我想知道你们中是否有人能帮助我，告诉我为什么我的代码不起作用。我想做的是，当我按下EN按钮时，语言将更改为英语，当我按ES按钮时，语文将更改为西班牙语。问题是我编写的javascript代码不起作用。
const english = document.getElementById("en")
const espanol = document.getElementById("es")
const hey = document.getElementById("hey")
const text = document.getElementById("text")
english.addEventListener("click", function() {
change(english, espanol);
});
espanol.addEventListener("click", function() {
change(espanol, english);
});
function change(lang1, lang2) {
if (lang1.innerHTML == "EN") {
hey.innerHTML = "Hey, I'm English";
text.innerHTML = "I am a text in the English language";
} else {
hey.innerHTML = "Hey, yo soy Español";
text.innerHTML = "Yo soy un texto en el idioma ingles ";
}

您可以在输入字段上使用change事件，而不是
const english = document.getElementById("en")
const espanol = document.getElementById("es")
const projects = document.getElementById("hey")
const contact = document.getElementById("text")
const toggle = document.getElementById("language-toggle")
toggle.addEventListener("change", function(e) {
if (e.target.checked) {
change(espanol, english);
} else {
change(english, espanol);
}
})
function change(lang1, lang2) {
if (lang1.innerHTML == "EN") {
hey.innerHTML = "Hey, I'm English";
text.innerHTML = "I am a text in the English language";
} else {
hey.innerHTML = "Hey, yo soy Español";
text.innerHTML = "Yo soy un texto en el idioma ingles ";
}
}.switch {
position: relative;
display: inline-block;
