我已经阅读了几个示例，但仍然无法使其正常工作。我只是想通过单击复选框使 DIV 可见和不可见。我是否正确编码了javascript？
<html xmlns="http://www.w3.org/1999/xhtml">

<title>SimpleSample - Hidden Div</title>
</head>
<script type="text/Javascript">
function showhideDiv1() {
if (document.getElementyById('div1').style.display = "none") {
//show the div:
document.getElementById('div1').style.display = "block";
}
else {
//hide the div:
document.getElementById('div1').style.display = "none";
//clear the form:
//document.getElementById('myform').reset();
}
}
function showhideDiv2() {
if (document.getElementyById('div2').style.display = "none") {
//show the div:
document.getElementById('div2').style.display = "block";
}
else {
//hide the div:
document.getElementById('div2').style.display = "none";
//clear the form:
//document.getElementById('myform').reset();
}
}
</script>
