So i am dynamically adding buttons to a table based on array values returned from my generateFolderTree function, problem is i can't seem to get the text value of a clicked button or even get any events when i click the created buttons. How can i get the name of a clicked button? Code below....Thanks

Answer 1

 $('document').on('click', '.selectedFolder', function () {

            alert($(this).text())
        });

Answer 2

Put this piece of code of yours in $(document).ready

$(".selectedFolder").click(function () {
var text = $(this).text();
console.log(text);
$("#dialog-status").val(text);
}); 

Answer 3

use

$(ELEMENT/CLASS/ID).on('click', function(){});

instead of

$(ELEMENT/CLASS/ID).click

click() function doesnt consider elements added to DOM dynamically before we used to use live() for attaching events for dynamically created element but since live() is depreciated we should use on()

on() acts as live()
