jQuery Question

Displaying JSON data in HTML

I am developing a Hybrid App using intel XDK. On the app I am using ajax request to my PHP server. The server will respond with json data.

This is my sample json from the server.

[{
"id":"11",
"user_id":"8000",
"product":"Shoes A",
"quantity":"1",
"date_open":"2015-01-04",
"paid":"1",
"harvested":"",
"reinvest":null,
"profit":null,
"investment":"3000"
},

{
"id":"12",
"user_id":"8000",
"product":"Shoes B",
"quantity":"1",
"date_open":"2015-03-01",
"paid":"1",
"harvested":"",
"reinvest":null,
"profit":null,
"investment":"1500"
}]


The number of product per user here is different, some have no product, some have 1, 2...10 etc. products. So depending on how many the product of a user, what is the best way displaying them. So that the data/items are all organize and well displayed with image upon page loaded.

Should be displayed automatically:

| image of product | name of product | date | profit | investment

What should my html page/css style setup? Or anything I should know more about this.

On my existing system using PHP. I just use a foreach of user product. Then a style every class where the data will be displaying.
Sample:

foreach(products as product){
?>
<div class="img"></div>
<div class="productname">echo product['product'];</div>
<?
}


So i'm thinking if it possible to display it in html like what I did in PHP. Thanks for help.

Edit: My ajax call in client side:

$("button").click(function(){
$.ajax({
type: 'POST',
url: "http://www.sample.com/app/user-data.php",
crossDomain: true,
dataType: 'json',
data: { user_token: user_token },
success: function(data, status, jqXHR) {
//console.log(data); //`this is displaying only as object why?`
//console.log(status);
console.log(JSON.stringify(data)); //to string
},

error: function(xhr, ajaxOptions, thrownError) {
alert(ajaxOptions + " " + thrownError);
}
});
});

Answer

Server should supply json like:

<?php
$data = array();
foreach(products as product){
    array_push($data, $product);
}
header('Content-Type: application/json');
echo json_encode($data);

You should fetch the data by ajax and then update the DOM:

var dummy_data = [{
    "id": "11",
    "user_id": "8000",
    "product": "Shoes A",
    "quantity": "1",
    "date_open": "2015-01-04",
    "paid": "1",
    "harvested": "",
    "reinvest": null,
    "profit": null,
    "investment": "3000"
  },

  {
    "id": "12",
    "user_id": "8000",
    "product": "Shoes B",
    "quantity": "1",
    "date_open": "2015-03-01",
    "paid": "1",
    "harvested": "",
    "reinvest": null,
    "profit": null,
    "investment": "1500"
  }
];

function addData(data) {
  data.forEach(function(row) {
    var str = '<tr>';
    str += '<td>' + row.id + '</td>';
    str += '<td>' + row.product + '</td>';
    str += '<td>' + row.date_open + '</td>';
    str += '<td>' + row.profit + '</td>';
    str += '<td>' + row.investment + '</td>';
    str += '</tr>';
    $('#data_tbl').append(str);
  });
}
$("#fetch_btn").click(function() {
  //do ajax here and load data
  /*
  $.getJSON("get_data.php", function(result) {
    addData(result);
  });
  */
  //for demo calling the function with dummy data
  addData(dummy_data);
});
table,
th,
td {
  border: 1px solid black;
}
