Question

如何从对象的数据中提取数据并将其动态添加到列表视图中

function (){
   var person = {
       title: "ddd",
       mes: "sss",
       op: {},
       tel: 2
   };  
}

数据将来自json服务器

<div data-role="page" id="page1">
    <div data-role="header">
        <h1>Заголовок</h1>
    </div>

    <ul data-inset="true" id="ideaposits" data-role="listview" data-split-icon="gear">
        <script type="text/html" id="list">
        <li>
            <a class="ui-btn ui-icon-carat-r " href="#page2">
                <h2 class="title"></h2>
                <p class="mes"></p>
            </a>
            </li>
        </script> 
    </ul>
</div>

然后转到第二个屏幕page2 ........

Answer 1

首先，制作＆＃34;模板＆＃34;元素隐藏：

                <li style="display:none">
                    <a class="ui-btn ui-icon-carat-r " href="#page2">

                        <h2 class="title"></h2>
                        <p class="mes"></p>

                    </a>
                </li>

然后，更改您的javascript以复制模板项并填写值，然后显示它：

function (){
        var person = {
          title: "ddd",
          mes: "sss",
          op: {},
          tel: 2
        }; 

        var li = $("li"); 
        var newLi = li.clone();
        newLi.find(".title").text(person.title);
        newLi.find(".mes").text(person.mes);
        newLi.show();
        li.after(newLi);
}

  });
}


//main process 
setInterval(function(){

},4000);

//onload
