It is also possible that when you click on a link to a PDF document in a web page, your browser will download the PDF, and cause the standalone PDF Reader to display the document.Ģ Kinds of PDF Readers: Plugin vs Built-in Despite this, it is still possible that a standalone PDF Reader application is on your computer, and can be used to display PDF documents. If the instantiation works, then the browser probably supports PDF documents.Ħ) Any Browser + disabled PDF viewer(s): if all the PDF Readers within your browser are disabled, then PluginDetect will most likely not be able to detect them. If there is no "application/pdf" item in the array, PluginDetect will try to instantiate an empty PDF file in the web page. In cases such as this, the navigator.mimetypes array may or may not have an "application/pdf" item. But so far, up to and including Internet Explorer 10, things appear to work.ĥ) Non - Internet Explorer browsers + built-in PDF viewer: can be detected by PluginDetect. Future versions of IE may or may not allow detection.
Note: due to the unconventional techniques used to detect non-Adobe Reader plugins for Internet Explorer, there is no guarantee that this detection is future proofed. It does not appear to be a high priority for them. The plugin authors could make their PDF reader plugin more easily detectable via Javascript in IE if they wanted to, but most of them have not bothered to do so. Either the plugin authors need to give security pre-approval to their plugin (like Adobe does for their plugin), or the user will have to give security approval by clicking on the popup. The popup may occur because a 1x1 tag containing a PDF was inserted into the web page, and the tag was not security approved yet to display PDF documents. In this case, unfortunately, it is very possible that Internet Explorer may trigger a security popup. In order to do this detection, ActiveX has to be enabled and ActiveX filtering has to be disabled.Ĥ) Internet Explorer + non-Adobe PDF Reader plugins: can be detected by PluginDetect, but only if the detectNonAdobeIE input argument is true, and if ActiveX is enabled, and ActiveX Filtering is disabled.
The Adobe Reader plugin is an approved control in IE 7+, and hence no security popup appears in the browser when the ActiveX control is instantiated. We instantiate the ActiveX object to verify the plugin presence. We simply check the mimetypes array to verify that "application/pdf" is present and enabled.ģ) Internet Explorer + Adobe Reader plugin: can be detected by PluginDetect for IE 6+. We simply check the mimetypes array to verify that "application/pdf" is present and enabled.Ģ) Non - Internet Explorer browsers + non-Adobe PDF Reader plugins: can be detected by PluginDetect. The Generic PDF detector covers a number of different cases:ġ) Non - Internet Explorer browsers + Adobe Reader plugin: can be detected by PluginDetect. It will do so regardless of whether your browser is using the Adobe PDF Reader plugin, a non-Adobe PDF plugin, or a PDF viewer that is built in to the browser. PluginDetect's Generic PDF Reader Detector will try to determine if your browser can display a PDF document.

Make sure that the DummyPDF input argument in your Javascript code specifies the correct filename and path. ģ) write the Javascript code that calls the appropriate PluginDetect commands. The download page will allow you to customize the PluginDetect script to include whatever features you desire. The DummyPDF file is used by PluginDetect in order to do NOTF (not on the fly) detection.ĭownload the PluginDetect script itself. In order to do generic pdf detection in a browser, you will need several things:ġ) download the DummyPDF file (just right click and Save As).
