JS

var calduration = function(){   
    $.each(videoinfo, function(i, obj) {
        alert(obj.startdatetime);
    });
};
var videoinfo = [{"startdatetime":"2014-12-21 00:23:14","totalsecondrun":"2019402310","videolist":
[{"videoid":"uoSDF234","second":"192312"},{"videoid":"0apq3ss","second":"180"}]}];

Answer 1

您需要调用calduration()。

var videoinfo = [{"startdatetime":"2014-12-21 00:23:14","totalsecondrun":"2019402310","videolist": [{"videoid":"uoSDF234","second":"192312"},{"videoid":"0apq3ss","second":"180"}]}];

var calduration = function(){   
    $.each(videoinfo, function(i, obj) {
        alert(obj.startdatetime);
    });
};

calduration();

循环访问videolist数组。您可以添加一个内部循环:

$.each(videoinfo, function(i, obj) {
    $.each(obj.videolist, function(i, obj2) {
        alert(obj2.videoid);
    });
});
