如何使用js粘贴文本行? [英] How to paste a text line using js?
问题描述
伙计们，我只是使用js的execCommand方法来做一些简单的事情来执行系统复制，删除等命令.
我做了两个文本区域，其中一个是我输入一些文本，然后单击按钮执行复制，剪切等命令.
问题:::: --------
在此粘贴按钮不起作用.就像我从一个文本区域复制一些文本一样，它没有粘贴到其他文本区域.
我也想只为textareas选择全部.就像如果光标在textarea1上并且如果我在selectAll按钮上单击一样，它应该只选择textarea1内容.目前，它正在选择整个页面的内容.
以下是我的代码
Well guys, i was just doing a simple stuff of executing system copy, delete etc. commands using execCommand method of js.
I have made two textareas, in one i am inputting some text and by hitting on the buttons i am executing copy, cut etc. commands.
Problems::::----
In this the paste button is not working. Like i am copying some text from one textarea, it is not pasting into other textarea.
Also I want to do select all for the textareas only. Like if cursor is on textarea1 and if I am hitting on selectAll button it should only select the textarea1 content. Currently it is selecting the whole page content.
Following is my code
<html>
<head>
<script language="javascript">
function doCopy()
{
document.execCommand('Copy',false,0);
}
function doPaste()
{
document.execCommand('Paste');
}
function doCut()
{
document.execCommand('Cut',false,0);
}
function doSelectAll()
{
document.execCommand('SelectAll',false,0);
}
function doDelete()
{
document.execCommand('Delete',false,0);
}
function doUndo()
{
document.execCommand('Undo',false,0);
}
function doUnselect()
{
document.execCommand('Unselect',false,0);
}
</script>
</head>
<body>
<div align="center">
input values : ---- <br>
<textarea align="left" id="txtArea" name="txtArea" style="width:300px;height:50px"></textarea>
<br>
<input type="button" id="btnCopy" name="btnCopy" value=" Copy " onClick="doCopy()" />
<input type="button" id="btnCut" name="btnCut" value=" Cut " onClick="doCut()" />
<input type="button" id="btnSelectAll" name="btnSelectAll" value=" Select All " onClick="doSelectAll()" />
<input type="button" id="btnPaste" name="btnPaste" value=" Paste " onClick="doPaste()" />
<input type="button" id="btnDelete" name="btnDelete" value=" Delete " onClick="doDelete()" />
<input type="button" id="btnUndo" name="btnUndo" value=" Undo " onClick="doUndo()" />
<input type="button" id="btnUnselect" name="btnUnselect" value=" Undo " onClick="doUnselect()" />
<br>
Manipulate <br>
<textarea align="left" id="txtArea1" onpaste="alert('yes');" name="txtArea1" style="width:300px;height:70px" ></textarea>
</div>
</body>
</html>
这些东西用于IE9.
