This is driving me freaking BATTY as hell.
This is essentially what I am trying to accomplish.
You'll see the Json there are a 2 different departments "Office" and "Stockroom"
What I am trying to accomplish is to arrange everyone by the department they are in. The problem with this is that the HTML needs to look something like this
<h3>Section 1</h3>
<div>
<p>
First Paragraph
</p>
<p>
Second Paragraph
</p>
<p>
Third Paragraph
</p>
</div>
But unfortunately I cannot seem to get the </div> tag in the right spot at the end of the last paragraph of each section

You might want to change this to a jquery each loop and work with json objects directly inside it. The reason you were getting an accordion level each time was due to your loop inserting a h3 every time. I've supplied code to get you pretty much what you need.
edit:
Here is a link to my forked jsfiddle => http://jsfiddle.net/TTV6d/12/
Hope this helps
var departmentlist=new Array();
$.each(contacts, function(i,contact) {
//insert the departments
if (contact.department != null && $('#' + contact.department).length == 0) {
$('#accordion').append('<h3 id='+ contact.department +'>' + contact.department + '</h3>');
departmentlist.push(contact.department);
}
//insert contacts in the accordion
$('#' + contact.department).after('<p>' + contact.displayname + '</p>');
});
$.each(departmentlist, function(i,list) {
$("#" + list).nextUntil("h3").wrapAll("<div></div>");
});
First, be aware that browsers will generally attempt to normalize markup appended to the document: (http://jsfiddle.net/EVjaq/)
$('#container').append('<div><p>Testing</p>'); // no `</div>`
console.log($('#container').html()); // `<div><p>Testing</p></div>`
So, the open <div> in this line will be closed at the end for you, before the next <p> is appended:
$('#accordion').append('<div><p>' + contacts[i].displayname + '</p>');
To avoid this, you can store all of the HTML in a variable, concatenating segments together, and append it to the DOM only once it's done. Or, you can store the <div> and append to that, which can make the conditionals a bit simpler:
var lastvalue = null,
lastdiv = null;
for (var i = 0; i <= contacts.length - 1; i++) {
if (contacts[i].department != null) {
if (lastvalue != contacts[i].department) {
$('#accordion').append('<h3>' + contacts[i].department + '</h3>');
// remember `<div>`
lastdiv = $('<div>').appendTo('#accordion');
}
// append to the `<div>` directly rather than `#accordion`
// also, skip the `else` so you don't have to type this twice
lastdiv.append('<p>' + contacts[i].displayname + '</p>');
lastvalue = contacts[i].department;
r++;
}
}

