I am new to Json and Javascript .

What i am trying to do is , when i click the plus sign (inside the datatable) , it should display the order details into a dynamically generated html table , with headers , rows and cells , for every Order ID. I am trying to store the JSON data from url into an array and than loop through it , and than display them corresponding every Order ID into a html table . So this is my View and controller method :

<style>

    td.details-control {
    background: url('/Content/images/details_open.png') no-repeat center center;
    width:40px;
    height:5px;
    cursor: pointer;
}
tr.details td.details-control {
    background: url('/Content/images/details_close.png') no-repeat center center;
    width:40px;
    height:5px;
}


</style>


    <table id="example" class="display" cellspacing="0" width="100%">
        <thead>
            <tr>
                <th></th>
                <th>Order  ID</th>

                <th>Customer ID</th>
                <th>ContactName</th>
                <th>Employee ID</th>
                <th>Order Date</th>
                <th>Required Date</th>
                <th>Ship Via</th>
                <th>Freight</th>

                <th>Ship Address</th>
                <th>Ship City</th>
                <th>Ship Region</th>
                <th>Ship Postal</th>
                <th>Ship Country</th>
            </tr>
        </thead>
   
        <tfoot>
            <tr>
                <th></th>
                <th>Order  ID</th>

                <th>Customer ID</th>
                <th>ContactName</th>

                <th>Employee ID</th>
                <th>Order Date</th>
                <th>Required Date</th>
                <th>Ship Via</th>
                <th>Freight</th>
                <th>Ship name</th>
                <th>Ship Address</th>
                <th>Ship City</th>
                <th>Ship Region</th>
                <th>Ship Postal</th>
                <th>Ship Country</th>
            </tr>

JavaScript

var jqxhr = $.getJSON( "url", function(jsonResult) {
  ParseJson(jsonResult);
})

function ParseJson(response)
{
 var html = "";
  for(var i=0; i<response.length; i++){
    html += "<tr>"
    html += "<td>" + response[i].ContactName + "</td>";
    ///other td
    html += "</tr>"
  }
$(document).find("#dynamicId").html(html);
}

ParseJson(jsonResult);
})

function ParseJson(response) {
var html = "";
for (var i = 0; i < response.length; i++)
{
for (var j = 0; i <= response[i].OrderID; j++)
{
html += ""
html += "" + response[j].ProductID + "";
html += "" + response[j].ProductName + "";
html += "" + response[j].UnitPrice + "";
html += "" + response[j].Quantity + "";
html += "" + response[j].Discount + "";
///other td
html += ""
}
}
$(document).find("#entrydata").html(html);
}
