Based on the comments above, it sounds like this sequence of events is happening:

  1. User is on a page which contains this JavaScript code
  2. User clicks a link on that page to go to another page
  3. The other page needs to display data based on the value from this JavaScript code

If that's correct, then you have a number of options available to you. To be clear, what is the value in question? strcity?:

$('#term').attr("placeholder", strcity);
$('#term').attr("value", strcity);

If so, then when you set that value here you could also potentially set it on perhaps the query string for the link to the next page. Something like this:

$('#someLink').src = '@Url.Action("Index", "Restaurants")?city=' + strcity;

This would use a mix of pre-run server-side code for the root of the link, and client-side code to just append that one value to it. Then the controller method simply accepts city as a parameter:

public ActionResult Index(string city)
{
    // get your list of restaurants and return the view
}

There's no need for TempData in this, you're just sending the value directly to the controller action.

If for whatever reason you don't want to modify the src like that, you could perhaps instead send the value through a form invoked by the link. So instead of an ActionLink to the index action on the restaurants controller, you might have something like this:

@using(Html.BeginForm("Index", "Restaurants", FormMethod.Get))
{
    <a id="restaurantsLink" href="javascript:void(0);">Go to restaurants</a>
    <input type="hidden" name="city" />
}

And JavaScript code later:

$('#restaurantsLink').click(function () {
    $('form').submit();
});

You might need to more uniquely identify that form in the jQuery selector, particularly if there are (or could be) other forms on that page. Then in your original JavaScript code you would just set the value in the hidden input:

$('input[name=city]').val(strcity);

In this second case the controller action would still be the same as the first one, accepting a city string parameter.
