this.chatTimer = setInterval(() => { console.log(this.chatTimer); this.chatMsg(); }, 1000);
而后再组件销毁前进行清除vue
beforeDestroy() { clearInterval(this.chatTimer); this.chatTimer = null; }
根据 setInterval 返回的 id 打印来看,请除定时器并无成功
this
可是这样不行,定时器在局部更新的时候会屡次赋值.更改了一种写法,加了一重判断以后依旧没法解决.code
if (!this.chatTimer) { this.chatTimer = setInterval(() => { console.log(this.chatTimer); this.chatMsg(); }, 1000); }
使用全局变量blog
window.chatTimer = setInterval(() => { console.log(window.chatTimer); this.chatMsg(); }, 1000);
destroyed() { clearInterval(window.liaotianTimer); },
const chatTimer = setInterval(() => { console.log(chatTimer); this.chatMsg(); }, 1000); this.$once('hook:beforeDestroy', () => { clearInterval(chatTimer); })
