//自定义指令
Vue.directive('drag',function(){
var oDiv = this.el;
oDiv.onmousedown = function(ev){
var disX = ev.clientX -oDiv.offsetLeft;
var disY = ev.clientY - oDiv.offsetTop;
document.onmousemove = function(ev){
var l = ev.clientX-disX;
var t = ev.clientY-disY;
oDiv.style.left = l+'px';
oDiv.style.top = t+'px';
};
document.onmouseup = function(){
document.onmousemove=null;
document.onmouseup=null;
};
};
});
window.onload = function(){
var vm = new Vue({
el:'#box',
data:{}
});
}
</script>
</head>
<body>
<div id="box">
