我刚刚开始学习Angular.js。如何在Angular.js中重写以下代码?
var postData = "<RequestInfo> "
+ "<Event>GetPersons</Event> "
+ "</RequestInfo>";
var req = new XMLHttpRequest();
req.onreadystatechange = function () {
if (req.readyState == 4 || req.readyState == "complete") {
if (req.status == 200) {
console.log(req.responseText);
}
}
};
try {
req.open('POST', 'http://samedomain.com/GetPersons', false);
req.send(postData);
}
catch (e) {
console.log(e);
}
这是我目前所掌握的-
function TestController($scope) {
$scope.persons = $http({
url: 'http://samedomain.com/GetPersons',
method: "POST",
data: postData,
headers: {'Content-Type': 'application/x-www-form-urlencoded'}
}).success(function (data, status, headers, config) {
$scope.data = data; // how do pass this to $scope.persons?
}).error(function (data, status, headers, config) {
$scope.status = status;
});
}
html
<div ng-controller="TestController">
<li ng-repeat="person in persons">{{person.name}}</li>
</div>
我的方向对吗?

在当前函数中,如果您将$scope.persons
赋值给$http
,这是一个promise对象,因为$http
返回一个promise对象。
因此,不是将scope.persons
赋值给$http,而是应该在$http
的成功内部赋值$scope.persons
,如下所述:
function TestController($scope, $http) {
$http({
url: 'http://samedomain.com/GetPersons',
method: "POST",
data: postData,
headers: {'Content-Type': 'application/x-www-form-urlencoded'}
}).success(function (data, status, headers, config) {
$scope.persons = data; // assign $scope.persons here as promise is resolved here
}).error(function (data, status, headers, config) {
$scope.status = status;
});
}
