When I render a page using the Django template renderer, I can pass in a dictionary variable containing various values to manipulate them in the page using {{ myVar }}.
Is there a way to access the same variable in JavaScript, <script></script> (perhaps using the DOM; I don't know how Django makes the variables accessible)? I want to be able to look up details using an Ajax lookup based on the values contained in the variables passed in.
The {{variable}} is substituted directly into the HTML. Do a view source; it isn't a "variable" or anything like it. It's just rendered text.
Having said that, you can put this kind of substitution into your JavaScript.
<script type="text/javascript">
var a = "{{someDjangoVariable}}";
</script>
This gives you "dynamic" JavaScript code.
For a dictionary, you're best off encoding to JSON first. You can use simplejson.dumps() or if you want to convert from a data model in App Engine, you could use encode() from the GQLEncoder library.
