Question

我对php中的while循环很困惑。我需要从sql数据库中检索数据并显示onclick按钮。但我不知道如何处理while循环。我希望我在这里犯了一个错误。提前致谢

<p>Show page <span onclick="show('Page1');">1</span>, <span onclick="show('Page2');">2</span>, <span onclick="show('Page3');">3</span>.
</p>

    <table width="100%" border="1" cellpadding="10" cellspacing="0" style="font-size:11px; font-family:verdana;" >
    <thead>
        <tr><td colspan ="6"><b>TITLE</b></td></tr>
        <tr>
        <th>Site ID</th>
        <th>Site Name</th>
        <th>Site Address</th>
        <th>Project Type</th>
        <th>Expected Date</th>
        <th>Number of Days Left</th>
        </tr>
    </thead>

<div id="Page1" class="page" style="">
        <div id="quotation">
<?php 
while($fiberexcel = mysqli_fetch_assoc($records)):
    $A1=$fiberexcel['SiteID0']; //1

    $A3=$fiberexcel['SiteAddress2'];    //3
    $A4=$fiberexcel['ProjectType3'];    //4
    $A13=$fiberexcel['ExpectDateABC'];


date_default_timezone_get('Asia/Colomb');
$A13=$fiberexcel['ExpectDateABC'];
$today= date('Y-m-d');

if (date('Y-m-d') <= $A13)

点击后，您可以在javascript中向该php发出一些xhr请求并从中获取响应，然后您可以将数据呈现给dom。

如何使用onclick javascript按钮多次使用while循环以适应不同的条件？
