hmm, not sure about that subject line, but here goes....
I am altering a javascript rich-text editor which uses the IE
proprietary execCommand methods.
I wish to add a number of instances of the editor to a page - have thge
following code for an initialisation for each editable iframe that us
used for rich text editing:
iframes are named: iBody_1, iBody_2 and so forth
hidden textareas that contain the database text to be edited are named:
contentBody_1, contentBody_2 and so forth.
function init()
{
// number of instances of editor on page
var instances = 2;
// counter
var i;
// set design mode,a nd place database text into iframe for each
instance on page
for(i=1; i<=instances; i++)
{
// format iframe name
var i_name = 'iBody_'+i+'';
i_name = i_name.toString();
// THIS NEXT LINE BREAKS THE SCRIPT
i_name.document.designMode = 'On';
// fomat hidden textarea (containing document text to be edited)
name
var textarea_name = 'contentBody_'+i+'';
// get the text from this textarea
innerTmp = document.forms[0].elements[textarea_name].value;
// format command for setTimeout method
var command = i_name+".document.body.innerHTML = innerTmp;"
// place this text into the iframe, timeout is to give the
scripot time to perform these actions
setTimeout(command,500);
}
}
The error I get from IE6 is : "document is null or not an object" for
the line which sets the desing mode to on. I can hardcode the iframe id
into the line and the script will execute without error. I can comment
the line and the script will execute without error (only the iframe text
is not editable, as designMode has not been set!)
What is stopping a variable name (i_name) from working successfully on
the design mode line, as opposed to a hardcoded value?
Am I making sense?
