    Question on math.pow function

    I am working on a problem and have been trying for several hours to get this to work. Basically, the form language was provided - I need to input JS code to produce the square root of the number that is inputted by the user and display it on the form.

    The form produces fine - the program not computing a result is my issue. Any help is appreciated. Code I have produced is as follows:


    Code:
    "http://www.w3.org/TR/html4/strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">

<script language="JavaScript">
function math.pow(number,2)
</script>

<form name="square" action="#">
<input type="text" name="number">
<input type="button" value="compute" onclick="process()">
<input type="text" name="result">
</form>
</html>

      You have no function named process.

          I made some edits, including a process function, however the code still does not work.

          I am new to JS - any help is appreciated.

          Code:
          <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN"
"http://www.w3.org/TR/html4/strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<script language="JavaScript">
<!-- 
function process()
{
   var formObj = document.getElementById();
   var number = formObj.number.value;
   {
      formObj.number.value = Math.pow(number,2); break;
   }
} 

//  -->
</script>
</head>
<form name="square" action="#">
<input type="text" name="number">
<input type="button" value="compute" onclick="process()">
<input type="text" name="result">
</form>
</html>

              You didn't tell getElementById which id to get. Also, your form has no id. So you won't be able to get it anyways unless you give it one.

                  I need to input JS code to produce the square root of the number that is inputted
                  Math.pow(x, 2) produces the square of x, not its square root (that would be Math.sqrt()).
