Question

I have this section of code that saves a list item on click to localStorage based on the list item’s id number. On a different page I am then able to load whatever list items were saved.

var save1075 = $('#store-1075').get(0);
$('#store-1075').on('click', function () { 
    var storeStorageKey1075 = $(this).attr('id'); 
    localStorage.setItem('storeStorageKey1075', $(this).attr('id'));
    localStorage.setItem('storeStorageKey1075', this.innerHTML);
});

if ( localStorage.getItem('storeStorageKey1075') ) {
save1075.innerHTML = localStorage.getItem('storeStorageKey1075'); 
}

var storeStorageKey1075 = $(this).attr('id');
    if ( localStorage.getItem('storeStorageKey1075') ) {
    storeStorageKey1075 = localStorage.getItem('storeStorageKey1075');

}

Right now I have to repeat that chunk of code for every individual id number and I’m trying to instead make the id number a variable that loops through all possible id numbers when clicked but only saves the id of that specific one. Maybe something along the lines of this:

var id = //some sort of loop or array of possible ids.
var save = $('#store-'+id).get(0);
$('#store-'+id).on('click', function () { 
    var storeStorageKey = $(this).attr('id'); 
    localStorage.setItem('storeStorageKey', $(this).attr('id'));
    localStorage.setItem('storeStorageKey', this.innerHTML);
});

if ( localStorage.getItem('storeStorageKey') ) {
save.innerHTML = localStorage.getItem('storeStorageKey'); 
}

var storeStorageKey = $(this).attr('id');
    if ( localStorage.getItem('storeStorageKey') ) {
    storeStorageKey = localStorage.getItem('storeStorageKey');

}

Each of the list items has the same prefix of “store-” and the numbers are in no specific order but randomly generated each time a new store location is created.

The obvious thing to do is to add a class but you could also:

var elems = $( "[id^='store']")

elems.on( "click", function() {//Save html on click
    localStorage.setItem( this.id, this.innerHTML );
});

    //Retrieve html
elems.each( function() {
    var html = localStorage.getItem( this.id );

    if( html ) {
        $(this).html( html );
    }
});
