AngularJS实现按钮提示与点击变色效果

本文用angularJS简单实现了一个小的按钮提示,按钮点击后会变色,注意html文件中需要引入jquery.js和angular.js

运行截图:

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。

总结
