我有一个包含许多锚元素的 Html 页面。这个单一的 Html 页面包含许多 div 部分。一次只显示一个部分，并且会聚焦特定于该部分的锚点。这个 html 还包含一个 div 来打开弹出窗口。当此弹出窗口将打开特定于此的锚点时，将聚焦。现在我想让锚点更早聚焦以弹出锚点聚焦。我的代码如下：-
<body onload="Main.onLoad();" onunload="Main.onUnload();">
<a href='javascript:void(0);' id='anchor' onkeydown='Main.MainKeyHandler();'></a>
<a href='javascript:void(0);' id='anchorAboutUs' onkeydown='Main.MainKeyHandler1();'></a>
<a href='javascript:void(0);' id='anchorSecondScreen' onkeydown='Main.MainKeyHandler2();'></a>
<a href='javascript:void(0);' id='popupanchor' onkeydown='PopupKeyHandler();'></a>
