Greasemonkey \JavaScript复制到剪贴板按钮 [英] Greasemonkey\JavaScript Copy to Clipboard button

问题描述

我正在尝试编写一个JavaScript脚本来添加到添加按钮后的按钮上。该按钮的onClick应该将父母元素文本复制到键盘。我已经看到很多例子，将已经选择的文本复制到剪贴板中，例如：

 < SCRIPT LANGUAGE =JavaScript > 
<！ - 开始
函数copyit（theField）{
 var selectedText = document.selection; 
 if（selectedText.type =='Text'）{
 var newRange = selectedText.createRange（）; 
 theField.focus（）; 
 theField.value = newRange.text; 
} else {
 alert（'Alert：Select the text in the textarea then then click on this button'）; 
} 
} 
 //结束 - > 
< / script> 
< input onclick =copyit（this.form.text_select）type =buttonvalue =单击此处复制突出显示的文本name =copy_button> 
  

找到 here 。

我也发现你可以在输入元素中选择文本。我尝试过将这两种技术以及许多其他方法结合起来，但还没有可行的解决方案。我甚至不知道为什么上面的代码复制到剪贴板。有没有人有这个解决方案？如果您花时间阅读完整的文章，作者指出这不适用于Firefox ... b
实际上，我认为它甚至不能用于IE，因为它与剪贴板没有任何关系！

有一种使用Flash的技术，因为默认情况下，出于安全原因，Firefox禁止剪贴板访问。

否则，传统的复制方式是：

$ p $ code> var tc = textToCopy.replace（/ \\\
\\\
/ g，'\\\
'）;
if（window.clipboardData）// IE
{
window.clipboardData.setData（Text，tc）;
}
else
{
unsafeWindow.netscape.security.PrivilegeManager.enablePrivilege（UniversalXPConnect）;
const clipboardHelper = Components.classes
[@ mozilla.org / widget / clipboardhelper; 1]。
getService（Components.interfaces.nsIClipboardHelper）;
clipboardHelper.copyString（tc）;
}

启用复制后（给定网站）。

I am trying to write a JavaScript script to add to greasemonkey that adds a button after an element. The onClick for this button should copy the parents element text to the keyboard. I have seen plenty of examples that copy already selected text to the clipboard such as this:

    <SCRIPT LANGUAGE="JavaScript">
    <!-- Begin
    function copyit(theField) {
    var selectedText = document.selection;
    if (selectedText.type == 'Text') {
    var newRange = selectedText.createRange();
    theField.focus();
    theField.value = newRange.text;
    } else {
    alert('Alert: Select The text in the textarea then click on this button');
    }
    }
    // End -->
    </script>
    <input onclick="copyit(this.form.text_select)" type="button" value="Click Here to Copy the Highlighted Text" name="copy_button">

Found here.

I have also found that you can select text in input elements. I have tried combining both techniques, as well as many others with no viable solution yet. I am not even sure why the code above copies to the clipboard. Does anyone have a solution to this?

解决方案

If you took the time to read the full article, the author states this doesn't work for Firefox...
Actually, I think it doesn't even work for IE, as it does nothing related to the clipboard!

There is a technique using Flash, because by default, Firefox inhibits clipboard access for security reasons.
Otherwise, the classical way to do copy is:

var tc = textToCopy.replace(/\n\n/g, '\n');
if (window.clipboardData) // IE
{
  window.clipboardData.setData("Text", tc);
}
else
{
  unsafeWindow.netscape.security.PrivilegeManager.enablePrivilege("UniversalXPConnect");
  const clipboardHelper = Components.classes
      ["@mozilla.org/widget/clipboardhelper;1"].
      getService(Components.interfaces.nsIClipboardHelper);
  clipboardHelper.copyString(tc);
}

after enabling copy (for a given site).
