WordPress函数在特定日期添加一个类

This code is used to add a class on a specific day. On that day, the class is well-added, but the next day this class disappears. Which is the right code? I want to develop a function in a WordPress web to add a class on a specific day that does not disappear the day after.

function ProgramarBorrado(){
        ?> 
        <script type="text/javascript">
            var day = (new Date).getDate(); //Get today
            var month = (new Date).getMonth()+1; //Get this month
            var year = (new Date).getFullYear(); //Get this year
            var lista = [];
            if ((day == 1) && (month == 4) && (year==2019)) {  //Push ID on a list
            lista.push('#borrar22marc');
            }
            if ((day == 6) && (month == 4) && (year==2019)) {
            lista.push('#borrar6abril');
            }
            if ((day == 5) && (month == 5) && (year==2019)) {
            lista.push('#borrar5maig');
            }
            if ((day == 19) && (month == 5) && (year==2019)) {
            lista.push('#borrar19maig');
            }
            if ((day == 8) && (month == 6) && (year==2019)) {
            lista.push('#borrar8juny');
            }
            if ((day == 10) && (month == 8) && (year==2019)) {
            lista.push('#borrar10agost');
            }

            lista.forEach(function(element) {
                  jQuery(element).addClass('borrar-programado');// For each element on the list add a class on the ID
                });

        </script>
    <?php
}
add_action('wp_footer', 'ProgramarBorrado');

This code is to add a class on a specific day. When that concrete day arrives he adds the class well, but then the next day this class does not appear anymore. What would be the correct code?

What I want to say is that the next day is eliminated, and what I want is that it never be eliminated.

Why not extending your check for the specific dates? E.g.

if ((day == 10 || day == 11) && (month == 8) && (year==2019)) {
    lista.push('#borrar10agost');
}

You can do it as:

Updated:

function ProgramarBorrado(){
        ?> 
        <script type="text/javascript">
            var day = (new Date).getDate(); //Get today
            var month = (new Date).getMonth()+1; //Get this month
            var year = (new Date).getFullYear(); //Get this year
            var lista = [];
            if ( isNextDay(1, day ) && (month == 4) && (year==2019)) {  //Push ID on a list
              lista.push('#borrar22marc');
            }elseif (isNextDay(6, day ) && (month == 4) && (year==2019)) {
              lista.push('#borrar22marc');
              lista.push('#borrar6abril');
            }elseif (isNextDay(5, day ) && (month == 5) && (year==2019)) {
              lista.push('#borrar22marc');
              lista.push('#borrar6abril');
              lista.push('#borrar5maig');
            }elseif (isNextDay(19, day ) && (month == 5) && (year==2019)) {
              lista.push('#borrar22marc');
              lista.push('#borrar6abril');
              lista.push('#borrar5maig');
              lista.push('#borrar19maig');
            }elseif (isNextDay(8, day ) && (month == 6) && (year==2019)) {
              lista.push('#borrar22marc');
              lista.push('#borrar6abril');
              lista.push('#borrar5maig');
              lista.push('#borrar19maig');
              lista.push('#borrar8juny');
            }elseif (isNextDay(10, day ) && (month == 8) && (year==2019)) {
              lista.push('#borrar22marc');
              lista.push('#borrar6abril');
              lista.push('#borrar5maig');
              lista.push('#borrar19maig');
              lista.push('#borrar8juny');
            lista.push('#borrar10agost');
            }else{
              lista.push('#borrar22marc');
              lista.push('#borrar6abril');
              lista.push('#borrar5maig');
              lista.push('#borrar19maig');
              lista.push('#borrar8juny');
              lista.push('#borrar10agost');
           }

            lista.forEach(function(element) {
                  jQuery(element).addClass('borrar-programado');// For each element on the list add a class on the ID
                });

       // check for next day
       function isNextDay(day, cday){
         if(cday == day || cday == (day+1)){
           return true;
         }else{
          return false;
         }
       }

        </script>
    <?php
}
add_action('wp_footer', 'ProgramarBorrado');

Note: isNextDay() returns boolean (true/false) as condition meets.
