Answer 1

var x =localStorage.getItem("offlinecurries1");

此行返回一个字符串！

您需要将字符串解析为json对象，在

之后添加此行

var x =localStorage.getItem("offlinecurries1");
x = JSON.parse(x)

Answer 2

试试这个。保存时需要strigify，在检索时需要使用parse JSON.parse json，以便将其转换回数组。

var json = { "totalSize": 497, "done": true, "records": [{ "attributes": { "type": "PricebookEntry", "url": "/services/data/v36.0/sobjects/PricebookEntry/01u36000001de83AAA" }, "Id": "01u36000001de83AAA", "Name": "P-0025", "Pricebook2Id": "01s36000004AGVLAA4", "Product2": { "attributes": { "type": "Product2", "url": "/services/data/v36.0/sobjects/Product2/01t36000001To1lAAC" }, "Product_Image_URL__c": null, "Description": "ACHAPPAM175GMS X12PKT", "Family": null, "Product_Image__c": "" }, "Product2Id": "01t36000001To1lAAC", "Pricebook2": { "attributes": { "type": "Pricebook2", "url": "/services/data/v36.0/sobjects/Pricebook2/01s36000004AGVLAA4" }, "Name": "UK Pricebook" } }, { "attributes": { "type": "PricebookEntry", "url": "/services/data/v36.0/sobjects/PricebookEntry/01u36000001de84AAA" }, "Id": "01u36000001de84AAA", "Name": "P-0026", "Pricebook2Id": "01s36000004AGVLAA4", "Product2": { "attributes": { "type": "Product2", "url": "/services/data/v36.0/sobjects/Product2/01t36000001To1mAAC" }, "Product_Image_URL__c": null, "Description": "ADA RICE 200 x 30", "Family": null, "Product_Image__c": "" }, "Product2Id": "01t36000001To1mAAC", "Pricebook2": { "attributes": { "type": "Pricebook2", "url": "/services/data/v36.0/sobjects/Pricebook2/01s36000004AGVLAA4" }, "Name": "UK Pricebook" } }] };
var y = json.records;
alert(y);
localStorage.setItem("offlinecurries1", JSON.stringify(y));
var x = JSON.parse(localStorage.getItem("offlinecurries1"));
alert(x[0].Name);
