有tabs的项目里,进入子层级时,底部导航还一直存在,本人是要让他只在首页几个界面存在,其余的隐藏,在这里用到了angularjs的指令,要完成这个步骤分为三步:javascript
1.在标签ion-tabs中添加:ng-class=”{‘tabs-item-hide’: $root.hideTabs}”,源码以下:css
<ion-tabs class="tabs-icon-top" ng-class="{'tabs-item-hide': $root.hideTabs}"> //tabs </ion-tabs>
2.添加angularjs的指令,源码以下:java
//app已经在其余文件中指定,如var app = angular.module("starter",["ionic"]) angular.module('starter', ['ionic', 'starter.controllers', 'starter.services']) .directive('hideTabs', function ($rootScope,$location) { return { restrict: 'AE', link: function (scope, element, attributes) { scope.$on('$ionicView.beforeEnter', function () { scope.$watch(attributes.hideTabs, function (value) { $rootScope.hideTabs = value; if ($location.path() == '/main_tab/mian' || $location.path() == '/main_tab/mian') { //scope.$on('$ionicView.beforeLeave', function() { // $rootScope.hideTabs = false; //}); } }) }) } } })
//app已经在其余文件中指定,如var app = angular.module("starter",["ionic"]) app.directive('hideTabs', function($rootScope) { return { restrict: 'A', link: function(scope, element, attributes) { scope.$on('$ionicView.beforeEnter', function() { scope.$watch(attributes.hideTabs, function(value){ $rootScope.hideTabs = value; }); }); scope.$on('$ionicView.beforeLeave', function() { $rootScope.hideTabs = false; }); } }; });
3.三你想要隐藏的界面标签 ion-view添加表达式hide-tabs=”true”,源码以下:angularjs
//这是官网模板中的文件<ion-view hide-tabs="true" view-title="{{chat.name}}"> <ion-content class="padding"> <img ng-src="{{chat.face}}" style="width: 64px; height: 64px"> <p> {{chat.lastText}} </p> </ion-content></ion-view>
4.web
另外,若是要把效果搞得好看点,没有什么延迟现象,须要改动ionic.css文件,改动他须要用scss,这些内容前面也有介绍,改动地方以下:app
.tabs { -webkit-transition: all linear 0.2s; transition: all linear 0.2s; } .tabs-item-hide > .tabs{ -webkit-transition: all linear 0.2s; transition: all linear 0.2s; bottom: -$tabs-height; display: flex; }
上面内容在tabs.scss文件中!
