call javascript function flask
In order to call a JavaScript function from Flask, you can follow these steps:
- Create the JavaScript function in your HTML file, for example:
function myFunction() {
// Your code here
}
- Create a route in your Flask app that will be triggered to call the JavaScript function, for example:
@app.route('/call_js_function')
def call_js_function():
# Your code here
- In the route function, you can use the
render_template
function to render a template that contains the JavaScript function call, for example:
return render_template('call_js_function.html')
- In the
call_js_function.html
template, you can call the JavaScript function, for example:
<!DOCTYPE html>
<html>
<head>
<script>
myFunction();
</script>
</head>
<body>
<!-- Your HTML content here -->
</body>
</html>
- When the
/call_js_function
route is accessed, it will render thecall_js_function.html
template and trigger the JavaScript functionmyFunction()
.