What is the problem here?Thanks in advance
There are several problems in your code. I have modified your code into a plunkr here You should visit the working plnkr to find what was corrected however I will put some snippets here also.
The line below does not do anything.
var myData = JSON.parse(JSON.stringify(url.responseText || null, function(data){
The actual ajax call was missing so I added it
$.ajax({
url: url
}).done(function(myData){
//your code here
}
Then the loop
html = 'Nombre: ' + data[team].producto.nombre + '[\n]';
Here data is an array so it needs to be treated as an array. Further each array item itself is producto.
So this is corrected to
for (var i = 0; i < data.length ; i++) {
var producto = data[i];
var html = []; //variable html
html = '<div class="item"><b>Nombre: </b>' + producto.nombre + '<br/>[\n]';
html += '<b>Precio: $</b>' + producto.precio + '<br/>'; //precio
html += '<b>Marca: </b>' + producto.marca + '<br/>';
html += '<b>Presentación: </b>' + producto.presentacion + '<br/>';
html += '<b>Contenido: </b>' + producto.contenido + '<br/></div>';
$("#div1").append(html);
}
There are several issues:
url.responseText is undefined, and so the error complains on the first character of that, i.e. the u of undefined. Look at how you defined url and notice how that does no have responseText.
There is no Ajax call in your code. Use $.getJSON for this.
Do not use JSON.parse nor JSON.stringify: they only make things worse. jQuery will have done the conversion for you already.
If html is supposed to be a string, then don't initialise it as an array with [].
the onclick attribute references a function block that is not in the global scope.
Either add a click handler via code, or via the onclick attribute, but not both. So combine the code in one single click handler via one method.
The property producto does not exist in your JSON, so all the references to it will fail. Remove that property from your code, unless your JSON is different from what you have in the question
Other remarks:
You mix jQuery and non-jQuery syntax. When you have jQuery, use it. So not document.getElementById().
[\n] is a strange thing to output. I would remove that.
The loop for (var team in data) can be written with of instead of in, that way team will be the object, not the index, which makes the rest of your code simpler.
A button element doesn't need a type="button" attribute
Here is code that corrects all these issues:
HTML:
<div>
<div>Prueba basica de archivos</div>
<div id="div1"></div>
<button id="btn1">Team location</button>
</div>
JavaScript:
$(document).ready(function (){
$("#btn1").click(function(){
$(this).disabled = true;
$.ajaxSetup({ cache: false });
$.getJSON("productos.json").done(function(data) {
for (var team of data) {
$("#div1").append(
$('<div>').addClass('item').append([
$('<b>').text('Nombre'), team.nombre, $('<br>'),
$('<b>').text('Precio: $'), team.precio, $('<br>'),
$('<b>').text('Marca: '), team.marca, $('<br>'),
$('<b>').text('Presentación: '), team.presentacion, $('<br>'),
$('<b>').text('Contenido: '), team.contenido, $('<br/>')
])
);
}
});
});
});
I have a textarea that will contains a code entered by user and I want to get that code and scan it with jQuery to get the value inside a custom tag called setting then add this value to an input so the user will be able to change the value inside setting tag without touching the code. I was able to get the values and add them inside the inputs but I couldn't update the code with the new values.
HTML CODE :
<div id='tab-1'>
<textarea id='template-code' cols='67' rows='27'></textarea>
<button id='submit-code'>Submit Code</button>
</div>
<div id='tab-2' class='unactive'>
<form id='settings-form' method='POST'>
<div id='result'></div>
<button id='update-code'>Update Code</button>
</form>
</div>
CSS CODE :
.unactive {
display: none
}
jQuery CODE :
$('#template-code').change(function (){
var $that = $(this),
template_code = $that.val(),
code = '',
new_data = '',
text = '',
newCode = '';
// Extract settings from the theme and add them to #result
$(document).on('click', '#submit-code', function (){
$('#tab-1').addClass('unactive');
$('#tab-2').removeClass('unactive');
$(template_code).find('setting').each(function (i){
var $this = $(this),
setting_std = $this.text(),
setting_id = $this.attr('id');
code += '<input id="'+setting_id+'" name="'+setting_id+'" type="text" value="'+setting_std+'"><br>';
});
if(code !== ''){
$('#result').html(code);
}
});
// Update old data with the new one
$(document).on('click', '#update-code', function (){
new_data = $( "#settings-form" ).serializeArray();
$.each( new_data, function( i, new_field ) {
var start_key = "id='"+new_field.name+"'>",
end_key = '</setting>',
start = template_code.indexOf(start_key),
end = template_code.indexOf(end_key);
text = template_code.substring(start + start_key.length, end);
// THE PROBLEM IS HERE
// I want the variable template_code to contains the new value not the old one so I used replace but it seems that it doesn't work
template_code.replace(text, new_field.value);
});
$('#template-code').val(template_code);
$('#tab-1').removeClass('unactive');
return false;
});
});
This is an example of the theme code that will be added inside the textarea :

</div>
</head>
<body>

</html>
To understand my issue please enter to this JsFiddle and copy the code above then put it inside the textarea and click submit code, you will get two inputs the content of those inputs come from these two tags :
<setting id='post_thumbnail'>http://lorempixel.com/640/300/</setting>
<setting id='search_icon'>on</setting>
I want when the user change the value of inputs and click "update code" to change the value of setting tag inside the entire code.
Try this and see if it's what you're looking for:
HTML
<div id='tab-1'>
<textarea id='template' cols='67' rows='27'></textarea>
<button id='submit'>Submit Code</button>
</div>
<div id='tab-2'>
<form id='settings-form' method='POST'>
<div id='result'></div>
<button id='update'>Update Code</button>
</form>
</div>
JavaScript:

