jquery给下拉框加子元素还可以这么写

   function getHospital() {
        $.ajax({
            url: '/hospital/list',
            type: 'POST',
            data: {},
            dataType: 'json',
            success: function (data) {
                if (data.status == '0') {
                    for (var i = 0; i < data.result.length; i++) {
                        var op = document.createElement("option");
                        op.text = data.result[i].hospitalName;
                        op.value = data.result[i].id;
                        document.getElementById("hospitalId").appendChild(op);
                        console.log(op)
                    }
                    layui.form.render();
                }
            }
        });
    }
