i = 1; i < 5; i++) {
// Make a placeholder element for each image we expect
wrapper += '<div class="thumbnail" id="thumb_' + i + '">'
(function (num) {
// call the function
$.ajax({
type: "GET",
url: num + "_1.jpg",
success: function (result) {
var image_temp = '<img class="img-thumbnail" src="'+ num + '_1.jpg" /> Image' + num;
// Insert new image into unique element and fade it in
$('#thumb_'+num).append(image_temp).fadeIn();
}
});
})(i);
}
// Append all placeholders immediately - these will be appended to as each image is loaded
$('#outputcontent').html(outer_html + wrappers + outer_html_end);
Update:
As Alnitak points out, the whole exercise is a little pointless as you are ignoring the result returned from the Ajax call anyway, so you might as well drop the Ajax call (which adds no value) and simply build the image elements on the fly server-side :)
You have to do the appending after all ajax requests finish their jobs. First define this:
var after = function(reqs) {
var d = $.Deferred(),
cnt = reqs.length;
if (!cnt) {
d.resolve();
}
var limit = cnt; // separate var just in case reqs are synchronous
// so it won't mess up the loop
for (var i = 0; i < limit; i++) {
reqs[i].always(function() {
cnt--;
if (!cnt) {
d.resolve();
}
});
}
return d.promise();
};
You can use $.when instead of this but if one of the requests results in 404 it won't wait for others. Now:
var image_html = "",
requests = [];
for (var i = 1; i < 5; i++) {
(function (counter) {
// define function with the callback argument
function ajaxTest(callback) {
return $.ajax({
type: "GET",
url: counter + "_1.jpg",
success: function (result) {
callback(counter);
}
});
}
// call the function
var req = ajaxTest(function (num) {
var image_temp = '<div class="thumbnail"> <img class="img-thumbnail" src="'+ num + '_1.jpg" /> Image' + num + '</div>';
console.log(image_temp); //check readout
image_html += image_temp;
});
requests.push(req); // push the request to the array
})(i);
}
after(requests).done(function() {
$('#outputcontent').html(outer_html + image_html + outer_html_end);
});
Note that I've added return $.ajax(...).
BTW: what's the point of defining ajaxTest function? Just put everything in an anonymous callback.
Read more about deferred objects and promises here:
http://api.jquery.com/category/deferred-object/
http://joseoncode.com/2011/09/26/a-walkthrough-jquery-deferred-and-promise/
or just google it.
EDIT: if the order is important then you just have to tweak the callback function a bit:
var image_html = []; // array instead of string
// some code...
var req = ajaxTest(function (num) {
// ...
image_html[counter] = image_temp;
});
// some code...
after(requests).done(function() {
image_html = image_html.join("");
$('#outputcontent').html(outer_html + image_html + outer_html_end);
});
Let suppose i have a json file
and i can read this file in my script like this
$(document).ready(function () {
$.ajax({
type: "GET",
url: "Package.html",
dataType: "json",
success: function (data) {
var t = '';
for (var i = 0; i < data.yearData.length; i++) {
var mainStoryTitle = data.yearData[i].players;
for (var j = 0; j < mainStoryTitle.length; j++) {
var storyTitle = mainStoryTitle[j].name;
var topStoryContent = mainStoryTitle[j].description;
var storyImage = mainStoryTitle[j].image;
t = t + '<div class="content">';
t = t + '<article class="topcontent">';
t = t + '<header class="top" id="top1"><h2>' + storyTitle + '</h2></header>';
t = t + '<header class="bottom">';
t = t + '<h6><img src="' + storyImage + '" height=150 width=200>' + '</h6></header>';
t = t + '<content class="hide" id="content_' + j + '"><p>' + topStoryContent + '</p></content>';
t = t + '</article>';
t = t + '</div>';
}
}
$(".content").html(t);
},
error: function (e, ts, et) { alert(ts) }
})
});
and then i put this script in my html file.
So when i run this, it works properly but the problem is when i click on view source then inside it shows the path of json instead of exact data.
Hope you got the problem and please revert me asap.thanx
Instead of using alert, use console.log(ts) this will post the JSON file into your console. From there you can easily look around and see the JSON file by clicking the down arrow.
console.log(data); shows as:
> Object {Data: Array[2], ResponseMessage: "", Success: true}
console.log(JSON.stringify(data)); shows as:
{"Data":[{"ControllerID":2,"Description":"Aeon Power Monitor","DevType":1,"ID":1,"Name":"Power Monitor"},{"ControllerID":2,"Description":"Aeon Power Switch","DevType":2,"ID":2,"Name":"Switch"}],"ResponseMessage":"","Success":true}
