为什么同样的提交代码，在不同页面获取的就是不同的提交地址。

我直接在/index.php?s=qyfw&c=category&id=3

这个页面 用浮窗形式，然后填写表单以后，提示的 系统错误。但是没有生成日志。

然后我又在/index.php?s=form&c=yyqyzx&m=post

同样也提交了一次，结果可以提交成功。

于是我检查了下源代码。发现提交的地址不对劲。

这个是在/index.php?s=qyfw&c=category&id=3 的

下面这个是在/index.php?s=form&c=yyqyzx&m=post

这个页面提交的，这种就可以提交成功

我的提交代码是：

<!--弹出层-->
<div id="div_dj" style="display: none">
{php extract(dr_get_form_post_value('yyqyzx'))}
	<form action="" class="form-horizontal" method="post" name="myform" id="myform">
    {$form}
  <h3 class="center">在线预约面谈</h3>
    <div class="line-dot top10 bottom20"></div>
    <div class="fc-form-body">
        {$myfield}
        {$diyfield}
        {$sysfield}
        {if $is_post_code}
        <div class="form-group">
            <label class="control-label col-md-2">{dr_lang('验证码')}</label>
            <div class="col-md-9">
                <label>
                    <div class="form-recaptcha">
                        <div class="input-group">
                            <input type="text" class="form-control" name="code">
                            <div class="input-group-btn fc-code">
                                {dr_code(120, 35)}
                            </div>
                        </div>
                    </div>
                </label>
            </div>
        </div>
        {/if}
    </div>
    <div class="portlet-body form myfooter">
        <div class="form-actions text-center">
                                        <button type="button" onclick="dr_ajax_submit('{dr_now_url()}', 'myform', '2000', '{$rt_url}')" class="btn green"> <i class="fa fa-save"></i> 提交内容</button>
            
        </div>
    </div>
</form>
</div>
<script language="javascript">
 function show_dj(){
	 layer.open({
			  type: 1, 
        title: false,
     closeBtn: 1,
         area: ['auto'],
   shadeClose: true,
      content: $("#div_dj"),
			}); 
 }	
</script>

                        独立页面提交的代码
                        
                          <form action="" class="form-horizontal" method="post" name="myform" id="myform">
                                {$form}
                                <div class="fc-form-body">
                                    {$myfield}
                                    {$diyfield}
                                    {$sysfield}
                                    {if $is_post_code}
                                    <div class="form-group">
                                        <label class="control-label col-md-2">{dr_lang('验证码')}</label>
                                        <div class="col-md-9">
                                            <label>
                                                <div class="form-recaptcha">
                                                    <div class="input-group">
                                                        <input type="text" class="form-control" name="code">
                                                        <div class="input-group-btn fc-code">
                                                            {dr_code(120, 35)}
                                                        </div>
                                                    </div>
                                                </div>
                                            </label>
                                        </div>
                                    </div>
                                    {/if}
                                </div>

                                <div class="portlet-body form myfooter">
                                    <div class="form-actions text-center">
                                        <button type="button" onclick="dr_ajax_submit('{dr_now_url()}', 'myform', '2000', '{$rt_url}')" class="btn green"> <i class="fa fa-save"></i> 提交内容</button>
                                    </div>
                                </div>
                            </form>

这种是什么原因呢。
