Vue.directive('drag',function(){
varoDiv=this.el;
oDiv.onmousedown=function(ev){
vardisX=ev.clientX-oDiv.offsetLeft;
vardisY=ev.clientY-oDiv.offsetTop;
document.onmousemove=function(ev){
varl=ev.clientX-disX;
vart=ev.clientY-disY;
oDiv.style.left=l+'px';
oDiv.style.top=t+'px';
};
document.onmouseup=function(){
document.onmousemove=null;
document.onmouseup=null;
