我有一个page1.php，我有一个fly.php。page1.php是一个简单的（常规）表单页面，当用户提交表单时，人们会在其中放置信息。

• 通过ajax，它加载验证码模板，并要求即时验证（直到这里很好）。
• 经过onFly验证后，我要允许此.submit（）继续

问题：How can i after .submit() pause for validatio此验证码中的n个，并在验证成功之后，恢复表单提交（处于保留状态）？

例：

第1部分：page1.php

$(document).ready(function()
{
 $('.callmeback').submit(function()
 {
    $.ajax({
        type    : "GET",
        url     : "/include/class/fly.php",
        data    : "a=b",
        async   : false,
        beforeSend: function()
        {
            $(document.body).find('.blackwindow').remove();
            $(document.body).find('.nospam').remove();  
        },  
        complete: function()
        {
        },      
        success : function(msg)
        {
           $(document.body).append(msg);
           $('.blackwindow').css({
              'opacity':'0.90'
           });

           $('.nospam').find('input[type="button"]').live("click", function()
           {
              // final validation
              var security= $('.nospam').find('#security').val();
              var random  = $('.nospam').find('#random').val();

                  if (random!=security)
              { 
            alert ('Invalid captcha.');
            return false;

               } else  {
            // Basically its second time? and return true?                      
               }

           });

        }

    });

    //return false;
 });

});

<form method=post action=thanks.php class="callmeback">
<input type=text value=100.00 name=amount />
<input type=submit value=submit name=submit />
</form>

第2部分：fly.php

<? require_once 'obj.php';?>
.blackwindow {
        position:fixed;
        top:0px;
        left:0px;
        width:100%;
        height:100%;
        z-index:1000;

        background-color:#000000;
}

.nospam {
        position:fixed;
        top:30%;
        left:30%;
        padding:12px;
        border:solid 3px #686868;
        background-color:#ffffff;
        z-index:1001;
}
<div class="blackwindow"></div>
<div class="nospam">
<div>
<?
$value = obj::getRandom();                                          
echo '<img src="include/class/return_img.php?number=' . $value . '" />';
echo "<input type='hidden' id='random' name='random' value='$value' />";
?>     
<div>
*Please enter the above code below, to verify this request <br/>
<input type="text" class="textbox" id="security" name="security" />
</div>
</div>
<div>
<input type=button name=mybutton value="Verify" />
</div>
</div>
