Mark of the Web on Xpages

316 Views Asked by Raphael Maycon At 20 October 2024 at 20:13

So I need to send an attachment to a document, but I have to validate if it is larger than 15mb , for so I am using this code in javascript to get the file :

var objFSO = new ActiveXObject("Scripting.FileSystemObject"); 
            var filePath = document.getElementById(fileid).value;
            var objFile = objFSO.getFile(filePath);
            var fileSize = objFile.size; //size in kb

I'm having an error when I try to create ActiveXObject because my site is not "trusted " by not having a Mark of the Web

<!doctype html>
<!-- saved from url=(0023)http://www.contoso.com/ -->
<html>
  <head>
    <title>A Mark of the Web Example.</title>
  </head>
  <body>
     <p>Hello, World</p>
  </body>
</html>

so I wonder if it is possible to have a mark of the web in a XPage and how I could put it the body of the XPage.

My client does not want to manually place the security option , but want to use IE , please help me haha.

If there is another way to check the file size when selecting a file using javascript would be interesting.

You can create a Java validator for old browsers, but if the Javascript API is available (modern browsers), use it.

public class Attachment implements Validator {

    private final static long BYTES_IN_1_MB     = 1048576;
    private final static long MAX_MB_ALLOWED    = 10;
    private final static String MSG_ERROR_SIZE  = "File size cannot be bigger than {0} MBs";

    public void validate(FacesContext fc, UIComponent uiComp, Object attach)
            throws ValidatorException {     

        FacesMessage msg;

        UploadedFile upFile = (UploadedFile) attach;
        long max_bytes = BYTES_IN_1_MB * MAX_MB_ALLOWED;

        // SIZE:        
        if (upFile.getContentLength() > max_bytes) {
            String msgError = MSG_ERROR_SIZE.replace("{0}", String.valueOf(MAX_MB_ALLOWED));
            msg = new FacesMessage(FacesMessage.SEVERITY_ERROR, msgError, msgError);        
            throw new ValidatorException(msg);
        }       

    }   

}

These validators need to be added into the faces-config.xml

  <validator>
    <validator-id>attachmentValidator</validator-id>
    <validator-class>com.faces.validator.Attachment</validator-class>
  </validator>

Then you can add the validator into the fileUpload field:

<xp:this.validators>                                    
    <!--    Validator for Attachments   -->
    <xp:validator validatorId="attachmentValidator">
    </xp:validator>
</xp:this.validators>

Try this code to check file size in HTML5 should work in all modern browsers

var fileSize=0
if (typeof FileReader !== "undefined") {
    var filePath = document.getElementById(fileid);
  fileSize= filePath.files[0].size; 
}

Check the filesize var for the max limit of you file.

Use this code if the browser is IE10 or newer and your old code if the browser is older.
