类封装验证图如何输出+JS
这是用类封装的一个验证图 我的问题是如何在另外一个页面上调用它
- PHP code
<?phpclass ImageCode{ private $randcode; //随机字符 private $randcodelength; //随机字符长度 private $imgWidth; //随机字符宽度 private $imgHeight; //随机字符高度 private $line = 5; //干扰线 private $code = array("q","w","e","r","t","y","u","i","o","p","a","s","d","f","g","h","j","k","l","z","x","c","v","b","n","m", "Q","W","E","R","T","Y","U","I","O","P","A","S","D","F","G","H","J","K","L","Z","X","C","V","B","N","M", "1","2","3","4","5","6","7","8","9","0"); private $codelength; //数组的长度 private $image; //图片 private $background; //背景 private $foreground; //前景 function __construct(){ $this->randcodelength = 5; $this->imgWidth = 80; $this->imgHeight = 20; $this->codelength = count($this->code)-1; //获取数组长度当随机范围 $this->createrandcode(); $this->createimg(); $this->createString(); $this->drawline($this->line); $this->ending(); } function createrandcode(){ for($i=0;$i<$this->randcodelength;$i++){ //初始化验证码 $this->randcode .= $this->code[rand(0,$this->codelength)]; } } function createimg(){ //创建图片 前景 背景颜色 $this->image = imagecreatetruecolor($this->imgWidth,$this->imgHeight); $this->background = imagecolorallocate($this->image,0,0,0); $this->foreground = imagecolorallocate($this->image,255,255,255); } function createString(){ //创建字符串 imagestring($this->image,5,rand(5,35),0,$this->randcode,$this->foreground); } function drawline($some){ for($i=0;$i<$some;$i++){ imageline($this->image,rand(1,$this->imgWidth),rand(1,$this->imgHeight),rand(1,$this->imgWidth),rand(1,$this->imgHeight),$this->foreground); } } function ending(){ ob_clean(); //抛弃缓存内容 header("Content-type: image/jpeg"); imagejpeg($this->image); }}?>下面是输出页面
- PHP code
<?phpinclude("ImageCode.php");$imgcode = new ImageCode();?><!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">

<meta http-equiv="Content-Type" content="text/html; charset=gb2312" />
<title>无标题文档</title>
<script type="text/javascript">
function RefreshCode(){
alert("HelloWorld");
}
</script>
</head>
<body>
<img src="ImageCode.php" onclick="RefreshCode()"/>
</body>
</html>
这里我不知道怎么写 因为貌似是靠new ImageCode();来输出的验证图 而且不管怎么写 点击那个图片也没关联到show方法alert()也不出来
请高人指教
[解决办法]
<img src="ImageCodeServer.php?mr=112" onclick="RefreshCode(this)"/>
在路劲ImageCodeServer.php?后价格随机数,当相应点击事件时在改变这个src连接地址的随机数就可以实现点击切换验证码了!
在ImageCodeServer.php
这个文件中就应经画好了验证码了
