vue 路由判断方式_vue.js_

methods: { // 增加阅读人数 setpeople(){ console.log('定时器开启'); // overTimer 这个值可以写在data里面 //也可以直接用 const overTimer = setTimeout(() =>{},15000) this.overTimer = setTimeout(() => { this.artical_peo = this.artical_peo + 1 this.setpeo() }, 15000) }, // 修改阅读人数 setpeo(){ let params = `artical_peo=${this.artical_peo}&&id=${this.id}` this.axios.put('/read',params).then(res=>{ // console.log(res); }) },

 // 超时定时器 overTimer: 15000, sname:'' } }, // 监测路由跳转 beforeRouteEnter (to, from, next) { console.log('要跳到的页面',to.name) console.log('从那个页面跳过来',from.name) // console.log(next) next(vm =>{ //这里把获取到的from.name给到data里面定义的sname vm.sname = from.name // console.log(vm.sname); }); },

mounted () { // 判断当前跳转过来的页面如果是 scang 就不启动定时器 if(this.sname == 'Scang'){ //清除定时器 clearTimeout(this.setpeople) }else{ // 开启定时器 当点进来浏览够15秒后阅读量加一 this.setpeople() } },
