I am using Cordova GA plugin to track events, but when testing in my browser I keep getting:
ReferenceError: plugin is not defined
I tried many ways to check if the plugin has been defined, but it still throws this error. How can I properly check if the plugin has been defined before I invoke the function?
To check if a JavaScript variable is undefined you can use
if (typeof myVariable === 'undefined') {
console.log('The variable is undefined.');
}
You may simply put a check before running your code:
if (window.plugin) {//I had assume that `plugin` is in global scope alert('plugin'); } else { alert('no plugin'); }
Using typeof
if('undefined' === typeof plugin) { alert('no plugin'); } else { alert('plugin ...'); }
