How to pass a parameter by URL to the JavaScript code on GAE?
Question
I'd like to pass a parameter in request URL to the JavaScript code on GAE environment.
For example, following URL was entered.
http://example.com:8080/hello?key=abc
The hello page was rendered with hello.py and hello.tmpl which are shown below respectively.
'''hello.py'''
key = self.request.get('key')
{# hello.tmpl #}
<html>
<div id="key">{{ key }}</div>
<script src="hello.js"></script>
</html>
In order to refer the key specified with URL in hello.js, the function can be written as following.
// hello.js
function() {
console.log($('#key').text());
};
It works well and meets my original request that a parameter was propagated from the URL to the JavaScript Code.
However, I felt like it's not a smart way. I used div tag as a buffer between URL and JavaScript code. Does anyone know any smarter way to do this?

You can use data extension instead of adding a div:
<body data-key='{{key}}'>
<...>
</body>
// hello.js
function() {
console.log($('body').data('key'));
};
