angularjs注入拦截器实现Loading效果
2014年12月19日 · 142 字 · 1 分钟
angularjs作为一个全ajax的框架,对于请求,如果页面上不做任何操作的话,在结果烦回来之前,页面是没有任何响应的,不像普通的HTTP请求,会有进度条之类。
本文通过对httpProvider注入拦截器实现loading。
HTML代码
<div class="loading-modal modal" ng-if="loading">
<div class="loading">
<img src="<?=$this->module->getAssetsUrl()?>/img/loading.gif" alt=""/><span ng-bind="loading_text"></span>
</div>
</div>
LESS代码
.modal {
position: fixed;
width: 100%;
height: 100%;
left: 0;
top: 0;
z-index: 99;
background: rgba(0, 0, 0, 0.3);
overflow: hidden;
}
.loading {
position: absolute;
top: 50%;
background: white;
#solution> .border-radius(8px);
width: 160px;
height: 72px;
left: 50%;
margin-top: -36px;
margin-left: -80px;
text-align: center;
img {
margin-top: 12px;
text-align: center;
}
span {
display: block;
}
}
JS代码
app.config(["$routeProvider", "$httpProvider", function ($routeProvider, $httpProvider) {
$routeProvider.when('/', {
templateUrl: "/views/reminder/index.html",
controller: "IndexController"
});
$routeProvider.when('/create', {
templateUrl: "/views/reminder/item/create.html",
controller: "ItemCreateController"
});
$routeProvider.otherwise({redirectTo: '/'});
$httpProvider.interceptors.push('timestampMarker');
}]);
//loading
app.factory('timestampMarker', ["$rootScope", function ($rootScope) {
var timestampMarker = {
request: function (config) {
$rootScope.loading = true;
config.requestTimestamp = new Date().getTime();
return config;
},
response: function (response) {
// $rootScope.loading = false;
response.config.responseTimestamp = new Date().getTime();
return response;
}
};
return timestampMarker;
}]);
