JSON to HTML not rendering into HTML via ID - javascript

I am using PHPstorm IDE and i'm trying to render the following JSON and it gets stuck showing only the <ul></ul> without spitting the <li>'s into HTML the each function. Any idea what could be the issue?
thanks.
Script.js:
$(function(){
$('#clickme').click(function (){
//fetch json file
$.ajax({
url:'data.json',
dataType: 'json',
success: function(data){
var items = [];
$.each(data, function (key, val) {
items.push('<li id=" ' + key + '">' + val + '</li>');
});
$('<ul/>', {
'class': 'tasks',
html: items.join('')
}).appendTo('body');
},
statusCode: {
404: function(){
alert('there was a problem with the server. try again in a few secs');
}
}
});
});
});
And the JSON:
{"id":"1","mesi":"mesima 0","done_bool":"1"},{"id":"2","mesi":"mesima 1","done_bool":"0"},{"id":"3","mesi":"mesima 2 ","done_bool":"1"},{"id":"4","mesi":"mesima 3","done_bool":"1"}
My HTML is just an a href that spits out the click ID:
Get JSON

<script>
$(document).ready(function(){
$("button").click(function(){
$.getJSON("demo_ajax_json.js", function(result){
$.each(result, function(i, field){
$("div").append(field + " ");
});
});
});
});
</script>
<button>Get JSON data</button>
By Using this Method You can Easily get Your JSON value In HTML

Try this one :)
$.ajax({
url: 'data.json',
dataType: 'json',
success: function(data){
var html = "<ul>";
items = data.map(function(obj){
html += "<li id='" + obj.id + "'>" + obj.mesi + "</li";
});
html += "</ul>";
$('body').append(html);

I would try with some like this
$(function(){
$('#clickme').click(function (){
//fetch json file
$.ajax({
url:'data.json',
dataType: 'json',
success: function(data){
// uncomment line below if data is a single JSON
// data = [data]
var items = [];
// we create a list where we will append the items
var list = document.createElement("ul");
data.forEach(function(item){
// we create a list item
var listItem = document.createElement("li");
// we set the attributes
listItem.setAttribute("id", item.id ); // item.id or the property that you need
// we add text to the item
listItem.textContent = item.mesi;
// We append the list item to the list
list.appendChild(listItem);
});
// we append the list to the body
$("body").html(list);
},
statusCode: {
404: function(){
alert('there was a problem with the server. try again in a few secs');
}
}
});
});
});

Try like this:
success: function(data){
var items = '';
$.each(data, function (key, val) {
items += '<li id=" ' + key + '">' + val + '</li>';
});
ul = $('<ul/>').html(items);
$('body').append(ul);
}
for multiple objects
success: function(datas){
var items = '';
$.each(datas, function (i,data) {
$.each(data, function (key, val) {
items += '<li id=" ' + key + '">' + val + '</li>';
});
});
ul = $('<ul/>').html(items);
$('body').append(ul);
}
output
<ul>
<li id=" id">1</li>
<li id=" mesi">mesima 0</li>
<li id=" done_bool">1</li>
<li id=" id">2</li>
<li id=" mesi">mesima 1</li>
.
.
</ul>

Try like this:
$(function() {
$('#clickme').click(function() {
// fetch json file
$.ajax({
url : 'data.json',
dataType : 'json',
// please confirm request type is GET/POST
type : 'GET',
success : function(data) {
// please check logs in browser console
console.log(data);
var ulHtml = "<ul>";
$.each(data, function(key, obj) {
ulHtml += '<li id="' + obj.id + '">' + obj.mesi + '</li>';
});
ulHtml += "</ul>";
// please check logs in browser console
console.log(ulHtml);
$('body').append(ulHtml);
},
error : function(jqXhr, textStatus, errorThrown) {
console.log(errorThrown);
alert(textStatus);
}
});
});
});
<button id="clickme">Get JSON data</button>
I log json data and created ul html, Please check logs in browser console

I'm not sure how you want to output each item, so I made a simple suggestion, you can easily change the HTML to what you need. Here is working code:
index.html
<!DOCTYPE html>
<html lang="en">
<head>
<script src="http://code.jquery.com/jquery-1.11.1.min.js"></script>
</head>
<body>
Get JSON
<script>
$(function() {
$('#clickme').click(function() {
//fetch json file
$.ajax({
url: 'data.json',
dataType: 'json',
success: function(data) {
var items = [];
$.each(data, function(key, val) {
// the HTML output for each item
var done = (val.done_bool === '1') ? 'true' : 'false';
items.push('<li id=" ' + val.id + '">' + val.mesi + ': ' + done + '</li>');
});
$('<ul/>', {
'class': 'tasks',
html: items.join('')
}).appendTo('body');
},
statusCode: {
404: function() {
alert('there was a problem with the server. try again in a few secs');
}
}
});
});
});
</script>
</body>
</html>
data.json
[{"id":"1","mesi":"mesima 0","done_bool":"1"},{"id":"2","mesi":"mesima 1","done_bool":"0"},{"id":"3","mesi":"mesima 2 ","done_bool":"1"},{"id":"4","mesi":"mesima 3","done_bool":"1"}]
I also created a __jsfiddle__ so you can test it directly. (The AJAX call is simulated with the Mockjax library): https://jsfiddle.net/dh60nn5g/
Good to know:
If you are trying to load the JSON from another domain, you may need to configure CORS (Cross-origin resource sharing):
https://en.wikipedia.org/wiki/Cross-origin_resource_sharing

