Question

我在我的项目中使用Asp.net和Mobile jquery。我想在单击向上和向下按钮中按钮文本更改。它在System Chrome浏览器中完美运行。但我的移动浏览器 - opera mobile，它不显示文本。（按钮是空白甚至上下也不显示。）什么是错误？。

我希望你能理解我的问题。我在下面提供我的代码以供参考......

ASPX -

<div id="body" class="ui-content ui-body-a" > 
        <div class="ui-grid-b">                
            <div class="ui-block-a"><asp:Button ID="Button1" runat="server" Text="Button" /></div>
            <div class="ui-block-b"> <asp:Button ID="Button2" runat="server" Text="Button" /></div>             
            <div class="ui-block-c"> <asp:Button ID="btnUp" runat="server" Text="UP" onclick="btnUp_Click" /></div>    
            <div class="ui-block-a"><asp:Button ID="Button3" runat="server" Text="Button" /></div>
            <div class="ui-block-b"><asp:Button ID="Button4" runat="server" Text="Button" /></div>
            <div class="ui-block-c"> <asp:Button ID="Button5" runat="server" Text="Button" /></div>
            <div class="ui-block-a"><asp:Button ID="Button6" runat="server" Text="Button" /></div>
            <div class="ui-block-b"><asp:Button ID="Button7" runat="server" Text="Button" /></div>
            <div class="ui-block-c"> <asp:Button ID="Button8" runat="server" Text="Button" /></div>
            <div class="ui-block-a"><asp:Button ID="Button9" runat="server" Text="Button" /></div>
            <div class="ui-block-b"><asp:Button ID="Button10" runat="server" Text="Button" /></div>                       
            <div class="ui-block-c"><asp:Button ID="btnDown" runat="server" Text="DOWN" onclick="btnDown_Click" /></div>

在js文件中查找按钮样式代码。我想，..按钮有文字，但它可能是摆动或折叠。尝试在各种浏览器和平铺手机，看看是否看起来像文本？。

Jquery Mobile按钮未显示文本值？
