由于我设定的页面默认进入的时候加载一次刷新函数,刚开始刷新完之后lifeList还不能及时更新过来,且我给该组件上加了v-else等判断,所以会报错:
Error in mounted hook: "TypeError: Cannot read property 'onTopLoaded' of undefined"
获取当前this.$refs可以看到有这个dom元素 loadTop
但是this.$refs.loadTop打印则为undefined
解决办法:
loadTop(){
this.$store.dispatch('refreshLifeList', {
city: this.city,
country: this.country,
category: this.category,
page: 0,
size: this.size
});
this.page++;
if(this.lifeList.length>0){ //这个判断是新加的
this.$refs.loadTop.onTopLoaded();
}
this.refreshComplete = true;
setTimeout(() => {
this.refreshComplete = false;
}, 2000)
},
给loadTop函数里的
this.$refs.loadTop.onTopLoaded(); 做一个判断即可。 或者在html中不要加v-if和v-else是否展示的判断都可。
