Question

所以这有点复杂

我使用phonegap创建了一个应用。我正在尝试实施“待办事项”清单。我找到了一个很好的示例javascript方法，我已将其放入主index.html文档中。

因此，当应用程序首次启动时，它可以正常运行并且看起来应该如此：

enter image description here

它允许我添加新的dos，检查一堆要删除，或点击按钮删除它们等。

但是当我关闭应用并重新加载它时，它会丢失所有样式并且删除按钮不再起作用：

但是，我点击ADD ITEM，新项目以他们应该的风格显示......

所以，这里是脚本的index.html头部的代码：

<script type="text/javascript" language="JavaScript">

    //Create a new To-Do
    function createNewToDo()
    {
        var todoDictionary = {};
        //Prompt the user to enter To-Do
        var todo="ASSIGNMENT NAME";
        var todolink="index.html#fastshutter";
        if (todo!=null)
        {
            if (todo == "")
            {
                alert("To-Do can't be empty!");
            }
            else

                //Append the new To-Do with the table

        var rowCount = table.rows.length;

        //Loop through all rows
        for(var i=0; i<rowCount; i++)
        {
            //delete row
            table.deleteRow(i);
            rowCount--;
            i--;
        }

        //Save
        saveToDoList();
    }




    </script>

和风格（也在头部）

<style type="text/css">

/ * BeginOAWidget_Instance_2127022：#gallery * /

.viewButton {
    background-color:Transparent;
    width:50px
    height:32px;
}

.deleteButton { 
    background-color:Transparent;
    width:30px;
    height:30px;
}

以下是实现页面的html代码：

<body bgcolor="#e0e0e0" onload="loadToDoList()" >

<div data-role="page" id="favlist">
<div data-role="header">
<h1><a href="#choose" data-role="button" data-icon="arrow-l" data-iconpos="right">BACK</a> Favourites </h1>
</div>
<div data-role="content">
  <button type="button" class="addToDo" onclick="createNewToDo()">ADD</button>
  <button type="button" class="removeTasks" onclick="removeCompletedTasks()">REMOVE</button>
  <br/><br/><br/>
  <table id="dataTable" width="100%" border="0">
  </table> 
 <a href="#choose" data-role="button" data-theme="a">CLOSE</a> 
</div>
</div>

所以我不确定jquerymobile css文件是否会干扰这个？

感谢您的任何建议

编辑：我能够弄清楚。我需要通过向jquery css添加一个新的按钮类来完全覆盖按钮元素的jquery移动CSS。在第一次运行并添加新项目时，它使用了我在HTML中添加的内联样式，但在重新加载时它会拉动标准样式
