我想我已经接近正确了,但是我不知道当用户盘旋在它上面时,如何改变我提交按钮的颜色,我也是非常新的javascript,所以任何帮助都会非常感谢。
这是我的代码:
<html>
<head>
<title>JavaScript</title>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<script>
function getName(){
var name;
name = window.prompt("Enter your name", "");
greeting = "User Information for " + name;
var txt= document.getElementById('txtWelcome');
txt.innerHTML=greeting;
}
function over() {
document.getElementById("Submit").style.background = 'Blue';
}
function out() {
document.getElementById("Submit").style.background = 'Yellow';
}
</script>
</head>
<body onload="getName()">
<form class="basic_form">
<h1 id="txtWelcome"></h1>
<p>Please input your login details</p>
<fieldset>
<label class="form_labels">Username:</label>
<input class="form_fields" type="text" name="username"><br>
<label class="form_labels">E-Mail:</label>
<input class="form_fields" type="email" name="email"><br>
<label class="form_labels">Password:</label>
<input class="form_fields" type="password" name="password">
<input class="form_buttons" type="Submit" value="Submit"><br>
</fieldset>
</form>
</body>

以下是javascript解决方案:
var submitButton = document.getElementById('submit');
submitButton.addEventListener('mouseover', function() {
this.style.backgroundColor='blue';
});
submitButton.addEventListener('mouseout', function() {
this.style.backgroundColor='yellow';
});

但是为什么不直接使用css呢?
input[type=submit]:hover {
background-color: red;
}
