Uncaught ReferenceError: < function> is not defined at HTMLInputElement.onclick

I am trying to call a simple javascript function from my html page. The javascript function will decrypt using the lib.js file and the same is alerted.

Uncaught ReferenceError: decryptfun is not defined
at HTMLInputElement.onclick (test.html:18)

The below is the only file I use (along with other dependent library files).

<!DOCTYPE html>

<html>

<head>

<script type=text/javascript src=lib.js>

function decryptfun() {

    var pass = hjubjbjhdgyuwj;

    var encrtoken = abcdefghijklmn;



    var p = lib.decrypt(encrtoken, atob(pass));

    }

    alert(p);

</script>

</head>



<body>

<h1>Decrypt Operation</h1>

<input type=button onclick=decryptfun() value=Click>

</body>

</html>

I tried other suggestions provided for the same type of issue at Stackoverflow but I was not successful. Can anybody help me out in locating the cause of the issue ?

Your error is because you have defined your function inside:

<script type=text/javascript src=lib.js>

the correct way is to close that script tag first like so:

<script type=text/javascript src=lib.js></script>

and then defining the script tag again to define the function like so:

<script>

function(){

    //body of function

};

</script>

<script type=text/javascript src=lib.js></script>

<script>

  function decryptfun() {

    var pass = hjubjbjhdgyuwj;

    var encrtoken = abcdefghijklmn;



    //var p = lib.decrypt(encrtoken, atob(pass)); //USE THIS IN YOUR CASE

    var p = test; //just for example

    alert(p);

  }

</script>

<h1>Decrypt Operation</h1>

<input type=button onclick=decryptfun() value=Click>
