Question

我正在尝试获取数组中对象的值，即数组中对象的值。

的jQuery

// aim:  to alert value of 'm1' for each object (represented as a day)

myArray = [{"monday":[{"m1":"val1"},{"s1":"val2"},{"m2":"val3"},{"s2":"val4"},{"m3":"val5"},{"s3":"val6"}]},{"tuesday":[{"m1":"val1"},{"s1":"val2"},{"m2":"val3"},{"s2":"val4"},{"m3":"val5"},{"s3":"val6"}]},{"wednesday":[{"m1":"val1"},{"s1":"val2"},{"m2":"val3"},{"s2":"val4"},{"m3":"val5"},{"s3":"val6"}]},{"thursday":[{"m1":"val1"},{"s1":"val2"},{"m2":"val3"},{"s2":"val4"},{"m3":"val5"},{"s3":"val6"}]},{"friday":[{"m1":"val1"},{"s1":"val2"},{"m2":"val3"},{"s2":"val4"},{"m3":"val5"},{"s3":"val6"}]},{"saturday":[{"m1":"val1"},{"s1":"val2"},{"m2":"val3"},{"s2":"val4"},{"m3":"val5"},{"s3":"val6"}]},{"sunday":[{"m1":"val1"},{"s1":"val2"},{"m2":"val3"},{"s2":"val4"},{"m3":"val5"},{"s3":"val6"}]}]

$.each(myArray, function(k,v) {
  $.each(k, function(k2,v2) {
      alert(v2.m1)
});
});

试试这个：http://jsfiddle.net/merrifield69/py8Jz/5/

$.each(myArray, function (k, v) {
    $.each(v, function (k2, v2) {
        alert(v2[0].m1)
    });
});

如果您只需要花一点时间考虑每个循环中的位置，那么很容易理解。：

如何使用jQuery $ .each访问数组内对象内的对象内的值？
