jquery - Json.parse 返回 null

Question

我不确定为什么下面返回 null 这是我的 json 字符串。是由 JSON 字符串格式引起的吗？

var data = '{"pvd":
            {
            "plannerViewDetailSummary":{"intTargetedCard":6549,"intDeliveredOffer":1,"intRedeemedOffer":1,"dtBegin":"\/Date(1380556800000)\/","dtEnd":"\/Date(1383148800000)\/"},
            "plannerViewDetailChannel":[{"nvarDesc":"Email"}],
            "plannerViewDetailTargetCust":[{"varGroupName":"ALL"}]
            }
    }'

var obj = jQuery.parseJSON(data);
if (obj == null) {
    alert('null');
}

Answer 1

从json中删除换行符或转义，然后尝试，\

var data =  '{"pvd":{"plannerViewDetailSummary":{"intTargetedCard":6549,"intDeliveredOffer":1,"intRedeemedOffer":1,"dtBegin":"\/Date(1380556800000)\/","dtEnd":"\/Date(1383148800000)\/"},"plannerViewDetailChannel":[{"nvarDesc":"Email"}],  "plannerViewDetailTargetCust":[{"varGroupName":"ALL"}]}}';
var obj = jQuery.parseJSON(data);
if (obj==null){
   alert('null');
}
console.log(obj);

问题在于您data至少在javascript中不能以这种方式格式化字符串

var data = '{"pvd":{"plannerViewDetailSummary":{"intTargetedCard":6549,"intDeliveredOffer":1,"intRedeemedOffer":2,"dtBegin":"\/Date(1380556800000)\/","dtEnd":"\/Date(1383148800000)\/"},"plannerViewDetailChannel":[{"nvarDesc":"Email"}],"plannerViewDetailTargetCust":[{"varGroupName":"ALL"}]}}'

var obj = jQuery.parseJSON(data);
if (obj == null) {
    alert('null');
} else {
    alert('ok');
}

字符串中的换行符不是有效的 JSON。删除它们，它会正常工作（或使用 逃避它们\）。
