我似乎无法让 checkbox.checked 工作,我有一个脚本可以更改基于 onclick() 的图像,但是我希望它根据是否选中复选框来更改它。我究竟做错了什么?此外,如果有人能够解决此问题,则复选框不会在 ie8 中检查

代码:
<script type="text/javascript">
function func()
{
var img1= document.getElementById("img1");
if(checkbox.checked)
{
img1.src = "images/" + "img1a.jpg";
img1.name = "off";
}
else
{
img1.src = "images/" + "img1.jpg";
img1.name = "on";
}
}
</script>

<form>
<p align="center">
<input type="checkbox" name="interest1" id="interest1" value="x">
