Some of them are working fine. It makes me feel good. Well, I have got an very important question, anyway. Here is my mission: quote: User can input how many marks they have.

Do you know what I mean? This cal fanction loop up to max times. User input mark into text box. But what I am wondering is how to access to those input data???! Would you know any tips? Any help will be great. Hiroki Kozai

For example, at the start of the write loop in your cal function, wirte a form tag with a new form name and at the end have a submit (or some other) button that calls a different function to evaluate what the user has entered. You can access those values using newformName.inputName[i].value. The input boxes on the new form will all have the same name, so you will need to find out how many of them there are by getting the length of the array of the form boxes. For example, if the input boxes in the new form are called "marks", you can find out how many of them there are with newformName.marks.length and then looping through that array. I haven't actually tried to do this, but it should work. Maybe some of the real gurus can chime in here. Few problems in life can't be solved by chocolate

Hi, guys. How are you?
I am coding JavaScript since this morning. Better than yesterday.
Some of them are working fine. It makes me feel good.

Well, I have got an very important question, anyway. Here is my mission:

quote:
User can input how many marks they have. Then input text box appers according to the user input number. JS add all marks up then show the avarage of marks.

I succeed showing input box according to user input data. Please see here

And code is:

code:

<html>

<head>

</head>

<body>



<form name="theForm">

<p>How many mark do you have?

<input type="text" name="num" onBlur="cal()">

</p>

</form>



<script type="text/javascript">

 function cal(){

  var max = document.theForm.num.value;

  for(i=1; i<=max; i++){

    document.write("Enter the mark" + i + ": ");

    document.write('<input type="text" name="mark">');

    document.write("<br />");

    }

}

</script>



</body>

</html>

But from this point, I am confused how to add each mark. Do you know what I mean? This cal fanction loop up to max times. User input mark into text box. But what I am wondering is how to access to those input data???! Would you know any tips? Any help will be great.

A much easier way to do this would be to use the prompt function:

code:

var mark = prompt('Enter the value of mark number' + i);
