您好，我一直在研究 Javascript 8 滑块拼图（包括事件侦听器在内），并且有代码生成移动数组（用户将点击哪个方块/div id）来解决拼图。

我的目标是让用户能够单击求解按钮，触发一个函数，该函数将播放谜题中的解决方案移动数组。

出于某种原因，我真正难过的地方是，在下面的代码中，点击不适用于循环的每次迭代——这一切都搞砸了。如果有人可以提供任何帮助或建议，我将不胜感激。

while(k < moves.length)
{ 
   var move = "vp" + moves[k];
   var el = document.getElementById(move);
   el.click();  // simulate a users click on div
   populate(); // update array
   k++;
}

编辑 - 对于那些在下面询问的人是事件函数和更多代码......

function addEvent(elem, event, fn) {
// avoid memory overhead of new anonymous functions for every event handler that's installed
// by using local functions
function listenHandler(e) {
    var ret = fn.apply(this, arguments);
    if (ret === false) {
        e.stopPropagation();
        e.preventDefault();
    }
    return(ret);
}

function attachHandler() {
    // set the this pointer same as addEventListener when fn is called
    // and make sure the event is passed to the fn also so that works the same too
    var ret = fn.call(elem, window.event);   
    if (ret === false) {
        window.event.returnValue = false;
        window.event.cancelBubble = true;
    }
    return(ret);
}

if (elem.addEventListener) {
    elem.addEventListener(event, listenHandler, false);
} else {
    elem.attachEvent("on" + event, attachHandler);
}
}

window.onload = function() {
var height = (newImg.height*0.33);
var width = (newImg.width*0.33333);

addEvent(document.getElementById('shuffle'),'click',initGame);
addEvent(document.getElementById('vp1'),'click',move);
addEvent(document.getElementById('vp2'),'click',move);
addEvent(document.getElementById('vp3'),'click',move); // ...

这是 el.click(); 函数的第一部分。打电话...

    function move() {

var e = this;
var id = e.id.charAt(2);

var temp = 0;
//var images = e.getElementsByTagName('img'); 
//alert(images[0].className);
if (id == 1) {
  if (document.getElementById("vp2").innerHTML.indexOf("selected") != -1)
    {    temp = e.innerHTML;
        e.innerHTML = document.getElementById("vp2").innerHTML;    
        document.getElementById("vp2").innerHTML = temp;
        numMoves++;
}else if (document.getElementById("vp4").innerHTML.indexOf("selected") != -1)
    {   temp = e.innerHTML;
        e.innerHTML = document.getElementById("vp4").innerHTML;    
        document.getElementById("vp4").innerHTML = temp;
        numMoves++;
    }
}

jQuery：

$(el).click();

Javascript：

var etype = 'click';
if (el.fireEvent) {
  (el.fireEvent('on' + etype));
}else{
  var evObj = document.createEvent('Events');
  evObj.initEvent(etype, true, false);
  el.dispatchEvent(evObj);
}
