本文实例讲述了AngularJS实现的简单拖拽功能。分享给大家供大家参考，具体如下：
<!DOCTYPE html>
<html ng-app="myApp">
<head>
<meta charset="UTF-8">
<title>www.jb51.net AngularJS拖拽</title>
<style>
*{
padding:0;
margin:0;
}
.wei{
width:100px;
height:100px;
background: red;
position:absolute;
cursor: pointer;
/*left:0;top:0;*/
}
</style>
</head>
<body ng-controller="show">
<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>
运行效果如下：
