In my opinion it would be the best solution to wrap the variable in some kind of The To invoke an instance .NET method from JavaScript (JS): Pass the .NET instance by reference to JS by wrapping the instance in a DotNetObjectReference and calling Create on it. Can be array to try to resolve include from multiple directories. Any changes that you make to the arguments inside the function do not reflect the passing variables outside of the function. Ie, create the variable in the parent and pass it down to the child as a prop. See the JavaScript Guide for more information on JavaScript exceptions. I want to pass a variable which holds an img src to another page using javascript onClick() function.