Isn't this supposed to be a GET request? i think you are missing the method on your Ajax request. You should add
method: 'GET'
to your ajax request. I think this is a big deal in making ajax request.

Use jQuery to generate Thymeleaf

I'm trying to generate a Thyemeleaf from Json response:
$.ajax({
url: '/getJson',
success: function(data) {
$.each(data, function(i, obj) {
var htmlTag = "<span th:text='" + obj.name +
"'></span>";
$("#result").append(htmlTag);
});
}
});
But it doesn't render. Is it possible to generate html this way?

how to append a html tag from an ajax call response

I have an ajax function :
$('#app-name').change(function () {//1
console.log("inside change");
var applname= this.value;
console.log(applname);
$.ajax({//2
url: 'foo',
method : 'GET',
dataType : "json",
contentType: "application/json",
data: {"AppID":"appname"},
success: function(data){
var order_data = data;
$('#foo-name').html('');
$.each(order_data, function(i, item) {//3
console.log(order_data[i]);
$('<option value='+ order_data[i] +'>'+order_data[i]).html('</options>').appendTo('#foo-name');
});//3
}
});//2
});//1
This function is doing everything else except appending value to the html.
Am i doing it wrong? Can you help solve this issues.
Place the closing </option tag in the jQuery object you create. Don't set it through the html() method. Try this:
$('<option value="' + order_data[i] + '">' + order_data[i] + '</option>').appendTo('#foo-name');
That said, you can also improve performance of your code by building the string in the loop and appending it to the select once, like this:
success: function(data) {
var options = '';
$.each(data.split(/\n/), function(i, item) {
options += '<option value=' + item.trim() + '>' + item.trim() + '</option>');
});
$('#foo-name').html(options);
}
Update You also need to split() the text you state that you're returning before looping through it.
Please use below code in your ajax success event.
success: function(data) {
var _html = '';
$.each(order_data, function(i, item) {
_html += '<option value='+ item +'>'+item+'</options>';
});
$('#foo-name').append(_html);
}

Codeigniter Jquery Ajax: How to loop returned data as html

Im new to JQuery AJAX thing, this is my script:
$(document).ready(function() {
$("#city").change(function() {
var city_id = $("#city").val();
if (city_id != '') {
$.ajax({
type: "POST",
url: "<?php echo base_url() ?>index.php/home/get_block_by_id/" + city_id,
success: function(block_list) {
// WHAT TO PUT HERE ?
},
});
}
});
If i put console.log(block_list) it returns the right data with JSON type:
[{"id":"1601","id_city":"16","block":"A"},
{"id":"1602","id_city":"16","block":"B"}]
What is the correct way to loop the returned data? I did this to see what the loop returned:
$.each(block_list, function() {
$.each(this, function(index, val) {
console.log(index + '=' + val);
});
});
But it was totally messed up :(, if the looped data is correct I also want to put the id as a value and block name as a text for my <option> tag how to do that? thank you.
UPDATE
Sorry, I have try both answer and its not working, I try to change my code to this:
$("#city").change(function(){
var city_id = $("#city").val();
$.get("<?php echo base_url() ?>index.php/home/get_block_by_id/" + city_id, function(data) {
$.each(data, function(id, val) {
console.log(val.id);
});
});
});
it returns :
**UNDEFINED**
I also try to change it into val[id] or val['id'] still not working, help :(
$.each(block_list, function(id, block){
console.log('<option value="' + block['id'] + '">' + block['block'] + '</option>')
});
The output would be:
<option value="1601">A</option>
<option value="1602">B</option>
try something like:
success: function(data, textStatus, jqXHR) {
if (typeof(data)=='object'){
for (var i = 0; i < data.length; i++) {
console.log(data[i].id + ':' + data[i].id_city);
}
}
}
if ur json output is in this format
[{"id":"1601","id_city":"16","block":"A"},
{"id":"1602","id_city":"16","block":"B"}]
then
var city_id = $("#city").val();
if (city_id != '') {
$.ajax({
type: "POST",
url: "<?php echo base_url() ?>index.php/home/get_block_by_id/" + city_id,
success: function(data) {
$.each(data, function(index)
{
console.log(data[index]['id']);
$('#'+ddname+'')
.append($("<option></option>")
.text(data[index]['id']+"-"+data[index]['block']));
});
},
});
}

