Unterminated String Constant MVC4 Razor View Engine

Question

I am working on MVC4 Application (Razor engine). When ever I try to call a js function from a button, it says error :-

Unterminated string constant

However it does not give any compile time or runtime error and works fine.

But on view there it clearly says about above mentioned error:

why it is so?

Answer 1

The Razor parser is picky, and in some cases it doesn't correctly parse or color-code the syntax. Your code will work.

To fix the issue, you can format the code in a way that the parser will know exactly how to figure this out. Use parentheses around all Razor server-side code references:

<input type="button" id="btntest" value="Details"
     onclick="ABC('@(Item.TourApplicationID)', '@(Item.TourID)')" />

Edit: above may have only been working in VS 2013, with or without an update. (or not at all- I just remember it working.

Below should work, taken from MVC3 unterminated string constant syntax error:

<input type="button" id="btntest" value="Details"
     onclick="@("ABC('" & Item.TourApplicationID & "', '" & Item.TourID & "')")" />

(I think that's correct. Hard to tell without the color-coding.)

I prefer string.format, so that onclick would look more like:

onclick="@(String.Format("ABC('{0}', '{1}')", Item.TourApplicationID, Item.TourID) )"
