從codeigniter到jsp的javascript

Question

我在codeigniter中有javascript方法，但是當我嘗試將它放入jsp時，javascript無法正常工作。在codeigniter中，如果我調用函數，頁面將刷新，但是當我嘗試將代碼放入我的jsp時，函數不會刷新頁面。

這樣的代碼：

<script type="text/javascript"> 
function submit_page(from){ 
    var doc = document.frm_data;   

    if(from == 1){ 
     doc.tipe_lst.value = ""; 
     doc.cab2_lst.value = ""; 
    }else{ 
     doc.wil_lst.value = ""; 
     doc.cab_lst.value = ""; 
    } 

    doc.action = "<?php echo $page_action;?>"; 
    doc.target=""; 
    doc.submit();       
} 

我把它從笨象這樣：

<form name="frm_data" method="post"> 

<div style="float:left; position:relative; width:350px;"> 
    <div> 
     <label>Kantor Wilayah : </label> 
     <select name="wil_lst" onchange="submit_page(1);"> 
      <option value=""></option> 
      <?php if(!empty($main_unit)){?>   
      <?php foreach($main_unit as $theitem): ?> 
      <option value="<?php echo $theitem->KDWIL;?>" <?php if($unit == $theitem->KDWIL) echo "selected";?>><?php echo $theitem->UNIT_BESARAN;?></option> 
       <?php endforeach; ?> 
      <?php } ?> 
     </select> 
    </div> 
    <div> 
     <label>Kantor Cabang : </label> 
     <select name="cab_lst" onchange="submit_page(1);"> 
      <option value=""></option> 
      <?php if(!empty($sub_unit)){?> 
      <?php foreach($sub_unit as $theitem): ?> 
      <option value="<?php echo $theitem->UNIT_BESARAN;?>" <?php if($subunit == $theitem->UNIT_BESARAN) echo "selected";?>><?php echo $theitem->UNIT_BESARAN;?></option> 
       <?php endforeach; ?> 
      <?php } ?> 
     </select> 
    </div> 
</div> 

<div style="float:left; position:relative; width:350px; padding-left:20px; border-left:1px solid;"> 
    <div> 
     <label>Tipe Cabang : </label> 
     <select name="tipe_lst" onchange="submit_page(2);" style="width:300px;"> 
      <option value=""></option> 
      <?php if(!empty($tipe_cabang)){?>   
      <?php foreach($tipe_cabang as $theitem): ?> 
      <option value="<?php echo $theitem->STATUS_CABANG;?>" <?php if($tipe == $theitem->STATUS_CABANG) echo "selected";?>><?php echo $theitem->STATUS_CABANG;?></option> 
       <?php endforeach; ?> 
      <?php } ?> 
     </select> 
    </div> 
    <div> 
     <label>Kantor Cabang : </label> 
     <select name="cab2_lst" onchange="submit_page(2);"> 
      <option value=""></option> 
      <?php if(!empty($sub_unit2)){?> 
      <?php foreach($sub_unit2 as $theitem): ?> 
      <option value="<?php echo $theitem->UNIT_BESARAN;?>" <?php if($subunit2 == $theitem->UNIT_BESARAN) echo "selected";?>><?php echo $theitem->UNIT_BESARAN;?></option> 
       <?php endforeach; ?> 
      <?php } ?> 
     </select> 
    </div> 
</div> 
<div class="clear"></div> 



</form> 

，當我試圖把它變成我的jsp，頁面沒有按」 t刷新或發送如下函數submit_page的動作：

<form name="frm_data" method="post"> 
    <div class="row"> 
     <form role="form"> 
     <div class="col-md-5 well bg-default"> 
      <div class="form-group"> 
       <label for="a">Kantor Wilayah</label><br/> 
       <select tabindex="1" name="tipe_lst" class="chosen-select" 
         style="width: 240px;" 
         onchange="submit_page(1);"> 
        <option value="">Pilih</option> 

        <c:if test="${not empty main_unit}"> 
         ${main_unit} 
        </c:if> 
       </select> 
      </div> 
      <div class="form-group"> 
       <select tabindex="1" name="cab_lst" onchange="submit_page(1);" 
         class="chosen-select" style="width: 350px;"> 
        <option value="">Pilih</option> 
        <option value="1">KANTOR CABANG BALIGE</option> 
        <option value="2">KANTOR CABANG UTAMA TANJUNG BALAI ASAHAN</option> 
       </select> 
      </div> 
     </div> 
     <div class="col-md-5 well bg-default"> 
      <div class="form-group"> 
       <label for="a">Tipe Cabang</label><br/> 
       <select tabindex="1" class="chosen-select" style="width: 240px;" name="a" id="a"> 
        <option value="">Pilih</option> 
        <option value="1">KANTOR WILAYAH MEDAN</option> 
        <option value="2">KANTOR WILAYAH PADANG</option> 
       </select> 
      </div> 
      <div class="form-group"> 
       <select tabindex="4" class="chosen-select" style="width: 350px;" name="d" id="d"> 
        <option value="">Pilih</option> 
        <option value="1">KANTOR CABANG BALIGE</option> 
        <option value="2">KANTOR CABANG UTAMA TANJUNG BALAI ASAHAN</option> 
       </select> 
      </div> 
     </div> 
     <div class="col-md-2 well bg-greensea"> 
      <div class="form-group"> 
       <label for="c">Pencarian Pegawai 
       <input type="text" class="form-control" id="input01"> 
       </label>       
      </div> 
      <div class="form-group"> 
      <button type="submit" class="btn btn-rounded btn-slategray btn-md">Search</button> 
      </div> 
     </div> 
     </form> 
    </div> 
</form> 

頁面不刷新。如何解決它？

我想你應該在Java腳本，而不是使用PHP JSP代碼

doc.action = "<?php echo $page_action;?>";
