<script type="text/javascript">
function buttonCheckForm_onclick()
{
var form1 = document.myForm;
if(form1.textName.value == "" || form1.textAge.value == "")
{
alert("PLease complete the form");
if(form1.textName.value == "")
{
form1.textName.focus();
}
else
{
form1.textAge.focus();
}
}
else
{
alert("Thanks for completing the form" + form1.textName.value);
}
}
function textAge_onblur()
{
var textAge = document.myForm.textAge;
if (isNaN(textAge.value) == true)
{
alert("Please enter a valid age");
textAge.focus();
textAge.select();
}
}
function textName_onchange()
{
window.status = "Hello" + document.myForm.textName.value;
}
</script>
</head>
<body>
<form action="" name="myForm">
Please enter the following details:
<p>
Name:
<br/>
<input type="text" name="textName" onchange="textName_onchange()" />
</p>
<p>
<input type="text" name="textAge" onblur="textAge_onblur()" size="3" maxlength="3" />
</p>
<p>
<input type="button" value="Check Details" name="buttonCheckForm" onclick="buttonCheckForm_onclick()" />
</p>
</form>
</body>
</html>

首先，函数后跟{而不是[，其次，判断用==而不是=。谢谢
