我想将此代码(下拉选择课程)更改为预先输入,所以我只需要输入几个单词,然后它会提示。

<TD width="112"><INPUT type="checkbox" name="chk[]"/></TD>
        <TD width="472">
            <SELECT name="course[]">
                <?php
                  $sql = "select * from tt_course";
                  $result = mysql_query($sql);
                  while($rs = mysql_fetch_assoc($result))
                    {
                        $select="";
                        echo "<option value=\"".$rs['course_id']."\" ".$select.">".$rs['course_name']."</option>";
                    }
                  ?>
            </SELECT>
        </TD>

看看http://jqueryui.com/demos/autocomplete/ 它的设置简单易行,可以达到目的。您可以创建一个值数组并将其提供给 Autocomplete,或者您可以让它调用您的 php 页面并解析返回的 JSON 数据。

正如所承诺的,这里有一个示例代码可以帮助您进行操作。请注意,此代码使用本地 javascript 变量为自动完成框准备建议。您可以轻松地更新它以从您的 php 页面中查找 JSON 数据,我可以轻松地让您做到这一点,但目的是帮助您学习,所以我认为这样对您来说会更好,这样您就可以看到它是如何工作的,并且然后根据您的需要进行相应更新。在这里,您可以简单地复制粘贴此代码并查看它运行
