我的任务
分享jsp页面报“缺少对象”错误是怎么回事
我用的是struts1框架，要上传excel，现在页面中表单提交的时候根本进入不到后台，执行完js的onclick事件之后就提示缺少对象，我alert()的时候，不管alert哪里都先出alert，然后提示是否确定批量上传，点击确定之后就会提示缺少对象。这是怎么回事呢，这种错误我都应该从哪些方面去寻找错误点呢，下面是代码，求大神指点一下，谢谢哒

这是disableActions的定义
function disableActions() {
var form = document.forms[0];
for (var i = 0; i < form.elements.length; i++) {
var element = form.elements[i];
if ((element.type == "button") ||
(element.type == "submit") ||
(element.type == "reset")) {
element.disabled = true;
}
}
//for (var i=0;i<document.anchors[].length;i++){
// document.anchors[i].disabled = true;
//}
document.body.style.cursor = "wait";
}

disableActions调的是另外一个函数，引用了另外的js文件

这个是让下面action的路径不可用然后在配置文件里配置进行提交的，

disableActions();和document.fileUploadForm.action这两个有问题吧
disableActions();这个定义了吗？
fileUploadForm是什么？从哪里来的
