select下拉框的数据是在ajax里面生成的,如何才能取得并上传所选的值
有这么一个情况,下拉框里的选项是后台动态生成的,所以下拉框的代码没有在html里面写,而是写在ajax里面。那这种情况下,我该如何取得用户所选的值并上传到后台某个php中呢?
html的代码(selectdata.html):
<html>
<head>
<title></title>
        <script src="http://code.jquery.com/jquery-1.9.1.js"></script>
        <script src="selectdata.js"></script>
        <script type="text/javascript">
                $(document).ready(function(){
                        showselect($("select"));
                });
        </script>
</head>
<body>
<div id="select" name="select "class="select"></div>
<input type="submit" class="button" value="echo" />
</body>
</html>


ajax的代码(selectdata.js):
function showselect(htmlContainer){
$.ajax({
            url:"selectdata.php",
            type:"post",
            dataType:"json",
            success:function(data){
                var select = document.createElement("select");
                for(var name in data.sex){
                    var option = document.createElement("option");
                    option.name = name;
                    option.innerHTML = name;
                    option.value = data.sex[name];
                    select.appendChild(option)
                }
                document.getElementsByTagName("body")[0].appendChild(select)
            }
        });
}


后台生成select数据部分的php文件():
<?php
        include ("JSON.php");
        $json = new Services_JSON();

        $arr = array("sex select"=>"","man"=>"male","woman"=>"famale","other"=>"other");
        $str = array("sex"=>$arr);

        $json&nb
