Generating an action URL in JavaScript for ASP.NET MVC

Question

I\'m trying to redirect to another page by calling an action in controller with a specific parameter. I\'m trying to use this line:

window.open(\'<%= Url.         


        

Answer 1

Could you do

window.open('/report/survey/' + selectedRow);

instead where selected row I assume is the id? The routing should pick this up fine.

or use getJSON

Perhaps you could use JSONResult instead. Wherever the window.open should be call a method instead i.e. OpenSurveyWindow(id);

then add some jquery similar to below

function OpenSurveyWindow(id){
      $.getJSON("/report/survey/" + id, null, function(data) {
          window.open(data);
     });
}

now in your controller

public JsonResult Survey(int id)
{
    return Json(GetMyUrlMethod(id));
}

That code isnt syntactically perfect but something along those lines should work

Answer 2

I usually declare a javascript variable in the section to hold the root of my website.

<%="<script type=\"text/javascript\">var rootPath = '"
    + Url.Content("~/") + "';</script>" %>

To solve your problem I would simply do

window.open(rootPath + "report/survey/" + selectedRow);

Answer 3

If selectedRow is a client-side variable, it won't work. You have to use @Israfel implementation to link. This is because the server-side runs before the client-side variable even exists.

If selectedRow is a server-side variable within the view, change to this:

window.open('<%= Url.Action("Report", "Survey", new { id = selectedRow } ) %>');

This is because the id will infer the selectedRow variable type, or you could convert to string with ToString() method (as long as it's not null).
