【jquery采坑】Ajax配合form的submit提交(微擎表单提交,ajax验证,submit提交)
1、采坑:实现form的submit提交,在提交之前,进行ajax的不同校验,然后onsubmit=return check(),进行提交
1/1 目的:可以实现以 from的submit提交,然后还能进行数据的ajax动态验证。
2、html:
<form class="form-horizontal" method="post" role="form" onsubmit='return check()'> <button type="submit" name="submit" id="submit_color" value="yes" >提交订单</button><br/> <input type="hidden" name="token" value="{$_W['token']}" /> <input type="hidden" name="source_from" value="午夜专区订购" /> <input type="hidden" name="can_buy" value="1" /> </div> </form>
3、js:
function check(){ var self=false; var delivery_date = $('input[name=delivery_date]').val(); var delivery_way=$('#dispatch option:selected').val(); ; var area_name = $("#area_span").html(); //配送方式需要区域限单判断 -- addBy xzz 2018/09/30 if(delivery_way=='4'||delivery_way=='8'){ $.ajax({ type: "POST", dataType: "JSON", async: false, //这里必须是同步,否则程序逻辑错误 url: "{php echo $this->createMobileUrl('checkself2',['op'=>'send_ajax_order_num_check'])}", data: {'delivery_date':delivery_date,'area_name':area_name}, success: function(msg){ console.log(msg); if(msg.error==0){ alert('抱歉!'+delivery_date+'日 配送量已经饱和,请选择自提'); self=true; }else{ return true; } } }); }else{ //自提不限 return true; } //配送库存是否满足限购,true不允许再下单,false允许下单 if(self){ return false; } }
