is there a way to make $("js-page-alerts") into a variable?

<script>
    $(document).ready(function () {
        if ($(".js-page-alerts") != null || $(".js-page-alerts") != "undefined") {
            if ($.trim($(".js-page-alerts").text()).length > 10) {
                $(".ins-alert").css("display", "inherit");
            }
        }
    });
</script>  

Thanks

You can try with the below code

 <script>
        $(document).ready(function () {
            var pgalert = $(".js-page-alerts");

            if (pgalert != null || pgalert != "undefined") {
                if ($.trim(pgalert.text()).length > 10) {
                    $(".ins-alert").css("display", "inherit");
                }
            }
        });
</script>

Hi,

Are you trying to check the existence of element? try using .length

if($(".js-page-alerts").length)
{}

Hi sayitfast,

We declare a JavaScript variable with the var keyword.