return string;
}
$("#submit").on('click', function() {
var virtual = document.createElement("div");
var temp = '';
virtual.innerHTML = $("#template").val();
$(virtual).find('setting').each(function(i) {
var $this = $(this),
setting_std = $this.text(),
setting_id = $this.attr('id');
temp += '<input id="' + setting_id + '" name="' + setting_id + '" type="text" value="' + setting_std + '"><br>';
});
if (temp !== '')
$('#result').html(temp);
});
$("#update").on('click', function(event) {
var temp = [];
event.preventDefault();
$("#result").find("input").each(function() {
temp.push("<setting id=\"" + this.id.toString() + "\">" + this.value.toString() + "</setting>");
});
$("#template").val(wrap(temp));
});
I believe that does what you're looking for? Even though you're using jQuery, I think you ended up making it a lot harder than it had to be. I used a virtual node to quickly/easily find and pull ONLY the setting tag from the textarea on submit (down and dirty, I suppose?).
I removed the styles and whatnot since it was interfering with rapid testing, and you'll need to apply proper sanity checking/validation against user input.
Edit: Updated answer to include a ghetto wrapping function to elucidate the concept. I would not recommend using it as is, but instead utilizing a real template, which would require work outside the scope of this question.
Most recent JSFiddle after editing: http://jsfiddle.net/zo3hh2ye/6/
Here's another version of the code. I saved the new values in an array and then replaced them with the existing values in the textarea text. Give a try and see if that solves your problem.
Script :
<script type="text/javascript">
$('#template-code').change(function () {
var $that = $(this),
template_code = $that.val(),
code = '',
new_data = '',
text = '',
newCode = '';
// Extract settings from the theme and add them to #result
$('#submit-code').click(function () {
$('#tab-1').addClass('unactive');
$('#tab-2').removeClass('unactive');
$(template_code).find('setting').each(function (i) {
var $this = $(this),
setting_std = $this.text(),
setting_id = $this.attr('id');
code += '<input id="' + setting_id + '" name="' + setting_id + '" type="text" value="' + setting_std + '"><br>';
});
if (code !== '') {
$('#result').html(code);
}
});
// Update old data with the new one
$('#update-code').click(function () {
new_data = $("#settings-form").serializeArray();
$(template_code).find('setting').each(function (i) {
template_code = template_code.replace("<setting", "").replace("id='" + $(this).attr("id") + "'>", "").replace($(this).html(), "{" + i + "}").replace("</setting>", "");
});
$.each(new_data, function (i, new_field) {
template_code = template_code.replace("{" + i + "}", "<setting id='" + new_field.name + "'>" + new_field.value + "</setting>");
});
$('#template-code').val(template_code);
$('#tab-1').removeClass('unactive');
return false;
});
});
</script>

I couldn't replace the text 'on' in the template you provided, not sure if it has something to do with some reserved key word but everything else works fine.
I am making a search feature, that searches through a JSON object and finds the person you are looking for and displays some information about them, but for now it only works if you search for either the first name of the person or the last name separately. I want the search to be able to find the person even if I type both the first name and the last name in the same text field.

Turn your logic around inside the filter.

I wrote the following code:

</head>
<body>
<style>

function loadData() {
$.getJSON('data.json', function(data) {

document.title= 'State 1:' + " " + initial + " " + "and" + " " + "State 2:" + " " + initialSecond;
}
$('#placeholder').change(function() {

});
});

}
</script>

</html>
It's purpose is to simply update every 800 milliseconds and update the results on the page. It works.
The problem is that I want a simple alert whenever either of the state of the two items changes, saying which product ID change from which state to which state.
I can't even seem to be able to get the alert first, not even mentioning telling it which product changed and from what state to what state.
Why isn't my alert working? The jQuery documentation state that this... this should be functional.
EDIT:
Solved with the help of blunderboy's solution below.
Here's how it ended-up looking:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8" />
<title>JSON On-change Sample</title>

}
h3, h4 {
margin-bottom: 15px;
text-align: center;
}
</style>
<h3>The numbers represent the state of the two products. Get the alert and the update via AJAX by changing the state data in the data.json file and saving it.</h3>
<h4> Product 1: </h4>

