I have a problem. Flask application respond a 404 not found at this .css url.
How can I write this jinja code in javascript file ?
{{ url_for('static', filename='assets/css/themes/') }}
Javascript file
var setColor = function (color) {
var color_ = (App.isRTL() ? color + '-rtl' : color);
$('#style_color').attr("href", "assets/css/themes/" + color_ + ".css");
}
Jinja 2 is expected to template html files only : unless you put your script in the html and template it, which I would discourage, you cannot use templating directly in your javascript static file.
You can however template a part of the html that will contain the link, for example in a data attribute, or in a shared variable, to be recovered by javascript.
In the page
<div id="mydiv" data-myurl='{{ url_for('static', filename='assets/css/themes/') }}'> </div>
In javascript
$('#style_color').attr("href", $("#mydiv").data('myurl'))
