txt = corp.createTextRange()
txt.execCommand("Copy")

问题
The aforementioned code isn't working and is resulting in an object expected error. Any help is appreciated!
I have seen a library out there called zeroclipboard, but would prefer to write my own function.
上述代码不起作用，并导致object expected error. 任何帮助表示赞赏！我见过一个名为 的库zeroclipboard，但更愿意编写自己的函数。
Edit:

I now have this function to select text on the page. is it possible to write a formula to copy the selected range as is?
我现在有这个功能来选择页面上的文本。是否可以编写一个公式来按原样复制所选范围？
function containerSelect(id) {
containerUnselect();
if (document.selection) {
var range = document.body.createTextRange();
range.moveToElementText(id);
range.select();
} else if (window.getSelection) {
var range = document.createRange();
range.selectNode(id);
window.getSelection().addRange(range);
}
}<label onclick="containerSelect(this); select_all()">
<p>hello world</p>

With modern browsers, if you want copy rich textonly, there is a very easy solution without using any packages. See http://jsfiddle.net/jdhenckel/km7prgv4/3
对于现代浏览器，如果您只想复制富文本，有一个非常简单的解决方案，无需使用任何包。见http://jsfiddle.net/jdhenckel/km7prgv4/3
Here is the source code from the fiddle
这是小提琴的源代码
<button onclick="copyToClip(document.getElementById('foo').innerHTML)">
Copy the stuff
</button>
<div id=foo style="display:none">
This is some data that is not visible.
You can write some JS to generate this data.
It can contain rich stuff. <b> test </b> me <i> also </i>
<span style="font: 12px consolas; color: green;">Hello world</span>
You can use setData to put TWO COPIES into the same clipboard,
one that is plain and one that is rich.
That way your users can paste into either a
<ul>
<li>plain text editor</li>
<li>or into a rich text editor</li>
</ul>
</div>
the function
功能
function copyToClip(str) {
function listener(e) {
e.clipboardData.setData("text/html", str);
e.clipboardData.setData("text/plain", str);
e.preventDefault();
}
document.addEventListener("copy", listener);
document.execCommand("copy");
document.removeEventListener("copy", listener);
};

This tiny JS plugin copies richtext without using Flash: https://www.npmjs.com/package/clipboard-js
这个小小的 JS 插件无需使用 Flash 即可复制富文本：https: //www.npmjs.com/package/clipboard-js
It's based on https://clipboardjs.com/- but it's an upgrade in my opinion, because the original only supports plain text.
它基于https://clipboardjs.com/- 但在我看来它是一个升级，因为原来只支持纯文本。
The code is simple:
代码很简单：
clipboard.copy({
"text/html": "<i>Markup</i> <b>text</b>. Paste me into a rich text editor."
});

Well here is the deal most modern web browsers wont let you have access to the clip board. However like with everything there is a work around.
好吧，这是大多数现代网络浏览器不会让您访问剪贴板的交易。然而，就像所有事情一样，有一个解决方法。
https://github.com/zeroclipboard/zeroclipboard

this is a js/flash plugin that lets you copy text to your clipboard.
(i believe you can use it for rich text.)
这是一个 js/flash 插件，可让您将文本复制到剪贴板。
（我相信您可以将它用于富文本。）
