import Navigator from "./vendors/@oom/page-loader/src/navigator.js" ;
const nav = new Navigator ( async ( load , event ) => {
//Load the page
const page = await load ( ) ;
await page . replaceStyles ( ) ; //Load the new css styles defined in <head> not present currently
await page . replaceScripts ( ) ; //Load the new js files defined in <head> not present currently
await page . replaceContent ( "main" ) ; //Replace the <main> element
await page . updateState ( ) ; //Update the page status (change url, title etc)
await page . resetScroll ( ) ; //Reset the scroll position
} ) ;
//Init the navigation, capturing all clicks in links and form submits
nav . init ( ) ;
//Optionally, you can filter links and forms to disable this behaviour
nav . addFilter ( ( el ) => ! el . classList . contains ( "no-loader" ) ) ;
//For example, to disable forms:
nav . addFilter ( ( el ) => el . tagName !== "FORM" ) ;
//Subscribe to events
nav . on ( "error" , ( err ) => console . error ( err ) ) ;
//You can go manually to other url when you want
nav . go ( "https//example.com/page2.html" ) ;
//Or submit a form via ajax
const form = document . getElementById ( "my-form" ) ;
nav . submit ( form ) ;
//And handle downloads (links with download attribute)
nav . download ( async ( download , event , link ) => {
link . classList . add ( "downloading" ) ;
await download ( ) ;
link . classList . remove ( "downloading" ) ;
