Question

我在点击其他html文件中的图片后通过javascript加载新的html文件。我这样说window.location.href="page2.html"现在，当尝试使用getElementById()访问page2.html上的元素时，它总是返回null。我认为我的DOM是从第一页创建的，所以它返回null，因为我提供的id不在第一页，而是第二页。如何刷新我的DOM以表示我的新页面？

我的第一个HTML页面

<!DOCTYPE html>
<html>

<link rel="stylesheet" type="text/css" href="mystyle.css">
<head>
    <script src="myScript.js"></script>
</head>

<body class="homepage">
    <header>

        <img id="1" src="crysis.jpg" onClick="showDetails(id)">

        <img id="2" src="bc2.jpg"  onClick="showDetails(bc2)">

</body>

我的第二个HTML页面

<!DOCTYPE html>
<html>

<head>
    <script src="myScript.js"></script>
</head>

<h1 id=headertext></h1>
<img id=boxart height="500" width="500"></img>
</html>

我的脚本文件

function showDetails(imgid){
var imgsrc;
    window.location.href="page2.html"
    alert(imgid);
    switch(imgid)
    {
    case "1":
    alert(document.getElementById("boxart"));
    break;
    case 2:
    imgsrc="BattefieldLarge.jpg"
    break;

    case 3:
    imgsrc="AngryBirdsLarge.jpg"
    break;

    case 4:
    imgsrc="AngryPigsLarge.jpg"
    break;

    }

}

打开一个新的html文件后，getElementById返回null
