Jquery Asual Address - 后退按钮PopState

标签: jquery history pushstate

我正在尝试使用Asual Address插件,以便我的后退按钮可用于ajax调用。我很困惑这项工作和我发现的每个教程如何表达不同。我无法让他们中的任何一个工作。

我有一个简单的ajax页面。它只是调用图像:

使用Javascript:

<script type="text/javascript">    


$("a").live("click", function(event) {      
    url = $(this).attr("href");
     $.address.value($(this).attr('href')); 
    event.preventDefault();
        $.ajax({
            type: "get",
            url: "/"+url+".php",
            data: "",
            dataType: "html",
            success: function(html){
                jQuery('#Right_Content').hide().html(html).fadeIn(1000);
            },
         })

});
</script>

我的Html看起来像这样:

<body>
<a href="push1" onclick="return false;" >Image 1</a>
<a href="push2" onclick="return false;">Image 2</a>  

<div id="Right_Content"></div>

</body>

使用上面的代码,当我点击链接时,它会进行ajax调用,加载图片并更改网址。这工作正常。我的问题是后退按钮。当我单击后退按钮时,URL会更改为上一个URL,但页面上的内容保持不变。我认为这与“popstate”有关,并将其添加到我的js中。我只是不知道该怎么做。

有人可以向我解释popstate是如何工作的,以及我如何将它添加到我的上面的代码,以便我的后退按钮工作。谢谢。

我的任务是允许用户返回某些页面,并防止从其他页面返回没有他将丢失数据的消息。我以这种方式结束了实施:

$(".-step-1-").click(function () {
   $.address.value("");
});

$(".-step-2-").click(function () {
    $.address.value("finances");
});

$(".-step-3-").click(function () {
    $.address.value("cofirmation");
});

global.previousPage = null;
$.address.init(function () {
}).change(function () {
}).externalChange(function (event) {
    if (global.previousPage == null) {
        $.address.value("");
    } else {
        showPageExternal(event.pathNames);
    }
}).internalChange(function (event) {
    global.previousPage = event.pathNames;
    showPage(event.pathNames);
});

var showPageExternal = function (pathName) {
    if (global.previousPage == null ||
        ("").localeCompare(global.previousPage) === 0 ||
        ("finances").localeCompare(global.previousPage) === 0) {
        showPage(pathName);
    }
    else {
        //This mean is coming from "confirmation" page
        global.blockUI($("#browserBackMessage"));
    }
};

var showPage = function (pathName) {
    if (("").localeCompare(pathName) === 0) {
        $(".step").hide();
        $(".-step-1").show();
    }
    if (("finances").localeCompare(pathName) === 0) {
        $(".step").hide();
        $("#finances").show();
    }
    if (("confirmation").localeCompare(pathName) === 0) {
        $(".step").hide();
        $("#confirm").show();
    }
};

global = function globalVariable() {
    return (function () { return this; })();
};

这是我在http://www.isaac.nl/en/

上使用的内容

我在那里有这个HTML:

<div id="main-menu">    
  <a class="history" href="#home">Home</a>
  <a class="history" href="#who">who</a>
  <a class="history" href="#what"></a>
  <a class="history" href="#where"></a>  
</div>

在js文件中我这样做:

$.address.init(function(event) {
  // All elements with the "history" class will be "addressed". When they get clicked
  // the href will get used as the new #part of the URL
  $('.history').address();

}).change(function(event) {
  //Every time the url part changes this will be called. 

  // As an example here I determine the # part of the URL and default to 'home'
  var hash = event.path.substring(1);
  hash = hash? hash.toLowerCase(): 'home';

  //.. do the stuff here that you need to do when hash has a certain value
});
