onclick="this.src='{:U('Public/Verify')}&v='+Math.random()

public function Verify($value='')

{

$Verify = new \Think\Verify();

// $Verify->fontSize = 32;

$Verify->expire = 30;

$Verify->length? = 4;

$Verify->useCurve? = false;

$Verify->useNoise? = false;

// $Verify->imageW? =200;

$Verify->codeSet = '0123456789';

ob_clean();

$Verify->entry();

}

注意：到這就可以生成驗證碼了

1.入口文件不要有bom頭就是index.php開始部分不要有空格、輸出之類的

2.ob_clean();在生成之前用這個函數(shù)來丟棄緩沖區(qū) 否則有可能不顯示驗證碼
