我正在尝试禁用此脚本中的表单操作。有人可以帮我禁用或删除表单“动作”变量吗?我正在使用脚本编写表单来上传图像,但是当我提交表单时,会调用在此脚本上设置的操作。
有人可以请教吗?
function $m(theVar){
return document.getElementById(theVar)
}
function remove(theVar){
var theParent = theVar.parentNode;
theParent.removeChild(theVar);
}
function addEvent(obj, evType, fn){
if(obj.addEventListener)
obj.addEventListener(evType, fn, true)
if(obj.attachEvent)
obj.attachEvent("on"+evType, fn)
}
function removeEvent(obj, type, fn){
if(obj.detachEvent){
obj.detachEvent('on'+type, fn);
}else{
obj.removeEventListener(type, fn, false);
}
}
