如何在使用组件路由角度浏览页面时保留值1.5
问题描述:
最近我实现了角度为1.5的组件路由。但是,我不能在浏览页面时保留值。 如何在浏览页面时保留值。看看这个PLUNKER。这是两个页面导航的非常基本的例子。如何在使用组件路由角度浏览页面时保留值1.5
当我在页面1上输入/选择值时,我移动到下一页。当我来到上一页所有值重置,它不是保留值。我们如何在浏览页面时实现保留值?这个例子只有两个页面导航,在真正的应用程序中,我将有5-10页的导航。
如果可以保留切换选择。那太好了。 这里是我的代码:
的JavaScript
(function(angular) {
'use strict';
var module = angular.module('app', ['ngComponentRouter']);
module.config(function($locationProvider) {
$locationProvider.html5Mode(true);
});
module.value('$routerRootComponent', 'myFirstApp');
module.component('myFirstApp', {
templateUrl: "mainview.html",
$routeConfig: [{
path: '/',
redirectTo: ['/First']
}, {
path: '/first',
name: 'First',
component: 'firstComponent'
}, {
path: '/second',
name: 'Second',
component: 'secondComponent'
}]
})
module.component('firstComponent', {
templateUrl: "1.html",
controllerAs: "vm",
controller: function($rootScope) {
$rootScope.title = "Title from Page 1";
var vm = this;
vm.clusters = {};
vm.$onInit = $onInit;
vm.selectNumericValue = selectNumericValue;
vm.selectAlphaValue = selectAlphaValue;
// default selection
function $onInit() {
vm.clusters.numericValue = '111';
vm.clusters.alphaValue = 'AAA';
}
// setting numeric value
function selectNumericValue(numValue) {
vm.clusters.numericValue = numValue;
if (vm.clusters.numericValue === '111') {
vm.clusters.numericValue = '111';
} else {
vm.clusters.numericValue = '222';
}
}
function selectAlphaValue(alphaValue) {
vm.clusters.alphaValue = alphaValue;
if (vm.clusters.alphaValue === 'AAA') {
vm.clusters.alphaValue = 'AAA';
} else if (vm.clusters.alphaValue === 'BBB') {
vm.clusters.alphaValue = 'BBB';
} else {
vm.clusters.alphaValue = 'CCC';
}
}
}
});
module.component('secondComponent', {
templateUrl: "2.html",
controller: function($rootScope) {
$rootScope.title = "Title from Page 2";
},
});
})(window.angular);

您可以使用共享服务这样的:
个module.service('sharedService', function() {
});
module.component('firstComponent', {
templateUrl: "1.html",
controllerAs: "vm",
controller: function($rootScope, sharedService) {
$rootScope.title = "Title from Page 1";
var vm = this;
vm.clusters = {};
vm.$onInit = $onInit;
vm.sharedService = sharedService;
vm.sharedService.selectNumericValue = selectNumericValue;
vm.sharedService.selectAlphaValue = selectAlphaValue;
...
});
<input type="textbox" ng-model="vm.sharedService.alphaValue" class="form-control">

您需要使用的服务或工厂在页面之间共享数据。 – jcubic
可以理解的是,如果可以通过保留任何价值来更新掠夺者。 – ankitd
