如何在此脚本中编写onChange?有人可以告诉我正确的语法吗?
我想将这些phpcode添加到我的脚本中
JavaScript代码:
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>
这是PHP代码:
<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>
最佳答案
使用单引号而不是双引号,并在引号之前添加反斜杠。
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);)"
