Bottlepy - How To Access Bottle Arguments {{var}} From Javascript?

I'm developing a template that will be included into a larger template, and for some reason the template is not accepting any arguments in Javascript. Everything is fine if the ar

Solution 1:

As @dandavis pointed out in the comment, the proper way to reference the argument in javascript is to put it in a quote:

test.tpl: 

<p>from html: {{arg}}</p><scripttype="text/javascript">window.alert("from script "+"{{arg}}");
</script>

Output:

from script somevalue

Without the quotation mark, what JavaScript actually sees is a string followed by a variable called some value, which is not cannot be concatenated with a string literal. This is how my original code looks like to the browser:

window.alert("from script " + some value);

which is wrong.
