Question

我正在尝试从隐藏的输入传递一些POST变量（使用JQuery根据td字段中的文本更改输入的值）。我已经测试了JQuery，它确实为输入分配了正确的值，但是当我尝试根据上一页的值分配POST变量时，它们没有设置为数字。

代码：

<form method="POST" action="newcriminalreport2.php">

            <div style="width:800px;text-align:left;margin:0 auto;padding-bottom:5px;">A. PENDING BALANCE</div>
            <table border="1" style="width:800px;" ID="tableA">
            <th style="width:40%;"></th>
            <th colspan="2" style="width:20%;">CAPITAL</th>
            <th colspan="2" style="width:20%;">NON-CAPITAL</th>
            <th colspan="2" style="width:20%;">TOTAL</th>
            <tr>
            <td></td>
            <td>Defs</td>
            <td>Cases</td>
            <td>Defs</td>
            <td>Cases</td>
            <td>Defs</td>
            <td>Cases</td>
            </tr>
            <tr>
            <td>1. Pending Balance from Previous Month</td>
            <td id="PendingCapDefs">123</td><input type="hidden" name="PendingCapDefs" id="PendingCapDefsInput">
            <td id="PendingCapCases">2</td><input type="hidden" name="PendingCapCases" id="PendingCapCasesInput" value="">
            <td id="PendingNonCapDefs">3</td><input type="hidden" name="PendingNonCapDefs" id="PendingNonCapDefsInput" value="">

            <td id="PendingDefsTotal">5</td><input type="hidden" name="PendingDefsTotal" id="PendingDefsTotalInput" value="">
            <td id="PendingCasesTotal">6</td><input type="hidden" name="PendingCasesTotal" id="PendingCasesTotalInput" value="">
            </tr>
            </table> 

            <br/><br/><div style="width:800px;text-align:left;margin:0 auto;padding-bottom:5px;">B. CRIMINAL CASE ASSIGNMENTS</div>

            <th colspan="2" style="width:20%;">CAPITAL</th>
            <th colspan="2" style="width:20%;">NON-CAPITAL</th>
            <th colspan="2" style="width:20%;">TOTAL</th>
            <tr>
            <td></td>
            <td>Defs</td>
            <td>Cases</td>

            <td>Cases</td>
            <td>Defs</td>
            <td>Cases</td>
            </tr>
            <tr>

            <td id="AsgNewTotalDefs">234</td>
            <td id="AsgNewTotalCases">345</td>
            </tr>
            <tr>
            <td>3. Transfers Received</td>
            <td><input type="text" name="username" size="5" id="AsgTRCapDefs"/></td>

            <td id="AsgRCTotalCases">345</td>
            </tr>
            <tr>
            <td>5. Total Cases Assigned</td>
            <td id="PendingCapDefsTotal"/>0</td><input type="hidden" name="PendingCapDefsTotal" id="PendingCapDefsTotalInput" value="">

            <td id="PendingTotalDefs">0</td><input type="hidden" name="PendingTotalDefs" id="PendingTotalDefsInput" value="">
            <td id="PendingTotalCases">0</td><input type="hidden" name="PendingTotalCases" id="PendingTotalCasesInput" value="">
            </tr>
            </table> 

        <br />
        <div style="text-align:right; width: 900px;"><input type="submit" value="Save and Continue -->" style="border:none;background-color:transparent;color:blue;text-decoration:underline"></form>

和下一页：

<?php
    session_start();
    $judge = $_SESSION['judge'];
    if(!isset($_SESSION['user'])){
        header( 'Location: index.php'  );
        die();
    }

    // Get line 1 and 5 from first page (to be used in newcriminalreport3 totals)
        $_SESSION['PendingCapDefs'] = $_POST['PendingCapDefs'];
        $_SESSION['PendingCapCases'] = $_POST['PendingCapCases'];
        $_SESSION['PendingNonCapDefs'] = $_POST['PendingNonCapDefs'];
        $_SESSION['PendingNonCapCases'] = $_POST['PendingNonCapCases'];
        $_SESSION['PendingDefsTotal'] = $_POST['PendingDefsTotal'];
        $_SESSION['PendingCasesTotal'] = $_POST['PendingCasesTotal'];

        $_SESSION['PendingCapDefsTotal'] = $_POST['PendingCapDefsTotal'];
        $_SESSION['PendingCapCasesTotal'] = $_POST['PendingCapCasesTotal'];
        $_SESSION['PendingNonCapDefsTotal'] = $_POST['PendingNonCapDefsTotal'];
        $_SESSION['PendingNonCapCasesTotal'] = $_POST['PendingNonCapCasesTotal'];
        $_SESSION['PendingTotalDefs'] = $_POST['PendingTotalDefs'];
        $_SESSION['PendingTotalCases'] = $_POST['PendingTotalCases'];
?>

任何人都知道发生了什么事？

的print_r（$ _ POST）：

Array ( [PendingCapDefs] => [PendingCapCases] => [PendingNonCapDefs] => [PendingNonCapCases] => [PendingDefsTotal] => [PendingCasesTotal] => [username] => 0 [PendingCapDefsTotal] => [PendingCapCasesTotal] => [PendingNonCapDefsTotal] => [PendingNonCapCasesTotal] => [PendingTotalDefs] => [PendingTotalCases] => ) 

<script type="text/javascript">
    $(window).unload( function () {
        // Line 1
        $('#PendingCapDefsInput').val($('#PendingCapDefs').html());
        $('#PendingCapCasesInput').val($('#PendingCapCases').html());
        $('#PendingNonCapDefsInput').val($('#PendingNonCapDefs').html());
        $('#PendingNonCapCasesInput').val($('#PendingNonCapCases').html());
        $('#PendingDefsTotalInput').val($('#PendingDefsTotal').html());
        $('#PendingCasesTotalInput').val($('#PendingCasesTotal').html());

        // Line 5
        $('#PendingCapDefsTotalInput').val($('#PendingCapDefsTotal').html());   
        $('#PendingCapCasesTotalInput').val($('#PendingCapCasesTotal').html()); 
        $('#PendingNonCapCasesTotalInput').val($('#PendingNonCapCasesTotal').html());   
        $('#PendingTotalDefsInput').val($('#PendingTotalDefs').html()); 
        $('#PendingTotalCasesInput').val($('#PendingTotalCases').html());   
    });
</script>

Answer 1

    $('#PendingCapDefsInput').val($('#PendingCapDefs').html());

输入元素没有html，因此在将表单数据发送到服务器之前，您将在页面卸载时擦除表单内容。由于您只是直接向服务器提交，为什么还要打扰jquery“按摩”呢？
