angular实现的按钮提示

用angularJS简单实现了一个小的按钮提示,html文件中需要引入jquery.js和angular.js

css代码:

<style type="text/css">        *{margin: 0px;padding: 0px;}        .bucSelectedButton{width: 100px;line-height: 30px;text-align: center;position: relative;}        .bucSelected {border:1px solid rgb(195,195,195);color:#000;cursor: pointer;border-radius: 6px;background-color: rgb(255,255,255);}        .bucSelectedHover{border: 1px solid rgb(74,201,255);color: rgb(74,201,255);cursor: pointer;border-radius: 6px;background-color: rgb(238,249,254);}        .bucSelectedHover .tip {color: rgb(0,0,0);background-color: rgb(255,255,255);}    </style>

html代码:

<div ng-controller="bucTipController">    <!-- 指令 -->    <buc-button id="numberType" my-title="按钮" tip-title = "这个是提示" style="margin-top:60px;"></buc-button></div>

js代码:

<script type="text/javascript">var app = angular.module("tip",[]);app.controller("bucTipController",function(){}).directive("bucButton",function(){    return {        restrict : ‘E‘,        replace : true,        scope : {            myTitle : "@",            id : "@",            tipTitle : "@"        },        template : "<button class=‘bucSelectedButton bucSelected‘ ng-click=‘clicked()‘ ng-mouseover = ‘mouseover()‘ ng-mouseout = ‘mouseout()‘>{{myTitle}}                <div style=‘border:1px solid #dcdcdc;border-radius:6px;width:auto;height:20px;line-height:20px;position:absolute;top:-40px;padding:5px;white-space:nowrap;background-color:#fafafa;display:none;color:#000;left:20px;‘ class=‘tip‘>{{tipTitle}}                    <span style=‘position:absolute;top:25px;left:10px;background-color:#fafafa;border:1px solid #dcdcdc;width:10px;height:10px;transform:rotate(45deg);border-left:none;border-top:none;‘>                    </span>                </div>                </button>",        link : function(scope,elem,attrs) {            scope.mouseover = function(){                $(".tip").show();            }            scope.mouseout = function(){                $(".tip").hide();            }            scope.clicked = function(){                elem.toggleClass("bucSelectedHover");                $(".tip").hide();            }        }    }})</script>

鼠标移入按钮,tip提示出现,鼠标移出的时候,tip消失。tip的小三角我是利用了css3的属性来实现的。
