I am getting an error when trying to parse JSON:
SyntaxError: Unexpected token u in JSON at position 0(…) eFormsAtoZIndex.aspx:6558 Full Code: http://pastebin.com/LXpJN8GF
Relevant Code:

EDIT (As per Jaromanda X's and CH Buckingham reply):
$('#hdnAggregateAll').val(JSON.stringify(aggregateAll)); console.log(aggregateAll); $('#hdnAggregatePersonal').val(JSON.stringify(aggregatePersonal)); $('#hdnAggregateBusiness').val(JSON.stringify(aggregateBusiness)); $('#hdnMinistryAggregate').val(JSON.stringify(ministryAggregate)); $('#hdnCAAggregate').val(JSON.stringify(caAggregate)); $('#hdnSTaxAggregate').val(JSON.stringify(sTaxAggregate)); $('#hdnBTaxAggregate').val(JSON.stringify(bTaxAggregate)); $('#hdnLETaxAggregate').val(JSON.stringify(leTaxAggregate)); ERROR:

On the line 155 you push json even if it's undefined.
if (pubType=="eForm" || pubType=="PDF") { var json = createJSONStructure(title, desc, index, type.toLowerCase(), formLink, documentLink, pubType, processId, ministry, ca, stax, btax, letax); } formItems.push(json); And after it your are trying to get item.processid of undefined. You can define variables in if-block, but in the case you should to add some validation.
$.each(formItems, function(i, item) { var link; count = count + 1; if (item == null) { return; } //add links to parent container if (item.processid !== "0") ... });
