ajax请求，进行ajax处理后端特殊字符串

//前端传入officeId的值，将office对应ip地址传入到 

function getinipaddress() {
            var officeId = document.getElementById("officeId").value;
            var isinheritipVal = $("input[name='isinheritip']:checked").val();
                if (isinheritipVal==1){
                    $.ajax({
                        url: "${ctx}/sys/office/getParentId",
                        contentType: "application/json; charset=utf-8",
                        data: {officeId: officeId},
                        dataType: 'json',
                        success: function (data) {
                            if(data['status'] == 'ok'){
                                $("#inipaddress").val(data.result);
                                $("#inipaddress").attr("disabled",true);
                            }
                        }
                    });
                }
                else if(isinheritipVal==0) {
                    $("#inipaddress").val("");
                    $('#inipaddress').attr("disabled", false);
                }
        }
