Question

我不确定你是否可以这样做，但如果没有，请尽可能简单地为我提供一些工作。我希望用户选择一个img（id为'牛仔'或'巨人'）。我想得到这些（它们都是'One'）的价值并将其返回到id'场景'中。除了这部分之外，其他所有工作都有效，我觉得这是你无法做到的。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>

Answer 1

value是一个只能应用于表单元素的属性，例如input。如果您想获得一个简单的属性，请使用name。

Answer 2

更改

document.getElementById("team").innerHTML = x.id;
document.getElementById("team").innerHTML = x.value;

到

document.getElementById("team").innerHTML = x.id;
document.getElementById("scenario").innerHTML = x.name;

Answer 3

您还可以使用expando属性，这样您就可以添加自定义属性，例如'value'，并使用JavaScript / jQuery读取它。
