Run Workflow via JavaScript?

Can I launch a Workflow via JavaScript the same way I can launch a dialog i.e. via the URL?

example script:

function openDialogProcess(dialogId, entityName, objectId)
{
var url = Xrm.Page.context.getClientUrl() +
  "/cs/dialog/rundialog.aspx?DialogId=" +
  dialogId + "&EntityName=" +
  entityName + "&ObjectId=" +
  objectId;
window.open(url);
}
