How to change a model property from a javascript function inside a view?

Question

Is there any way to alter my Model properties from a javascript function inside a view?

Specifically, I have an edit view and need to access a string property value with

function SomeJSFunction() {
var somevar = '<%=Model.Property %>';
...

then do some changes on somevar and set the model property to the changed string. I'm doing a submit at this point, so it's not a question of dealing with the display, just need to alter the model from inside the function before I submit. I know I could pass the string as a parameter and deal with it inside the controller but it just doesn't cut it as I really need to be done with it in the view. Appreciate any help!

You can't do this using javascript. The model is instantiated by the controller and passed to the view. If you want to modify some properties you will need to perform a request to a controller action and send the new values. This could be done either using a standard form or AJAX request.
