# element-ui 弹窗的 this.$confirm 框报错 Uncaught (in promise) cancel
这是因为你点击了取消或者是关闭弹窗，但是你没有写 catch。正确的写法是
this.$confirm('确定清空试题篮所有试题？', '提示', { | |
type: 'warning' | |
}).then(() => { | |
localStorage.setItem('chosedResourceids',""); | |
localStorage.setItem('PaperMsg',""); | |
if( sessionStorage.getItem('PaperMsg')==''){ | |
this.$message({ | |
message: '操作成功', | |
type: 'success' | |
}); | |
this.$router.push({name:'资源中心',query:{kind:40}}) | |
} | |
}).catch(() => { | |
}); // 一定别忘了这个 |
