方法一：bootstrap实现

对于bootstrap的实现，感觉功能比较多，比较复杂，不建议实现。

方法二：自己阉割实现

angular.module('myModal',[]).provider('Modal',function($injector){this.$get = function($document.$compile,$http,$templateCache,$rootScope,$controller,$q){var Modal = function(){_.bindAll(this,'close','dismiss','stop');this.defer = $q.defer();this.result = this.defer.promise;        }Modal.openedItems = 0;Modal.open = function(options){Modal.openedItems++;var modal = new Modal();var templatePromise = $http.get(options.templateUrl,{cache:$templateCache});var resolvePromise = function(){var promiseArr = [];angular.forEach(options.resolve || {},function(value,key){if(angular.isFunction(value) || angular.isArray(value)){promiseArr.push($q.when($injector.invoke(value)));}})return promiseArr;}}var promises = $q.all([templatePromise].concat(resolvePromise()));promises.then(function(tplAndVars){var body = $document.find('body').eq(0);var element = angular.elemet('<div class="cover-wrap"></div>' + tplAndVars[0].data);var modalScope = (options.scope || $rootScope).$new();modalScope.$close = modal.close;modalScope.$dismiss = modal.dismiss;modalScope.$stop = modal.stop;var ctrlLocals = {};var resolveIter = 1;angular.forEach(options.resolve,function(value,key){ctrlLocals[key] = tplAndVars[resolveIter++];});ctrlLocals.$scope = modalScope;ctrlLocals.$modal = modal;$controller(options.controller,ctrlLocals);var angularElement = $compile(element)(modalScope);body.append(angularElement);modal.element = angularElement;modal.$scope = modalScope;});return modal;}
})
