You're in the
dotnet jscript
group:Can't Copy Data To Clipboard
dotnet jscript:
code posted earlier for Pasting from the clipboard so I modified it for copy but it is not working (see code below). When I click on the btnCopyToClipboard I can see some processing going on but the text from the textbox is not being put on the clipboard? I tried changing the "txtHidden.focus()" to "innerHTML" but that also gave no data on the clipboard? Thoughts or suggestions? Wayne ==================================== Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load If Not IsPostBack Then btnCopyToClipboard.Attributes.Add("onclick", "CopyIt();return false;") Page.RegisterClientScriptBlock("copyroutine", _ "<script>function CopyIt()" & _ "{document.all.txtHidden.focus();" & _ "document.execCommand('copy');}</script>") End If End Sub

Thanks for the suggestion but this is on my development system which does
accept copy from other web sites so I don't think that is the issue.

What about that? Execing the command on document/body does apply to the current text selection, which has little to do to your hidden element … -- Serge

Again, thanks for responding. You are saying that the "document.getElementById("txtHidden").createTextRange().execCommand(....)" will select the text in that text box? Excuse my dumb questions but the workings of javascript really have me lost!

WW> You are saying that the
WW> "document.getElementById("txtHidden").createTextRange().execCommand(....)" will select the text in that text box? Not quite. I'm not sure for the textbox at all (have never checked that), but for the ordinary text that should definitely do the thing. "document.getElementById("txtHidden")" is just a slightly better approach to getting the element than "document.all.txtHidden", that does not make sense. "createTextRange" gives an object representing a piece of text which falls inside the element you are calling this function on. This text does not get selected, but it can be manipulated with. For example, you can retrieve this text as plaintext or HTML, or really select it, or execute any of the browser commands (see the IHTMLTxtRange interface in MSDN, or Text range object, for details). In your case, you would like to execute the copy-to-clipboard command, but not on the whole document (which has no selection and thus won't complete your request), and without selecting anything, but just applying "copy" to the chosen range. Well, here's a working sample for you, enjoy: <html> <input id="txtHidden" type="text" value="Hello, World!" style="display: none;" /> <button onclick='document.getElementById("txtHidden").createTextRange().execCommand("copy")'>Copy</button> </html> Tat's it. Just have no idea of how this goes with browsers other than ones based on MSHTML ;-) -- Serge
Thanks Serge;
I'll try applying that to my case.

I am back to the original problem - txtHidden is a textbox in an ASP.NET page. I cannot use the old <input..> tag. The problem seems to be how to select the text in an ASP.Net textbox in javascript. I'll do some more google searches to see if I can figure this out.

What does "View Source" say? -- Serg
