JavaScript/HTML problem

hellomott0

Hello there,

I have a problem in JavaScript/HTML. For example, there is two boxes, in one you enter 2 and in the other you enter the number 3. How would I make them multiply and show the answer in a textarea beneath the boxes.

So, heres another example:

Name: (enter name here)
Price of water: (enter price)
Lt. of water: (enter litres of water)

Calculate (this is a button calling the function)

***This is where a textarea box is***

So when the person enters the name, price and litres of water how would i get that results to appear in the textarea?


Thanks in advance

Sounds suspiciously like homework.

Call a Javascript function akin to the following from the Calculate button:

function calculate()
{
   var nm = document.getElementById('name').value;
   var pr = document.getElementById('price').value;
   var li = document.getElementById('litres').value;
   
   document.getElementById('result').value = "Name: " + nm + "\r\nResult:" + (pr * li);
}

No worries - that's very basic but a starting point..

.. you'll need to do validation and the like yourself.
