javascript ok cancel pop-up button

I've tried a lot of things, but still can access a .js file from inside a form: please, can anyone tell me how it can be done?

this is what I am trying to call:

 <script type="text/java开发者_运维技巧script">
    if (confirm("Press 'OK' to leave, or 'Cancel' if you want to stay: "))
    {         
       window.location="http://google.com";
    }
    else
    {         
      <a href="javascript:history.go(-1)">Go back</a> 
    }
  </script>

this is how I've been trying to call:

<input type="BUTTON" value="Back to Main Page" onclick= ??? >

Thank you.

var answer = confirm ("Press Ok to leave. Cancel to stay.")
   if (answer)
window.location="http://google.com"
   else
window.location="http://www.mysite.com/"

You are adding HTML code inside of your JavaScript code. You need to separate them. Something like:

document.write('<a href="javascript:history.go(-1)">Go back</a>');

would do the trick.

You need to make your code into a javascript function, like this

function sayHello()
{
  alert('hello');
}

And in the button html:

<input type="BUTTON" value="Back to Main Page" onclick="javascript: sayHello();" >
