要理解loading的原理，即在文档加载完成之前显示loading效果，隐藏主文档内容，而在文档加载完成之后，隐藏loading效果，显示主文档内容。

<!DOCTYPE html>
<html lang="zh_CN">

<script src="lib/ionic/js/jquery-2.1.3.min.js"></script>
<!-- ionic/angularjs js -->
<script src="lib/ionic/js/ionic.bundle.js"></script>
</head>
<body ng-app="myApp">

<!--设定预加载效果-->
<div class="spinner">
<div class="dot1"></div>
<div class="dot2"></div>
</div>

<ion-content class="page-one" ng-controller="FirstController">

<div class="row">
<div class="col">
<img src="img/header1.png">
</div>
</div>

</ion-content>

</body>
<script>
$(document).ready(function(){
$(".spinner").hide();
$(".page-one").show();
});
</script>
</html>

CSS关键代码：

/*loading效果*/
.spinner {
margin: 25% auto;
width: 90px;
height: 90px;
position: relative;
text-align: center;

-webkit-animation: rotate 2.0s infinite linear;
animation: rotate 2.0s infinite linear;
}

.dot1, .dot2 {
width: 60%;
height: 60%;
display: inline-block;
position: absolute;
top: 0;
background-color: #2d7cea;
border-radius: 100%;
-webkit-animation: bounce 2.0s infinite ease-in-out;
animation: bounce 2.0s infinite ease-in-out;
}

.dot2 {
top: auto;
bottom: 0px;
-webkit-animation-delay: -1.0s;
animation-delay: -1.0s;
}

@-webkit-keyframes rotate { 100% { -webkit-transform: rotate(360deg) }}
@keyframes rotate { 100% { transform: rotate(360deg); -webkit-transform: rotate(360deg) }}

@-webkit-keyframes bounce {
0%, 100% { -webkit-transform: scale(0.0) }
50% { -webkit-transform: scale(1.0) }
}

@keyframes bounce {
0%, 100% {
transform: scale(0.0);
-webkit-transform: scale(0.0);
} 50% {
transform: scale(1.0);
-webkit-transform: scale(1.0);
}
}
.page-one{
display: none;
}
