However in recent version of pdf.js, event are not visible outside of the library, except if the +* 'eventBusDispatchToDOM' has been set to true. +* +* We tried to set this option from outside of the library but without success, as our pdf viewer is in an iframe. +* There is no state of the iframe in which we can add an event listener to set the option. +* pdf.js has an event used to signal when we can set settings, called 'webviewerloaded'. +* This event is triggered in an EventListener attached to the 'DOMContentLoaded' event. +* So, to list options we had, we could: +* a) add an eventListener to the iframe document or window to react to 'webviewerloaded'. This doesn't work as +* document and windows are not the definitive ones and won't catche the event later. +* b) add an eventListener to the iframe to react to 'DOMContentLoaded', which doens't work too as our listener will be called +* after the pdf.js one. +* +* Finally the option was choosed to modify the default value of this option directly in pdf.js as no hook worked in the +* 'account_invoice_extract' module. +*/ |
