让我的后退和前进按钮工作与ajax

getting my back and forwards buttons to work with ajax

本文关键字：按钮 工作 ajax 我的      更新时间：2023-09-26

多亏了我精心修改的一些代码，我的网站工作得更快了，但我希望浏览器的后退/前进按钮能正常工作。现在，使用下面的代码，浏览器地址栏永远不会改变。当有人点击"返回"时，它会把他们带出应用程序。

是否有任何简单的方法来改变这一点，使浏览器的后退/前进按钮工作?或者有人能给我指出正确的方向。谢谢你的帮助。

$(document).on("ready", function () {
    //I want to load content into the '.page-content' class, with ajax
    var ajax_loaded = (function (response) {
        $(".page-content")
        .html($(response).filter(".page-content"));
        $(".page-content .ajax").on("click", ajax_load);

    });

    //the function below is called by links that are described 
    //with the class 'ajax', or are in the div 'menu' 
    var history = [];
    var ajax_load = (function (e) {
        e.preventDefault();

        history.push(this);
        var url = $(this).attr("href");
        var method = $(this).attr("data-method");

        $.ajax({
            url: url,
            type: method,
            success: ajax_loaded
        });
    });

    //monitor for clicks from menu div, or with
    //the ajax class
    //why the trigger?
    $("#menu a").on("click", ajax_load);
    $(".ajax").on("click", ajax_load);
    $("#menu a.main").trigger("click");

});

这是一种检测你在问什么的方法。

听我说，按后退和前进键是一项危险的任务。

window.onload = function () {
    if (typeof history.pushState === "function") {
        history.pushState("someState", null, null);
        window.onpopstate = function () {
            history.pushState("newState", null, null);
            // Handle the back (or forward) buttons here
            // Will not handle refresh, use onbeforeunload for this.
        };
    }
}

您可以使用jquery地址插件(http://www.asual.com/jquery/address/)。它有一个事件，当用户按下后退/前进按钮时检测。

$.address.externalChange(function() { console.log('back/forward pressed'); });

据我所知，没有办法区分后退和前进

你一定要检查History.js下面是一些示例代码:-

  (function(window,undefined){
    // Prepare
    var History = window.History; // Note: We are using a capital H instead of a lower h
    if ( !History.enabled ) {
         // History.js is disabled for this browser.
         // This is because we can optionally choose to support HTML4 browsers or not.
        return false;
    }
    // Bind to StateChange Event
    History.Adapter.bind(window,'statechange',function(){ // Note: We are using statechange instead of popstate
      var State = History.getState(); // Note: We are using History.getState() instead of event.state
      //History.log(State.data, State.title, State.url);
      var goto_url = State.url;            
      $.ajax({
          url: goto_url,
          dataType: "script"
      });
    });
  })(window);
