我不确定你是否可以做到这一点，但如果不能，如果可能的话，请为我提供一个简单的解决方法。 我希望用户选择一个img（"牛仔"或"巨人"的id）。 我想获取这些的值（都是"一"），并将其返回到 id "场景"中。 除了这部分之外，其他一切都有效，我有一种感觉，你不能这样做。 所以任何建议都会被折旧！
<script type="text/javascript">
//this is the user id session stored as a javascript variable
var userid = "<?=$id?>";
function bigimg(x) {
var myDate = new Date(); // Your timezone!
var myEpoch = myDate.getTime()/1000;
var deadline = '1344700055.000';
//determines if user was on time..if not on time hover enlarge won't work
if(myEpoch < deadline) {
x.style.height="65px";
x.style.width="85px";
x.style.opacity="0.5";
} else {}
}
function defaultimg(x) {
x.style.height="60px";
x.style.width="80px";
x.style.opacity="1.0";
}
function teamback(x) {
var myDate = new Date(); // Your timezone!
var myEpoch = myDate.getTime()/1000;
var deadline = '1344700055.000';
//determines if user was on time..if not on time submitting won't work
if(myEpoch > deadline) {
// update the "actualone" image's source to the sending-image's source
document.getElementById("actualone").src = x.src;
document.getElementById("curtime").innerHTML = myEpoch;
document.getElementById("team").innerHTML = x.id;
document.getElementById("team").innerHTML = x.value;
} else {}
}
</script>

value是一个只能应用于表单元素的属性，如input。如果要获取简单属性，请使用 name 。
更改
document.getElementById("team").innerHTML = x.id;
document.getElementById("team").innerHTML = x.value;
自
document.getElementById("team").innerHTML = x.id;
document.getElementById("scenario").innerHTML = x.name;
您还可以使用 expando 属性，以便添加自定义属性（如"value"）并使用 JavaScript/jQuery 读取它。
