The JSON data obtained from the background today is as follows:var datajson = { ' 0 ': {id:1 } , ' 1 ': {id:2}, ' 2 ': {id:3 }, /c7> ' count ': 1}This JSON we take the data very troublesome, datajson[' 0 '] to get to the first data, and now this JSON does not have the length of this property, so, can not be like the
