javascript - Get image attribute based on class name -

-

i have images have data-url attribute want value of data-url based on click on element.

my html is

<img class="youtube-poster" src=" http://i2.ytimg.com/vi/juijgbxj-4w/maxresdefault.jpg " data-url="https://www.youtube.com/embed/juijgbxj-4w"> <div class="video-poster-player"><i class="play"></i><div>

and js is

$(document).on('click', '.video-poster-player', function(event) {   var classname = $(event.target).attr('class');   var frameurl = classname.parent().find('.youtube-poster').data('url')    console.log(classname)   console.log(frameurl) });

in console classname.parent not function

so, .parent() valid on jquery object , not on string (classname). following work scenario (not pretty, works).

<img class="youtube-poster" src=" http://i2.ytimg.com/vi/juijgbxj-4w/maxresdefault.jpg " data-url="https://www.youtube.com/embed/juijgbxj-4w"> <div class="video-poster-player">     <i class="play">play</i> <div>

js:

$(document).on('click', '.video-poster-player', function(event) {     alert ($(this).prev('.youtube-poster').data('url')); });

a cleaner solution group image , play icons, use closest , find want, this example.
