How to send JQuery function value to @html.actionlink method

[Bajrang]

HI
good morning,

I need to send JQuery Method's value which is giving names of checked check boxes of the grid to do some processing.

I have a button out of the WebGrid, which is used to do some processing for the selected rows of the webgrid.

I have written jquery method which is returning names of checked check box names but I am not able to pass these name to actionlink.

In simple I am not able to call jquery method in actionlink .


Jqury method:

function GetSelectedProdcut() {
        var arr = [];
        var i = 0;
        var str = '';
        $('input:checkbox[id=chk]').each(function () {
            if ($(this).is(':checked'))
                str = str + $(this).val() + ",";
            //arr[i++] = $(this).val();

        });
        $('#hid').val(str);
       
        return str;
    }

Action link :

@Html.ActionLink("Product", "DownloadZip", new { str=GetSelectedProdcut()});

Method in controller:
public void DownloadZip(string str)
{
// Here in str I need the check boxes values,
}


Thanks

You should assign a function call in your A tag, then change location.href to your ActionResult. Do not use void. You don't have to use an HTML helper because you don't really need your URL to go anywhere.

<a href='#' onclick='GetSelectedProdcut(); return false;'>Download Zip</a>

In your javascript function:

function GetSelectedProdcut() {
        var arr = [];
        var i = 0;
        var str = '';
        $('input:checkbox[id=chk]').each(function () {
            if ($(this).is(':checked'))
                str = str + $(this).val() + ",";
            //arr[i++] = $(this).val();

        });
        
        location.href = '/yourcontroller/DownloadZip/?str=' + str;

        return false;
    }

Your DownloadZip should be an ActionResult where you will return a FILE, not a view.

public ActionResult DownloadZip(string str)
{
    return File("PhysicalPathToYourFile", "application/octet-stream", "Filename.zip");
}
