AngularJS implements button prompts and click color effects, and angularjs changes color

This article uses angularJS to easily implement a small button prompt, which will change color after the button is clicked. Note that jquery. js and angular. js need to be introduced in the html file.

Run:

When you click the button, the style of the button changes:

Css code:

<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 code:

<Div ng-controller = "bucTipController"> <! -- Command --> <buc-button id = "numberType" my-title = "button" tip-title = "this is the prompt" style = "margin-top: 60px; "> </buc-button> </div>

Js Code:

<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>

When you move the cursor to the button, the tip prompt appears. When you move the cursor out, the tip disappears. The small triangle of tip is implemented using the attributes of css3.
