this.chatTimer = setInterval(() => { console.log(this.chatTimer); this.chatMsg(); }, 1000);
而後再組件銷燬前進行清除vue
beforeDestroy() { clearInterval(this.chatTimer); this.chatTimer = null; }
根據 setInterval 返回的 id 打印來看,請除定時器並無成功
this
可是這樣不行,定時器在局部更新的時候會屢次賦值.更改了一種寫法,加了一重判斷以後依舊沒法解決.code
if (!this.chatTimer) { this.chatTimer = setInterval(() => { console.log(this.chatTimer); this.chatMsg(); }, 1000); }
使用全局變量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); })
