我怎样才能完成我的职责范围？单击下拉列表(语言)中的项目后，我希望在网页上有一个带有一些静态选项的下拉列表
<td align="left">
<SELECT name="language" >
<OPTION value="ro" selected>Romana</OPTION>
<option value="en">English</option>
<option value="de">Deutsch</option>
</SELECT>
选择一个我希望 $language 变量获取新值的选项
值并重新加载页面，并更改 $language 变量。
在目标网页上，我得到了一个 PHP 函数，该函数根据 $language 变量值返回 HTML 文本元素(这部分已经在工作)。
以下是我的完整设置:
index.php
<?php
if( isset( $_GET['target'] ) )
$target = $_GET['target'];
else
$target = "productie";
?>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Frameset//EN">
<!-- saved from url=English/index.php -->
<HTML><HEAD><META content="IE=7.0000" http-equiv="X-UA-Compatible">
<TITLE>website name</TITLE><!--
-->
</HEAD>
<FRAMESET frameSpacing=0 border=0 frameBorder=NO rows=65,* cols=*>
<FRAME noResize marginHeight=0 src="web_files/top.html" name=topFrame marginWidth=0 scrolling=no>
<FRAMESET frameSpacing=0 border=0 frameBorder=NO cols=224,*>
<FRAME noResize marginHeight=0 src="web_files/menu.php?target=<?php echo $target?>" name=leftFrame marginWidth=0>
<FRAME marginHeight=0 src="web_files/right.php?target=<?php
echo $target;
if( isset( $_GET['id'] ) )
?>" name="contentFrame" id="content" marginWidth=0>
</FRAMESET>
</FRAMESET>
</HTML>
下一个是 menu.php 我想在这里放入选项列表

最佳答案
您可以使用 onchange 获取新选择的选项的值事件。
$(document).ready(function(){
$('select[name=language]').change(function() {
});
});
如果您想提交数据，请添加ajax post
$(document).ready(function(){
$('select[name=language]').change(function() {
var _lang = $( "select['name=language'] option:selected" ).text(); //Get the text of the selected option, you can use .val() instead to get the the content of the value attribute
$.post( "languageHandler.php",{ language: _lang}, function(data) {
$('body').append(data); //Append the new data to body
});
});
});
