+# 如何在二开中只修改脚本不修改模版
+
+可以在继承SimpleFormSetup时，不指定模版
+
+```vue
+<script>
+    // 注意，这里继承的是SimpleFormSetup，使用script setup写法的组件无法继承，必须使用特别的版本
+    import SimpleFormSetup from '/@/components/SimpleForm/src/SimpleFormSetup.vue';
+
+    export default {
+        mixins: [SimpleFormSetup],
+        setup(props, ctx) {
+            const ret = SimpleFormSetup.setup(props, ctx);
+
+            return {
+                ...ret
+            };
+        },
+        watch: {
+            formModel: {
+                handler: function(oldVal, newVal){
+                    console.log('表单被改了！' + Math.random());
+                    this.formModel.zheDie17153 = this.formModel.zhaGe15916 + this.formModel.zhaGe22645
+                },
+                deep: true
+            }
+        }
+    };
+</script>
+```
+这里可以通过对formModel的监控和修改完成计算、赋值操作。
