How to access and use multiple data from json object? Do I need to make an array?

I am a beginner and using $.get to retrieve data from a rest API such as:
[{"id":"1","url":"http:\/\/123.456.78.910\/workforce\/images\/item1.jpg","price":"99","description":"Mobile Phone"},
{"id":"2","url":"http:\/\/123.456.78.910\/workforce\/images\/item2.jpg","price":"98","description":"Laptop"}
{"id":"3","url":"http:\/\/123.456.78.910\/workforce\/images\/item3.jpg","price":"92","description":"Console"}] }
$.get('http://xxxxxxxxxxx,
function (data) {
var obj = $.parseJSON(data);
So from what I understand I have retrieved the data from the REST API and parsed it so it is stored in a variable called obj.
My question is, how do I access and use each unique record in the obj variable?
Each record has it's own picture (item1.jpg, item2.jpg etc).
Whem my app loads I want it to show the item1.jpg image, and I want to be able to navigate to the other item pictures using buttons (previous / next).
I also want the description and price to be displayed underneath in some text input fields.
What I have figured so far is that I should:
Iterate through the obj variable, and store each record into an array.
Upon app initialisation I can set the default value for the image placeholder to array[index0].url, and set the description and price fields.
I can then set the previous and next buttons to array[currentIndex-1] or array[currentIndex+1].
Would this be the best way to do it?
Or can I just do this without using an array and manipulate the obj.data directly?
Thanks!!!

I may not be understanding what exactly what you want to do but I think I have the gist. If you just want to show the picture then the array of just images probably wouldn't be a bad idea. However, it looks like the Jason you're getting is already in an array. You can just use array index notation to get to what you want.
ie)
var arr = //your json response ;
var current = 0; //sets currently displayed object to the first in the array
var setCurrent = function () {
var image = arr[current]["url"];
}
You can then modify current however you want (on click on arrow iterate up/down, etc) then call the setCurrent function to set your image the the one you want. Hope that helps!

You can use the response you have from $.get() directly.
It is an array of objects.
You can use it like this:
console.log(data[2].description);
// outputs: "Console"
I've made a CodePen demo where it has a 4th object with a real image url to show you how to use the url info...
EDIT
Just in case you wouldn't know this:
You can use the response inside the scope of the $.get() callback...
You can not use it straith after the $.get() outside the callback since $.get() is asynchronous.
You can use it in some other handler wich will happen after the response is received.
var getResponse;
$.get('http://xxxxxxxxxxx', function (data) {
getResponse = data;
console.log(data[2].description);
// outputs: "Console"
console.log(getResponse[2].description);
// outputs: "Console"
});
console.log(getResponse[2].description);
// outputs: "Undefined"
// But since this handler will be triggered long after the response is obtained:
$("#somebutton").click(function(){
console.log(getResponse[2].description);
// outputs: "console"
});

In order for your page javascript to be able to access the data retrieved from your ajax request, you'll need to assign it to some variable which exists outside the callback function.
You will need to wait until the ajax request has been processed before you can read the array. So you might want to set the actual default image to be something that doesn't rely on the ajax request (a local image).
Here's a simple approach
// fake testing ajax func
function fakeget (url, callback) {
setTimeout(callback(JSON.stringify([
{"id":"1","url":"http:\/\/123.456.78.910\/workforce\/images\/item1.jpg","price":"99","description":"Mobile Phone"}, {"id":"2","url":"http:\/\/123.456.78.910\/workforce\/images\/item2.jpg","price":"98","description":"Laptop"},
{"id":"3","url":"http:\/\/123.456.78.910\/workforce\/images\/item3.jpg","price":"92","description":"Console"}
])), 1000);
}
// real code starts here
// global variables for ajax callback and setImg func to update
var imageData, currentImg;
// change this back to $.get for real
fakeget('http://xxxxxxxxxxx',
function (data) {
imageData = $.parseJSON(data);
setImg(0);
}
);
function setImg(index) {
// turns negative indices into expected "wraparound" index
currentImg = (index % imageData.length + imageData.length) % imageData.length;
var r = imageData[currentImg];
$("#theImg").attr('src', r.url);
$('#theDescription').text(r.price + " " + r.description);
}
$("#prev").click(function () {
setImg(currentImg - 1);
});
$("#next").click(function () {
setImg(currentImg + 1);
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div>
<img id='theImg' src='somedefault.jpg'>
<div id='theDescription'></div>
</div>
<button id='prev'>Prev</button>
<button id='next'>Next</button>

Few observations :
Your JSON Object is not a valid JSON.
No need to parse it again your data is already a JSON Object.
Working fiddle
var data = [{"id":"1","url":"http:\/\/123.456.78.910\/workforce\/images\/item1.jpg","price":"99","description":"Mobile Phone"},{"id":"2","url":"http:\/\/123.456.78.910\/workforce\/images\/item2.jpg","price":"98","description":"Laptop"}, {"id":"3","url":"http:\/\/123.456.78.910\/workforce\/images\/item3.jpg","price":"92","description":"Console"}];
for (var i in data) {
var imgUrl = data[i].url;
console.log(imgUrl);
}

