Question

所以，我会问你们其中一个天才在这里寻求帮助，因为我确信有人能够解决我想做的事情......

我有一个html表

    <body>
<div id="style">
<div class="disktext">
</p>
 <table width='190' border='0' cellspacing='0' cellpadding='1'>
        <tr><td BGCOLOR='#0066FF'><font color='white'>Disk Space</font></td></tr>
        <tr onclick="toggleNextRow(this)"><td BGCOLOR='#FFFFFF'`enter code here`><?php echo $drive1;?>\<?= $freeSpaceC ?> (of <?= $totalSpaceC ?>)</td></tr>
        <tr class="hiddenRow">
            <td bgcolor='#FFFFFF'>
                <div class="disk">
                    <div class="used" style="width: <?= $barWidthC ?>px"><?= $diskStatusC->usedSpace() ?>%&nbsp;</div>
                </div>
            </td>
        </tr>
        <tr onclick="toggleNextRow(this)"><td bgcolor='#FFFFFF'><?php echo $drive2;?>\<?= $freeSpace1 ?> (of <?= $totalSpace1 ?>)</td></tr>
        <tr class="hiddenRow">
            <td bgcolor='#FFFFFF'>
                <div class="disk">
                    <div class="used" style="width: <?= $barWidth1 ?>px"><?= $diskStatus1->usedSpace() ?>%&nbsp;</div>
                </div>
            </td>
        </tr>
        <tr onclick="toggleNextRow(this)"><td bgcolor='#FFFFFF'><?php echo $drive3;?>\<?= $freeSpace2 ?> (of <?= $totalSpace2 ?>)</td></tr>
        <tr class="hiddenRow">
            <td bgcolor='#FFFFFF'>
                <div class="disk">
                    <div class="used" style="width: <?= $barWidth2 ?>px"><?= $diskStatus2->usedSpace() ?>%&nbsp;</div>
                </div>
            </td>
        </tr>
        <tr onclick="toggleNextRow(this)"><td bgcolor='#FFFFFF'><?php echo $drive4;?>\<?= $freeSpace3 ?> (of <?= $totalSpace3 ?>)</td></tr>
        <tr class="hiddenRow">
            <td bgcolor='#FFFFFF'>
                <div class="disk">
                    <div class="used" style="width: <?= $barWidth3 ?>px"><?= $diskStatus3->usedSpace() ?>%&nbsp;</div>
                </div>
            </td>
        </tr>
        <tr onclick="toggleNextRow(this)"><td bgcolor='#FFFFFF'><?php echo $drive5;?>\<?= $freeSpace4 ?> (of <?= $totalSpace4 ?>)</td></tr>
        <tr class="hiddenRow">
            <td bgcolor='#FFFFFF'>
                <div class="disk">
                    <div class="used" style="width: <?= $barWidth4 ?>px"><?= $diskStatus4->usedSpace() ?>%&nbsp;</div>
                </div>
            </td>
        </tr>
        <tr onclick="toggleNextRow(this)"><td bgcolor='#FFFFFF'><?php echo $drive6;?>\<?= $freeSpace5 ?> (of <?= $totalSpace5 ?>)</td></tr>
        <tr class="hiddenRow">
            <td bgcolor='#FFFFFF'>
                <div class="disk">
                    <div class="used" style="width: <?= $barWidth5 ?>px"><?= $diskStatus5->usedSpace() ?>%&nbsp;</div>
                </div>
            </td>
        </tr>
        <tr onclick="toggleNextRow(this)"><td bgcolor='#FFFFFF'><?php echo $drive7;?>\<?= $freeSpace6 ?> (of <?= $totalSpace6 ?>)</td></tr>
        <tr class="hiddenRow">
            <td bgcolor='#FFFFFF'>
                <div class="disk">
                    <div class="used" style="width: <?= $barWidth6 ?>px"><?= $diskStatus6->usedSpace() ?>%&nbsp;</div>
                </div>
            </td>
        </tr>
    </table>

我想做的是使用php变量来定义是否应显示某一行＆＃34;内置＆＃34;

所以以下是我正在使用的if语句，这是有效的，但我无法解决如何在这种状态下使用它。

    if ($drive1visible > "0") {
    try {
}

我想采取表格的行，例如。

<tr onclick="toggleNextRow(this)"><td bgcolor='#FFFFFF'><?php echo $drive2;?>\<?= $freeSpace1 ?> (of <?= $totalSpace1 ?>)</td></tr>
        <tr class="hiddenRow">
            <td bgcolor='#FFFFFF'>
                <div class="disk">
                    <div class="used" style="width: <?= $barWidth1 ?>px"><?= $diskStatus1->usedSpace() ?>%&nbsp;</div>
                </div>
            </td>
        </tr>

并使其仅在满足变量条件时才创建该行我试过了

 if ($drive1visible > "0") {
        try {
<tr onclick="toggleNextRow(this)"><td bgcolor='#FFFFFF'><?php echo $drive2;?>\<?= $freeSpace1 ?> (of <?= $totalSpace1 ?>)</td></tr>
            <tr class="hiddenRow">
                <td bgcolor='#FFFFFF'>
                    <div class="disk">
                        <div class="used" style="width: <?= $barWidth1 ?>px"><?= $diskStatus1->usedSpace() ?>%&nbsp;</div>
                    </div>
                </td>
            </tr>
}

但它不起作用......

希望有人可以帮助我，或者告诉我它不可能，非常感谢！

你试错了..试试这个..

<?php if ($drive1visible > 0) { ?>
<tr onclick="toggleNextRow(this)"><td bgcolor='#FFFFFF'><?php echo $drive2;?>\<?= $freeSpace1 ?> (of <?= $totalSpace1 ?>)</td></tr>
            <tr class="hiddenRow">
                <td bgcolor='#FFFFFF'>
                    <div class="disk">
                        <div class="used" style="width: <?= $barWidth1 ?>px"><?= $diskStatus1->usedSpace() ?>%&nbsp;</div>
                    </div>
                </td>
            </tr>
<? php  } ?>
