我正在使用yui来显示数据网格...
<?php

mysql_select_db($db_name);
//sets encoding to utf8
$result = mysql_query("select dStud_id,dMarkObtained1,dMarkObtained2,dMarkObtained3,dMarkTotal from tbl_internalmarkallot");
//$res = mysql_fetch_array($result);
while($res = mysql_fetch_array($result))
{
//print_r($res);
$JsonVar = json_encode($res);

当我加载页面时，这是我的脚本页面，我从数据库中获取第一行 但是连续数据没有显示在警告框中我如何接收数据网格中的数据
答案 0 :(得分：1)
while($res = mysql_fetch_array($result))
{
//print_r($res);
$JsonVar = json_encode($res);
echo "<input type='text' name='json' id='json' value ='$JsonVar'>";
}
看看这个while循环，我会假设它是数据库的最后一行而不是第一行被获取。我认为你正在将所有获取的行推送到单个输入元素中（将覆盖具有相同名称的多个输入ID）。
我建议将其改为
$i =0;
while($res = mysql_fetch_array($result))
{
//print_r($res);
$JsonVar = json_encode($res);
echo "<input type='text' name='json$i' id='json$i' value ='$JsonVar'>";
$i++;
}
你能检查这是否有帮助？您还需要更改YUI函数调用。
