1.bootstrp的弹出提示
bootstrap已经帮我们封装了非常好用的弹出提示Popover。

2.自定义popover指令
我们使用一个指令给任意元素加上popover，并且可以根据情况改变popover的content内容。
JS：
代码语言：javascript复制<script>
var app = angular.module('testApp', []);
app.factory('dataService',function() {
var service = {};
service.cacheObj = {};
service.getAppName = function (appId, callback) {
if (service.cacheObj[appId]) {
console.log('get name from cache');
callback(service.cacheObj[appId]);
return;
}
//here is sample. Always ajax.
service.cacheObj[appId] = 'QQ';
callback('QQ');
};
return service;
});
app.directive('myPopover', function (dataService) {
return {
restrict: 'AE',
link: function (scope, ele, attrs) {
$(ele).data('title','App');
$(ele).data('content', "<div id ='popDiv'>Name:-</div>");
$(ele).popover({ html: true, trigger: 'hover'});
$(ele).on('shown.bs.popover',function() {
var popDiv = $('#popDiv');
console.log(popDiv);
dataService.getAppName('xxx',function(name) {
popDiv.html('Name:' name);
});
});
}
};
});
app.controller("test",function($scope) {
});
</script>html：
代码语言：txt复制<div ng-app="testApp">
<div ng-controller="test">
<div>
<a my-popover>app 1</a>
<a my-popover>app 2</a>
</div>
</div>
</div>
