A: jQuery does not have ng-repeat but if you need how to get x.something value in address variable you can use JavaScript interpolation using back-ticks.
let address = <?=ROOT_ADDRESS?>/api/get_now/{{x.something}};


$(document).ready(function () {
    let x = {something:"123"};
    let address = `<?=ROOT_ADDRESS?>/api/get_now/${x.something}`;
    alert(address)
    $.ajax({
        url: address,
        success: function (data) {
            data = $.parseJSON(data);
        }
    });
});
