Uncaught TypeError: Cannot read property 'setData' of undefined
Question
i wrote Javascript that copies the data from textbox to the clipboard:
TextBox:
<asp:TextBox ID="contNoTxtBox" runat="server" Width="182px" style="height: 22px"></asp:TextBox>
Javascript:
function CopyToClipBoard()
{
var text = document.getElementById('contNoTxtBox').innerHTML;
window.clipboardData.setData('Text', text);
}
and i call it in HTML button the following way:
<input id="CopyButton" type="button" value="Copy" onclick="CopyToClipBoard()" /><br />
However i get the following error:
Uncaught TypeError: Cannot read property 'setData' of undefined

Referring to http://help.dottoro.com/ljctuhrg.php your
window.clipboardData.setData('Text', text);
is compatible with InternetExplorer only. There are alternative ways to implement this using Chrome etc. shown in their examples.

Aspx code:
<head>
<script language="javascript" type="text/javascript">
function pasteContent() {
document.getElementById('ClipboardContent').value = document.execCommand('copy');// window.clipboardData.getData('Text');
return (true);
}
var elem3 = document.getElementById("elem");
document.addEventListener("click", function () {
document.getElementById("demo").innerHTML = "Hello World";
});
elem3.addEventListener('copy', function (e) {
e.preventDefault();
if (e.clipboardData) {
e.clipboardData.setData('text/plain', 'custom content from click');
} else if (window.clipboardData) {
window.clipboardData.setData('Text', 'custom content from click');
}
});
</script> <script runat="server">
protected override void OnInit(EventArgs e) { Page.ClientTarget = "uplevel"; base.OnInit(e);
}
</script>
</head>
<body>
<asp:Button ID="ReloadCtl" runat="server" Text="Paste" OnClick="ReloadCtl_Click"
OnClientClick="return pasteContent();" />
<asp:HiddenField ID="ClipboardContent" runat="server" ClientIDMode="Static" /> </body>
C# Code:
protected void ReloadCtl_Click(object sender, EventArgs e)
{
if (!string.IsNullOrEmpty(this.ClipboardContent.Value))
{
DataTable dt1 = DataMapper.GetDataTable(this.ClipboardContent.Value, false);
}
}
