$(document).ready(function() {
  var getText = function(opt) {};

  var temp = $("#hidDays").val();

  //Add More Groups
  $("#main-wrapper").on("click", ".addGroupBtn", function() {
    console.log("fsdfa");
    var template = $("#timeGroupTemplate");
    var btnTemplate = $("<div/>").append($("#btnTemplate").html());
    var div = $("<div/>").append(template.html());
    btnTemplate.find(".addGroupBtn").remove();

    $("#periodDiv")
      .find(".timePeriodDiv")
      .find(".addRemBtn")
      .html(btnTemplate.html());
    $("#periodDiv")
      .find(".timePeriodDiv")
      .last()
      .after(div.html());
  });

  //Remove More Groups
  $("#main-wrapper").on("click", ".removeGroupBtn", function() {
    var btnTemplate = $("<div/>").append($("#btnTemplate").html());
    $(this)
      .parents(".timePeriodDiv")
      .remove();
    var template = $(".timePeriodDiv").length;
    if (template === 2) {
      btnTemplate.find(".removeGroupBtn").remove();
    }
  });
});
