  • 0

I have a question on as why my code won’t execute correctly, I need to be as basic as possible when applying these commands. I hit the convert button and nothing, did I need a command for that too? It is for homework, I have been dabbling at it for hours.

EDIT***

  <html>
<head>

<script type="text/javascript">
<script>
function Convert()
onclick= document.getElementById('Convert')

    var years = document.getElementById("year").value;
    var days = document.getElementById("days").365.25 * years;
    var hours = document.getElementById("hours").(365.25 * 24) * years;
    var minutes = document.getElementById("minutes").(365.25 * 24 * 60) * years;
    var seconds = document.getElementById("seconds").(365.25 * 24 * 60 * 60) * years;

document.getElementById('days').value = days;
document.getElementById('hours').value = hours;
document.getElementById('minutes').value = minutes;
document.getElementById('seconds').value = seconds;



});
    </script>
  </head>
  <body>
    Years: <input type='text' id='years' /> 
    <button id='Convert'onclick= "Convert()" value= "Convert"/> Convert </button>

    Days: <input type='text' id='days' /> 
    Hours: <input type='text' id='hours' /> 
    Minutes: <input type='text' id='minutes' /> 
    Seconds: <input type='text' id='seconds' /> 
  </body>

    A few things (hopefully they get you going again):

    1. You never call your function. Add an onClick handler to your button.
    2. You are prompt ing fixed strings instead of variables.
    3. You’ll have to extract the data from the input in your JavaScript. You could use document.getElementById() for that.

    Note, I could give you the answer, but homework and learning is all about figuring stuff out by yourself. Get going with my tips and see what you can come up with. Edit your question with what you got if you get stuck again.

    Okay, next round. What you’ll have to do in your Convert function:

    1. First, fetch the information from the form like this:

       var years = document.getElementById("year").value;

    2. Then, do you calculations:

       var days = 365 * years;

    3. Finally, write back the results:

      document.getElementById("days").value = days;

    Some extra tips:

    1. You are missing a space between id='Convert' and onclick
    2. Install a debugger like Firebug for Firefox.

    Good luck!

    Round three; here is the complete answer. Just try to understand what is going on. It is usually good to learn from working examples.

    Extra stuff I found:

    1. An extra <script> tag in your html
    2. The function definition is wrong, it should be function foo() { }

    —— complete answer follows —–

    <html>
<head>

<script type="text/javascript">

// Declare a function called Convert()
function Convert() {
    // Get the value of what the user entered in "years"
    var years = document.getElementById("years").value;

    // Calculate all the other values
    var days = years * 365.25;
    var hours = days * 24;
    var minutes = hours * 60;
    var seconds = minutes * 60;

    // Write the results in the input fields    
    document.getElementById('days').value = days;
    document.getElementById('hours').value = hours;
    document.getElementById('minutes').value = minutes;
    document.getElementById('seconds').value = seconds;
}
</script>
</head>
  <body>
    Years: <input type='text' id='years' /> 
    <!-- define a button that will call Convert() when clicked on -->
    <button id='Convert' onclick= "Convert()" value="Convert">Convert</button>

    Days: <input type='text' id='days' /> 
    Hours: <input type='text' id='hours' /> 
    Minutes: <input type='text' id='minutes' /> 
    Seconds: <input type='text' id='seconds' /> 
  </body>
