报错详情:
[Vue warn]:
Error in callback for immediate watcher "fileList":
"TypeError: Cannot create property 'uid' on string 'url'"
...
报错原因:
TypeError: Cannot create property ‘xxx’ on string ‘xxxx’,此类错误是赋值的类型错误,
如以上示例错误,在使用ElementUI的upload组件时,把字符串列表赋值给了
fileList
,而
fileList
需求的是对象的列表
示例错误代码:
pictureList = ['url1', 'url2'];
this.fileList = pictureList;
示例正确代码:
pictureList = ['url1', 'url2'];
this.fileList = pictureList.map(item => {
return {
name: item,
url: item
}
});