Json data from table in an onclick function show in seperate div

I'm trying to get data used in my table to be used in a div when I click on the table. The thing is, there are multiple tables in my script according to the data of my JSON. So my JSON consists of object that consists of object. For example:
My table(s) are rendered like this:
data.forEach(function(somedata){
return '<table><tr><td>'+somedata.something+'</td></tr></table>';
});
Now I've tried to get the onclick to work in this case but I cant seem to figure out how. I'd like to not use specific ID's rendered in the foreach like:
var i=0;
data.forEach(function(somedata){
i++;
return '<table id="'.id.'"><tr><td>'+somedata.something+'</td></tr></table>';
});
the variable somedata consists of an object so I cant just make an onclick in the html code of the table either and send the data in it.
So somedata would look something like this but json encoded:
somedata{
[0]=>array(
'something'=>'test',
'theobject'=>array(...)
),
[1]=>array(etc...)
}
Now what I want is to get the data from theobject in a seperate div as soon as I click on the table that belongs to the right somedata.
I've been thinking of making a jquery on click for this but then I would need specific ID's in the table(if that's the only possible solution then I'd take it). Cant I do something with this or something? Or send the data at the same time it's being rendered cause in my code I can at the moment of course reach to somedata.theobject
I think I'm thinking a bit too difficult about this. Am I?

You can pass this in onclick function like
return '<table onclick=makeObject(this)><tr><td>'+somedata.something+'</td></tr></table>';
And then use the function to get the data
function makeObject(that){
var tbl = $(that).find('tr').map(function() {
return $(this).find('td').map(function() {
return $(this).html();
}).get();
}).get();
}

There are a few ways to go about this. Rather than using the forEach function we can use the jQuery.map function, since you've indicated that you're open to using jQuery :-)
var $els = $.map(data, function(somedata, i){
var $el = $('<table><tr><td>'+somedata.something+'</td></tr></table>')
.click(function(e) {
populateDivWithData(somedata.theobject);
});
return $el;
});
The call to .click inside each will create a separate click handler for each item in data; each click handler then has access to the relevant theobject value.
EDIT: Thanks #Loko for the reminder about the .forEach built-in

Find and manipulate a HTML DIV element that is stored in a variable, using jQuery

I've been searching for a few hours to try and find a solution to my issue, for some reason partially similar answers on here don't seem to be working for me - so I'm creating my own question.
Basically, I'm loading pre-rendered HTML from the server using jQuery's $.get method, and I need to split the HTML returned into two sections (one that's wrapped in a div called #section-one and the other simply alongside that div, with no parent element).
See the example below:
$.get('http://jamie.st/remote_file.php', function(data){
// I want to get '#section-one' and then remove it from data, basically splitting a single returned HTML resource into two, that can be placed in two different areas of the page.
var sectionOne = $(data).find('#section-one');
// This should only return the HTML of '#section-one'
console.log(sectionOne);
// Also how can I then remove '#section-one' from the 'data' variable? The equivalent of calling the below, but from the 'data' variables string/html.
$(sectionOne).remove();
// So eventually the below would return the HTML without the '#section-one' element (and it's children)
console.log(data);
});
I've also created a jsfiddle which you can play around with if you need to, it's set up to use a real PHP file that I've hosted for demo purposes.
http://jsfiddle.net/6p0spp23/6/
If you can submit a jsfiddle link back that would be much appreciated, thanks in advance guys!

When you create a jQuery object with the remote contents $(data) becomes a collection of elements so instead of find() you want to use filter() like so:
$.get('http://jamie.st/remote_file.php', function(data){
var $data = $(data),
$sectionOne = $data.filter('#section-one'),
$rest = $data.filter(':not(#section-one)');
console.log($sectionOne);
console.log($rest);
});
Demo fiddle

I think the best way to put the received data inside a parent div. Then you can call remove or any other method to use it.
You can make parent div hidden using .hide() method if you don't want to show it.
Here I did it:
http://plnkr.co/edit/jQKXyles8sP8dliB7v0K?p=preview
// Add your javascript here
$(function() {
$.get('http://jamie.st/remote_file.php', function(data) {
$("#parent").hide();
$("#parent").html(data);
$("#section-one").remove();
console.log($("#section-one").html())
alert($("#parent").html())
});
});

When you remove a subsection from a derived jQuery object, the original string is not updated with the change so if you want the updated html content you need to generate it from the jQuery object. One way to do this is to
$.get('http://jamie.st/remote_file.php', function (data) {
var $ct = $('<div />', {
html: data
});
// I want to get '#section-one' and then remove it from data, basically splitting a single returned HTML resource into two, that can be placed in two different areas of the page.
var sectionOne = $ct.find('#section-one');
// This should only return the HTML of '#section-one'
console.log(sectionOne);
// Also how can I then remove '#section-one' from the 'data' variable? The equivilant of calling the below, but from the 'data' variables string/html.
$(sectionOne).remove();
// So eventually the below would return the HTML without the '#section-one' element (and it's children)
console.log($ct.html());
});
Demo: Fiddle

Get input value and insert into table on different page

How would I do the question asked above. I have tried .append() in javascript but can you get data from one html file and insert it into another?? Some please help.

