Solution 1: 解决方案1:

You can pass values with changePage: 您可以使用changePage传递值:

$.mobile.changePage('page2.html', { dataUrl : "page2.html?paremeter=123", data : { 'paremeter' : '123' }, reloadPage : true, changeHash : true });

And read them like this: 并像这样阅读它们:

$(document).on('pagebeforeshow', "#index", function (event, data) {
    var parameters = $(this).data("url").split("?")[1];;
    parameter = parameters.replace("parameter=","");  
    alert(parameter);
});

Solution 2: 解决方案2:

Or you can create a persistent javascript object for a storage purpose. 或者,您可以创建一个持久性javascript对象以用于存储。 As long ajax is used for page loading (and page is not reloaded in any way) that object will stay active. 只要使用ajax进行页面加载(并且不会以任何方式重新加载页面),该对象就会保持活动状态。

var storeObject = {
    firstname : '',
    lastname : ''
}

Example: http://jsfiddle.net/Gajotres/9KKbx/ 示例: http//jsfiddle.net/Gajotres/9KKbx/

Solution 3: 解决方案3:

You can also access data from the previous page like this: 您还可以像这样从上一页访问数据:

$('#index').live('pagebeforeshow', function (e, data) {
    alert(data.prevPage.attr('id'));
});   

prevPage object holds a complete previous page. prevPage对象保存完整的上一页。

Solution 4: 解决方案4:

As a last solution we have a nifty HTML implementation of localStorage. 作为最后的解决方案,我们有一个很棒的localStorage HTML实现。 It only works with HTML5 browsers (including Android and iOS browsers) but all stored data is persistent through page refresh. 它仅适用于HTML5浏览器(包括Android和iOS浏览器),但所有存储的数据都可以通过页面刷新保持不变。

if(typeof(Storage)!=="undefined") {
    localStorage.firstname="Dragan";
    localStorage.lastname="Gaic";            
}

You can also use it with external relations in links (for me and my purpose its easier), so I wanted to share this: 您也可以将其与链接中的外部关系一起使用(对我和我的目的来说,它更容易),所以我想分享一下:

HTML: HTML:

 <a href="page1.htm?structure='123'">Structure</a>

JS: JS:

$( document ).on( "pageinit", "#page1", function( event ) {
  var parameters = $(this).data("url").split("?")[1];
  parameter = parameters.replace("structure=","");
  alert(parameter);
});

In my case, the structure='123' is created dynamically, nobody writes a fixed value '123' for dynamic purposes :-) 在我的情况下,structure ='123'是动态创建的,没有人为动态目的而写固定值'123':-)
