help with javascript & HTML DOM
hi,
I have a form that, when a button is clicked, it sends the info to a js function that is supposed to add the number "3" to the textbox on the form. Can someone please tell me what I should do to make it work... Code:
<head>
<script language="javascript">
function fnNum(numText)
{
var x = document.myForm.num.value
x = x + ""
document.myForm.num.value=x+numText
}
</script>
</head>
<body>
<form id="myForm">
<input type="text" name="num">
<button type="button" id="myButton" value="3" onClick="fnNum(this.value)">3</button>
</form>
</body>
