使用AngularJS,我正在创建一个用两个Web请求提取数据的表。
每个网络请求都在HTML ng-repeat="user in users"
和ng-repeat="app in apps"
中拥有自己的ng-repeat。现在,所有现有应用都会在user
的每次重复中显示。我想做的是某种匹配,查找或过滤,只显示与用户相关联的应用。所以,当user.Title == app.Title
。
这是HTML:
<div ng-app="myApp">
<div ng-controller="MainCtrl">
<div class="ProfileSheet" ng-repeat="user in users">
<h3 class="heading">User Profile</h3>
<table id="Profile">
<tr>
<th>User</th>
<td>{{user.Title}}</td>
</tr>
<tr>
<th>First Name</th>
<td>{{user.FirstName}}</td>
</tr>
<tr>
<th>Last Name</th>
<td>{{user.LastName}}</td>
</tr>
<tr>
<th>Job Title</th>
<td>{{user.JobTitle}}</td>
</tr>
<tr>
<th>Emp ID</th>
<td>{{user.EmployeeID}}</td>
</tr>
<tr>
<th>Officer Code</th>
<td>{{user.OfficerCode}}</td>
</tr>
<tr>
<th>Email</th>
<td>{{user.Email}}</td>
</tr>
<tr>
<th>Telephone</th>
<td>{{user.WorkPhone}}</td>
</tr>
<tr>
<th>Fax Number</th>
<td>{{user.WorkFax}}</td>
</tr>
<tr>
<th>Location Description</th>
<td>{{user.LocationDescription}}</td>
</tr>
<tr>
<th>Mailstop / Banking Center #</th>
<td>{{user.Mailstop}}</td>
</tr>
</table>
<br>
<h3 class="heading">User Applications</h3>
<div style="border:3px solid #707070; padding-right:12px;">
<h4 style="padding-left:5px;">User Applications</h4>
<table id="Apps">
<tr id="AppsHeading">
<th>Application</th>
<th>User ID</th>
<th>Initial Password</th>
<th>Options / Comment</th>
<th>Setup Status</th>
</tr>
<tr ng-repeat="app in apps">
<td>{{app.Application.Title}}</td>
<td>{{app.Title}}</td>
<td>{{app.InitialPassword}}</td>
<td>{{app.OptionsComments}}</td>
<td style="border-right:3px solid #707070;">{{app.SetupStatus}}</td>
</tr>
</table>
</div>
</div>
</div>
JS:
var app = angular.module('myApp', ['ngSanitize']);
var basePath = "https://portal.oldnational.com/corporate/projecthub/anchormn/associates"
app.controller('MainCtrl', function($scope, $http, $q){
var supportList;
$(document).ready(function() {
$scope.getAdminList();
$scope.getAppsList();
});
// $scope.selectedIdx = -1;
// $scope.showResults = false
$scope.prepContext = function(url,listname,query){
var path = url + "/_api/web/lists/getbytitle('" + listname + "')/items" + query;
console.log(path);
return path;
}
$scope.getAdminList = function() {
supportList = $http({
method: 'GET',
url: this.prepContext(siteOrigin+"/corporate/projecthub/anchormn/associates","User Administration","?$orderBy=LastName"),
headers: {
"Accept": "application/json; odata=verbose"
}
}).then(function(data) {
//$("#articleSection").fadeIn(2000);
console.log("adminlist", data.data.d.results);
$scope.users = data.data.d.results;
});
};
$scope.getAppsList = function() {
supportList = $http({
method: 'GET',
// url: this.prepContext(siteOrigin+"/corporate/projecthub/anchormn/associates","User Applications","?$select=Title,InitialPassword,OptionsComments,SetupStatus,Application/Title&$orderBy=Application&$expand=Application"),
url: this.prepContext(siteOrigin+"/corporate/projecthub/anchormn/associates","User Applications","?$select=Title,InitialPassword,OptionsComments,SetupStatus,Application/Title,ParentUserLink/ID&$orderBy=Application&$expand=Application,ParentUserLink"),
headers: {
"Accept": "application/json; odata=verbose"
}
}).then(function(data) {
//$("#articleSection").fadeIn(2000);
console.log("appslist", data.data.d.results);
$scope.apps = data.data.d.results;
});
};
});
app.config([
'$compileProvider',
function($compileProvider){
$compileProvider.aHrefSanitizationWhitelist(/^\s*(https?|ftp|mailto|chrom-extension|javascript):/)
}
]);
我该怎么做?
答案 0 :(得分:1)
控制器中有很多无关的代码。出于这个答案的目的,我删除了它。此外,我了解用户和应用程序与名为Title
的属性相关,但名称让我感到困惑 - 如果数据没有意义,请原谅我。
建议:仅在必要时使用$
(jQuery)。 Angular提供了许多替代jQuery功能的功能。而不是像$.ready
那样使用:
$(document).ready(function() {
$scope.getAdminList();
$scope.getAppsList();
});
等待使用以下代码启动应用程序直到文档准备就绪:
(function () {
angular.element(document).ready(function () {
angular.bootstrap(document, ['myApp']);
});
})();
然后您不必为控制器负担,而是负责等待文档加载。 注意:ng-app
已从标记中删除。
建议:使用$q.all()
等待多个承诺解决。 $q.all()
会等到所有承诺决定致电.then()
。这有助于确保在您开始使用它时所有数据都可用。
建议:如果视图将使用属性和功能,则仅将其分配给$scope
。我删除了$scope
对象中视图未使用的函数。
当控制器加载时,我们使用$q.all()
来调用并等待fetchAdminList()
和fetchAppsList()
从API获取数据。每个API请求解析后,我们将.then()
回调中的数据打开并返回(有关promise链接的更多信息,以了解从.then()
返回值时会发生什么)。当两个promise都解决后,我们将数据存储在$scope
上,以使其可供视图使用。我们还预先计算每个用户可以使用的应用程序,并将这些数据存储在$scope.userApps
中,以使其可供视图使用。
我无法访问您从中获取数据的API。我使用$http
和静态数据立即解决了$q.resolve()
次调用。准备就绪后,只需将$q.resolve(...)
替换为获取功能中的原始$http(...)
来电。
运行代码段以查看其实际效果。

angular.element(document).ready(function () {
angular.bootstrap(document, ['myApp']);
