No. You need to understand the order things happen in: Python renders your HTML The web server delivers your HTML to a client browser The web browser runs the javascript in your HTML and updates the DOM You are asking "How do I look at a value from the DOM before the DOM exists". You can't. Work out a better way of doing what you are trying to do, eg: by using javascript to determine whether 'code here' is visible or not by working out what the value of the node would be in python before rendering it. Impossible things are not possible, no matter how nice the framework. Cheers Tom -- You received this message because you are subscribed to the Google Groups "Django users" group.
