我只是在试验和制作一个小游戏，但在此之前，我为用户制作了按钮来选择角色，当他们将鼠标悬停在角色上时，他们会看到关于它的简介，我是一个新的编码人员，所以不知道innerhtml的概念，但我使用ws3schools来使用它，但它仍然没有工作
我尝试使用innerhtml，但文本不显示这里是html的代码:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<link rel="stylesheet" href="styles.css">
<script src="main.js"></script>
<title>Tomoko Game</title>
</head>
<body>
<h1 class="header">Choose your Tomoko </h1>
<button onclick="NewPagePo()" onfocus="AddPo()" form="ReButton" id = "ButtonRehanPo">Tomoko Polite <img id="TomoPicL" src="C:UsersRehan Muhammad Ali.vscodeTomokoPhotos20221109_054642.jpg" alt="Dog"></button>
<button onclick="NewPageDa()" onfocus="AddDa()" form="ReButton" id = "ButtonRehanDa">Tomoko Dangerous <img id="TomoPicR" src="C:UsersRehan Muhammad Ali.vscodeTomokoPhotosCIMG0093.JPG" alt="Dog"></button>
<button onclick="NewPageAll()" onfocus="AddAll()" form="ReButton" id = "ButtonRehanAll">Tomoko All-Rounder <img id="TomoPicM" src="C:UsersRehan Muhammad Ali.vscodeTomokoPhotos20211214_192451.jpg" alt="Dog"></button>
<p id="p1">Hi</p>
</body>
</html>
按钮上的显示得到焦点="AddAll()";这是一个js函数，我在这里输入了文本
function NewPagePo() {
open("indexPo.html", "_self");
}
function NewPageAll() {
open("indexAll.html", "_self");
}
function NewPageDa() {
open("indexDa.html", "_self");
}
function Back() {
open("index.html", "_self");
}
function AddAll() {
document.getElementById("ButtonRehanAll").innerHTML = "Test1";
}
基本上就是这样。如果你想回顾一下CSS，看看它是否可以改进，我洗耳恭听css:
