pushState与ajax实现无刷新加载

一.JS代码：

$(document).ready(function() {

    getContent();//初始化页面

    $("nav a").click(function() {
        var href = $(this).attr("href");
        history.pushState("", "", href);//ajax可前进后退
        getContent();//执行ajax
        return false;//阻止默认事件
    });
});

var getContent = function() {
    hash = window.location.hash;
    if (hash == "#/") { load_page("Home"); } else 
    if (hash == "#/blog") { load_page("Blog"); } else 
    if (hash == "#/productos") {load_page("Productos"); } 
}

var load_page = function(inf){
    $.ajax({
        type: "GET",
        url: "http://localhost:8080/test.php",
        data: {page: inf},
        cache: false,
        success: function(result) {
            $("#contenido").html(result);
        }
    });
}

window.onpopstate = function(event) {//点击前进后退时执行
    getContent();
};

　　

二.html代码

<nav>
  <a href="#/">Home</a>
  <a href="#/blog">blog</a>
  <a href="#/productos">productos</a>
</nav>

<section id="contenido" role="main">

</section>

三.test.php

<?php 

echo $_GET['page'];


?>
