javascript - 无法将 JSON 字符串转换为 javascript 对象

Question

    var JSONObj='[{"rmaNumber":null,"orderReferenceNumber":"referene45","orderStatus":"Pending","dateRequested":null,"dateApproved":null,"segateAddress":null,"billingAddress":null,"shippingAddress":null,"returnForCredit":{"requested":null,"received":null,"shipped":35,"credited":45,"invoiceAmount":null},"returnForExchange":{"requested":null,"received":null,"shipped":35,"credited":45,"invoiceAmount":null},"totals":null}]'
    var parsedJSON = eval('(\'+JSONObj+\')');    
    var result=parsedJSON.result;
    var count=parsedJSON.count;
    alert('result:'+result+' count:'+count);

提醒它给出 undefined :undefined

Answer 1

你应该使用 JSON.parse()为此:

var parsedJSON = JSON.parse(JSONObj);
console.log(parsedJSON[0].orderStatus);  // "Pending"

注意:只有现代浏览器支持此方法。了解浏览器兼容性 here .
