请问：
怎么无法触发onCick事件。
//window.onload = function() { //去掉
function insertRow(){
alert("ok");
var rowIndex1 = document.all("addordel").length;
if(rowIndex1 >= 5){
alert('一次最多能上传5个文件');
return false;
}
var obj=document.getElementsByName("addordel")[0].cloneNode(true);
document.all("change").appendChild(obj);
}
function delRow(){
alert("fff");
var rowIndex = document.all("addordel").length;
if(rowIndex >= 2){
event.srcElement.parentNode.removeNode(true);
}
}
function chkfile(){
alert("okok");
obj = document.getElementsByName('upname[]');
num = obj.length;
for(i=0;i<num;i++){
if(obj[i].value == 0){
alert('请添加上传文件');
return false;
}
}
}
//}//去掉
你可以改为
把type改为button
然后点击事件中用ajax方式提交表单
2：要么，在window.onload = function() {
//在这里直接绑定事件,比如你最后的上传事件绑定
document.getElementById("upbtn").onclick=chkfile;
}
