how to process json data through an .each loop into html table
Question
I am making an ajax get request that displays json data in a html table. I know how to do this with javascript, so I thought I'd try it with jquery. There is a problem in my .each loop. I am vague on how the arguments (key, object) process more than one key value pair in each position and suspect this is where my error lies.
I have tried JSON.parse , but that didn't help. I am definitely getting the data as I can display it in an alert box. I suspect that what I'm doing is not industry standard and that there is a more elegant way to reach my objective.
$("#button").click(function(){
$.ajax({
type: 'get',
url: "http://www.adweb.agency/interview/api/animals",
data: {format: 'json' },
dataType: 'json',
success: function(data){
var i = 0;
var table = '<table class="mainTable"><tr><th>item</th><th>image</th><th>description</th></tr>';
$.each(data, function(key, object){
table += ('<tr>');
table += ('<td>' + data.Title + '</td>');
table += ('<td><img src="' + data.ImageURLs.Thumb + '"></td>');
table += ('<td>' + data.Description + '</td>');
table += ('</tr>');
});
table += '</table>';
$('#tableContainer').html(table);
}
});
});

Assuming that your response variable 'data' is an array, you're accessing the wrong variable inside each iteration of your each loop:
$("#button").click(function(){
$.ajax({
type: 'get',
url: "http://www.adweb.agency/interview/api/animals",
data: {format: 'json' },
dataType: 'json',
success: function(data){
var i = 0;
var table = '<table class="mainTable"><tr><th>item</th><th>image</th><th>description</th></tr>';
// NOTE! I changed 'object' to 'value' here
// NOTE 2! We added a JSON.parse on the 'data' variable to convert from JSON to JavaScript objects.
$.each(JSON.parse(data), function(key, value){
// We need to access the value variable in this loop because 'data' is the original array that we were iterating!
table += ('<tr>');
table += ('<td>' + value.Title + '</td>');
table += ('<td><img src="' + value.ImageURLs.Thumb + '"></td>');
table += ('<td>' + value.Description + '</td>');
table += ('</tr>');
});
table += '</table>';
$('#tableContainer').html(table);
}
});
});
See the comments in the above code for the changes.
See the docs on jQuery's .each() iterator here .

here's the right code that you need, just copy and paste, regards!
<!DOCTYPE html>

type: 'get',
success: function (data) {
var i = 0;
var table = '<table class="mainTable"><tr><th>item</th><th>image</th><th>description</th></tr>';
data = $.parseJSON(data)
$.each(data, function (idx, obj) {
table += ('<tr>');
table += ('<td>' + obj.Title + '</td>');
table += ('<td><img src="' + obj.ImageURLs.Thumb + '"></td>');
table += ('<td>' + obj.Description + '</td>');

Try this code:
$.each(data, function(key, object){
table += '<tr>';
table += '<td>' + data[key].Title + '</td>';
table += '<td><img src="' + data[key].ImageURLs.Thumb + '"></td>';
table += '<td>' + data[key].Description + '</td>';
table += '</tr>';
});
