AngularJS记住视图之间的DOM状态

似乎Angular在路线改变时重新渲染整个视图。请参阅此示例:http://jsfiddle.net/RSHG8/1/

HTML:

<div class="nav">
    <a href="#/one">One</a><a href="#/two">Two</a>
</div>
<div ng-app="app" id="ng-app">
    <div ng-view=ng-view></div>
</div>

var app = angular.module('app', []);

JS:

app.config(function ($routeProvider) {
    $routeProvider.when('/one', {
        template: 'Template {{template}}<br>Enter some text: <input type="text" /> then click "Two"',
        controller: 'one'
    })
        .when('/two', {
        template: 'Template {{template}}<br>Click back to view "One" to see changes undone',
        controller: 'two'
    })
        .otherwise({
        redirectTo: '/one'
    });
});

app.controller("one", function ($scope) {
    $scope.template = "One";
});

app.controller("two", function ($scope) {
    $scope.template = "Two";
});

在视图之间切换时,忘记了用户输入的文本。对于非角度的东西,这也是一个问题。例如。一个jQuery expand-collapse插件。如果用户展开一定数量的元素,离开视图并返回,则状态将重置为折叠的所有内容。

是否可以将Angular设置为简单的显示/隐藏视图,而不是在路线更改时擦除重新渲染?

您可以尝试将ng-model分配给输入标记,并将值存储在父控制器中。

HTML

<div class="nav">
    <a href="#/one">One</a><a href="#/two">Two</a>
</div>
<div ng-app="app" id="ng-app">
    <div controller="AppCtrl">
        <div ng-view=ng-view></div>
    </div>
</div>

var app = angular.module('app', []);

JS

app.config(function ($routeProvider) {
        $routeProvider.when('/one', {
            template: 'Template {{template}}<br>Enter some text: <input type="text" ng-model="$parent.inputValue" /> then click "Two"',
            controller: 'one'
        })
            .when('/two', {
            template: 'Template {{template}}<br>Click back to view "One" to see changes undone',
            controller: 'two'
        })
            .otherwise({
            redirectTo: '/one'
        });
    });

    app.controller("AppCtrl", function AppCtrl($scope) {
        $scope.inputValue = "";
    });

    app.controller("one", function ($scope) {
        $scope.template = "One";
    });

    app.controller("two", function ($scope) {
        $scope.template = "Two";
    });
