显示或隐藏子div

嗨，大家可以有人请指导我如何隐藏另一个div标签内的div？我使用JavaScript ...这是我到目前为止有：显示或隐藏子div

function hideShowQuestionDivs() { 

    var drpQuestions = document.getElementById('<%= drpNumQuestions.ClientID %>'); 
    if (drpQuestions.selectedIndex == 0) { 
     document.getElementById('one').parentNode.removeChild; 
     document.getElementById('2').style.display = 'none'; 
     document.getElementById('3').style.display = 'none'; 
    } 

    if (drpQuestions.selectedIndex == 1) { 
     document.getElementById('2').style.display = 'none'; 
     document.getElementById('3').style.display = 'none'; 
    } 

    if (drpQuestions.selectedIndex == 2) { 
     document.getElementById('3').style.display = 'none'; 
    } 
}

这是HTML的一个例子：

<asp:UpdatePanel ID="upEntryScreen" runat="server"> 
     <ContentTemplate> 
      <div id="divEntryMain"> 
       <br class="style13" /> 
       <span class="style13"> 
       <tr> 
        <th> 
        </th> 
       </tr> 
       </span> 
       <asp:Label ID="lblCampaignType" runat="server" CssClass="style13" 
        Text="Campaign Type"></asp:Label> 
       <span class="style13"> 
       </th> 
       <th> 
       </th> 
       </span> 
       <uc:ROSDropDown ID="drpCampaignType" runat="server" CssClass="style13" 
        onchange="javascript:hideOrShowBuilderDiv()" Width="140"> 
       </uc:ROSDropDown> 
       <span class="style13"> 
       </th> 
       </tr> 
       <tr>

        </th> 
       </tr>

你也应该发布一些HTML。 – DanielB 2011-06-07 07:30:48

你能显示html标记吗？ – jimy 2011-06-07 07:31:22

我已编辑显示html ..谢谢 – johnnie 2011-06-07 07:34:58

这是你如何隐藏子DIV

$('#parentDivID > #childDivID').hide();

，这是你可以展示孩子的div

$('#parentDivID > #childDivID').show();

确保你的页面中包含了jquery脚本..

基本上你需要选择你需要隐藏/显示的元素，并且在jquery中你可以使用CSS选择器来做到这一点。然后调用它们上的.show（）或.hide（）方法
