angular之modal实现

方法一：bootstrap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;
}
})
