Is there a way to check if a workflow is completed using Javascript?

Question

I created a form that start a workflow automatically when an item is created, and I redirect to html page that shows a message like "Processing... please wait.", and I wait 3 seconds and so redirect to a page with results of the workflow.

Instead of wait 3 seconds, I want to create a javascript that check if the workflow is completed, then redirect to results page.

I am using SharePoint 2010 Foundation

Is there way?

I haven't tried this method, but I think it should work. If you use the Lists web service to query for the particular item, you should be able to retrieve the workflow status column and see it's value. It should give you In Progress/Complete. In your code, you'd just need to check that status and wait/recheck in a few seconds or redirect to your page based on the results.

Edit: I tried using SPServices and it does work:

$().SPServices({
    operation: "GetListItems",
    async: false,
    CAMLViewFields: "<ViewFields><FieldRef Name='Title' /><FieldRef Name='WFColumn' /></ViewFields>",
    listName: "MyList",
    completefunc: function (xData, Status) {
        $(xData.responseXML).SPFilterNode("z:row").each(function() {
            if ($(this).attr("ows_WFCol" === 5)){
                console.log("It's complete");
          }
        });
    }
});

You can use the Dom/debug in the browser(press F12) then find the 'name =" "' atribute of the column. Then use that name with Spservcies. For my example I trigger my wf by updating a column then returning a workflow status colmn value:

 function CopyStrategyDocuments(StrategyDocID, StrategyDocLocation){



                                $().SPServices({
                                        operation: 'UpdateListItems',
                                        listName: 'Case Attachments',
                                        ID: StrategyDocID,
                                        valuepairs: [['Copy_x002d_Document','Yes'],['Copy_x002d_To',StrategyDocLocation]],
                                                                        completefunc: function(xData, Status) {


                                              var test = $(xData.responseXML).SPFilterNode("z:row").attr("ows_CopyDocu");
                                               alert(test)
                                        //  

                                        }
                                });
