How do I get the data from a html script tag into my python function?

I am trying to get the data that I have stored inside of a script tag in my html file to my python file so that I can use it in a python function, does anyone have any idea how I could achieve this? Here's my html code:

<textarea id="rendezook" class="rendezook"></textarea>
<button onclick="get_text();">Valider</button>
<script>
    function get_text() {
        var x = document.getElementById("rendezook")
        location.href = "/validate_comment?rendezook=" + encodeURIComponent(x.value);
        console.log(x.value)
    }
</script>

And then this is my python file:

@app.route('/validate_comment')
def validate_comment(item_id=None):
    print("test")
    print(request.args.get("rendezook"))
    print("test2")
    return redirect(url_for('msr_edit', item_id=72))

test and test2 are not getting printed so it is not entering the function.

The easiest way is to just use a form that's submitted via a GET request:

<form action="/validate_comment">
  <textarea name="rendezook" class="rendezook"></textarea>
  <button type="submit">Valider</button>
</form>

This will result in an URL like /validate_comment?rendezook=some_value_here, so you can access it via request.args (as it looks like you're using Flask):

@app.route('/validate_comment')
def validate_comment():
    print("yeet", request.args.get("rendezook"))
    return redirect(url_for('msr_edit', item_id=72))

Based on comments, if you're unable to use a form for some reason, then:

<textarea id="rendezook" class="rendezook"></textarea>
<button onclick="test()">Valider</button>
<script>
function test() {
    var x = document.getElementById("rendezook");
    location.href = "/validate_comment?rendezook=" + encodeURIComponent(x.value);
}
</script>

EDIT 2

Here's a minimal example that provably works :)

from flask import request, Flask

app = Flask(__name__)


@app.route("/validate_comment")
def validate_comment(item_id=None):
    x = request.args.get("rendezook")
    return f"you said {x}"


@app.route("/")
def index():
    return """
<textarea id="rendezook" class="rendezook"></textarea>
<button onclick="get_text();">Valider</button>
<script>
    function get_text() {
        var x = document.getElementById("rendezook")
        location.href = "/validate_comment?rendezook=" + encodeURIComponent(x.value);
        console.log(x.value)
    }
</script>
"""


if __name__ == "__main__":
    app.run()
