</template>JS文件内容
export default {
name: 'HelloWorld',
data () {
return {
value: 0,
timer: '',//计时器
pwidth:0,//公告文本的宽度
windowWidth:document.documentElement.clientWidth,// 设备屏幕的宽度
}
},
mounted() {
let element = this.$refs.cmdlist;
this.pwidth = document.defaultView.getComputedStyle(element,'').width.split('px');
this.timer = setInterval(this.clickCommend, 20);
},
watch:{
value(newValue, oldValue) {
let allWidth= parseInt(this.windowWidth)+parseInt(this.pwidth[0]);
if(newValue <= -allWidth){
this.$refs.cmdlist.style.marginLeft = this.windowWidth+"px";
this.value = 0;
}
},
},
methods:{
clickCommend(e) {
let _this = this;
this.$nextTick(() => {
this.value -=1;
this.$refs.cmdlist.style.marginLeft = _this.windowWidth+this.value+"px";
});
},
menter(){
clearInterval(this.timer);
},
mleave(){
this.timer = setInterval(this.clickCommend, 20);
},
},
beforeDestroy() {
clearInterval(this.timer);
}
