我对Angular很新,所以如果我在这里遗漏了一些非常基本的东西,我很抱歉 - 这只是因为我已经搜索了一半的互联网,但我可以&似乎找到一个例子或解释来帮助我。
我有一个带有数据的JSON文件(news.json,本例存储在本例中):
[
{
"id": 1,
"title": "Het allereerste nieuwsbericht",
"body": "WE LOVE ANGULAR!!",
"algemeen": true,
"leerlingen": true,
"personeel": true,
"ouders": true,
"day": "27",
"month": "05"
},
{
"id": 2,
"title": "Het allertweede nieuwsbericht",
(...)
应将新条目提交到JSON文件的表单的HTML模板:
<form ng-submit="submit()">
<label>Titel: </label>
<input type="text" ng-model="title" required /><br /><br />
<label>Tekst:<br /></label>
<textarea ng-model="body" required></textarea><br /><br />
<fieldset>
<legend>Voor wie is dit nieuwsbericht bestemd?</legend>
<input type="checkbox" ng-model="at_alg" value="Homepagina"> Homepagina<br />
<input type="checkbox" ng-model="at_lln" value="Leerlingen"> Leerlingen<br />
<input type="checkbox" ng-model="at_per" value="Personeel"> Personeel<br />
<input type="checkbox" ng-model="at_oud" value="Ouders"> Ouders
</fieldset><br /><br />
<button type="submit"> Sla het artikel op </button>
指令本身:
app.directive('postNews', function($http){
return {
restrict: 'E',
scope: {},
templateUrl: 'pages/postnews.html',
link: function(scope, element, attrs) {
$scope.submit = function() {
var toSend = {
title: $scope.title,
body: $scope.body,
}
$http.post('data/news.json', toSend)
.success(function(data, status, headers){
alert('Het bericht is toegevoegd.');
$scope.title = '';
$scope.body = '';
})
.error(function(data, status, headers){
alert('Oeps... er is iets fout gegaan. Probeer het later opnieuw.');
});
};
}
};
});
这根本不做任何事情。我究竟做错了什么?提前谢谢!
