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; })();
};

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
});
