Undefined function: .succes in $http.post (angular.js)
提问by Consolee Logg
I've been trying to make a search with Angular JS but I get this weird error: TypeError: undefined is not a function and it is on the .success
我一直在尝试使用 Angular JS 进行搜索，但我收到了这个奇怪的错误：TypeError: undefined is not a function and it is on the .success
Here is my code:
这是我的代码：
<html ng-app="app">
<head>
<meta charset="utf-8">
<script src="angular.js"></script>
<script>
var app = angular.module('app', []);
app.controller('ctrl', function ($scope, $http){
$scope.url = 'fetch.php';
$scope.search = '';
$scope.postLink = function(){
$http.post($scope.url, { "data" : $scope.search}).succes(function(data, status){
console.log(data);
}).error(function(data, status) {
$scope.data = data || "Request failed";
$scope.status = status;
});
}
});
</script>
</head>
<body ng-controller="ctrl">
<input type="text" ng-model="search">
<input type="submit" ng-click="postLink()">
</body>
</html>
Can anyone tell my why it gives me an error on the .succes? Am I not allowed to call it there?
谁能告诉我为什么它在 .succes 上给我一个错误？我不能在那里打电话吗？
Thanks in advance!
提前致谢！

It is spelled success.
它是拼写的success。
$httpis promised based, so you can also use:.thenfor success,.catchfor fail and.finallyin both cases.
$http是基于承诺的，所以你也可以使用：.then成功，.catch失败，.finally在这两种情况下。

There is a typo in the succesfunction name. Despite that, the successand errorfunctions are now removed as of Angular 1.6 and should be replaced with the standard promise functions .then()/ .catch().
succes函数名有错别字。尽管如此，success和error函数现在从 Angular 1.6 开始被移除，应该替换为标准的 promise 函数.then()/ .catch()。
More details in this answer: Why are angular $http success/error methods deprecated? Removed from v1.6?

It's thenfor $http promises.
它then用于 $http 承诺。
At second, you have a typo, it should be success
其次，你有一个错字，应该是 success
