`[window](https://geek.csdn.net/educolumn/03e5a5a554174a38fdfeb8376bd685e2?spm=1055.2569.3001.10083).focus()` 方法可以将当前[窗口](https://geek.csdn.net/educolumn/00d3d1b467be187bf63895f811603770?spm=1055.2569.3001.10083)设置为焦点[窗口](https://geek.csdn.net/educolumn/00d3d1b467be187bf63895f811603770?spm=1055.2569.3001.10083)。它只有在用户与浏览器交互时才能工作。
使用方法很简单,只需要在 JavaScript 中调用 `window.focus()` 方法即可。例如:
```javascript
<button onclick="myFunction()">Focus window</button>
<script>
function myFunction() {
window.focus();
</script>
当用户单击按钮时,[窗口](https://geek.csdn.net/educolumn/00d3d1b467be187bf63895f811603770?spm=1055.2569.3001.10083)将获得焦点。请注意,某些浏览器可能会阻止[窗口](https://geek.csdn.net/educolumn/00d3d1b467be187bf63895f811603770?spm=1055.2569.3001.10083)获取焦点,因此可能不会在所有情况下起作用。

window.open弹窗置顶
根据你提供的引用内容,你想要实现使用window.open()方法打开一个新页面,并且让这个弹窗置顶显示。而,根据你的描述,这种方法在IE浏览器中不起作用。你还尝试了在本地测试中使用window.onclick = function (){childWindow.focus();}来解决这个问题,但在虚拟桌面中仍然无效。可能是由于浏览器版本或其他原因导致的。以下是一种可能的解决方案[^1]:
```javascript
var childWindow = window.open("your_url", "_blank", "top=0,left=0,width=500,height=500");
childWindow.focus();
这段代码将打开一个新的窗口,并将其置于屏幕的左上角。然后,使用childWindow.focus()方法将焦点设置到新窗口,使其置顶显示。请注意
