Почему я получаю неопределенное значение при попытке получить динамически добавляемый атрибут данных?
I'm trying to get the value for data-tab-id based on the class .tab-btn.active | however, the result keeps returning undefined.
This is where I add the data attribute
$navigation.find(".tab-btn").each(function(i, ele) { $(ele).attr("data-tab-id", i); }); This is where I retrieve it
var autoSwitch = setInterval(function() { //Get maximum # of tabs maxTabs = $(".tab-btn").length; //Get the currently active button pastActiveBtn = $(".tab-btn").find(".active"); pastId = pastActiveBtn.data('tabId'); //I have also tried tab-id; also 'undefined' console.log(pastId); //OUTPUT = undefined }); If anyone knows why I am getting this, I'd appreciate it.
