Ionic基础——js指令布局

来源：互联网发布：吴昕淘宝店铺编辑：程序博客网时间：2024/04/29 15:35

1)页眉/ion-header-bar:标题栏

align-title——设置标题文字的对齐方式；

no-tap-scroll——当点击标题时，是否将内容区域自动滚动到初始位置；

2)页脚/ion-footer-bar：页脚栏

3)内容/ion-content:内容区

overflow-scroll——设置是否不用系统内置的滚动条；

scroll——设置内容是否禁止滚动(常用作百度地图等)；

<!DOCTYPE html><html ng-app="myApp"><head><meta name="viewport" content="initial-scale=1,maximum-scale=1,user-scalable=no,width=device-width,height=device-height"><script src="../lib/js/ionic.bundle.min.js"></script>    <link rel="stylesheet" type="text/css" href="../lib/css/ionic.min.css"></head><body ng-controller="firstCtrl"><ion-header-bar align-title="center" class="bar-positive" no-tap-scroll="false"><h1 class="title">ion-header-bar</h1></ion-header-bar><ion-content overflow-scroll="false"><ul class="list"><li class="item" ng-repeat="item in items">{{item}}</li></ul></ion-content>    <ion-footer-bar class="dark-bg">        <h1 class="title light">ion-footer-bar</h1>    </ion-footer-bar></body><script>angular.module("myApp",["ionic"]).controller("firstCtrl",function($scope){$scope.items = [];for(var i=0;i<20;i++)$scope.items.push("line " + i);});</script></html>

效果：

4)滚动框/ion-scroll

direction——设置内容可以滚动的方向；

zooming——是否支持pinch-to-zoom(捏拉缩放)；

<ion-scroll class="has-header" zooming="true" direction="xy" style="width: 500px; height: 500px"><div style="width: 5000px; height: 5000px; background: url('img/map.jpg') repeat"></div></ion-scroll>

5)下拉更新数据/ion-refresher

on-refesh——当用户向下拉动足够的距离并松开时，执行此表达式；

on-pulling——当用户开始向下拉动时，执行此表达式；

pulling-text——当用户向下拉动时，显示此文本；

pulling-icon——当用户向下拉动时，显示此图标；

refreshing-icon——当用户向下拉动并松开后，显示的等待图标。

spinner——作用与refreshing-icon一样，但spinner是基于svg动画(ionic推荐使用spinner)；

disable-pulling-rotation——禁止下拉图标旋转动画；

注意：在刷新完毕后，应当使用作用域的$broadcast()方法通知框架：

$scope.$broadcast("scroll.refreshComplete");

<!DOCTYPE html><html ng-app="myApp"><head><meta charset="UTF-8"><meta name="viewport" content="initial-scale=1,maximum-scale=1,user-scalable=no,width=device-width,height=device-height">    <script src="../../lib/js/ionic.bundle.min.js"></script>    <link rel="stylesheet" type="text/css" href="../../lib/css/ionic.min.css"></head><body  ng-controller="firstCtrl"><ion-header-bar class="bar-positive"><h1 class="title">ion-refresher</h1></ion-header-bar><ion-content><ion-refresher pulling-text="刷新..."on-refresh="doRefresh()" spinner="android"></ion-refresher><ul class="list"><li class="item" ng-repeat="item in items">{{item}}</li></ul></ion-content></body><script>angular.module("myApp", ["ionic"]).controller("firstCtrl", function($scope) {$scope.items = ['item1','item2','item3'];var base = 1;$scope.doRefresh = function() {for(var i=0;i<10;i++,base++)$scope.items.unshift(["item ",base].join(""));// Stop the ion-refresher from spinning//刷新完毕后，用$broadcast通知框架$scope.$broadcast("scroll.refreshComplete");};});</script></html>

6)上拉更新数据/ion-infinite-scroll

on-infinite(必须)——当滚动到底部时执行此表达式；

distance(可选)——距底部距离百分比,当距离底部超过此数据时，执行on-infinite,默认为1%；

icon(可选)——载入时显示的图标(默认是ion-load-d),ionic推荐使用spinner;

spinner(可选)——载入时显示的spinner,默认是ionSpinner;

immediate-check(可选)——是否在载入时立即检查滚动框范围。

注意：在更新完毕后，应当使用作用域的$broadcast()方法通知框架：

$scope.$broadcast("scroll.infiniteScrollComplete");

<!DOCTYPE html><html ng-app="myApp"><head><meta name="viewport" content="initial-scale=1,maximum-scale=1,user-scalable=no,width=device-width,height=device-height">    <script src="../../lib/js/ionic.bundle.min.js"></script>    <link rel="stylesheet" type="text/css" href="../../lib/css/ionic.min.css"></head><body ng-controller="firstCtrl"><ion-header-bar class="bar-positive"><h1 class="title">ion-infinite-scroll</h1></ion-header-bar><ion-content><ion-infinite-scroll   on-infinite="load_more();" icon="ion-load-a" distance="1%" immediate-check="true"></ion-infinite-scroll>        <ul class="list">            <li class="item"  ng-repeat="item in items">{{item}}</li>        </ul></ion-content></body><script>angular.module("myApp",["ionic"]).controller("firstCtrl",function($scope,$timeout){$scope.items = ['1111','22222'];var base = 0;$scope.load_more = function(){$timeout(function(){for(var i=0;i<3;i++,base++)$scope.items.push(["item ",base].join(""));$scope.$broadcast("scroll.infiniteScrollComplete");},500);};});</script></html>

7)$ionicScrollDelegate指令

$ionicScrollDelegate服务提供如下的常用方法：

resize()——重新计算容器尺寸。当父元素大小变化时，会调用此方法。

scrollTop([shouldAnimate])——回到顶部([动画效果])；

scrollBottom([shouldAnimate])——回到底部([动画效果]);

scrollTo(left,top,[shouldAnimate])——滚动到指定位置(水平值，垂直值，[动画效果])；

scrollBy(left,top,[shouldAnimate])——滚动指定偏移量(水平值，垂直值，[动画效果])；

getScrollPosition()——读取当前视图位置。返回值为一个JSON对象，具有left和top属性，表示x和y的值。

<!DOCTYPE html><html ng-app="myApp"><head><meta charset="UTF-8"><meta name="viewport" content="initial-scale=1,maximum-scale=1,user-scalable=no,width=device-width,height=device-height">    <script src="../../lib/js/ionic.bundle.min.js"></script>    <link rel="stylesheet" type="text/css" href="../../lib/css/ionic.min.css"></head><body ng-controller="firstCtrl"><ion-header-bar class="bar-positive">        <h1 class="title">$ionicScrollDelegate</h1>    </ion-header-bar><ion-content><ul class="list"><li class="item"  ng-repeat="item in items">{{item}}</li></ul></ion-content><ion-footer-bar class="bar-positive">        <a class="button" ng-click="gotop();">回到顶部</a>        <a class="button" ng-click="gobottom();">回到底部</a>        <a class="button" ng-click="getScrollPosition();">ScrollPosition</a>    </ion-footer-bar></body></html><script>angular.module("myApp",["ionic"]).controller("firstCtrl",["$scope","$ionicScrollDelegate",function($scope,$ionicScollDelegate){$scope.items = [];for(var i=0;i<100;i++)$scope.items.push(["item ",i+1].join(""));$scope.gotop = function(){$ionicScollDelegate.scrollTop(true);}$scope.gobottom = function(){$ionicScollDelegate.scrollBottom(true);}        $scope.getScrollPosition = function(){           console.log($ionicScollDelegate.getScrollPosition());        }}]);</script>
