【中文标题】如何将弹出框放置在突出显示的文本部分上？【英文标题】：How to position popover over a highlighted portion of text? 【发布时间】：2015-03-30 13:21:10 【问题描述】：假设存在正文的这种情况。而且，在突出显示其中的一个单词时，我希望显示一个弹出框，其中工具提示位于突出显示的单词处。
有点像 mac 如何显示以下单词的定义 -
这是一个 angularjs 应用程序，正在使用 angularui。因此，以角度 ui 为重点的解决方案将是可取的，但不是必需的。
提前致谢。
【问题讨论】：
ui.bootstrap.popover 可能会有所帮助。 @showdev 已经使用它并让弹出框通过自定义触发器和所有内容处理元素。但是，将工具提示定位在突出显示的文本部分上似乎是不可能的（我想相信可能但不是微不足道的）。 我明白了。您介意将您尝试的代码添加到您的问题中，以便我们可以重现该问题吗？它可能有助于我们可视化您的问题并找到解决方案。 【参考方案1】：你可以使用下面的代码来做你想做的事……祝你好运：
<html>
<head>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.2/jquery.min.js"></script>
<script>
function getSelectedText()
var text = "";
if (typeof window.getSelection != "undefined")
text = window.getSelection().toString();
else if (typeof document.selection != "undefined" && document.selection.type == "Text")
text = document.selection.createRange().text;
return text;
function doSomethingWithSelectedText()
var selectedText = getSelectedText();
if (selectedText)
$('#infoDiv').css('display', 'block');
$('#infoDiv').css('position', 'absolute');
$('#infoDiv').css('left', event.clientX + 10);
$('#infoDiv').css('top', event.clientY + 15);
else
$('#infoDiv').css('display', 'none');
;
;
document.onmouseup = doSomethingWithSelectedText;
document.onkeyup = doSomethingWithSelectedText;
</script>

/*Tooltip div styling */
