 <div class="wei" wei-yi data="true"></div>
 <div class="wei" wei-yi data="false"></div>
 <script src="jquery.js" type="text/javascript" charset="utf-8"></script>
 <script src="angular.min.js" type="text/javascript" charset="utf-8"></script>
 <script type="text/javascript">
 var app = angular.module('myApp',[]);
 //自定义属性
 app.directive("weiYi",function(){
 return{
 restrict :'A',//A属性,E标签,C类名,D注释
 link :function(scope,element,attr){
 attr.data=angular.equals(attr.data,"true");
 //console.log(attr.data);
 console.log(element);
 element.on("mousedown",function(e){
 var that = $(this);
 console.log(attr.data);
 if(attr.data){
 $div=$("<div>");
 console.log($div);
 $div.css({"width":"100px","height":"100px","border": "2px dotted green","position":"absolute","left":that.offset().left,"top":that.offset().top});
 $div.appendTo($("body"));
 }
 var x=e.clientX-$(this).offset().left;
 var y=e.clientY-$(this).offset().top;
 //console.log(x+":"+y);
 $(document).on("mousemove",function(e){
 if(attr.data){
 $div.css({"left":e.clientX-x,"top":e.clientY-y});
 }else{
 that.css({"left":e.clientX-x,"top":e.clientY-y});
 }
 });
 $(document).on("mouseup",function(e){
 //console.log($div);
 $(document).off();
 if(attr.data){
 that.css({"left":$div.offset().left,"top":$div.offset().top});
 $div.remove();
 }
 })
 })
 }
 }
 });
 app.controller('show',['$scope',function(scope$){
 }]);
 </script>
 </body>
</html>
