Javascript 运行函数combobox为多个combobox填充的jQuery

我有组合框

 <select name="search_category[]"  id="search_category_id">
    <option value="" selected="selected"></option>
    <?php
    $query = "SELECT * FROM t_category ORDER BY category_name ASC";
    $results = mysql_query($query);

    while ($rows = mysql_fetch_assoc(@$results))
    {?>
        <option value="<?php echo $rows['category_id'];?>"><?php echo $rows['category_name'];?></option>
    <?php
    }?>
</select>

<span id="show_sub_categories" align="center">

如果我有多个不同id的组合框如何

例如：

<select name="search_category[]"  id="search_category_id1">
    <option value="" selected="selected"></option>
    <?php
    $query = "SELECT * FROM t_category ORDER BY category_name ASC";
    $results = mysql_query($query);

    while ($rows = mysql_fetch_assoc(@$results))
    {?>
        <option value="<?php echo $rows['category_id'];?>"><?php echo $rows['category_name'];?></option>
    <?php
    }?>
</select>

<select name="search_category[]"  id="search_category_id2">
    <option value="" selected="selected"></option>
    <?php
    $query = "SELECT * FROM t_category ORDER BY category_name ASC";
    $results = mysql_query($query);

    while ($rows = mysql_fetch_assoc(@$results))
    {?>
        <option value="<?php echo $rows['category_id'];?>"><?php echo $rows['category_name'];?></option>
    <?php
    }?>
</select>

我想要为2组合框运行函数。但是当尝试运行代码时，该函数只针对第一个combobox运行。（该函数基于第一个组合框填充第二个组合框）。

您需要在

$.post.success

处理程序中加载第二个

选择

。示例（未测试）：

<select name="search_category[]"  id="search_category_id1">
    <option value="" selected="selected"></option>
    <?php
    $query = "SELECT * FROM t_category ORDER BY category_name ASC";
    $results = mysql_query($query);

    while ($rows = mysql_fetch_assoc(@$results))
    {?>
        <option value="<?php echo $rows['category_id'];?>"><?php echo $rows['category_name'];?></option>
    <?php
    }?>
</select>

<select name="search_category[]"  id="search_category_id2">
    <option value="" selected="selected"></option>
    <?php
    $query = "SELECT * FROM t_category ORDER BY category_name ASC";
    $results = mysql_query($query);

    while ($rows = mysql_fetch_assoc(@$results))
    {?>
        <option value="<?php echo $rows['category_id'];?>"><?php echo $rows['category_name'];?></option>
    <?php
    }?>
</select>

$.post("get_chid_categories.php", 
    { parent_id: $('#search_category_id1').val() },
    function (response){
        loadSelect("search_category_id2", response);
    }
);

function loadSelect(id, response){
    $('#loader').hide();
    $('#show_heading').show();

    var target = $('#' + id);
    target.html(decodeURIComponent(response));
    if (!target.is(":visible")) {
        target.fadeIn();
    }
}
