Why does my code under JavaScript won't work if I try to write it under HTML?

<html> <head> <title>Form</title> </head> <body> <form onsubmit="return validate()" method="post"> Number: <input type="text" name="num1" id="num1" /><br /> Repeat: <input type="text" name="num2" id="num2" /><br /> <input type="submit" value="Submit" /> </form> <script> function validate() { var n1= document.getElementById("num1"); var n2= document.getElementById("num2"); if (n1.value!="" && n2.value!="") { if (n1.value == n2.value) { return true; } } alert("The values must be equal and not blank); return false; } </script> </body> </html> That's how I did it. I added the script tag under the body, and that's where I wrote my code for JavaScript. It works in the Code Playground, but when I tried to do it on my notepad it doesn't work :<

This is html code. It will not work on notepad. You have to save it with .html extension file then open it on browser. It will work.

in form, onsubmit, don't return validate(), just validate() <form onsubmit="validate()"> After pasting in notepad, choose Save As, choose file type All Files, name file index.html with file extension html. Now in your desktop or folder, you see a HTML file which will be opened by browser.
