问题描述
Ok, so basically what I need is that when I select some text in an <input> or in a <textarea> , a tooltip appears with two buttons, and then get the selected text in a Javascript variable. 
好的，基本上我需要的是，当我在<input>或<textarea>选择一些文本时，工具提示会出现两个按钮，然后在Javascript变量中获取所选文本。
The image below is an example of what I need: 下图是我需要的示例：
var selectedText = "s is an in"
I'm using Powertip for the tooltip and Rangy for manipulating selections in <input> and <textarea> , the problem is that I can't manage to popup the tooltip and get the selected text in a JS variable after I select the text with the cursor. 我使用Powertip工具提示和瘦长的操纵选择<input>和<textarea> ，问题是，我不能设法弹出提示并获得一个JS变量中选定的文本后，我选择与文本光标。
Any suggestions on how to achieve this? 关于如何实现这一目标的任何建议？

This seems to work 这似乎有效
$('input, textarea').powerTip({ manual: true }); // have to prevent default plugin
$('input, textarea').on({
'select': function() {
var selectedText = window.getSelection().toString();
$(this).powertip('show');
},
'blur': function() {
$.powerTip.hide();
}
});

You can add mouse up event on selection of a text and can get the selected text, after that when you will show the selected text, you can also show the tool-tip with that. 您可以在选择文本时添加鼠标向上事件，并可以获取所选文本，此后，当您显示所选文本时，还可以显示带有该提示的工具提示。
Here is the JSFiddle Link for showing the text selection, you can update this and can also show the tool-tip where I have printed the selected text. 这是用于显示文本选择的JSFiddle Link ，您可以对其进行更新，也可以显示我在其中打印所选文本的工具提示。

Use a Modal to create popup, create a Text Field Select Event & a Function to trigger open anchor. 使用模态创建弹出窗口，创建文本字段选择事件，然后使用函数触发打开锚点。 Thats all you need. 那就是您所需要的。
here is a working example I have created: 这是我创建的一个工作示例：
<!doctype html>
<html>
<head>
<meta charset="utf-8">
<title>Text Select Modal</title>
<style>
.modalDialog {
position: fixed;
font-family: Arial, Helvetica, sans-serif;
top: 0;
right: 0;
bottom: 0;
left: 0;
background: rgba(0,0,0,0.8);
z-index: 99999;
opacity:0;
-webkit-transition: opacity 400ms ease-in;
-moz-transition: opacity 400ms ease-in;
transition: opacity 400ms ease-in;
pointer-events: none;
}
.modalDialog:target {
opacity:1;
pointer-events: auto;
}
.modalDialog > div {
width: 300px;
height:130px;
position: relative;
margin: 10% auto;
padding: 5px 20px 13px 20px;
border-radius: 10px;
background: #151414;
}
.close {
background: #606061;
color: #FFFFFF;
line-height: 25px;
position: absolute;
right: -12px;
text-align: center;
top: -10px;
width: 24px;
text-decoration: none;
font-weight: bold;
-webkit-border-radius: 12px;
-moz-border-radius: 12px;
border-radius: 12px;
-moz-box-shadow: 1px 1px 3px #000;
-webkit-box-shadow: 1px 1px 3px #000;
box-shadow: 1px 1px 3px #000;
}
.close:hover { background: #00d9ff; }
</style>
<script type="text/javascript">
function myFunction() {
window.open("#openModal","_self");
}
</script>
</head>
<body>
<input type="text" onSelect="myFunction()">
<div id="openModal" class="modalDialog">
<div>
<a href="#close" title="Close" class="close">X</a>

<input type="button" value="Button 1">
