將您的第一個(gè)條件限制為小于 2019，否則對(duì)于 2019、2020 和其他更大的值也將成立。改為if(year >= 14)_if(year >= 14 && year <2019)


function myfun(){

   var year = document.getElementById('age').value;

   var yoad;

     if( year >= 2014 && year < 2019){

        yoad = "Your certicate is ready go to school portal";

      } else if (year == 2019){

        yoad = "Your certificate is in progress";

      } else {

        yoad = "cert not found";

      }

document.getElementById('cc').innerHTML=yoad

}

<h6>Enter your year of admission to know if your certificate is ready</h6>

<input id="age">

<button onclick="myfun()">enter</button>

<p id="xc"></p>

<p id="cc"></p>

  const year = parseInt(value);

  if (year > 2019) {

    yoad = "certicate not read";

  } else if (year >= 2014 && year <= 2019) {

    yoad = "Your certicate is ready go to school portal";

  } else {

    yoad = "cert not found";

  }

  

  document.getElementById('cc').innerHTML = yoad

}

<h6>Enter your year of admission to know if your certificate is ready</h6>

也許你需要這樣的東西！
