#187875 - MyFirstJavascript calculator!! Responding to: ???'s previous message |
Hi Per,
So have been spending some time on the net trying to learn how to say "HelloWorld" in JS. Looks not very difficult as I could write the code below rather fast ( OK adapted it from an example - ). I now want to bring in a Option button for English / Metric units and based on the selection do the relevant calculation. I am sure thats going to be possible too ??
<html>
<head>
<title> Fluid Power Calculator </title>
<script language="javascript" type="text/javascript">
function findvelocity(){
a=Number(document.calculator.number1.value);
b=Number(document.calculator.number2.value);
c=((a*1000/60)/ ((b/10)^2 *0.785))*10;
document.calculator.total.value=c;
}
</script>
</head>
<body>
<!-- Opening a HTML Form. -->
<form name="calculator">
<p>
<!-- Here user will enter 1st number. -->
Flow (lpm) : <input type="text" name="number1">
</p>
<p>
<!-- Here user will enter 2nd number. -->
Pipe ID (mm): <input type="text" name="number2">
</p>
<p>
<!-- Here result will be displayed. -->
Velocity ( mm/sec): <input type="text" name="total">
</p>
<!-- Here respective button when clicked, calls only respective artimetic function. -->
<input type="button" value="CALCULATE" onclick="javascript:findvelocity();">
</form>
</body>
</html>
For those not very familiar with HTML : To try the code, just copy paste the code into notepad and save it as a html file. Double click and it opens in a IE9 browser ( or any browser ?)and even calculates !! Raghu |
