The navigation service supports different kinds of pages in Lightning. Each page reference type supports a different set of attributes and state properties.
Instead of using force:navigateToURL, we recommend navigating to web pages using the lightning:navigate component with the standard__webPage page type.
This code shows examples of navigating to a web page using the old force:navigateToURL event.
// Old way to navigate to a web page
$A.get("markup://force:navigateToURL").setParams({
url: 'https://salesforce.com',
}).fire();
Replace the previous code that uses force:navigateToURL with the following code. This example shows how to navigate to a web page using the standard__webPage page type. It assumes that you added <lightning:navigation aura:id="navigationService" /> in your component markup.
cmp.find("navigationService").navigate({
type: "standard__webPage",
attributes: {
url: 'https://salesforce.com'
}
});
