javascript - 颜色更改按钮不起作用

Question

<script language="javascript" type="text/javascript" src"change.js"></script>
    <form>
    <input type="button" name="Button1" value="RED" onclick="changecolor('red')">
    <input type="button" name="Button1" value="BLUE" onclick="changecolor('blue')">
    <input type="button" name="Button1" value="Green" onclick="changecolor('green')">
    <input type="button" name="Button1" value="Yellow" onclick="changecolor('yellow')">
    </form>

This code is saved as change.js

function changecolor(code) {
    document.bgColor=code
}

颜色更改按钮出现但不起作用。

Answer 1

src"change.js" 缺少 = 符号。应该是 src="change.js"
