当点击按钮的时候 按钮的样式改变:
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。
