MVC: Use string variables of a view as parameter to a javascript function call

Question

How can I call a javascript function within a view(cshtml) and pass some string variables (defined in the view)to be used as parameters for the function call?

Say the function javascriptFunction uses 2 parameter. I will usually call it as

JavaScript

javascriptFunction('param1', 'param2')

But now I want to pass it some variables.

HTML

string y = "this is a string"
string x = "another"
javascriptFunction(y, x)

I have tried

JavaScript

javascriptFunction(@y, @x)

JavaScript

javascriptFunction('@y', '@x')

but these do not work

You need to pass the values in through a model, then @Model.X and @Model.Y will work. Where do x and y come from ? If they are javascript variables, then remove the @, which tells the compiler to use Razor, when you want local values.

x and y are variables derived in my view. I tried creating passing the values to the model and calling @Model.X but got the same error. It is a syntax error.

Perhaps if you told us what the error is ? And the actual code that creates them and where it lives ?

Member 8044586 8-Jan-13 17:51pm

The code is <input type="button" önclick="javascript: function('param1', @Model.temp);" value="Test" />. The error simply says: Syntax error with red markings before the @symbol and after closing the parentheses. So the markings surround @Model.temp)

You do need quotes. '@Model.temp'. The value will get rendered without quotes. This is a run time error ?

Also, as you have quotes, param1 will be passed as "param1", not the value in a param named that.

when I have it as <input type="button" önclick="javascript: function('param1', '@Model.temp');" value="Test" />, i get the error: Unterminated string constant Expected ')' with with red markings before the @symbol; and the quote before the close of the parentheses generates another error: Unterminated string constant

Edit your post to show your whole page so we can see what is going on.

I would also suggest trying to make your click event call a function that you define further down on the page
