只需使用并操作它會幫助您檢查 2 個條件

function myfun(){

//var yofad = document.getElementById('age').value;

var yoad;

var year = 2014 ;

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

}

將您的第一個條件限制為小于 2019，否則對于 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>

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

function myfun(){

document.getElementById('cc').innerHTML = "";

const value = document.getElementById('age').value;

if (!value) return;

const year = parseInt(value);

let yoad;

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>

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

也許你需要這樣的東西！
