在页面之间传递数据 [英] Pass data between pages

问题描述

我正在使用phonegap上的移动应用程序，并且我需要在页面之间传递变量，例如: http://coenraets.org/apps/directory/jqm/index.html

I'm working on a mobile app on phonegap, and I need to pass variables between pages exactly like : http://coenraets.org/apps/directory/jqm/index.html

但是我的问题是我不能使用php文件. 我怎样才能做到这一点 ? 谢谢:)

but my problem is that I can't use a php file. How can I do that ? Thank you :)

我刚刚尝试了此处提到的LocalStorage: http: //docs.phonegap.com/en/1.6.1/cordova_storage_storage.md.html#localStorage 但它不起作用: 这是我的代码:

I just tried the LocalStorage which is mentionned here : http://docs.phonegap.com/en/1.6.1/cordova_storage_storage.md.html#localStorage but it doesn't work : here's my code :

第1页:

$(data).find("Book").each(function () {
        var temp = $(this).find("name").text();
        var temp1 = $("#champ").val().replace(" ", "") ;

        if (temp1 != "") {
            if (temp.toLowerCase().search(myRegExp) > -1) {
                $("#result_list").append("<li><a href='recherche_details.html' data-transition='pop'><img src='images/a.jpg' /><p><strong>Titre : " + temp + "</strong></p><p>Auteur : " + $(this).find("address").text() + "</p><p>Pays : " + $(this).find("country").text() + "</p></a></li>").listview("refresh") ;
                $envoi_search.attr("disabled", "");
                // Using the LocalStorage
                window.localStorage.setItem("titre" + i, temp);
                i++ ;
            }
        }
    });

第2页:

<script type="text/javascript" charset="utf-8">

        // Wait for Cordova to load
        document.addEventListener("deviceready", onDeviceReady, false);

        // Cordova is ready
        function onDeviceReady() {
            // keyname is now equal to "key"
            var value = window.localStorage.getItem("titre0");
            $("#result").append("Yoooo" + value + " !! you are here") ;
        }
    </script>

但是它不起作用. 你有什么主意吗?

but it doesn't work. Do you have any idea ?

推荐答案

在location.hash或location.search(查询字符串)中设置变量，然后在第二页上使用JavaScript进行检索.

Set your variable in either the location.hash or location.search (querystring), then retrieve it using JavaScript on the second page.

https://developer.mozilla.org/en/DOM/window .location#Properties

别忘了，当您检索location.hash或location.search时，您会想使用.substring(1)之类的东西来去除第一个字符(#或?):

Don't forget that when you retrieve location.hash or location.search, you'll want to strip the first character (# or ?) using something like .substring(1):

var hash = location.hash.substring(1);

另请参阅此问题，以了解解析location.search字符串的技术键和值.
