File uploading is a feature we often use. But why do we want to make such a prototype? Can't Axure set text field to file type and then realize the feature of file selection and uploading? Isn't it possible to call JavaScript code in Axure to realize the uploading feature?

1. First of all, the file uploading interface of the system cannot be modified freely. The button style may not match the UI style we want. Secondly, the prototype generated by Axure cannot open local files, so there is no good interaction effect.

2. Why not use JavaScript calls? Although Axure can implement JavaScript calls and change the UI of the upload button, it can't open local files and doesn't have a good experience.

Therefore, in order to set the style and interaction at will. We can simulate the high-fidelity file uploading interface.
