需要引入的js文件
<script type="text/javascript" src="__PUBLIC__/js/jquery.js"></script>
<script type="text/javascript" src="__PUBLIC__/js/jquery.form.js"></script>
<script type="text/javascript" src="__PUBLIC__/js/artdialog/jquery.artDialog.js?skin={$Think.config.ART_DIALOG.skin}"></script><script type="text/javascript">
$(function(){
//向客户端ajax发送数据
$("#verify:text").blur(function(){
var verify = $(‘#verify‘).val();
var data = ‘verify=‘ +verify;
$.ajax({
type: "post",
datatype:"json",
url: "__URL__/verify",
data: data,
success: function(data){
if(data==‘false‘){
$("form").submit(function(e){
e.preventDefault();
});
}else{
GetMoreSource()
//document.getElementById(‘submit‘).submit()="false";
}
},
error: function() { alert("error"); } ,
});
});
});
function GetMoreSource() {
data=$(‘.calculate‘).serialize();
$.ajax({
type: "post",
datatype:"json",
url: "__URL__/matchAdviserList",
data: data,
success: function(data){
$("#divok").html(data);
},
error: function() { alert("error"); } ,
});
}php验证部分代码
//判断验证码是否正确
public function verify(){
$verify=$this->_post(‘verify‘);
if($_SESSION[‘verify‘]==md5($verify)&&!empty($verify)){
echo ‘true‘;
}else{
echo ‘false‘;
}
}html部分实现代码
<body> <form action="" method="post" id="submitForAjax" > aaa:<select name="webtype" class="calculate"> <option value="" selected></option> </select><br> bbb :<input type="text" name="dayPv" class="calculate"><br> ccc:<input type="text" name="indexPage" class="calculate"><br> ddd:<input type="text" name="dataCon" class="calculate"><br> eee:<input type="text" name="verify" nullmsg="请输入验证码" id="verify"><span id="result"></span> <a href="#"><img id="im" src="__APP__/User/Login/verify" onclick="this.src=‘__APP__/User/Login/verify/?id=‘+Math.random()*5;" /></a> <i><a href="#" title="换一张" onclick="document.getElementById(‘im‘).src=‘__APP__/User/Login/verify/?id=‘+Math.random()*5;">换一张</a></i> </form> <input type="submit" value="按钮" id="submit" > <div id="divok"> </div> </body>使用了异步验证
jquery，Ajax判断验证码是否正确，不正确阻止提交,布布扣,bubuko.com
