ASP.NET MVC using ViewData in javascript

rated 0 times [ 197] [ 1] / answers: 1 / hits: 73939 / 13 Years ago, mon, may 2, 2011, 12:00:00

I am currently building a website in ASP.NET MVC. I am trying to access ViewData in javascript.

Is there any way that I can access a string value using javascript in a View that was stored in ViewData in a Controller Action. ( I am not able to figure out the right syntax ).

I wish to do something like..





var str = ViewData[Text];

I tried the following:

var str = <%=ViewData[Text] %>

but it didn't work.

Can someone please help.

Thanks.

Like this (Razor):

var str = @Html.Raw(Json.Encode(ViewData[Text]));

or (WebForms), using the JavaScriptSerializer (and after importing theproper namespace to your webform - System.Web.Script.Serialization):

var str = <%= new JavaScriptSerializer().Serialize(ViewData[Text])) %>;

And please don't use ViewData in an ASP.NET MVC application. Use view models and strongly typed views so that your code looks like this:

var str = <%= new JavaScriptSerializer().Serialize(Model.Text) %>;

This technique is even cooler as now you can JSON serialize the entire view model:

var model = <%= new JavaScriptSerializer().Serialize(Model) %>;

var str = model.Text;
