How to set text in file (html input type)

How can we set text in html file uploader.

Is it possible开发者_Python百科 using JavaScript?

You cannot. The value attribute is ignored, and the DOM value property is readonly.

Otherwise <input style="display: none" type="file" name="mine-now" value="path-to-some-common-sensitive-file">

You cannot set this (security reasons - only user can select file in browser ), but if you need it you can clear this field using this script:

$get('FileUploadCtrlId').outerHTML="<input type=file style='WIDTH: 400px' id ='FileUploadCtrlId'>"
