input 之间怎么传递数据是在同一页面
怎么把pripath和tfilename2 的数据 传给tfilename 就一个页面
页面提交后tfilename 值得到 pripath和tfilename2 的数据
<input name="tfilename" type="hidden" id="tfilename" value="<?=$pripath?><?=$tfilename2?>">
<td height="25" bgcolor="#FFFFFF">根目录</td>
<input name="pripath" type="text" id="pripath" value="<?=$pripath?>" size="30">
<input name="tfilename2" type="text" id="tfilename2" value="<?=$tfilename2?>" size="16">------解决思路----------------------
<script type="text/javascript">
function add(){
document.getElementById('tfilename').value = document.getElementById('pripath').value + '' + document.getElementById('tfilename2').value;
}
</script>
<input name="tfilename" type="hidden" id="tfilename" value="<?=$pripath?><?=$tfilename2?>">
<td height="25" bgcolor="#FFFFFF">根目录</td>
<input name="pripath" type="text" id="pripath" value="<?=$pripath?>" size="30">
<input name="tfilename2" type="text" id="tfilename2" value="<?=$tfilename2?>" size="16">
<input type="button" name="b1" onclick="add()" value="传递" >点传递按钮。
------解决思路----------------------
<?php

$pripath = "c:\windows\";
$tfilename2 = "test.txt";

<form action="" method="post" name="file_form" id="file_form"/>
<table>
<tr>
<input name="tfilename" type="hidden" id="tfilename" value="<?php echo $pripath; ?><?php echo $tfilename2; ?>" />
<td height="25" bgcolor="#FFFFFF">根目录</td>
<input name="pripath" type="text" id="pripath" value="<?php echo $pripath; ?>" size="30">
<input name="tfilename2" type="text" id="tfilename2" value="<?php echo $tfilename2; ?>" size="16">
</tr>
<tr>
<td><input type="submit" name="submit"/></td>
</tr>
</table>
</form>
<?php
if (isset($_POST['submit'])) {
$pripath = $_POST['pripath'];
$pripath = (!get_magic_quotes_gpc()) ? addslashes($pripath) : $pripath;
$tfilename2 = $_POST['tfilename2'];
$tfilename2 = (!get_magic_quotes_gpc()) ? addslashes($tfilename2) : $tfilename2;
$str = "<script>
";
$str .= "document.getElementById('tfilename').value = '{$pripath}{$tfilename2}';
";
$str .= "document.getElementById('pripath').value = '{$pripath}';

$str .= "document.getElementById('tfilename2').value = '{$tfilename2}';

每个人都需要一台速度更快、更稳定的 PC。随着时间的推移,垃圾文件、旧注册表数据和不必要的后台进程会占用资源并降低性能。幸运的是,许多工具可以让 Windows 保持平稳运行。
