动态网页在使用过程中，有时需要使用javascript来动态控制某个网页元素的一些事件，比如当用户做一些操作后需要禁止元素的onmouseover事件，而在做一些其他操作后又需要打开此事件时，就需要进行动态控制了，方法如下：
function
disableAllPriceButton(v){
obj = document.getElementById( " APB_1 " );
if ( ! v)
{
obj.onmouseover = function (){ this .className = 'pai_bidactionhover';};
obj.onmouseout = function (){ this .className = 'pai_bidaction';};
obj.detachEvent ( " onclick " ,addPrice);
obj.attachEvent( " onclick " ,addPrice);
obj.className = " pai_bidaction " ;
} else {
obj.onmouseover = function (){};
obj.onmouseout = function (){};
obj.detachEvent ( " onclick " ,addPrice);
obj.className = " pai_bidactionoff " ;
}
}
function addPrice(){
alert(event.srcElement.id);
}
obj = document.getElementById( " APB_1 " );
if ( ! v)
{
obj.onmouseover = function (){ this .className = 'pai_bidactionhover';};
obj.onmouseout = function (){ this .className = 'pai_bidaction';};
obj.detachEvent ( " onclick " ,addPrice);
obj.attachEvent( " onclick " ,addPrice);
obj.className = " pai_bidaction " ;
} else {
obj.onmouseover = function (){};
obj.onmouseout = function (){};
obj.detachEvent ( " onclick " ,addPrice);
obj.className = " pai_bidactionoff " ;
}
}
function addPrice(){
alert(event.srcElement.id);
}
