jquery实现BootStrap的弹出框拖动，及鼠标滚轮改变BootStrap的弹出框大小详解编程语言

鼠标滚轮改变BootStrap的弹出框大小

加了滚动监听事件，每次改变弹出框大小

 
var scrollFunc=function(e){ 
    e=e || window.event; 
   
    var ss=document.getElementById("test"); 
    if(ss.style.height==""){//改高度 
        ss.style.height=400+Number(e.wheelDelta)/10+"px"; 
    }else{ 
        ss.style.height=Number(ss.style.height.substr(0,ss.style.height.indexOf('px')))+Number(e.wheelDelta)/10+"px"; 
    } 
   
    if(ss.style.width==""){//改宽度 
        ss.style.width=900+Number(e.wheelDelta)/10+"px";//初始值 
    }else{ 
        ss.style.width=Number(ss.style.width.substr(0,ss.style.width.indexOf('px')))+Number(e.wheelDelta)/10+"px"; 
    } 
} 
/*注册事件*/ 
if(document.addEventListener){ 
    document.addEventListener('DOMMouseScroll',scrollFunc,false); 
}//W3C 
window.onmousewheel=document.onmousewheel=scrollFunc;//IE/Opera/Chrome
