marquee为跑马灯组件,用于展示一段单行滚动的文字。具体用法请参考marquee。
在pages/index目录下的hml文件中创建一个marquee组件。
- <!-- xxx.hml -->
- <div class="container">
- <marquee style="width: 100%;height: 80px; color: #ffffff; background-color: #0820ef;padding-left: 200px;">It's a racing lamp.</marquee>
- </div>
- /* xxx.css */
- .container {
- width: 100%;
- height: 100%;
- flex-direction: column;
- justify-content: center;
- align-items: center;
- background-color: #F1F3F5;
- }

marquee通过color和font-weight属性设置跑马灯中文本的颜色和字体粗细,通过border属性设置边框样式。
- <!-- xxx.hml -->
- <div class="container">
- <marquee class="custommarquee">It's a racing lamp.</marquee>
- </div>
- /* xxx.css */
- .container {
- width: 100%;
- height: 100%;
- flex-direction: column;
- justify-content: center;
- align-items: center;
- background-color: #F1F3F5;
- }
- .custommarquee {
- width: 100%;
- height: 80px;
- padding: 10px;
- margin: 20px;
- border: 4px solid #6712f1;
- border-radius: 20px;
- font-size: 40px;
- color: #ffffff; font-weight: bolder;
- font-family: serif;
- background-color: #1567f3;
- }

通过scrollamount、loop和direction属性实现跑马灯滚动时的移动距离、滚动次数和文字滚动方向。
- <!-- xxx.hml -->
- <div class="tutorial-page">
- <div class="mymarquee">
- <marquee loop="{{loopval}}" scrollamount="{{scroll}}" direction="{{isleft}}" class="marqueetext" id="testmarquee" onclick="makestart">
- Life is a journey, not the destination.
- </marquee>
- </div>
- <div style="width: 600px;height: 150px;flex-direction: row;justify-content: space-around;">
- <button onclick="setleft" value="left"></button>
- <button onclick="setright" value="right"></button>
- </div>
- </div>
- /* xxx.css */
- .tutorial-page {
- width: 750px;
- height: 100%;
- flex-direction: column;
- align-items: center;
- justify-content: center;
- background-color: #F1F3F5;
- }
- .marqueetext {
- color: #ffffff;
- font-family: serif;
- font-size: 37px;
- }
- .mymarquee {
- margin-top: 20px;
- width:100%;
- height: 100px;
- margin-left: 50px;
- margin-right: 50px;
- border: 1px solid #6712f1;
- background-color: #1567f3;
- border-radius: 15px;
- align-items: center;
- }
- button{
- width: 200px;
- height: 80px;
- margin-top: 100px;
- }
- // xxx.js
- export default {
- private: {
- loopval: -1,
- scroll: 10,
- isleft: "left",
- },
- onInit(){
- },
- setleft(e) {
- this.isleft = "left"
- },
- setright(e) {
- this.isleft = "right"
- },
- makestart(e) {
- this.$element('testmarquee').start()
- }
- }
当loop的值小于等于零时,跑马灯marquee将连续滚动。如果loop未指定,则默认为-1。

本场景可以控制跑马灯文字的滚动和暂停。
跑马灯的次数设置为1,在结束的时候触发finish事件使跑马灯的次数加1,字体颜色变为随机颜色,调用start方法使跑马灯再次开始滚动。
- <!-- xxx.hml -->
- <div class="tutorial-page">
- <div class="mymarquee">
- <marquee style="color: {{color1}}" loop="{{loopval}}" scrollamount="{{scroll}}" direction="{{isleft}}" class="marqueetext"
- id="testmarquee" onfinish="setfinish">
- Life is a journey, not the destination.
- </marquee>
- </div>
- <div style="width: 600px;height: 150px;flex-direction: row;justify-content: space-around;">
- <button onclick="makestart" value="start"></button>
- <button onclick="makestop" value="stop"></button>
- </div>
- </div>
- /* xxx.css */
- .tutorial-page {
- width: 750px;
- height: 100%;
- flex-direction: column;
- align-items: center;
- justify-content: center;
- }
- .marqueetext {
- font-size: 37px;

- export default {

- loopval: 1,
- scroll: 8,
- color1: 'red'
- },
- onInit(){
- },
- setfinish(e) {
- this.loopval = this.loopval + 1,
- this.r = Math.floor(Math.random()*255),
- this.g = Math.floor(Math.random()*255),
- this.b = Math.floor(Math.random()*255),
- this.color1 = 'rgba('+ this.r +','+ this.g +','+ this.b +',0.8)',
- this.$element('testmarquee').start(),
- this.loopval = this.loopval - 1
- },
- makestart(e) {
- this.$element('testmarquee').start()
- },
- makestop(e) {
- this.$element('testmarquee').stop()
- }
- }
