I want to use each() on a JSON array but my alert function isn't running.
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"}]}];
You need to call 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();
Like this.
To loop through the videolist array. You could add an inner loop:
$.each(videoinfo, function(i, obj) {
$.each(obj.videolist, function(i, obj2) {
alert(obj2.videoid);
});
});
Like this.
videolist item ? like videoid and second
videoinfo after you've declared calduration() but you must do it before calling calduration(). Personally it makes more sense to me to define it before the function it is used in.videolist ?Add videoinfo above from each function, and calduration is function so you will need to self call using () or call function, see below sample code
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);
});
}();
OR
calduration();
OR
calduration.call();
UPDATE
$.each(videoinfo[0].videolist, function(i, obj) {
alert(obj.startdatetime);
});
Or if videoinfo have multiple objects then you can iterate two times using each() function
var videoinfo = [{
"startdatetime": "2014-12-21 00:23:14",
"totalsecondrun": "2019402310",
"videolist": [{
"videoid": "uoSDF234",
"second": "192312"
}, {
"videoid": "0apq3ss",
"second": "180"
}]
}];
$.each(videoinfo, function(i, obj) {
$.each(obj.videolist, function(j, o) {
alert(o.videoid);
});
});<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>videolist json ?
videoinfo[0].videolist key in each() or if above object multiple then two iterate by each() function.. see updated answervideolist another object that is inside parent videoinfo[1], [2]....n object.videoid is uoSDF234 and get it secondTry this:
var videoinfo = [{"startdatetime":"2014-12-21 00:23:14","totalsecondrun":"2019402310","videolist":
[{"videoid":"uoSDF234","second":"192312"},{"videoid":"0apq3ss","second":"180"}]}];
$(document).ready(function() {
$.each(videoinfo, function(i, obj) {
alert(obj.startdatetime);
});
});
