超链接实现post方式提交

 var url = $("#contextPath").val() + "/fee-bill/queryBill";
    var objForm = document.createElement("form");
    objForm.action = url;
    objForm.method = "POST";
    objForm.target = "_blank";

    var objInput1 = document.createElement("input");
    objInput1.type = "text";
    objInput1.name = "refBillCode";
    objInput1.value = refBillCode;
    objForm.appendChild(objInput1);

    var objInput2 = document.createElement("input");
    objInput2.type = "text";
    objInput2.name = "billCode";
    objInput2.value = billCode;
    objForm.appendChild(objInput2);

    var objInput3 = document.createElement("input");
    objInput3.type = "text";
    objInput3.name = "abnormalCode";
    objInput3.value = abnormalCode;
    objForm.appendChild(objInput3);

    document.body.appendChild(objForm);
    objForm.submit();
