下面给大家分享vue自定义指令拖拽功能代码，具体代码如下所示：
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>实例方法</title>
<meta name="viewport" content="width=device-width, initial-scale=1.0, maximum-scale=1.0, user-scalable=0">
<meta name="apple-mobile-web-app-capable" content="yes">
<meta name="apple-mobile-web-app-status-bar-style" content="black">
<script src="../js/vue1.0.js"></script>
<script src="../js/vue-resource.js"></script>
<script>
//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">
<div v-drag :style="{width:'100px', height:'100px', background:'aqua', position:'absolute', right:0, top:0}">
</div>
</div>
</body>
</html>

<script src="../js/vue-resource.js"></script>
<script>
Vue.directive('on').keyCodes.ctrl=17;
Vue.directive('on').keyCodes.myenter=13;
window.onload = function(){
var vm = new Vue({
el:'#box',
data:{},
methods:{
show:function(){
alert(111);
}
}
});
}
</script>
</head>
<body>
<div id="box">
