无法使document.execCommand与复制文本一起正常工作 [英] cannot get document.execCommand to work properly with copying text
问题描述
这是我的代码:
function createTextArea() {
var t = document.createElement("textArea");
textArea = document.body.appendChild(t);
return textArea;
}
function copy(str) {
var textArea = createTextArea();
textArea.value = str;
textArea.select();
document.execCommand("Copy");
}
copy("hello")
现在,当我尝试粘贴时,放置在文本区域中的文本没有出现。有人知道我在做什么错吗?
Now, when I try to paste, the text I placed into the textarea is not appearing. Does anyone know what I'm doing wrong?
推荐答案
根据文档,您有错字。来自在Mozilla中进行富文本编辑有关执行命令
You have a typo according to documentatin. From Rich-Text Editing in Mozilla about executing commands
复制
将当前选择复制到剪贴板。必须在 user.js
首选项文件中启用剪贴板功能
。
copy
Copies the current selection to the clipboard. Clipboard capability must be enabled
in the user.js
preference file.
并查看这两篇文章:
如何配置Firefox以允许Javascript拦截从剪贴板粘贴的值?和
使用JavaScript复制到所有浏览器的剪贴板
And see those two posts: How do you configure Firefox to allow Javascript to intercept a value pasted from the clipboard? and Copy to Clipboard for all Browsers using javascript
因此,是否可以这样做似乎很成问题。
So, it seems very questionable if you can do that.
