img onclick 函数
Img onclick function
我的图片很少,点击后,我想 运行 编码,比如提醒图片编号。
<img onclick="picture(1)" src="asd.jpg">
<img onclick="picture(2)" src="sdf.jpg">
<script>
function picture(picnumber){
alert(picnumber);
}
</script>
当我警告字符串而不是变量时,它起作用了。
编辑:很抱歉包含示例而不是我的实际代码,我认为没问题,下面给出的解决方案没有修复我的代码:
<body>
<style>
img{
height:80px;
}
</style>
<script>
function picture(picbumber){
alert(picnumber);
}
</script>
<h1>GALLERY</h1>
<div class="photos">

只是改变顺序,在onclick中你正在执行一个尚未定义的函数否则
<script>
function picture(picnumber){
alert(picnumber);
}
</script>
<img onclick="picture(1)" src="asd.jpg">
<img onclick="picture(2)" src="sdf.jpg">
请在头部添加脚本代码。在这里查看我的演示。
<head>
<script>
function picture(picnumber){
alert(picnumber)
}
</script>
</head>
<body>
<img onclick="picture(1)" src="./asd.jpg" />
<img onclick="picture(2)" src="./sdf.jpg" />
</body>
</html>```
