h5History 模式的实例教程(2)-木庄网络博客

四、下面贴一个类似vue-router的HTML5模式的例子，纯属加深理解，写的很粗糙。

<!DOCTYPE html><html lang="en"><head><meta charset="UTF-8"><title>HTML5 History 模式(第二版)</title><link rel="stylesheet" type="text/css" href="css/style.css?1.1.10"><style type="text/css">.container-bg{width:1000px; overflow: hidden; margin-right: 0 auto;}.pagination{width: 1000px; background-color: #d8d8d8; height: 30px; line-height: 30px;}.pagination li{width: 100px; height: 30px; background: red; float: left; cursor: pointer; color:#fff; margin: 0 10px 0 0;}</style></head><body><div class="container-bg"><ul class="pagination"><li>1</li><li>2</li><li>3</li></ul><ul class="ptting"></ul></div><script type="text/javascript" src="js/jquery-3.2.1.min.js?1.1.10"></script><script type="text/javascript">
    history.replaceState(null, "页面标题", "http://127.0.0.1:3000/lmw/0");//当页面载入时候，把url地址修改var searchObject = {};/*此对象用来保存下面pushState的URL作为key值，ajax要查询的ID为val
                           *例如：searchObject = {"http://127.0.0.1:3000/lmw/0":0}*/var factory = function(){var addva = document.location.href;//获取完整URLvar query = searchObject[addva];//找到该URL对应的值        query = (query == undefined ? 0 :query);//发起ajax加载页面        $.get("/page?page="+query,function(data){var data2 = JSON.parse(data);var ele = ""for(var i=0;i<data2.data.length;i++){
                        ele += '<li>'+data2.data[i].name+'</li>'}
                    $('.ptting').html(ele)
                     
                }) 
        };    //点击分页切换事件            $(".pagination li").click(function(){var query=$(this).index();
                $.get("/page?page="+query,function(data){var data2 = JSON.parse(data);var ele = ""for(var i=0;i<data2.data.length;i++){
                        ele += '<li>'+data2.data[i].name+'</li>'}
                    $('.ptting').html(ele)                    
                    history.pushState({pageIndex : 1}, "", "http://127.0.0.1:3000/lmw/"+query);//把当前pushState的url，和ajax查询的值存入对象，以供触发pushState事件的时候使用                    searchObject["http://127.0.0.1:3000/lmw/"+query] = query
                     
                })
            })//浏览器前进或者后退的时候触发popstate事件if (history.pushState) {
    window.addEventListener("popstate", function() {
        factory()                              
    });
 
    factory()
};</script></body></html>

顺便贴一个node.js中的server代码，为了测试，很随意简单的写了一个

var fs = require('fs')var path = require('path')var express = require('express')var app = express();
app.use(express.static('./public'));var router = express.Router();
router.get('/page',function(req,res){var page = req.query.pagetry{var text = fs.readFileSync('./data'+page+'.json');
        res.json(text.toString())
    }catch(err){
        res.send('哈哈！傻逼，没有拉！')    
    }
     
})
 
app.use(router)
 
app.listen(3000)

1	`注意：history.pushState({pageIndex : 1},` `"",` `"http://127.0.0.1:3000/lmw/"+query)这里第三个参数写了完整的绝对路径，如果写成"/lmw/"+query这样的相对路径，会随着query值得增加无限在url后面追加，因为相对路径它一定是相对于当前的URL`

服务端放了data0.json,data1.json,data2.json来模拟一下数据库取数据，服务器更具前端传来的index值（0/1/2），来匹配读取data*.json文件，再发给前端
