本文为大家分享了nodejs个人博客开发的分配数据，具体内容如下

使用回掉大坑进行取数据

能看明白的就看，看不明白的手动滑稽

/*** 首页控制器*/var router=express.Router();var pageSize=5;router.get('/',function(req,res,next){ var currentPage=parseInt(req.params.page); var cid=0; var categoryModel=F.model("category"); var articleModel=F.model("article"); // 分类数据 categoryModel.getAllList(function(err,categoryList){ // 文章条数 articleModel.getCount(cid,function(err,nums){ // 文章分页 articleModel.getArticlePager(cid,currentPage,pageSize,function(err,articleList){ var nextPage=(currentPage+1)>=Math.ceil(nums[0].num/pageSize) ? Math.ceil(nums[0].num/pageSize) : currentPage+1; var prePage=(currentPage-1)<=0 ? 1 : currentPage-1; // 归档 articleModel.getArchives(function(err,allArticleTime){ var newArticleTime=[]; for(var i=0;i<allArticleTime.length;i++){ newArticleTime.push(F.phpDate("y年m月",allArticleTime[i].time)); } var data={ categoryList:categoryList, articleList:articleList, cid:cid, nextPage:nextPage==0 ? 1 : nextPage, prePage:prePage, allArticleTime:newArticleTime, currentPage:currentPage }; res.render("home/index",data); }); }); }); }); //F.model("category").addCate({"name":"测试"}); //F.model("category").saveCate({"name":"测试1"},"id=4"); //F.model("category").delCate("id=4"); //res.render("home/index");});module.exports=router;

文章模型：

/*** 文章模型文件*/module.exports={ getCount:function(categoryId,callback){ var condition=""; if(categoryId!=0){ condition="where category_id="+categoryId; } var sql="select count(*) num from article "+condition; db.query(sql,callback); }, getArticlePager:function(categoryId,currentPage,pageSize,callback){ if(currentPage<=0||!currentPage) currentPage=1; var start=(currentPage-1)*pageSize; var end=pageSize; var condition=""; if(categoryId!=0){ condition="where category_id="+categoryId; } var sql="select * from article "+condition+" order by time desc limit "+start+","+end; db.query(sql,callback); }, getArchives:function(callback){ db.query("select time from article order by time desc",callback); }};
