我有一个选择输入,从数据库retailer_id获取选项,我需要它,当管理员在此选择输入上选择零售商时,我将使用retailer_slug新的,然后,当管理员创建或更新,将数据库中的retailer_id和零售商插件隐藏在输入上。我的代码是:

<select class="textbox2" id="retailer_id" name="retailer_id">
<option value="">--- Please select store ---</option>
<?php
$sql_retailers = smart_mysql_query("SELECT * FROM cashbackengine_retailers WHERE status='active' ORDER BY title ASC");
while ($row_retailers = mysql_fetch_array($sql_retailers))
{
if ($retailer_id == $row_retailers['retailer_id']) $selected = " selected=\"selected\""; else $selected = "";
echo "<option data-slug=\"".$row_retailers['slug_title']."\" value=\"".$row_retailers['retailer_id']."\"".$selected.">".$row_retailers['title']."</option>";
}
?>
</select>
<input type="text" name="slug" id="slug" value=""/>
<script type="text/javascript">
$(document).ready(function() {
$('#retailer_id').on('change', function() {
var $selected = $('#retailer_id option:selected');
$('input[name=slug]').val($selected.data('slug'));
});
});
</script>
推荐答案
如果我理解正确,这是你可以做的一件事执行:
If I understand correctly, this is one thing you could do:
PHP
<select class="textbox2" id="retailer_id" name="retailer_id">
<option value="">--- Please select store ---</option>
<?php
$sql_retailers = smart_mysql_query("SELECT * FROM cashbackengine_retailers WHERE status='active' ORDER BY title ASC");
while ($row_retailers = mysql_fetch_array($sql_retailers))
{
if ($retailer_id == $row_retailers['retailer_id']) $selected = " selected=\"selected\""; else $selected = "";
echo "<option data-slug=\"".$row_retailers['retail_slug']."\" value=\"".$row_retailers['retailer_id']."\"".$selected.">".$row_retailers['title']."</option>";
}
?>
</select>
<input type="hidden" name="retailer_slug"/>
jQuery
$('#retailer_id').on('change', function() {
var $selected = $('#retailer_id option:selected');
$('input[name=retailer_slug]').val($selected.data('slug'));
});
所以基本上,这里的想法是保存 retailer_slug
每个<选项>
上的数据 -
属性值。然后,当更改所选选项时, retailer_slug
值将复制到隐藏输入。
So basically, the idea here is that you save the retailer_slug
value as a data-
attribute on each <option>
. Then when the selected option is changed, the retailer_slug
value is copied over to the hidden input.
