How to Clear Text Area from Javascript

[mayerh2]

I need to reset (clear) the text area of Rad Editor (contained in a MOSS template) from Javascript.

<radE:RadHtmlField ID="RadEditorText2E" FieldName="AMCText2XHTML" runat="server" AllowFonts="False" AllowHtmlSourceEditing="True" DisplayHeight="400px" DisplayWidth="430px" DisableCustomStyles="True"/>

I have found this info in a thread:
<rade:radEditor id= "RadEditor1" runat= "server"></rade:radEditor>
    var editor = <%=RadEditor1.ClientID %>; //get a reference 
     editor.SetHtml("");

But this does not work with MOSS - how could it -
<%=RadEditorText2E.ClientID %> returns a string. How can I get the necessary reference. And what kind of object does the reference point to. I can get a reference to the text area HTML element: <textarea style='display:none' id='RadEContentHiddenTextareactl00_PlaceHolderMain_TextPanel2E_RadEditorText2E_ctl00' .....
But clearing the value of this text area does not work.

Thank you in advance for help.

Hi Hugo,

You can use an alternative method to get a reference to the editor client object. Each editor object on the page is included in a JavaScript array, called RadEditorGlobalArray. Here is some sample code to help you:

<script type="text/javascript">
function test()
{
    if (typeof(RadEditorGlobalArray)!="undefined")
    {
        for(i=0;i<RadEditorGlobalArray.length;i++)
        {
            var editor = RadEditorGlobalArray[i];
            //alert(editor);
            editor.SetHtml("");
        }
    }
}
</script>

The editor.SetHtml("") function will clear the editor contents

Hi Lini,
this was exactly the information I was searching for. Since I have the ClientID of the RadEditor, using editor.Id I can locate the editor instance I want to clear.

Thank you so much for this prompt help.
