幻灯片控件:
跑马灯控件:
弹出提示框:prompt.showToast()
弹出对话框:prompt.showDialog()
在制作提示框的时候,首先制作一个菜单栏选项,弹出菜单栏仅有当调试点击后才触发显示出来 不占用原有视图空间.弹出菜单栏的位置默认以(0,0)为基准点,为了更好的用户体验,也可以自行设置弹出位置(如下图)
介绍一种跳转页面新方法:路由跳转页面(具体见代码): import router from '@system.router'; //通过路由跳转页面
router.push({ uri: 'pages/jumpone/jumpone'}) //路由的方法
主页面的js业务逻辑层:
- import prompt from '@system.prompt';
- import router from '@system.router'; //路由 通过路由跳转页面
- export default {
- data: {
- title: 'World',
- imgdatas:[{
- "src":"http://ttjib3.natappfree.cc/images/12.jpeg"
- },
- {
- "src":"http://ttjib3.natappfree.cc/images/13.jpg"
- },
- {
- "src":"http://ttjib3.natappfree.cc/images/14.jpg"
- },
- {
- "src":"http://ttjib3.natappfree.cc/images/15.jpg"
- },
- {
- "src":"http://ttjib3.natappfree.cc/images/16.png"
- }]
- },
- showmenu() {
- //弹出显示菜单 首先要获取这个组件用 this.$element
-
- //this.$element("menueone").show();
-
- //弹出的具体位置 默认时以(0,0)为基准点
- this.$element("menueone").show({
- x:0,
- y:0
- });
- },
- changemenu(e) {
- let name = e.value //这里的value就是hml中的value
- //鸿蒙的提示框
- prompt.showToast({
- message:name
- });
- if (name == "太和殿")
- {
- router.push({ //路由的方法
- uri: 'pages/jumpone/jumpone'
- });
- }
- else if(name == "养心殿")
- {
- router.push({ //路由的方法
- uri: 'pages/jumptwo/jumptwo'
- });
- }
- else if(name == "乾清宫")
- {
- router.push({ //路由的方法
- uri: 'pages/jumpthree/jumpthree'
- });
- }
- }
-
- }
主页面视图层:
- "container">
- "topview">
- --幻灯片组件-->
-
"image-animator" duration="5s" fixedsize="false" images="{{imgdatas}}"> -
-

- >菜单
-
- onselected="changemenu">
- <option value="太和殿">太和殿option>
- <option value="养心殿">养心殿option>
- <option value="乾清宫">乾清宫option>

主页面css属性设置:

跳转页面一的js业务逻辑层:
- import prompt from '@system.prompt';
-
- export default {
- data: {
- title: 'World'
- },
- changmes() {
- //1.弹出提示框
- // prompt.showToast()
- //2.弹出对话框
- prompt.showDialog({
- title:"问题",
- message:"你今年是否有600岁?",
- buttons:[{"text":"是","color":"#000000"},{"text":"否","color":"#000000"}],
- //用successs追踪对话框
- success:function(data){
- if(data.index==0){
- prompt.showToast({
- message:"你点击了是按钮"
- })
- }
- if(data.index==1){
- prompt.showToast({
- message:"你点击了否按钮"
- })
- }
- }
- })
- }
- }
跳转页面一的视图层:

跳转页面三的js业务逻辑层:

- {"cname":"故宫建筑","cimg":"/common/gugong.png","lname":[]},
- {"cname":"故宫历史","cimg":"/common/gugong.png","lname":[]}
- ]
- },
- changemenu(e){
- router.push({
- uri:'pages/gugongwenchuang/gugongwenchuang'
- })
- }
- }
跳转页面三的视图层:

for ="{{listdatas}}"> -
group class="group"> --高度不需要给出 会自适应大小--> -
"listitem" > -
"img1" src="{{$item.cimg}}"> -

"listitem1" onclick="changemenu"> -
"img1" src="{{cvalue.icon}}"> -
"txt2" >{{cvalue.fname}} -
-

跳转页面三的css属性设置:
- .container {
