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>

下面看下Vue自定义键盘信息

<!DOCTYPE html><html lang="en"><head>  <meta charset="UTF-8">  <title>自定义键盘信息</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>    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">  <input type="text" @keydown.ctrl="show">  <hr>  <input type="text" @keydown.myenter="show | debounce 2000"></div></body></html>
