Question

我正在使用php和html创建一个网站，其中包含一些功能。目前我使用.change和.load事件进行各种提取和显示。我用过

$("#jobtable").load("editjob.php?jobchose=" + $("#jobnoselect").val());

提交并显示php结果，这是一个表单。但是当我在表单中点击提交时它什么也没做（我可以看到！）。

表单提交的结果应显示“完成！”

在Job Select上执行的代码是

$dbhandle = mysql_connect($hostname, $username, $password) or die("Unable to connect to MySQL");
$selected = mysql_select_db("a9629416_btstats", $dbhandle) or die("Could not select examples");
$jobchose = mysql_real_escape_string($_GET['jobchose']);

$query = "SELECT * FROM MasterJobTable WHERE JobNo='$jobchose'";

$result = mysql_query($query);
    $result2 = mysql_query($query);
    $current = mysql_fetch_array($result2);

    echo "<table>";
    echo "<tr>";
    echo "<td colspan=\"13\">Current: <h7>" . $current['JobNo'] . "</h7></td>";
    echo "</tr>";
    echo "<tr>";
    echo    "<td>NI7S</td>
            <td>NI7W</td>
            <td>NI7F</td>
            <td>NI1V</td>

    echo "</tr>";

doeditjob.php的代码只是echo "Done!";

您在加载功能中发送了错误的内容。变化：

$("#jobnoselect").change(function() 
{
   $("#jobtable").load("editjob.php?jobchose=" + $("#jobnoselect").html());
});

到此：

$("#jobnoselect").change(function() 
{
   $("#jobtable").load("editjob.php?jobchose=" + $("#jobnoselect").val());
});

注意.html()和.val()

的区别

当您执行第一个时，您会收到以下javascript错误（请查看您的控制台）

Uncaught Error: Syntax error, unrecognized expression: <option>Please Select Job Number</option><option>fghdfghdfghfg</option><option>fdshsgfh</option><option>gjdfgj</option><option>dfhs</option><option>cfbdfgdfg</option>

修改：您的选择也没有值。这是他们呈现的方式：

    <select id="jobnoselect">    
   <option>Please Select Job Number</option>
    <option>jhkushd</option>
    <option>uiuikuyi</option>
    <option>test</option></select>

我认为问题的一部分是你的HTML标记。尝试在表格外面添加表单标签，然后再将其清理一遍，然后再试一次

无法提交表格
