Hi I have the following code...
I want to add in an if statement that checks to see if the number of items remaining is 0. If it is 0, I want it to say finished and the button be disabled / disappear.
Can anyone help?
TIA
Code:
<!doctype html>
<html>
<head>
<title>Loops</title>
</head>
<body>
<form id = "frmOne">
<table border="1" >
<p>Items Remaining: <a id="clicks">5</a></p>
<tr>
<th> Number One:</th>
<th> Number Two:</th>
</tr>
<tr>
<td> <Input Type="Text" Name="txtFirstNumber" Size="5" value=""> </td>
<td> <Input Type="Text" Name="txtSecondNumber" Size="5" value=""> </td>
</tr>
<tr>
<td colspan="2"> Totals: <textarea Name="totals" style="width: 400px; height: 300px;"></textarea></td>
</tr>
<tr>
<td colspan="2"> <Input Type="Button" Name="b1" Value="Add Numbers" onClick = calculate()> </td>
</tr>
</table>
</form>
<script>
var Totals = [ ];
var clicks = 5;
function calculate() {
var form = document.getElementById("frmOne");
var A = form.txtFirstNumber.value;
var B = form.txtSecondNumber.value;
Totals.push( A + " + " + B + " = " + (1*A+1*B) );
form.totals.value = Totals.join("\n");
form.txtFirstNumber.value = form.txtSecondNumber.value = "";
clicks -= 1;
document.getElementById("clicks").innerHTML = clicks;
}
</script>
</body>
