jquery - Progress Bar Increment/Decrement -


i need progress bar semantic ui. i'm trying replicate first example increment/decrement button, life of me, can't work, on matter or sample javascript code appreciated.

the code page located here, , looking @ section in particular:

$buttons   .on('click', function() {     var       $progress = $(this).closest('.example').find('.ui.progress')     ;     if( $(this).hasclass('increment') ) {       $progress.progress('increment');     }     else {       $progress.progress('decrement');     }   }) ;

as can see, each button added click event. then, $progress assigned closest found progress bar. finally, check class of button (to know if in/decrement) , .progress value gets used accordingly.

while @ it, here's html use buttons:

<div class="example">   <div class="ui progress">     <div class="bar">       <div class="progress"></div>     </div>   </div>   <div class="ui icon buttons">     <div class="decrement ui basic red button"><i class="minus icon"></i></div>     <div class="increment ui basic green button"><i class="plus icon"></i></div>   </div> </div>
