根据另一个下拉列表的值更改droplist的值 [英] Changing value of droplist based on the value of another dropdown list

问题描述

我需要根据下拉列表（1）的值更改下拉列表（2）中的选定值。我看了很多帖子但是找不到解决方案。

I need to change the selected value on a drop-down list(2) based on the value of the drop-down list(1). I had read a lot of posts but I can't find a solution.

下拉列表（1）

<select name="Active" id="Active" class="imaindatesel">
    <option value="" <?php if (!(strcmp("", $row_SeqUpdate['SeqActive']))) {echo "selected=\"selected\"";} ?>>Select........</option>
    <option value="1" <?php if (!(strcmp(1, $row_SeqUpdate['SeqActive']))) {echo "selected=\"selected\"";} ?>>Enabled</option>
    <option value="0" <?php if (!(strcmp(0, $row_SeqUpdate['SeqActive']))) {echo "selected=\"selected\"";} ?>>Disabled</option>   
</select>

下拉列表（2）

<select name="Client" class="imaindatesel" id="Client">
    <option value="" <?php if (!(strcmp("", $row_SeqUpdate['ClientName']))) {echo "selected=\"selected\"";} ?>>Select........</option>
    <option value="1" <?php if (!(strcmp(1, $row_SeqUpdate['ClientName']))) {echo "selected=\"selected\"";} ?>>Enabled</option>
    <option value="0" <?php if (!(strcmp(0, $row_SeqUpdate['ClientName']))) {echo "selected=\"selected\"";} ?>>Disabled</option>  
</select>

有没有办法用jQuery做这个？

Is there some way of doing this using jQuery?

非常感谢你的时间。

推荐答案

如下所示： -

$('#Active').on('change',function(){
   $('#Client').val($('#Active :selected').val());
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<select name="Active" id="Active" class="imaindatesel">
    <option value="">Select........</option>
    <option value="1">Enabled</option>
    <option value="0">Disabled</option>   
</select>


<select name="Client" class="imaindatesel" id="Client">
    <option value="">Select........</option>
    <option value="1">Enabled</option>
    <option value="0">Disabled</option>  
</select>
