Examples of org.apache.click.control.FileField

org.apache.click.control.FileField
ta.apache.org/commons/fileupload/">FileUpload library to provide file processing functionality.
You can control the {@link org.apache.click.service.CommonsFileUploadService#sizeMax maximum request size}and {@link org.apache.click.service.CommonsFileUploadService#fileSizeMax maximum file size}by configuring {@link org.apache.click.service.CommonsFileUploadService}.
Note Browsers enforce the JavaScript value property as readonly to prevent script based stealing of users files.
You can make the file field invisible by setting the CSS display attribute, for example:
```
 <form method="POST" enctype="multipart/form-data"> <input type="file" name="myfile" style="display:none" onchange="fileName=this.value"> <input type="button" value="open file" onclick="myfile.click()"> <input type="button" value="show value" onclick="alert(fileName)"> </form> 
```
