here is the scenario:

btnplus function - inserts some new data into a database

it calls get_atitles - which is also an ajax call to populate a div with the new set of data

when the div is populated - go_find should find a specific element inside the new set. This is not an ajax

problem - go_find starts before get_atitles is finished so it cannot find the required data

I tried to place async await on various places - without success

so how to call go_find after get_atitles is completed ?

$(btnplus).on('click', function(){
    ...
    $.post('pro.php', {fn: 'btn_plus_fi', args: [path]}, async function(data){
        // some new data is added to database
        await get_atitles(); // load the new set of data into a div
        go_find(str); // find a specific data inside a new set
    });
});

function get_atitles(){
    ...
    $.post('pro.php', {fn: 'get_atitles', args: [par]}, function(data){
        atitles.html(data);
    });
}

function go_find(str){
    // find something inside `atitles`
}
