如何在DW中加入登陆验证码

Answer 1

最简单的就是用JS判断 如: <script language="javascript"> function verify(){ yzm=document.frm2.yzm; txt=document.frm2.txt; if(yzm.value!=txt.value){ alert("验证码不正确！"); yzm.select(); } } function yzmview(){ document.frm2.txt.value=Math.floor(Math.random()*8999)+1000; } </script> <form action="" method="post" name="frm2" id="frm2" onsubmit="return verify()"> 验证码<input name="yzm" type="text" id="yzm" size="7" value="点击获取" maxlength="6" onfocus="yzmview();this.value=''" />   <input name="txt" type="text" id="txt" size="5" readonly="readonly" style="color:#C00;font-weight:bold;border:0px" /> </form>
