Save current route url to localStorage

[Tegola]

Hello,
since the only way to restore the state of a web app added to the iOS homescreen is by using routing, I'm searching for a way to store the current route's hash url to localStorage, so I can load it the next time the user opens the app.

The easiest way to store the url is:

localStorage.setItem('url', location.hash.substr(1));

However, I need to save this url everytime the app launches a "redirectTo(...)". I didn't find a specific event or a way to intercept it. How do you do it?

Thanks

Ext.define('controller',{
    config:{
        before:{
            showUser:'storeUrl'
        },
        routes:{
            'user/:id': 'showUser'
        }
    },
    storeUrl:function(action){
        localStorage.setItem('url', location.hash.substr(1));
        action.resume();
    }
})

Thanks for your reply.

That means that I need to add a "before" config for every action. There's a clean way to launch it before ANY action?

Here's my dirty method:

if (Ext.feature.has.History) {
	window.addEventListener('hashchange', Ext.bind(saveUrl, this));
}

function saveUrl(location){
	var hash;
		

	if (location.hash) { // object
		hash = location.hash;
	} else if (location.newURL)  { // hashchange event
		var anchor = document.createElement('a');
		anchor.href = location.newURL;
		hash = anchor.hash;
		delete anchor;
	}
	localStorage.setItem('url', hash.substr(1));
}
