form表单用ge方式提交时ie显示中文参数乱码

有网友说 通过给form表单添加accept-charset="gb2312"和 onsubmit="document.charset='gb2312'" 但这样没能解决我的问题，我的源码是这样的：

这样做后，ie搜索还是不能成功，

后这样就可以了：

    <form method="get" target="_blank" id="searchform" name="searchform" accept-charset="gb2312" onsubmit="document.charset='gb2312';">
                                    <input type="hidden" value="1" name="searchtimes" />
                                    <input type="hidden" value="simple" name="kind" />
                                    <input type="hidden" name="client_id" value="web_search" />
                                    <input type="hidden" value="qx" name="suchen_match" />
                                    <input type="hidden" name="suchen_way" value="Ya" />
                                    <input type="hidden" name="show_type" value="wenzi" />
                                    <input type="hidden" name="library_id" value="all" />
                                    <input type="hidden" name="suchen_type" value="1" />
                                    <input type="hidden" name="recordtype" value="all" />                                  
                                    <input type="text" class="search_input2" size="35" name="suchen_word" id="suchen_word" style="300px" />
                                    <input type="submit" value="校内提交" class="btn_seac" id="searchin" />
                                    <input type="submit" value="校外提交" class="btn_seac" id="seachout" />
                                </form>
                                <script>
                                    $(function () {                                       
                                        $("#searchin").click(function () {
                                            searchform.action = "http://10.32.0.10/opac_two/search2/searchout.jsp";
                                            $("#searchform").charset = "gb2312";
                                            $("#searchform").submit();
                                        })
                                        $("#seachout").click(function () {
                                            searchform.action = "http://218.107.150.8/opac_two/search2/searchout.jsp";
                                            $("#searchform").charset = "gb2312";
                                            $("#searchform").submit();                                            
                                        })
                                    })
                                </script>
