如何隔离first_name
键以在以下对象中输出其值?
{
"first_name": "D",
"last_name": "N",
"phone_number": 1233414234
}
最佳答案
您可以使用.
或[]
var x = {"first_name":"D","last_name":"N","phone_number": 1233414234};
alert(x.first_name);
alert(x['first_name']);

根据另一个答案的注释中的OP问题:如果要遍历数组的对象,则可以使用每个对象。
var array = [{"first_name":"D","last_name":"N","phone_number": 1233414234},{"first_name":"P","last_name":"T","phone_number": 1233414234}];
$.each(array, function(idx) {
alert(array[idx].first_name);
});
要么
var array = [{"first_name":"D","last_name":"N","phone_number": 1233414234},{"first_name":"P","last_name":"T","phone_number": 1233414234}];
$.each(array, function(idx, obj) {
alert(obj.first_name);
});
