问题描述
在这里寻找一些改进我的编码的建议。
你如何使这段代码更短/更高效?
var resultsConstructionYear = readCookie('constructionYear');
if (resultsConstructionYear == 3) {
document.getElementById('resultsUserConstructionYear').innerHTML = "Avant 1944";
} else if (resultsConstructionYear == 4) {
document.getElementById('resultsUserConstructionYear').innerHTML = "Entre 1945 et 1974";
} else if (resultsConstructionYear == 5) {
document.getElementById('resultsUserConstructionYear').innerHTML = "Entre 1975 et 1989";
} else if (resultsConstructionYear == 6) {
document.getElementById('resultsUserConstructionYear').innerHTML = "Entre 1990 et 2009";
} else if (resultsConstructionYear == 7) {
document.getElementById('resultsUserConstructionYear').innerHTML = "Après 2010";
} else {
document.getElementById('resultsUserConstructionYear').innerHTML = "Inconnue";
}
解决方法
按施工年份编号创建一个对象或一个文本地图。如果对象上不存在数字,则使用 'Inconnue'
作为后备:
const textByNumber = {
3: 'Avant 1944',4: 'Entre 1945 et 1974',5: 'Entre 1975 et 1989',...
};
const resultsConstructionYear = readCookie('constructionYear');
document.getElementById('resultsUserConstructionYear')
.innerHTML = textByNumber[resultsConstructionYear] || 'Inconnue';
,
你可以试试这个代码。
let resultsConstructionYear = readCookie('constructionYear');
let response = null;
switch(resultsConstructionYear) {
case 3:
response = 'Avant 1944';
break;
case 4:
response = 'Entre 1945 et 1974';
break;
case 5:
response = 'Entre 1975 et 1989';
break;
case 6:
response = 'Entre 1990 et 2009';
break;
case 7:
response = 'Après 2010';
break;
default:
response = 'Inconnue';
}
document.getElementById('resultsUserConstructionYear').innerHTML = response;
