How to access javascript variable within @URL.Action()
In the same vein as Brian Mains's answer, you could format your url string instead of replacing -1 with your variable, that is if like me, you judge it is better to read. The following answer assumes that you've modified String
's prototype as suggested in this answer:
var url = unescape('@Url.Action("download file", "download", new { id = "{0}" })').format(myjavascriptID);
The unescape
call is necessary if you want to decode your {0}
. I like this alternative, because it makes it easier to have multiple parameters from JS variables. For instance:
var url = unescape('@Html.Raw(Url.Action("Action", "Controller", new { id = "{0}", name = "{1}" }))').format(myID, myName);
I added Html.Raw
in my second example in order to avoid having &
in the url string.
You can pass in the variables to any link as shown below...
var url = '@Html.Raw(@Url.Action("MethodName", "ControllerName"))' + '?id = ' + myjavascriptID
You can't. JavaScript doesn't execute when generating the action URL. What you can do, is do something like this:
function name(myjavascriptID) {
var link = '@Url.Action("download file", "download", new { id = "-1" })';
link = link.replace("-1", myjavascriptID);
jQuery("#list_d").jqGrid('setGridParam', { url: link, page: 1 });
}
I do something fairly similar, but less verbose:
var myUrl = '@Url.Action("Solution","Partner")/' + myjavascriptID;
$.ajax.load(myUrl); // or whatever
We can do this because of routing, and ultimately Url.Action with route dictionary parameters translates into a URI that looks like:
http://localhost:41215/Partner/Solution?myJavascriptID=7
Just a second choice, because as a wise old man once said "It is our choices, Harry, that show what we truly are, far more than our abilities."
