在网页中放置Bootstrap Dialog Model

Question

我在我的网站上使用了Bootstarp模式，但当我尝试用按钮点击这个模态时

<input type="image" name="ImageButton4" id="ImageButton4" class="bw" data-target="#pnlModal" data-toggle="modal" src="Images/note.png" onclick="javascript:return false;" style="width:15%;" />

  

它显示了这张照片的禁用模型！

这是我的模型CSS代码，它存在于bootstrap.cs`

中

 </div>
    <asp:Panel ID="pnlModal" runat="server" role="dialog" CssClass="modal fade">
        <asp:Panel ID="pnlInner" runat="server" CssClass="modal-dialog" >
            <asp:Panel ID="pnlContent" CssClass="modal-content" runat="server">
                <asp:Panel runat="server" class="modal-header">
                    <button type="button" class="close" data-dismiss="modal">
                        <span aria-hidden="true">&times;</span><span class="sr-only">Close</span>
                    </button>
                    <h4 class="modal-title">Write Your Note Now ! we'll save it in "D" partition </h4>
                </asp:Panel>
                <asp:panel runat="server" class="modal-body">
                  <asp:TextBox ID="NoteText"  TextMode="MultiLine" CssClass="form-control" Font-Size="Larger" Font-Bold="true" runat="server"></asp:TextBox>
                 </asp:panel>
                <asp:panel runat="server" class="modal-footer">
                    <asp:LinkButton  OnClick="Button1_Click1" ID="Button1" runat="server"  CssClass="btn btn-success"  >Write Now ! </asp:LinkButton>
                </asp:panel>
            </asp:Panel>
        </asp:Panel>
    </asp:Panel>

以及所有模态标记

Answer 1

显然，您的.modal元素位于 .modal-backdrop元素下。默认情况下，他们z-index'是

.modal-backdrop {
   z-index: 1040;
}
.modal {
   z-index: 1050;
}

您的代码/ CSS中的某些内容违反了此默认顺序。通过在 bootstrap.css和其他CSS声明之后添加上面的CSS 来重新引入z顺序。

<强>更新即可。您可以将其置于</head>之前或</body>之前的最后一件事，如果它不起作用：

<style type="text/css">
.modal-backdrop {
   z-index: 1040;
}
.modal {
   z-index: 1050;
}
</style>
