Javascript 更改组合框时，将生成具有自定义ID的Div容器

很抱歉，我正在深入研究PHP、Javascript和HTML编码，可能需要一些帮助

我希望使用一个组合框，根据用户选择为我的表单生成Div容器

因此，如果选择了3，则通过循环处理一个预制容器，以迭代给定框和div容器本身的html id。一旦这些生成的div值完成，我想将其发送到邮件处理页面

我正在使用JQuery、PHP和HTMl标记作为语言

这是将生成Div容器的选择框：

<select id="move_num" name="Move_Number">
   <option value="" selected="selected">0</Option>
   <option value="1">1</option>
   <option value="2">2</option>
   <option value="3">3</option>
   <option value="4">4</option>
   <option value="5">5</option>
   <option value="6">6</option>
   <option value="7">7</option>
   <option value="8">8</option>
   <option value="9">9</option>
   <option value="10">10</option>
   <option value="11">11</option>
   <option value="12">12</option>
   <option value="13">13</option>
   <option value="14">14</option>
   <option value="15">15</option>
</select>

以下是生成容器Div的PHP代码：

<div id="target">
<?php
$num = $_GET['move_num'];
for ($i = 1; $i < $num; $i++) {
echo "<div class='box'>";
echo "<span class='titleHeaders'>Person ".$i." Information</span>";
echo "        <table>";
echo "            <tr>";
echo "              <td width='5%'>";
echo "              <img src='../images/questionmark.png' height='20' width='20' title=''>";
echo "                </td>";
echo "                <td><label id='Move_Name".$i."' for='Move_Name".$i."'>Employee Name: </label></td>";

我需要一个改变的触发器，我现在正在努力。此外，PHP语句中的for循环出现了一些我似乎无法识别的错误。

将%I替换为for循环中的$I..$num=$\u GET['move\u num'].val；这是什么？这是通过ID提取SELECT元素的值并获取值。在PHP中不需要.val来获取值$num=$\u GET['move\u num']；你应该使用jQueryAjax来完成这项工作。读这个
