I’m replacing some code in an old application, and instead of getting the node

  • 0

I’m replacing some code in an old application, and instead of getting the node by it’s id I get it by it’s class. Because there isn’t a good way to get a node by it’s class in native JS I do it with jQuery, however the new code doesn’t change the img src.

Is there an obvious reason?

Old code:

var gamearea = document.getElementById('gamearea')
var images = gamearea.getElementsByTagName('img');
images[place] = "pics/" + id + ".png";

New code:

$('.gamearea').children('img').eq(place).src = "pics/" + id + ".png";

    .eq() returns a jQuery object. If you want to use the .src property directly, you need a DOM element (not a jQuery object) for which you would use .get() instead of .eq() like this:

    $('.gamearea').find('img').get(place).src = "pics/" + id + ".png";

    I also switched to .find() instead of .children() to be more equivalent to .getElementsByTagName() that you had in the original version and since you didn’t show us your HTML, it seems a safer assumption.
