我有以下简单的基于 CRUD 的代码(大部分来自 AwesomeTodo 教程)。这是一个 html 文件,只是一个网格,当调用 create() 时,我希望 UI 会更新。这个应用程序有效!当我创建新记录时它只是不刷新视图,我必须刷新显然重新加载资源的浏览器。
<div id="apps-table" compile="html">
<table ng-controller="AppCtrl" class="table table-striped table-bordered table-hover">
<thead>
<tr>
<th>Name</th>
<th>URL</th>
<th>Label</th>
<th>Description</th>
<th>Status</th>
<th>Location</th>
<th><a ng-click="promptForNew()"><li class="icon-plus"></li> New App</a></th>
</tr>
</thead>
<tbody>
<tr style="display:none" id="add-app-row">
<td><input class="input-small" type="text" ng-change = "formChanged()" ng-model="app.fields.name"></td>
<td><input class="input-small" type="text" ng-change = "formChanged()" ng-model="app.fields.url"></td>
<td><input class="input-small" type="text" ng-change = "formChanged()" ng-model="app.fields.label"></td>
<td><input class="input-small" type="text" ng-change = "formChanged()" ng-model="app.fields.description"></td>
<td><select ng-model="app.fields.is_active" ng-change = "formChanged()">
<option value=1>Active</option>
<option value=0>Inactive</option>
</select>
</td>
<td><select ng-model="app.fields.is_url_external" ng-change = "formChanged()">
<option value=0>Internal</option>
<option value=1>External</option>
</select></td>
<td>
<a ng-click="create()" id="save_new" class="btn btn-small btn-primary disabled" href=""><i class="icon-save"></i></a>
</td>
</tr>
<tr ng-repeat="app in Apps.record" id="row_{{app.fields.id}}">

var AdminApp = angular.module("AdminApp", ["ngResource"]).
config(function($routeProvider) {
$routeProvider.
when('/', { controller: AppCtrl, templateUrl: 'applications.html' }).
otherwise({ redirectTo: '/' });
});
AdminApp.factory('App', function($resource) {
return $resource('/rest/system/app/:id/?app_name=admin', {}, { update: { method: 'PUT'}});});
var AppCtrl = function ($scope, App) {
$scope.Apps = App.get();
$scope.formChanged = function(){
$('#save_' + this.app.fields.id).removeClass('disabled');
};
$scope.promptForNew = function(){
$('#add-app-row').show();
};
$scope.save = function () {
var records = {};
var record = {};
record.fields = this.app.fields;
delete record.fields.name;
records.record = record;
var id = this.app.fields.id;
App.update({id:id}, records, function () {
$('#save_' + id).addClass('disabled');
});
};
$scope.create = function() {
var currentScope = $scope;
var records = {};
var record = {};
record.fields = this.app.fields;
records.record = record;
App.save(records, function() {
$('#add-app-row').hide();
});
};
$scope.delete = function () {
var id = this.app.fields.id;
App.delete({ id: id }, function () {
$("#row_" + id).fadeOut();
});
};
};
这是 index.html:
<!DOCTYPE html>
<html ng-app="AdminApp">

<meta http-equiv="content-type" content="text/html; charset=utf-8"/>
<meta name="viewport" content="width=device-width, initial-scale=1, maximum-scale=1.0, user-scalable=no">

<div class="container">

我所有的操作都是通过 ng-click,所以我似乎没有在“Angular 之外”做任何事情
问题是,这段代码是否正常工作?还是应该真正更新?
我可以更新范围的唯一方法是手动使用:
$scope.Apps.record.push($scope.app);
那太可怕了。不能使用 apply 或 digest,我也不应该这样做。
