Vue代码重用总结

1. upload上传方法

	const params = new FormData();
    params.append('file', file);
    params.append('type', 'finance');
    params.append('publicFlag', false);

2. 多文件上传修改的回显

response.data.attachment = response.data.attachment ? response.data.attachment.split(',').map((b) => ({ url: b })) : [];

3. 数组拼接字符换

join(",")

4. 数组合并

concat
