我如何阅读toppings数组值？

我试着用这种方式阅读

for (var n = 0; n < toppins.values.length; n++) 
{
alert(toppins.values[n]);
}

但是它给errror无法读取未定义的属性

任何人都可以帮我解决这个问题。

Answer 1

Demo Fiddle

Javascript代码：

for (var i = 0; i < json.length; i++) {
    var obj = json[i].toppings;
    for (var j = 0; j < obj.length; j++) {
        alert(obj[j].value);
    }
}

Answer 2

根据你的JSON，你有一个错字，value不是values而toppings不是toppins：

for (var n = 0; n < toppings.value.length; n++) 
{
alert(toppings.value[n]);
}
