1、使用ref获取组件

<base-form ref="baseFormComponents"></base-form>

const baseFormComponents = ref(null)

2、defineExpose出需要使用的方法

const submit = (e) => {form1.value.validate(valid => {if (valid) {uni.showToast({title: "验证通过",icon: 'none'});console.log('验证通过');} else {console.log('验证失败');}});}defineExpose({submit})

3、使用

const formSubmit = () => {if (baseFormComponents.value) {baseFormComponents.value.submit()} else {console.log("baseFormComponents is undefined.");}};
