我在解析JSON时出错:

}
}
}
Can anyone point out what is wrong with the JSON structure or JS or how I can debug items within it?
有人能指出JSON结构或JS有什么问题吗?或者我如何在其中调试项目?
EDIT (As per Jaromanda X's and CH Buckingham reply):

$('#hdnAggregateAll').val(JSON.stringify(aggregateAll));

On the line 155 you push json even if it's undefined.
在第155行，即使json没有定义，也要按它。
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.
在它之后，你试图获得物品。processid的定义。您可以在if-block中定义变量，但是在这种情况下，您应该添加一些验证。
$.each(formItems, function(i, item) {
var link;
count = count + 1;
if (item == null) {
return;
}
//add links to parent container
if (item.processid !== "0")
...
});
