这个问题已经过大量编辑，
我需要使用一个重置按钮来重置此代码，以便可以从currentItem 1中再次使用它，问题是仅重置当前项目，并且突出显示的列表项仍被设置为好像当前项不在1一样。

 var stuff = new Array();
stuff["li_1"]="ext_1";
stuff["li_2"]="hc_1";
stuff["li_3"]="ext_2";
stuff["li_4"]="ext_3";
stuff["li_5"]="hc_2";
stuff["li_6"]="ext_4";
stuff["li_7"]="hc_3";
stuff["li_8"]="ext_5";
stuff["li_9"]="hc_4";
stuff["li_10"]="ext_6";
stuff["li_11"]="hc_5";
var currentItem=1;
var extWrong=false;
var extCorrect=false;
var hcWrong=false;
var hcCorrect=false;

$(document).ready(function(e) {
    //document.ontouchmove = function(e){ e.preventDefault(); }
    $('#li_1').draggable({revert:true} );
    $("#li_1").addClass("highlighted");
    $('.drop_area').droppable({
         tolerance:"pointer",
         drop:function (event, ui) {
            var tmpID=$(ui.draggable).attr("id");
            var droppableID = $(this).attr("id");
            var audioToPlay="";
            $("#" + tmpID).hide();
            $("#" + stuff[tmpID]).show();
            $("#" + stuff[tmpID]).addClass("highlighted");

            currentItem++;

            var dragType=tmpID.split("_")[1];
            dragType=(dragType=="1" || dragType=="3" ||dragType=="4" ||dragType=="6" ||dragType=="8" ||dragType=="10")?"ext":"hc";
            var dropType=droppableID=="extreme_thoughts"?"ext":"hc";

            if(dragType=="ext" && dropType=="ext"){
                    audioToPlay=extCorrect==false?"IntDragDrop_ExtremeCorrect.mp3":"ding.mp3";
                    extCorrect=true;
            }else if(dragType=="ext" && dropType=="hc"){
                    audioToPlay=extWrong==false?"IntDragDrop_ExtremeIncorrect.mp3":"pop4c.mp3";
                    extWrong=true;
            }else if(dragType=="hc" && dropType=="hc"){
                    audioToPlay=hcCorrect==false?"IntDragDrop_HealthyCorrect.mp3":"ding.mp3";
                    hcCorrect=true;
            }else if(dragType=="hc" && dropType=="ext"){
                audioToPlay=hcWrong==false?"IntDragDrop_HealthyIncorrect.mp3":"pop4c.mp3";
                    hcWrong=true;

            }
            playSound(audioToPlay,"#" + stuff[tmpID],"#" + "li_" + currentItem);

            }

    });

这是我坏了的按钮。

$("#restart").click(function(){
  currentItem=1;
    var extWrong=false;
    var extCorrect=false;
    var hcWrong=false;
    var hcCorrect=false;
  $("#ext_1,#ext_2,#ext_3,#ext_4,#ext_5,#ext_6,#hc_1,#hc_2,#hc_3,#hc_4,#hc_5,#congrats").hide()
  $("#li_1,#li_2,#li_3,#li_4,#li_5,#li_6,#li_7,#li_8,#li_9,#li_10,#li_11,#hide_me,#hide_me2").show()
  $("#li_2,#li_3,#li_4,#li_5,#li_6,#li_7,#li_8,#li_9,#li_10,#li_11").removeClass("highlighted");
    alert(currentItem)
});

最佳答案

您的作业中有错别字，您正在执行currentItem==1而不是currentItem=1;
