javascript - Ajax/Json - 当列名是数字时如何将返回数据保存在变量中？

Question

当尝试将 json 值存储为来自返回的 ajax 的变量时 ...

$.ajax({
url:'example.php',
type:'POST',
dataType: 'json',
success:function(data){

    var checkname = data.name;  // working
    var check1m = data.1m;      // Here I get the SyntaxError

}
}); 

...它的列名以数字开头(例如 1m):

[{"name":"Peter","city":"London","1m":"not attending","2m":"attending"}]        

我收到以下错误:

SyntaxError: identifier starts immediately after numeric literal

如何将值存储在变量 (check1m) 中？

Answer 1

您可以使用 offset 访问值。就像这样..

 var check1m = data['1m'];    

例子

var json = [{"name":"Peter","city":"London","1m":"not attending","2m":"attending"}] ;
console.log(json[0]['1m']);
