<span class="text-danger">
@{
if (Model.uploadErrorMessage != null)
{
if (!string.IsNullOrEmpty(Model.uploadErrorMessage))
{
Model.uploadErrorMessage;
}
}
}
</span>
Given code above, how do I display Model.uploadErrorMessage inside <span> tag?
Currently it give me this error on Model.uploadErrorMessage:
Only assignment, call, increment, decrement, and new object expressions can be used as a statement
Put your span tag inside if statement
@{
if (Model.uploadErrorMessage != null)
{
if (!string.IsNullOrEmpty(Model.uploadErrorMessage))
{
<span class="text-danger">@Model.uploadErrorMessage</span>
}
}
}
All of those if statements are completely unnecessary anyway, you can simplify the entire thing to this:
<span class="text-danger">@Model.uploadErrorMessage</span>
if that embrace the span and not adding an empty DOM to the page when the message is null or empty:-)
span would be different, but it's possible the empty span is required due to some Javascript thing perhaps.use the "@"-symbol to write your variable value to the view:
for example:
<span>This is the error: @(Model.uploadErrorMessage)</span>
@Html.Raw(Model.uploadErrorMessage)
you can simply put @Model.uploadErrorMessage
Edit: XSS vulnerability fix, based on @DavidG's comment.
That's a bit dangerous
<text>Html.Raw(Model.uploadErrorMessage)</text>or just<text>@Model.uploadErrorMessage</text>.<span>@Model.uploadErrorMessage</span>ifstatement is made redundant by the inner one, and you can remove them both anyway - see my answer.
