[英]Get id of the HTML element with AngularJS
我需要獲取每行的特定ID並轉發到發出HTTP請求的JS函數。 , the parameters are correct but the alert doesn't run. 但是我在調用此函數遇到麻煩,參數正確但警報沒有運行。
這是為什么?
的HTML
<!DOCTYPE html>
<html ng-app="oknok">
<head lang="pt-br">
<meta charset="UTF-8"/>
<title>OKNOK Admin</title>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.4.1/angular.min.js"></script>
<script src="js/controller.js"></script>
<link rel="stylesheet" href="http://maxcdn.bootstrapcdn.com/bootstrap/3.2.0/css/bootstrap.min.css">
</head>
<body ng-controller="indexController" data-ng-init="init()">
<div class="container">
<h2>Listagem de veículos</h2>
<table class="table table-condensed">
<thead>
<tr>
<th>Nome</th>
<th>Tipo</th>
</tr>
</thead>
<tbody>
<tr ng-repeat="x in resultado">
<td ng-model="nome">{{x.nome}}</td>
<td ng-model="tipo">{{x.tipo}}</td>
<td ng-model="lixeira"><span class="glyphicon glyphicon-trash" ng-click="excluir({{x._links.self.href}})"></span></td>
</tr>
</tbody>
</table>
<div align="right">
<button type="button" class="btn btn-primary" ng-click="adicionarNovo()">Adicionar novo</button>
</div>
</div>
</body>
</html>
Controller.js
var oknok = angular.module('oknok', []);
oknok.controller('indexController', function ($scope, $http) {
$scope.init = function () {
$http.get("/api/veiculos")
.then(function (data) {
var embedded = data.data._embedded;
$scope.resultado = embedded.veiculos;
}).catch(function (error) {
alert("Erro ao obter dados!\n" + error);
});
};
$scope.adicionarNovo = function () {
window.location.href = "/cadastro";
};
$scope.excluir = function (id) {
alert("clicou" + "\t" + id);
}
});
這些功能不需要{{}}
就像每個人在ng-click
上所說的那樣刪除它們。
像那樣 :
ng-click="excluir(x._links.self.href)"
嘗試注入“ $ window”。 這樣,您將確保window對象具有適當的角度生命周期:
var oknok = angular.module('oknok', []);
oknok.controller('indexController', function ($scope, $http, $window) {
$scope.init = function () {
$http.get("/api/veiculos")
.then(function (data) {
var embedded = data.data._embedded;
$scope.resultado = embedded.veiculos;
}).catch(function (error) {
$window.alert("Erro ao obter dados!\n" + error);
});
};
$scope.adicionarNovo = function () {
$window.location.href = "/cadastro";
};
$scope.excluir = function (id) {
$window.alert("clicou" + "\t" + id);
}
});
