uploadFile
uploadFile(selector, filename)
Uploads the specified file (filename) to the form element associated with the selector.
This function is used to automate the upload of a file, which is usually handled with a file dialog in a traditional browser. Since there is no dialog in this headless mode, such an upload mechanism is handled via this special function instead.
Examples
var webPage = require('webpage');
var page = webPage.create();
page.uploadFile('input[name=image]', '/path/to/some/photo.jpg');
