Just open the Plugin page by entering about:plugins in Google search box and hitting Enter. It’s much easier to disable it in Chrome that is lower than version 57. Option 1 – Disable Chrome PDF viewer from the plugins page Disable Chrome PDF viewer from Content Settings.Disable Chrome PDF viewer from the plugins page.In such case, you may want to know how to disable the Chrome PDF viewer. However, it blocks the access of your other PDF software like Adobe Reader at the same time. (See the event object for details of the Acrobat events.) Beginning with Acrobat 7.Chrome built-in PDF viewer gives us the convenience to open PDF files. These events include batch processing, application start or execution within the console. P: Even though this property does not change the document, it can permanently change a user’s application preferences.įor security reasons, this property or method may be available only during certain events. (In Adobe Reader, the document requires specific rights to be saved.) If the document is subsequently saved, the effects of this method are saved as well. X indicates the item is deprecated.ĭ: Writing to this property or method dirties (modifies) the PDF document. If the first column is blank, no compatibility checking is necessary. Before accessing the property or method, the script should check that the forms version is greater than or equal to that number to ensure backward compatibility.įor example: if (typeof app.formsVersion != "undefined" & app.formsVersion >= 8.0) For Acrobat 8.0, there are some compatibility issues with older versions. If the number is specified, the property or method is available only in versions of the Acrobat software greater than or equal to that number. The #.# version number indicates the product version a property or method became available. The quick bar shown here has descriptive column headings that are not shown in the reference. trustedFunction.Īt the beginning of most property and method descriptions, a small table or quick bar provides a summary of the item’s availability, usage recommendations, type, and access. Trusted functions allow privileged code-code that normally requires a privileged context to execute-to execute in a non-privileged context. You can execute security-restricted methods through menu events in one of the following ways:īy opening the JavaScript category of the Acrobat preferences and checking the item named “Enable Menu Items JavaScript Execution Privileges”.īy executing a specific method through a trusted function (introduced in Acrobat 7.0). Beginning with Acrobat 7.0, execution of JavaScript through a menu event is no longer privileged. In Acrobat versions earlier than 7.0, menu events were considered privileged contexts. The description of each security-restricted method indicates the events during which the method can be executed.īeginning with Acrobat 6.0, security-restricted methods can execute without restrictions if the document certifier’s certificate is trusted for running embedded high privilege JavaScript. All other events (for example, page open and mouse-up events) are considered non-privileged. These methods can be executed only in a privileged context, which includes console, batch and application initialization events. Some JavaScript methods, marked by an S in the third column of the quick bar, have security restrictions. Privileged versus non-privileged context ¶ Again, for a JavaScript solution, all these factors must be considered.įor documentation on core JavaScript, the reader is directed to the Mozilla Developer Center. Additionally, some APIs are restricted to Acrobat Pro and some cannot be used by Adobe Reader, while others can be used in Adobe Reader only when the document has the appropriate Reader Extension Rights. Most JavaScript API are documented for all versions of Acrobat and Adobe Reader, while others are only defined in later versions. The choice of target application determines, by the table above, the version of JavaScript you should use. When developing a JavaScript solution, you must have a minimum Acrobat (or Adobe Reader) version in mind. The most recent version of Acrobat now uses JavaScript 1.7. In Acrobat 5.0, there was a major effort to extend core JavaScript, then version 1.5, to include much of the functionality of the application and its plug-ins. Initially, JavaScript version 1.2 was used, as the table below shows. JavaScript functionality was added to this version by means of the “Acrobat Forms Author Plug-in 3.5 Update”. The Acrobat extensions to core JavaScript date back to Adobe Exchange 3.01.
