How to call a custom function implemented inside config.js from outside the iframe

[Euan Carmichael]

Q: I have implemented a custom function inside my config.js file that I want to call from outside the WebViewer iframe, how can I do this?

A: To achieve this you can append the function to the readerControl object inside the iframe and then access the function via that object:

Config.js:

$(document).on('viewerLoaded',
  function() {

    readerControl.myFunction = function() {  

    console.log('hello world');

  };

});

outside the iframe:

$(viewerElement).on('documentLoaded',
function() {

  myWebViewer.getInstance().myFunction();

});

See the user-guides for more information on accessing the WebViewer objects from outside the iframe: https://www.pdftron.com/documentation/web/guides/fundamentals/html-structure
