Cannot activate Javascript within the HTML page. This HTML page contains both Python and Javascript script. This HTML page is generated by a Python script.
When a user enter a non-numeric value in the text box, an alert message will prompt the user, and the non-numeric value is automatically deleted from the text box. This Javascript code does work if it contains only Javascript, but when it is within the code that Python generated, and I put in a non-numeric value, it said
"error on page" at the bottom left hand corner.
The code, below do not have a <form> <body> and <html> when View --> Source is done on Internet Explorer because the <form> <body> and <html> header are generated from another code.
