JavaScript点击div来回切换两个颜色及两张图片切换的方法

点击div切换颜色的代码如下:

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Document</title>

<style>
    .test1{
        width:100px;
        height: 100px;
        background-color: green;
    }
</style>

<script type="text/javascript">
    function myFunction(){
        var test1 = document.getElementById('test1');
        if(test1.style.backgroundColor=='yellow'){
            test1.style.backgroundColor='green';
        }else{
            test1.style.backgroundColor='yellow';
        }
    }
</script>
</head>

<body>
    <div class="test1" id="test1" alt="" onclick="myFunction()">
    </div>
</body>
</html>

这里有一个疑问就是:如果js语句中颜色代码为十六进制则不显示效果。目前还没有解决这个问题 求大神指教QAQ

 

点击图片来回切换:

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title></title>
</head>
<body>

<script type="text/javascript">
    function toggle(){
        var test1 = document.getElementById('test1');
        if(test1.src.indexOf('on') >= 0){
            test1.src="./images/off.png";
        }else{
            test1.src="./images/on.png";
        }
    }
</script>

    <img id="test1" src="./images/on.png" alt="" onclick="toggle()" />
</body>
</html>