JQuery Adding elements to a list from parsed JSON

I am trying to parse some JSON and take the elements "startTime" and "endTime" and add them to a list. I am able to receive the JSON successfully, however I am having trouble properly parsing and then looping through to add each instance to the list. Inside of the UL, i would like to create lists for each, like i demo below:
$.ajax({
url: 'localhost:8080/sample?',
dataType: 'json',
success: function (data){
var json = $.parseJSON(data);
var $calAppts = $('#appts');
$('<li data-role="list-divider">' + this.startTime
+ ' - ' + this.endTime + '<span class="ui-li-count"></span></li>').appendTo($appts);
The HTML where I am trying to insert the LI inside of the UL:
<div data-role="main" class="ui-content" id="headerDate">
<ul data-role="listview" data-inset="true" id="appts">
</ul>
</div>
So basically for each appointment i get back in the JSON, I want to add a new LI with the startTime and endTime.
I am using JQM 1.3.2, and JQUERY 1.8.0.
Thank you
Change this:
$.ajax({
url: 'localhost:8080/sample?',
dataType: 'json',
success: function (data){
var json = $.parseJSON(data);
var $calAppts = $('#appts');
$('<li data-role="list-divider">' + this.startTime
+ ' - ' + this.endTime + '<span class="ui-li-count"></span></li>').appendTo($appts);
Into this:
$.ajax({
url: 'localhost:8080/sample?',
dataType: 'json',
success: function (data){
var json = $.parseJSON(data);
$.each( json, function( key, value ) {
var agrega = "<li data-role='list-divider'>";
if(key=='startTime')
{
agrega = agrega + value
}
if(key=='endTime')
{
agrega = agrega + ' - ' + value;
}
agrega = agrega + '<span class="ui-li-count"></span></li>';
$('#appts').append(agrega);
});
From your code sample, it seems your problem is that you're trying to look for the startTime property in the wrong place (on this). In your sample, the startTime property should be present on your parsed JSON, so accessing the key there should do the trick:
$('<li data-role="list-divider">' + json.startTime
+ ' - ' + json.endTime + '<span class="ui-li-count"></span></li>').appendTo($appts);
If the returned JSON is a series of times, then you'll also want to loop through the JSON object as well:
$.each(json, function(key, value) {
if (key === 'startTime') {
// append to the list
}
});
Additional note:
If JSON is what is being returned from the AJAX call, then you shouldn't need to use $.parseJSON on it. JSON objects are JavaScript objects, so you can simply use the returned value and access they keys on it (meaning you can use data.startTime directly instead of parsing it first).
Please find the response below
var ulObject = $("#appts");
var ajaxObject = $.ajax({
type:"POST",
dataType:"json",
url:"" //Provide the URL in the field to be processed.
});
ajaxObject.done(function(msg){
var jsonResponse = $.parseJSON(msg);
var listObjectStart = '<li data-role="list-divider">'
var listObjectEnd = '</li>';
$.each(jsonResponse,function(key,value){
if(key === "startTime")
{
listObjectStart += value;
}
else if(key === "endTime")
{
listObjectStart += '-'+value+'<span class="ui-li-count"></span>';
}
});
listObjectStart += listObjectEnd;
ulObject.append(listObjectStart);
});
Try the following if server send the data back to client in json format.
$.ajax({
url: 'localhost:8080/sample?',
dataType : 'json',
success: function(data){
$("#appts").append('<li data-role="list-divider">' + data.startTime
+ ' - ' + data.endTime + '<span class="ui-li-count"></span></li>');
},
error: function(){
alert('There was an error in communication.');
}
});

$.ajax() and "Uncaught ReferenceError: data is not defined"

I tried out several ways to get .json file and data using $.getJSON and $.ajax() overthere
My JS code n⁰2 fails :
$.ajax({
type: "GET",
url: 'js/main.js',
data: data,
success: 1,
}).done(function ( data ) {
var items = [];
$.each(data.tata.entities.q142.labels.fr.value, function(key, val) {
items.push('<li id="' + key + '">Test 2:' + val + '</li>');
});
$('<ul/>', {
'class': 'my-new-list',
html: items.join('')
}).appendTo('body');
});
In Chrome console, the message error is :
"Uncaught ReferenceError: data is not defined"
Refering to the line :
data: data,
What is going wrong ? What to do ?
Edit: all is done client side.
The problem is being caused because you didn't define the variable data, so try removing the data: data line, it looks like you're just getting a JavaScript file which wouldn't normally take a query string:
$.ajax({
type: "GET",
url: 'js/main.js',
success: success,
}).done(function ( data ) {
var items = [];
$.each(data.tata.entities.q142.labels.fr.value, function(key, val) {
items.push('<li id="' + key + '">Test 2:' + val + '</li>');
});
$('<ul/>', {
'class': 'my-new-list',
html: items.join('')
}).appendTo('body');
});
