clear editor1 using javascript

Reply Quote

Is there a way to clear the editor using javascript? I have the following javascript but its not working. Thanks for any help.

function ClearEmailTextbox()

{

document.getElementById('ctl00$ContentPlaceHolder1$Editor1').value = "";

}

Below is the vb.net codebehind

Editor1.Attributes.Add("OnFocus", "ClearEmailTextbox()")

Dear lonnie,

Please try the following code:

function clearEditor()
   {
    // get the cute editor instance
    var editor1 = document.getElementById('<%=Editor1.ClientID%>');
    // Set the editor
    editor1.setHTML("");
   }

Thank you for asking

Thanks Eric for your response. I'm still having a little trouble in running the javascript. Here's what the client would like to do.

The client would like a "Click here to type message" in the editor when it first appears. When the user clicks the editor they want the message to disappear. The editor does not appear when the page loads. It will only display when the user selects the required fields.

I'm using the following line of code to set an attribute for the editor but I don't believe onfocus is a method of the editor

Editor1.Attributes.Add("onFocus", "clearEditor()")

Thanks again for all your help,

Lonnie
