Question

我无法删除随图像标签自动生成的span标签。

Asp.net代码：

if (!IsPostBack)
            {
                Page.Response.Cache.SetCacheability(HttpCacheability.NoCache);


                SiteManagementService siteMng = new SiteManagementService();
                LogedUserDTO logedUser = siteMng.GetLogedUserByUserId(Session["UserLoginID"].ToString().Trim());

                LabelUser.Text = logedUser.FullName + " | " + logedUser.Company.CompanyDesc;
                **LabelImage.Text = "<img  src=\"" + siteMng.GetUserImageUrl() + logedUser.ProfileImage + "\"  class='img-avatar'  />";**
                LabelDatetime.Text = DateTime.Now.ToString();
                Session["UserAccessLevel"] = logedUser.UserGroupId;
                Session["UserCompanyId"] = logedUser.CompanyId;

                RepeaterMenu.DataSource = siteMng.GetMenuByUserGroup(logedUser.UserGroupId);
                RepeaterMenu.DataBind();

                LabelMasterFooter.Text = "© 2013 " + ResourceData.CompanyName + ". All rights reserved.";

            }

前端代码：

<asp:Label ID="LabelImage" runat="server" ></asp:Label>

生成的HTML代码：

<span id="ContentPlaceHolderHeader_LabelImage"><img src="UploadedFiles/ProPicturs/Img_1711.JPG" class="img-avatar"></span>

我想要的代码仅仅是

<img src="UploadedFiles/ProPicturs/Img_1711.JPG" class="img-avatar">

如果只想使用图片标签，则asp.net中有一个Image标签

protected string image_tag; // add this var in your page class and set it as protected

...

if (!IsPostBack)
{
    Page.Response.Cache.SetCacheability(HttpCacheability.NoCache);


    SiteManagementService siteMng = new SiteManagementService();
    LogedUserDTO logedUser = siteMng.GetLogedUserByUserId(Session["UserLoginID"].ToString().Trim());

    LabelUser.Text = logedUser.FullName + " | " + logedUser.Company.CompanyDesc;
    image_tag = "<img  src=\"" + siteMng.GetUserImageUrl() + logedUser.ProfileImage + "\"  class='img-avatar'  />";
    LabelDatetime.Text = DateTime.Now.ToString();
    Session["UserAccessLevel"] = logedUser.UserGroupId;
    Session["UserCompanyId"] = logedUser.CompanyId;

    RepeaterMenu.DataSource = siteMng.GetMenuByUserGroup(logedUser.UserGroupId);
    RepeaterMenu.DataBind();

    LabelMasterFooter.Text = "© 2013 " + ResourceData.CompanyName + ". All rights reserved.";

}

您可以尝试在.aspx页面中使用。

<%= image_tag %>

代替

<asp:Label ID="LabelImage" runat="server" ></asp:Label>

Answer 2

标签控件将向页面添加HTML元素。作为div或span元素。所以这个

<asp:Label ID="Label1" runat="server" CssClass="MyLabel">
    Content...
</asp:Label>

成为这个

<span id="Label1" class="MyLabel">
    Content...
</span>

但是PlaceHolder不会生成它自己的html元素。所以下面的代码

<asp:PlaceHolder ID="PlaceHolder1" runat="server">
     Content...
</asp:PlaceHolder>

会生成

Content...

但是有一些缺点，因为PlaceHolder没有CssClass属性。

删除在asp.net文本标签中生成的Span标签
