You don't want to write JavaScript? Me, too. But, Let me handle it with Python.

import flask
from jsrope import Element, Flow, Switch, Int, For, Return, Function, If, true, false, Ajax, Util
from jsrope.util import substitute, negative, jquery3_script
app = flask.Flask(__name__)
@app.route("/")
def main():
input_box = Element.by_id("name_input")
p = Element.by_tag("p")
number = Int("num")
i = Int("i")
is_prime = Function("is_prime", {"num": None},
Flow(For(substitute(i, 2), (i < (number ** 0.5)).to_int() + 1, i.iadd(1),
Flow(If(negative(number % i), Flow(Return(false))))
), Return(true)
)
)
input_box_event = input_box.on("keyup",
Flow(Ajax("/", {"method": "GET", "data": {"data": input_box.get_value()}},
done=Util.alert(input_box.get_value())),
Switch({is_prime(input_box.get_value().to_int()): p.change_inner_html("prime"),
"else": p.change_inner_html("not prime")})
)).prettify()
return flask.render_template_string("""
<input id="name_input" type="text" style="width: 300px; height: 300px">
<p>inner</p>
{{ jquery3_url | safe}}
<script> {{ sc | safe }} </script>""", jquery3_url=jquery3_script, sc=Flow(input_box_event, is_prime.prettify()))
app.run(port=8888)Then this will return
<html><head></head><body><input id="name_input" type="text" style="width: 300px; height: 300px">
<p>prime</p>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.4.1/jquery.min.js"></script>
<script> $('#name_input').on('keyup', function(e) {
$.ajax({
url: "/",
method: "GET",
data: {
'data': $('#name_input').val()
}
}).done(alert($('#name_input').val()));
if (is_prime(parseInt($('#name_input').val()))) {
$('p').html('prime')
} else {
$('p').html('not prime')
}
});function is_prime(num) {
for (let i = 2;
(parseInt((i < num ** 0.5))) + 1; i += 1) {
if (!(num % i)) {
return false
}
};
return true
} </script></body></html>Instllation
Install with pip
$ pip install jsrope
Basic Usage
Don't forget to load jQuery.
You can use Element to select element.
You can find element by id, css_selector or tag.
from jsrope import Element
Element.by_id("element_id") # > $('#element_id')
# Same as Element.by("id", id)
Element.by_css_selector("input.input_numer") # > $('input.input_numer')
# Same as Element.by("css_selector", selector)
Element.by_tag("input") # > $('input')
# Same as Element.by("tag", tag)Others gonna be written in the future.
In End
Note this: Writing code by yourself is always the best way.
