javascript - jQuery remove highlight only if already selected -


this should basic fix. im wanting remove selected class when clicking on highlighted button. 1 button highlighted @ given time.

http://jsfiddle.net/7wy7sjm5/1/

the reason have remove class of them execute first because when 1 clicked, 1 highlighted, , not have previous clicked ones still highlighted. , when clicking on same button highlighted, remove highlight. hope makes sense.

$(".details-btn").on("click", function(){ var $this = $(this); //add/remove selected button $(".details-btn").removeclass("selected"); $this.toggleclass("selected");});

possibly using .each() cycle through each instance of button , if has class remove? ive tried different approaches , none working way want.

in case can make use of .not().

basically, remove .selected .details-btn except current 1 not(this). then, use toggle()

$(".details-btn").on("click", function() {   var $this = $(this);   $(".details-btn").not(this).removeclass("selected");   $this.toggleclass("selected"); }); 

$(".details-btn").on("click", function() {    var $this = $(this);    $(".details-btn").not(this).removeclass("selected");    $this.toggleclass("selected");  });
