Sending a javascript variable to python using forms

Question

Suppose I have created a form

<form action=" " method="POST">
<input type="text" name="xyz">
<input type="text" name="abc">
<button type="submit" >submit</button>
</form>

Using this I can access the values with the name "xyz" and "abc"

if request.method == "POST":
 val1 = request.form['abc']
 val2 = request.form['xyz']

But I also want to access a javascript variable using the same form. Since javascript variable has no identifier as like <input> has 'name', So is there any way to do so?

• Ouroborus: Use javascript to populate a hidden (type="hidden") form field with the variable's value.

Answer 1

If you want to pass a JavaScript variable to python using the form you can add an input field of type hidden with the value of the is variable (you can set it from JavaScript using document.getElementBy... functions)
