Detect if Cordova plugin exists

Question

Is there a way to tell if a specific Cordova plugin is available to be called in Cordova 2.5.0? Cordova.exec takes in a successFunction and a failFunction but the failFunction is only called if the native code executes. Is there a way to receive an error or callback if the receiving function doesn't exist? I'm looking for a solution that works with a remove URL loaded into WebView

Answer 1

For a quite simpler (and cleaner) solution, you can also use this method :

var plugins = cordova.require("cordova/plugin_list").metadata;

You'll get an object looking like that :

{
    'cordova-plugin-network-information': "1.0.0",
    'cordova-plugin-whitelist': "1.0.0"
}

As any normal variable, you can then check if it's defined :

if (typeof plugins['cordova-plugin-whitelist'] === "undefined")
{
    // This plugin is missing
}

Answer 2

you can do a setTimeout for 100 ms before trying to access the plugin, and on success/failure of the plugin cancel the timeout. if the timeout triggers - the plugin is not installed.
