用JS的数组缓存一些东西

var cache_index = new Array();   //首页的ajax缓存
//ajax 推荐的游戏和软件
function change_tuijian(sid,div_class){
    if(typeof(cache_index[sid])=="undefined") {
        $.post(APP_PATH + "index.php?m=game&c=index&a=tui_ajax", {sid: sid}, function (data) {
            var tmp_str = ‘‘;
            eval("var obj=" + data);
            for (var v in obj) {
                tmp_str += ‘<div class="each">‘;
                tmp_str += ‘<a hidefocus="true" onclick="display_show(\‘‘ + APP_PATH + ‘html/game/‘ + obj[v][‘catid‘] + ‘/‘ + obj[v][‘id‘] + ‘.html\‘)" class="thumb father_cover">‘;
                tmp_str += ‘<img src="‘ + obj[v][‘thumb‘] + ‘" />‘;
                tmp_str += ‘<span class="cover cover67"></span></a><div class="wenzi">‘;
                tmp_str += ‘<h5><a hidefocus="true" href="javascript:void(0);" onclick="display_show(\‘‘ + APP_PATH + ‘html/game/‘ + obj[v][‘catid‘] + ‘/‘ + obj[v][‘id‘] + ‘.html\‘)">‘ + obj[v][‘title‘] + ‘</a></h5>‘;
                tmp_str += ‘<p>‘ + obj[v][‘version‘] + ‘ | ‘ + obj[v][‘filesize‘] + ‘</p>‘;

                tmp_str += ‘</div></div>‘;
            }
            tmp_str += ‘<script type="text/javascript" src="‘ + APP_PATH + ‘statics/js/game/list_again.js"></script>‘;
