"document is undefined": document.getElementById("map_canvas")

[ifido...@gmail.com]

Hi everyone,

Recently I have started to make something with Ubiquity. I have a line
like this:

- :: document.getElementById("map_canvas")

which is suppose to get the this:

- :: <div id="map_canvas"></div>

inside of the preview box. But, an error pops up saying: "An exception
occurred while loading code.ReferenceError: document is not defined."
Any ideas to how to fix this or a workaround?

Thanks,

Mike

Try Application.activeWindow.activeTab.document instead.

If that code is executed from the command (rather than from within the
preview HTML) it won't work. Commands are run within a sandbox which has
no document. I'd suggest using jQuery to deal with the DOM - in your
example, you'd use:

jQuery("#map_canvas", previewBlock).get(0)

to get the DOM node. Where previewBlock is the name of the first
argument in the preview() function in your command.

An alternative way would be to insert the Javascript into the preview
HTML, so it runs within that context. That may be a bit messy however,
as currently there's no easy way to separate the preview HTML into its
own file.

Hope that helps.

That will get the document for the active tab - but what is wanted is
the document for the preview.

Ah, thank you for helping me. I have tried both of the methods you
guys suggested. The one with the tab is not what I had in mind, and
this one:

- :: jQuery("#map_canvas", previewBlock).get(0)

returns "undefined" for some reason.

Thanks,

Mike
