"Debunking the Misconceptions of Syntax Errors in Visual

Every time I utilize the @ sign in a Razor page, like this:

<script type="text/javascript">
if( @(ProjectName.NameSpace.booleanVariable) ) {
    doStuff();
}
</script>

I end up with syntax error alerts all over, which disappear after conversion to HTML:

<script type="text/javascript">
if(True) {
    doStuff();
}
</script>

This is just one example, but it occurs in other situations too. If needed, I can provide more examples. Although I couldn't find a solution on other stackoverflow posts, I assume there must be an answer to such a basic question. Links to relevant questions are welcome.

Edit: I should clarify that the examples are JS inside a Razor Page.

Question: How can I stop these syntax error notifications so that I can easily spot and handle actual syntax errors?

Answer №1

Shoutout to Daniel Sanchez for the solution.

I managed to disable the notifications by using this method:

'@ProjectName.NameSpace.booleanVariable'

However, my colleague Steve advised against this approach and suggested storing the value in HTML for JS access.

<input type="hidden" id="booleanVariable" value="@ProjectName.NameSpace.booleanVariable" />

Appreciate the input!

Answer №2

Using the keyword "True" in JavaScript is not valid.

<script type="text/javascript>
if( Boolean(@Html.Raw(Json.Encode(ProjectName.NameSpace.booleanVariable))) ) {
    doStuff();
}
</script>

The use of Boolean() function in JavaScript helps avoid Razor Warning messages.

To convert booleanVariable to either "true" or "false", you can use (ProjectName.NameSpace.booleanVariable ? "true" : "false")

It seems like what you are looking for is:

@if(ProjectName.NameSpace.booleanVariable) {
{<script type="text/javascript">
    doStuff();
</script>}
}
