我有来自服务器的json
数据,我想要提取LimitClass
和LimitClassID
并将其值存储在相应的数组中。
{
"ErrorDesc":"",
"ErrorCode":"",
"LimitClassList":"[{\"LimitClass\":\"L16\\n\",\"LimitClassId\":\"32900\\n\"},{\"LimitClass\":\"28febL0\\n\",\"LimitClassId\":\"31901\\n\"},{\"LimitClass\":\"L14\\n\",\"LimitClassId\":\"31900\\n\"},{\"LimitClass\":\"L17\\n\",\"LimitClassId\":\"32950\\n\"},{\"LimitClass\":\"L15\\n\",\"LimitClassId\":\"31950\\n\"},{\"LimitClass\":\"L0\\n\",\"LimitClassId\":\"21901\\n\"},{\"LimitClass\":\"L4\\n\",\"LimitClassId\":\"23000\\n\"},{\"LimitClass\":\"OTC Send\\n\",\"LimitClassId\":\"30901\\n\"},{\"LimitClass\":\"L2\\n\",\"LimitClassId\":\"22900\\n\"},{\"LimitClass\":\"L12\\n\",\"LimitClassId\":\"28900\\n\"},{\"LimitClass\":\"L6\\n\",\"LimitClassId\":\"23900\\n\"},{\"LimitClass\":\"L1\\n\",\"LimitClassId\":\"25900\\n\"},{\"LimitClass\":\"L13\\n\",\"LimitClassId\":\"29900\\n\"},{\"LimitClass\":\"L7\\n\",\"LimitClassId\":\"24900\\n\"},{\"LimitClass\":\"L8\\n\",\"LimitClassId\":\"26900\\n\"},{\"LimitClass\":\"L10\\n\",\"LimitClassId\":\"27900\\n\"},{\"LimitClass\":\"L13\\n\",\"LimitClassId\":\"30900\\n\"},{\"LimitClass\":\"UatTesting123\\n\",\"LimitClassId\":\"32901\\n\"}]"
}
以下是我尝试的代码:
var list = data.LimitClassList;
var arrayLimitClass = [];
var arrayLimitClassId = [];
for(var i in list) {
arrayLimitClass.push(list[i].LimitClass);
arrayLimitClassId.push( list[i].LimitClassId);
}
alert(list);
alert(arrayLimitClass);
alert(arrayLimitClassId);
当我发出警告时,列表变量有以下结果:
[{\"LimitClass\":\"L16\\n\",\"LimitClassId\":\"32900\\n\"},{\"LimitClass\":\"28febL0\\n\",\"LimitClassId\":\"31901\\n\"},{\"LimitClass\":\"L14\\n\",\"LimitClassId\":\"31900\\n\"},{\"LimitClass\":\"L17\\n\",\"LimitClassId\":\"32950\\n\"},{\"LimitClass\":\"L15\\n\",\"LimitClassId\":\"31950\\n\"},{\"LimitClass\":\"L0\\n\",\"LimitClassId\":\"21901\\n\"},{\"LimitClass\":\"L4\\n\",\"LimitClassId\":\"23000\\n\"},{\"LimitClass\":\"OTC Send\\n\",\"LimitClassId\":\"30901\\n\"},{\"LimitClass\":\"L2\\n\",\"LimitClassId\":\"22900\\n\"},{\"LimitClass\":\"L12\\n\",\"LimitClassId\":\"28900\\n\"},{\"LimitClass\":\"L6\\n\",\"LimitClassId\":\"23900\\n\"},{\"LimitClass\":\"L1\\n\",\"LimitClassId\":\"25900\\n\"},{\"LimitClass\":\"L13\\n\",\"LimitClassId\":\"29900\\n\"},{\"LimitClass\":\"L7\\n\",\"LimitClassId\":\"24900\\n\"},{\"LimitClass\":\"L8\\n\",\"LimitClassId\":\"26900\\n\"},{\"LimitClass\":\"L10\\n\",\"LimitClassId\":\"27900\\n\"},{\"LimitClass\":\"L13\\n\",\"LimitClassId\":\"30900\\n\"},{\"LimitClass\":\"UatTesting123\\n\",\"LimitClassId\":\"32901\\n\"}]
但是当我提醒arrayLimitClass
和arrayLimitClassId
时,我会得到点(。)。在提取json
对象的行?
答案 0 :(得分:2)
"LimitClassList":"[{\"LimitClass\":\"L1....]"
^ ^
LimitClassList是一个字符串,而不是一个数组。使它成为一个实际的数组,而不是你的代码应该工作。应该没有理由再次解析它。
答案 1 :(得分:2)
data.LimitClassList
以下的值本身就是一个包含JSON的String。你必须先解码它。
var list = JSON.parse( data.LimitClassList );
var arrayLimitClass = [];
var arrayLimitClassId = [];
// ...
这或多或少是一种解决方法。您应该查看服务器代码并修复编码错误!