If the page you are receiving the data was created by your js then do it like this.
var childPage = window.open("somepage.html");
The child page would need a global function to receive data, then just call it.
childPage.passData(dataToPass);
If the page to receive the data is the parent, and the input is on the child do like this.
window.parent.someFunction(dataToPass);
Your respective functions would then have to take said data and do the work fro there.
the functions do have to be on the global scope of each page.

Your should wrap the inputs in a<form> whose action attribute is set to the url of the page in which you want to display the values, as shown below:
<form action='url to second page' method='get'>
<input name='name' value='something' />
<button>Submit</button>
</form>
In the second html page, You can retrieve the request parameters by calling the js function given in this answer when it is loaded:
For example,
<html>
<head>
<title>b.html</title>
<script>
function load() {
var params = getRequests();
console.log(params['name']);
}
function getRequests() {
var s1 = location.search.substring(1, location.search.length).split('&'),
r = {}, s2, i;
for (i = 0; i < s1.length; i += 1) {
s2 = s1[i].split('=');
r[decodeURIComponent(s2[0]).toLowerCase()] = decodeURIComponent(s2[1]);
}
return r;
};
</script>
</head>
<body onload='load();'></body>
</html>
The function getRequests() returns an object containing all request parameters with the name of input element as key value. So if your first html page contains an input with name='test', the following code :
var params= getRequests();
var value =params['name'];
will give you the value of test input in second html page. Then you can use DOM API methods such as document.getElementById() to target the table elements in which you want to display the value, and set it's innerText.

can you get data from one html file and insert it into another?
Try .load()
$("#mydivid").load("/myotherpage.html");
To get a specific part of that page
$("#mydivid").load("/myotherpage.html #dividonotherpage");
We can also do something after it has loaded
$("#mydivid").load("/myotherpage.html", function() {
$("#mydivid").show();
/* like grab the values of attributes .. */
});
https://api.jquery.com/load/
edit: / reading #QBM5, I see you might be referring to 'data' as local client side user input from another window. Disregard this answer if so, as this will not pick up changes that are not set as part of the original delivered markup.

How to update cached jquery object after adding elements via AJAX

I'm trying to write a plugin-like function in jQuery to add elements to a container with AJAX.
It looks like this:
$.fn.cacheload = function(index) {
var $this = $(this);
$.get("cache.php", {{ id: index }).done(function(data) {
// cache.php returns <div class='entry'>Content</div> ...
$(data).insertAfter($this.last());
});
}
and I would like to use it like this:
var entries = $("div.entry"),
id = 28;
entries.cacheload(id);
Think that this would load another "entry"-container and add it to the DOM.
This is works so far. But of course the variable that holds the cached jQuery object (entries) isn't updated. So if there were two divs in the beginning and you would add another with this function it would show in the DOM, but entries would still reference the original two divs only.
I know you can't use the return value of get because the AJAX-call is asynchronous. But is there any way to update the cached object so it contains the elements loaded via AJAX as well?
I know I could do it like this and re-query after inserting:
$.get("cache.php", {{ id: num }).done(function(data) {
$(data).insertAfter($this.last());
entries = $("div.entry");
});
but for this I would have to reference the variable holding the cached objects directly.
Is there any way around this so the function is self-contained?
I tried re-assigning $(this), but got an error. .add() doesn't update the cached object, it creates a new (temporary) object.
Thanks a lot!
// UPDATE:
John S gave a really good answer below. However, I ended up realizing that for me something else would actually work better.
Now the plugin function inserts a blank element (synchronously) and when the AJAX call is complete the attributes of that element are updated. That also ensures that elements are loaded in the correct order. For anyone stumbling over this, here is a JSFiddle: http://jsfiddle.net/JZsLt/2/

As you said yourself, the ajax call is asynchronous. Therefore, your plugin is asynchronous as as well. There's no way for your plugin to add the new elements to the jQuery object until the ajax call returns. Plus, as you discovered, you can't really add to the original jQuery object, you can only create a new jQuery object.
What you can do is have the plugin take a callback function as a second parameter. The callback could be passed a jQuery object that contains the original elements plus the newly inserted ones.
$.fn.cacheload = function(index, callback) {
var $this = this;
$.get('cache.php', { id: index }).done(function(html) {
var $elements = $(html);
$this.last().after($elements);
if (callback) {
callback.call($this, $this.add($elements));
}
});
return $this;
};
Then you could call:
entries.cacheload(id, function($newEntries) { doSomething($newEntries); } );
Of course, you could do this:
entries.cacheload(id, function($newEntries) { entries = $newEntries; } );
But entries will not be changed until the ajax call returns, so I don't see much value in it.
BTW: this inside a plugin refers to a jQuery object, so there's no need to call $(this).
