我正在尝试将下拉列表中选定的项目传递给 Controller 中的函数。
但是，我发现它是未定义的。
HTML:
<!DOCTYPE html>
<html>
<head>
<script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/angularjs/1.3.9/angular.min.js"></script>
<link rel="stylesheet" href="style.css">
<script src="script.js"></script>
</head>
<body>
<h1>Hello Plunker!</h1>
<div ng-app="MyApp" ng-controller="MyController">
<select ng-model="ddlFruits"
ng-options="fruit.Id as fruit.Name for fruit in Fruits track by fruit.Id"
ng-change="GetValue(fruit)">
</select>
</div>
</body>
</html>
脚本:
var app = angular.module('MyApp', [])
app.controller('MyController', function ($scope, $window) {
$scope.Fruits = [{
Id: 1,
Name: 'Apple'
}, {
Id: 2,
Name: 'Mango'
}, {
Id: 3,
Name: 'Orange'
}];
$scope.GetValue = function (fruit) {
alert(fruit);
}
});
最佳答案
嗨，HTML 更改此内容
ng-change="GetValue(ddlFruits)"
从控制台您将获得所选的 ID
<select ng-model="ddlFruits"
ng-options="fruit.Id as fruit.Name for fruit in Fruits track by fruit.Id"
ng-change="GetValue(ddlFruits)">
</select>
