Question

我有这个学校的任务来制作这个表格。如果必须填写*标记，则必须填写*标记必须填写它（必须是红色）。这就是全部。不要对我很难。

    <script type="text/javascript" src="http://code.jquery.com/jquery-1.7.2.min.js"></script>
    <script type="text/javascript">
        $(document).on("ready", geladen);
        function geladen(){

             console.log("geladen");
            // zodra een veld verlaten wordt moet gecontrolleerd worden
        }
        function controlleerVerplicht(event){
            // controlleer of er niets is ingevuld
                    if ( $('input*').val().length < 1 ){

            $("*").css("border", "2px solid red").next().text("Dit veld is verplicht");

            }

            else ($("*").css("border", "2px solid green").next().text("Het is succesvol gedaan"));
                // en zet in dat geval de tekst "Dit veld is verplicht" in de span in dezelfde paragraaf
            }

        function checkAcceptatie(){

            console.log("check acceptatie");

            if ($("input:checked").length==1){

                $(":submit").removeAttr("disabled");

                }
