Add item to JSON object

Question

I have a JSON object that i'm try to add to. Below is the code i'm using (the commented out bit also didn't seem to do what I need) :

$('#classes tbody').on('click', 'tr', function () {
 $(this).toggleClass('selected'); 
 if ($.isEmptyObject(jsonData)) { 
 jsonData = {
 "row": [
 {
 "OpenClosed": $('tr.selected td:nth-child(1)').text(),
 "Section": $('tr.selected td:nth-child(2)').text(),
 "CRN": $('tr.selected td:nth-child(3)').text(),
 "CreditHours": $('tr.selected td:nth-child(4)').text()
 }
 ]
 };
 }
 else if (!$.isEmptyObject(jsonData)) { 
 jsonData['row'] = {
 "OpenClosed": $('tr.selected td:nth-child(1)').text(),
 "Section": $('tr.selected td:nth-child(2)').text(),
 "CRN": $('tr.selected td:nth-child(3)').text(),
 "CreditHours": $('tr.selected td:nth-child(4)').text()
 }; 
 //jsonData.row.push = {
 // "OpenClosed": $('tr.selected td:nth-child(1)').text(),
 // "Section": $('tr.selected td:nth-child(2)').text(),
 // "CRN": $('tr.selected td:nth-child(3)').text(),
 // "CreditHours": $('tr.selected td:nth-child(4)').text()
 //}; 
 } 
});

The user clicks on a row and I need it to add that row where class=selected to the JSON object. Currently it appears to append (in Chrome Dev Tools) instead of add a new row. When I selected two rows I end up with this CRN: "8063780639" where the CRNs should be 80637 and 80639 on separate rows. I need each click to add a row like row[0], row[1], row[2] etc...

push is not a property, it is a method. So you have to call it using (...)

jsonData.row.push({
 "OpenClosed": $('tr.selected td:nth-child(1)').text(),
 "Section": $('tr.selected td:nth-child(2)').text(),
 "CRN": $('tr.selected td:nth-child(3)').text(),
 "CreditHours": $('tr.selected td:nth-child(4)').text()
 }); 

• BobbyDazzler: Damn, got it before me :D Exactly the same as what I was going to write.
• Jrow: This is what I get when I use push correctly http://imgur.com/ITAmazn
• devnull69: The result shows me that you still used jsonData.row.push = ... instead of jsonData.row.push(...)
