如何在這個腳本中寫onChange ??誰能告訴我正確的語法? 我想這些phpcode添加到我的劇本 Javascript代碼:如何在這個腳本中寫onChange ??誰能告訴我正確的語法

ih+='<div class="form-group drop_bottom" id="select_one_'+extra_num+'"><select name="sizes_'+extra_num+'" style="position:absolute;top:0px;left:0px;width:200px; height:25px;line-height:20px;margin:0;padding:0;" id="sizes_'+extra_num+'" onChange="+document.getElementById("displayValue").value=this.options[this.selectedIndex].text;+document.getElementById("sizes_'+extra_num+'").value=this.options[this.selectedIndex].value;this_total(this,1);grand_total(this)"><option value="0">Select One</option> 

這裏是PHP代碼:

<div style="position:relative;width:200px;height:25px;border:0;padding:0;margin:0;" id="select_one_0" class="form-group drop_bottom"> 

    <select name="sizes_0" id="sizes_0" style="position:absolute;top:0px;left:0px;width:200px; height:25px;line-height:20px;margin:0;padding:0;" onChange="document.getElementById('displayValue').value=this.options[this.selectedIndex].text; document.getElementById('select_sizes_0').value=this.options[this.selectedIndex].value;this_total(this,1);grand_total(this)" >  <option value="0" >Select One</option> 
      <?php 
    $get_banner_tyes = Get_banner_tyes(); 
      if($get_banner_tyes != false) 
      { while($row_get_banner_tyes = mysql_fetch_array($get_banner_tyes)) 
       { 
      ?> 
      <option value="<?php echo $row_get_banner_tyes['banner_type_value'] * $_SESSION['secondary_currency_value']; ?>_<?php echo $row_get_banner_tyes['banner_type_id']; ?>"><?php echo $row_get_banner_tyes['banner_type_name']; ?></option> 

      <?php } ?> 
       <?php } 
      ?>   

        </select> 
    <input name="displayValue" placeholder="Width*Height value" id="displayValue" style="position:absolute;top:0px;left:0px;width:183px;width:180px\9;#width:180px;height:23px; height:21px\9;#height:18px;border:1px solid #556;" onFocus="this.select()" type="text"> 
<input name="idValue" id="select_sizes_0" type="hidden" > 
     <input type="hidden" name="select_sizes_0" id="select_sizes_0"> 
    <input type="hidden" name="select_elements_0" id="select_elements_0"></div>

您應該編寫函數以遵循最佳實踐。並調用該函數。 –

+0

onchange函數沒有得到這個腳本。我認爲我的語法不正確 – sypr

使用單引號,而不是雙引號和引號前添加反斜線。

onChange="(document.getElementById(\'displayValue\').value=this.options[this.selectedIndex].text; document.getElementById(\'sizes_'+extra_num+'\').value=this.options[this.selectedIndex].value;this_total(this,1);grand_total(this);)"
