为什么我的NG-模型变量在控制器未定义? [英] Why is my ng-model variable undefined in controller?
问题描述
我有我的角度JS项目,$范围的麻烦。当我使用NG-模式=modelExample在输入栏上例如,我不能用$ scope.modelExample我的js访问它。任何人都有类似的问题?
这是奇怪的,一个函数被调用,但NG-模型不绑定。看到我的code以下,功能refreshResults()是当我提交表单调用,但$ scope.search返回未定义。
angular.module('启动',
['离子',
starter.controllers',
starter.filters',
akoenig.deckgrid',
angucomplete
//'ui.bootstrap',
'starter.services'])的.config(函数($ stateProvider,$ urlRouterProvider){
$ stateProvider
.STATE('应用',{
网址:/应用程序
摘要:真实,
templateUrl:模板/ menu.html
控制器:'AppCtrl
}) .STATE('app.browse',{
网址:/浏览,
观点:{
menuContent:{
templateUrl:模板/ browse.html
控制器:'BrowseCtrl
}
}
}) .STATE('app.search',{
网址:/搜索,
观点:{
menuContent:{
templateUrl:模板/ search.html
控制器:'SearchCtrl
}
}
})
//如果没有上述状态相匹配,以此作为后备
$ urlRouterProvider.otherwise('/应用/浏览');
});
angular.module('starter.controllers',[])
.controller('SearchCtrl',函数($范围){
$ scope.refreshResults =功能(){
的console.log($ scope.search);
};
})

@DavidTryon解决了我的问题的意见。我使用的范围是错误的。我需要使用一个对象而不是字符串。换句话说,我需要做的是这样 NG-模式=search.term
不是 NG-模式=搜索
并在JS像这样使用它: $ scope.search.term
。它做继承,但长话短说,如果你的NG-模型没有一个点在里面(。),你这样做是错误的。

I'm having trouble with $scope in my angular js project. When I use ng-model="modelExample" on an input field for example, I can't access it in my js using $scope.modelExample. Has anyone else had a similar problem?
It's bizarre, a function is called but ng-model doesn't bind. See my code below, the function refreshResults() is called when I submit the form but $scope.search returns as undefined.
angular.module('starter',
['ionic',
'starter.controllers',
'starter.filters',
'akoenig.deckgrid',
"angucomplete",
// 'ui.bootstrap',
'starter.services'])
.config(function($stateProvider, $urlRouterProvider) {
$stateProvider
.state('app', {
url: "/app",
abstract: true,
templateUrl: "templates/menu.html",
controller: 'AppCtrl'
})
.state('app.browse', {
url: "/browse",
views: {
'menuContent' :{
templateUrl: "templates/browse.html",
controller: 'BrowseCtrl'
}
}
})
.state('app.search', {
url: "/search",
views: {
'menuContent' :{
templateUrl: "templates/search.html",
controller: 'SearchCtrl'
}
}
})
// if none of the above states are matched, use this as the fallback
$urlRouterProvider.otherwise('/app/browse');
});
angular.module('starter.controllers', [])
.controller('SearchCtrl', function($scope) {
$scope.refreshResults = function() {
console.log($scope.search);
};
})
<ion-view>
<ion-content class="has-header">
<form ng-submit="refreshResults()" class="bar bar-header item-input-inset">
<label class="item-input-wrapper">
<i class="icon ion-ios7-search placeholder-icon"></i>
<input type="search" placeholder="Search..." ng-model="search">
</label>
</form>
</ion-content>
</ion-view>
@DavidTryon solved my issue in the comments. I was using scope wrong. I needed to use an object not a string. In other words I need to do something like ng-model="search.term"
not ng-model="search"
and use it in the js like this: $scope.search.term
. It has to do with inheritance but long story short, if your ng-model doesn't have a dot (.) in it, you're doing it wrong.

Thanks David!
