Recently, the mobile terminal was developed, and the customer requested to click upload at the uploading point, and the photo album and photo function would pop up directly. After the test, it is found that the file type limit can be added, but different system calls are different.
Differences: Apple displays for files and photos, Android for photo albums and photos (one way that comes to mind is custom calls). But here is the system difference, we will ignore it for now.
When uploading files, you need to limit the specified file types.
<input type="file" accept="image/*" />
accept indicates that the file type can be uploaded, image indicates a picture, and * indicates all supported formats.
accept can specify the following information:
