任何人都可以指出JSON结构或JS有什么问题,或者我可以调试其中的项目？
编辑(根据Jaromanda X和CH Buckingham回复)：
$('#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));

解决方法
在第155行,你推json,即使它是未定义.
if (pubType=="eForm" || pubType=="PDF") {
var json = createJSONStructure(title,type.toLowerCase(),letax);
}
formItems.push(json);
之后,您尝试获取未定义的item.processid.
您可以在if-block中定义变量,但在这种情况下您应该添加一些验证.
$.each(formItems,item) {
var link;
count = count + 1;
if (item == null) {
return;
}
//add links to parent container
if (item.processid !== "0")
...
});
