从客户端传递到控制器的Asp.Net MVC参数为null

Question

Javascript

I have a method as follows,

        function OpenRecord(id ,module ,screen) {
            var url = '@Url.Action("OpenRecord", "Management", new { id = "_id", module = "_module",screen = "_screen" })';
            url = url.replace("_id", encodeURIComponent(id));
            url = url.replace("_module", encodeURIComponent(module));
            url = url.replace("_screen", encodeURIComponent(screen));
            window.location.href = url;
        }

Controller

public ActionResult OpenRecord(string id, string module, string screen)
    {
        Int64 someID = Convert.ToInt64(id);


        /*some act**/

        return RedirectToAction(screen, module, new { id = someId});


    }

When I run this i get id and module but screen param is passed null . When i inspect client side on chrome dev tools, i see all the parameters on javascript method are filled and the final url in url variable as follows;

/Management/OpenRecord/112?module=Customer&screen=MUSTRTANML

I guess that amp&; entity spoils my controller to get the last param but i am not sure and i don't know how to solve this.

Thanks in advance.

Answer 1

Simply wrap your Url.Action in Html.Raw() . Or you can go with replacement approach further - url = url.replace("&", "&") . Whatever you like, personally I would proceed with Html.Raw

Answer 2

you need to construct your url string with values

var url = '@Url.Action("OpenRecord", "Management", new { id = "_id", module = "_module",screen = "_screen" })';

this is wrong, it should be

var url = '/Management/OpenRecord?id=' + _id + '&module='+ _module + '&screen='+ _screen;

the above will pass the values of the variables rather than names , you cannot execute Url.Action as part of JavaScript this is Razor code
