jQuery Mobile的列表视图单击项目 - 参数传递到另一个页面 [英] Jquery Mobile Listview Clicked Item - Pass parameter to another page

问题描述

我有一个index.html页面。另外这款页包含大量的页面像#home，#list #contacts等。

I've a index.html page. Also this page contains lots of page like #home, #list #contacts etc.

在#list部分动态地从我的网页数据，并生成列表视图。我想，当用户单击任何列表项目，重定向到#imageDetail页面并传递图像URL页面，并显示图片

in #list part i dynamically get data from my webpage and generate listview. I want that, when user click any of list item, redirect to #imageDetail page and pass image URL to page and show image

这里是#imageDetail页面部分

here is the #imageDetail page part

    <div data-role="page"  id="detailedIMAGE" data-theme="a">
      <div data-role="header" data-theme="b" data-position="fixed">
        <h1>Image Detail</h1>
        </div>
            <div data-role="content">       
            <img id="imageDetayURL" name="imageDetayURL" src="glyphish-icons/158-wrench-2.png"/>
            <input type="text" disabled="disabled" id="brewername" name="brewername" />
            </div>
        </div>  
    </div>

和低于code是我的javascript code动态获取JSON数据。

And below code is my javascript code to get json data dynamically.

    <script>
    $('#last5').live("click", function() {
        $.ajax({
            url: "http://mysqlservice.com/getdata.json",
            dataType: 'jsonp',
            success: function(json_results){
                $("#imageListDetay").html('');
                console.log(json_results);
                $('#imageListDetay').append('<ul data-role="listview" id="tweetul" data-theme="c"></ul>');
                listItems = $('#imageListDetay').find('ul');
                $.each(json_results.results, function(key) {
                    html = '<h3>'+json_results.results[key].screen_name+'</h3><span id="detailed_image">'+json_results.results[key].resim_url+'</span><img WIDTH=200 HEIGHT=100 src="http://mywebpage.org/upload/'+json_results.results[key].resim_url+'" /><p class="ui-li-bside"><img WIDTH=8 HEIGHT=13 src="images/07-map-marker.png"/> '+json_results.results[key].adres_data+'</p>';
                    listItems.append('<li><a  name="imageDetayGoster" href="#detailedIMAGE">'+html+'</a></li>');
               });
                $('#imageListDetay ul').listview();
            },
                error: function (XMLHttpRequest, textStatus, errorThrown) {
                //error
            }
        });
    })


    $("#detailedIMAGE").live("pagebeforeshow", function (e, data) { 
         var brewername = $('#detailed_image',data.prevPage).text();
         $('#brewername').val(brewername);  
         $('#imageDetayURL').attr('src', 'http://mobil.harmankaya.org/'+brewername);
         alert(brewername);
     });
    </script>

问题是换页警报（brewername）火灾后。但列表中的所有图片网址列表视图中没有列出我的选择。

The problem is after page change alert(brewername) fires. But list all image urls that listed in listview not my selected.

如何能我修复了这个问题。

How can i fixed this issue

先谢谢了。

推荐答案

好吧，这是我的路，而且运作非常良好。

Well, this is my way and works very good.

HTML

<div data-role="page" id="myPage">
<div data-role="content" id="myContent">
    <ul data-role="listview" data-inset="true/false/whatever" id="myList"></ul>
</div>
</div>

的JavaScript

Javascript

$("#myPage").live("pageshow",function(event){
       // get your id from LINK and parse it to a variable
    var json_list_callback = getUrlVars()[id];

       // verify the URL id
    if (json_list_callback === '') {json_list_callback === ''} //or what value you want

       // define your path to JSON file generated by the ID declared upper
    var json_URL = 'http://your.path.to.json.file.php.json?id=' + json_list_callback;

       // get the JSON data defined earlier and append to your LIST
    $.getJSON(json_URL,function(data){
        var entries = data;
        //populate our list with our json data
        $.each(entries,function(index,entry){
                // i use dummy data here, you can have whatever you want in youre json
            $("#myList").append(
               '<li>' +
                        // remember that this "page.html?id=' + entry.json_id + '" will be the link where getUrlVars will get the id declared earlier in function
                  '<a href="page.html?id=' + entry.json_id + '">' + entry.json_title + '<\/a>' +
               '<\/li>'
            );
        });
          //must refresh listview for layout to render
        $("#myList").listview("refresh");
    });
});
    //this function gets from URL the id, category, whatever you declare like this: getUrlVars()['id'] or getUrlVars()['category'] after last symbol of "?"
    // you can define your own symbol with this function
function getUrlVars() {
var vars = [],
    hash;
var hashes = window.location.href.slice(window.location.href.lastIndexOf('?') + 1).split('&');
for (var i = 0; i < hashes.length; i++) {
    hash = hashes[i].split('=');
    vars.push(hash[0]);
    vars[hash[0]] = hash[1];
}
return vars;
}

这对我的作品就像一个魅力和我使用很频繁！
