大家好，有人可以指导我如何隐藏另一个div标签内的div吗？ 我正在使用javascript ...这是我到目前为止所拥有的：
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">

<span class="style13">

答案 0 :(得分：0)
这是隐藏子div的方法
$('#parentDivID > #childDivID').hide();
这就是你如何展示子div
$('#parentDivID > #childDivID').show();
确保页面中包含jquery脚本..
基本上你需要选择你需要隐藏/显示的元素，而在jquery中你可以使用CSS选择器来完成。然后在它们上调用.show（）或.hide（）方法