<div id="placeholderTwo"></div>
<script src="http://code.jquery.com/jquery-1.7.1.min.js"></script>
<script>
$(document).ready(function(){
//DOCUMENT READY FUNCTION
loadData();
});
function loadData() {
$.getJSON('data.json', function(data) {
var output = data.response.items[0].state;
var outputTwo = data.response.items[1].state;
// Cache the initialState before putting updated value in it
var initialStateOne = document.getElementById("placeholderOne").innerHTML;
var initialStateTwo = document.getElementById("placeholderTwo").innerHTML;
document.getElementById("placeholderOne").innerHTML=output;

}
};
});

}
</script>

</html>
Check out jQuery Change Event API. It clearly says change event is limited to textarea, select and input. That's why you can not get this working.
Instead you could compare previous and the latest values manually and alert your change event.
Your code will look like this:
function loadData() {
$.getJSON('data.json', function(data) {
var output="<span>";
output+= data.response.items[0].state;
output+= data.response.items[1].state;
output+="</span>";
// Cache the initialState before putting updated value in it
var initialState = document.getElementById("placeholder").innerHTML;
document.getElementById("placeholder").innerHTML=output;
var initial = (data.response.items[0].state);
var initialSecond = (data.response.items[1].state);
if (initial > 0 || initialSecond > 0) {
document.title= 'State 1:' + " " + initial + " " + "and" + " " + "State 2:" + " " + initialSecond;
}
if (initialState != output) { //See this is the only change
alert("Changed!");
};
});
setTimeout("loadData()",800);
Here is another answer to your problem. You can use DOM Mutation Event: DOMSubtreeModified to figure out the changes in the subtree of an element. Here is JSbin Demo
HTML
<div id='a'></div>
JS
var $a = $('#a');
$a.on('DOMSubtreeModified', function() {
alert('Changed');
});
$a.html('This is test1');
$a.html('This is test2');
PS: Please note that this method will also call the event handler when you change any element inside this div. So you better remove this event handler when no longer required or handle such cases gracefully.
I've put together a little app using Kendo UI that stores user inputs in a Javascript array, and then prints these items out by adding text to a div. Along with the text, I need to have a delete button to remove these items from the array.
Since I'm adding the delete buttons to the DOM after I initialize Kendo UI, I assume I need to use the .kendoMobileButton() method on each button I add. If I don't do this, my buttons aren't styled correctly, despite being given the attribute data-role="button".
Still, when I try to use these buttons, I can't get them to call a function with data-click="deleteNumber". The function simply doesn't seem to fire. Any hints?
Here is a quick example I threw together that illustrates my problem: http://crocdoc.ifas.ufl.edu/files/kendo_example/
It is pasted here for easy reference:

<div id="number_list" style="padding: 0 20px 0 20px;"></div>
</div>
<script>
var app = new kendo.mobile.Application();
var number_container = [];
var addNumber = function () {
var current_number = Math.floor(Math.random() * 1000 + 1);
number_container.push(current_number);
console.log(number_container);
var current_index = number_container.length - 1;
$('#number_list').append('Number ' + current_index + ': ' + current_number + ' <a id="delete_' + current_index + '" data-role="button" data-click="deleteNumber">Delete</a><br >');
$('#delete_'+current_index).kendoMobileButton();
};
var deleteNumber = function (e) {
console.log('Delete button hit');
var button_id = e.button.context.id;
button_id = button_id.replace('delete_', '');
button_id = parseFloat(button_id);
number_container.splice(button_id, 1);
$('#number_list').empty();
for (var i = 0; i < number_container.length; i++) {
$('#number_list').append('Number '+i+': '+number_container[i]+' <a id="delete_' + i + '" data-role="button" data-click="deleteNumber">Delete</a><br >');
}
};
</script>
</body>
</html>
You need to modify your code as following ,
$('#number_list').append('Number ' + current_index + ': ' + current_number + ' <a id="delete_' + current_index + '">Delete</a><br/>');
$('#delete_'+current_index).kendoMobileButton({click: deleteNumber});
