You also can do the Saurabh Chauhan response but without add the dinamic element to body This solution is all dinamic solution.

    var myform = document.createElement("form");
    myform.action = "myForm.aspx";
    myform.method = "post";


    product = document.createElement("input");
    product.value = "value";
    product.name = "name";

    myform.appendChild(product);
    myform.submit();
