[JavaScript知识库]vue3 全局表单检验

想加一个全局表单的检验功能，每个 input 上面加又太麻烦
随便写一个方法

import { computed, reactive, watch } from "vue";

export function createForm<T>(obj: T): T {
    let o:any = reactive(obj as any);

    watch(o, () => {
        Reflect.ownKeys(o).forEach((k) => {
            let value = Reflect.get(o, k);
            if (value && typeof value === "string") {
                Reflect.set(o, k, value.toString().replace(/[^\w]/g, ""));
            }
        });
    });
    return o as T;
}

使用方法，在每次创建表单的时候调用这个函数，并创建一个 reactive 对象

<template></tempalte>
<script lang="ts" setup>
...
interface FormState{
    password: string;
    confirmPassword: string;
    email: string;
}


const formState = createForm<FormState>({
    password: "",
    confirmPassword: "",
    email: "",
});
...
</script>
