在表单中有一个文本字段和一个表。如果我们在该文本字段中放置一个值,则需要在表格中显示相应的名称:
<form method="post" action="<?php $_SERVER['PHP_SELF']; ?>">
<center><table>
<tr><td>no</td><td><input type="text" name="no" autofocus></td></tr>
</table></center>
<br>
<br>
<center>
<table cellpadding="0" cellspacing="0" width="60%" border='1' bgcolor="#999999">
<thead>
<tr>
<th> Element_Number</th>
</tr>
</thead>
<?php
if(isset($_POST['no']))
{
$c=mysql_connect("localhost","root","");
mysql_select_db("test");
if(!$c)
{
echo "db prob".mysql_error();
}
$no=$_POST['no'];
$qry=mysql_query("select name from opt where no='$no'");
if(!$qry)
{
echo "ret".mysql_error();
}
if(mysql_num_rows($qry)!=0)
{
$row=mysql_fetch_array($qry);
$name=$row['name'];
}
else
{
echo "query Invalid";
}
echo "<td>" .$name."</td></tr>" ;
}
?>
使用此代码,值会在表格中输入,但是当下一个值输入到文本字段时,我想要将值经常添加到表格作为下一行

在ajax
的帮助下完成<form method="post" action="<?php $_SERVER['PHP_SELF']; ?>">
<center>
<table>
<tr><td>no</td><td><input type="text" name="no" autofocus></td></tr>
<tr><input type="button" name="submit" value="submit"></tr>
</table></center>
</form>
<br>
<br>
<center>
<table id="test_table" cellpadding="0" cellspacing="0" width="60%" border='1' bgcolor="#999999">
<thead>
<tr>
<th> Element_Number</th>
</tr>
</thead>
<tbody>
</tbody>
</table>
<script>
$(document).ready(function(){
$('#submit').click(function(){
var no=$('[name="no"]');
$.post('your_current_page_name.php',{"no":no},function(data){
$("#test_table> tbody").append(data);
});
});
});
</script>
<?php
if(isset($_POST['no']))
{
$c=mysql_connect("localhost","root","");
mysql_select_db("test");
if(!$c)
{
echo "db prob".mysql_error();
}
$no=$_POST['no'];
$qry=mysql_query("select name from opt where no='$no'");
if(!$qry)
{
echo "ret".mysql_error();
}
if(mysql_num_rows($qry)!=0)
{
$row=mysql_fetch_array($qry);
$name=$row['name'];
}
else
{
echo "query Invalid";
}
echo "<tr><td>" .$name."</td></tr>" ;
}
