Allow/Disallow scripts while running PDF

[Gowtham Lcs]

Hi Team,

We would like to get the consent from user before running the script embedded in PDF document while previewing the PDF. For, example now I am uploading the attached file and viewing the preview throws general browser alert, on pressing ok it starts running the script on the preview. 

But we would like to get the consent from user to run or stop the script further. Do we have any settings to control this behavior. Please share. Thanks. 

Regards,

Gowtham C

Hello,

You can use the following code in a config file:

var firstRun = true;

var allowJavaScript = false;

 

var onTriggered = Actions.JavaScript.prototype.onTriggered;

Actions.JavaScript.prototype.onTriggered = function(target, event) {

  if (firstRun) {

    firstRun = false;

    allowJavaScript = window.confirm('Allow document JavaScript?');

  }

  if (!allowJavaScript) {

    CoreControls.disableEmbeddedJavaScript();

    return;

  }

 

  onTriggered.apply(this, arguments);

};

This was done using https://www.pdftron.com/api/web/CoreControls.html#.disableEmbeddedJavaScript__anchor

See config file guide here: https://www.pdftron.com/documentation/web/guides/config-files/
