下面的警告消息来了。
Validation (XHTML 1.0 Transitional): Attribute 'data-limit' is not a valid attribute of element 'option'.
我也选择了此选项
"Tools -> Options -> Text Editor -> HTML(Web Forms) -> Validation -> XHTML5 (selected)
index.aspx页面中的以下代码。
<option value="<%: company.Uid %>" class="short" data-limit="52" title="<%: company.Country.Name + " " + "-" + " " + company.Name%>">
<%: company.Country.Name + " " + "-" + " " + company.Name%></option>
