I have an HTML page, In the variable schedule has sequential decimal number in seconds.
My purpose is create a function to convert all these numbers in time using JavaScript/jQuery, but i could not understand, how can I invoke my function to convert all items?
<html>
<body>
// Jinja code
{% for item in schedule %}
{{ convertDecimal_to_time(item.someDecimal) }}
{% endfor %}
</body>
</html>
<script>
covertdecimal_to_time(input_number){
.....
return time;
}
</script>

The Jinja code runs on your server. The Javascript runs on the client's browser.
You can't call a javascript function in a Jinja for-loop, because those two things happen at completely different times, on different machines.
The best approach for this scenario is to write a Python function, not a Javascript function, and run it as a filter. You can add a custom filter to the template engine.
