useForm的bug

[w2ichan]

declare function useForm(modelRef: Props, rulesRef?: Props, options?: { immediate?: boolean; deep?: boolean; validateOnRuleChange?: boolean; debounce?: DebounceSettings; }): { ....... };

function useForm(modelRef, rulesRef, options) { var initialModel = cloneDeep(modelRef); var validateInfos = {}; Object.keys(rulesRef).forEach(function (key) { validateInfos[key] = { autoLink: false, required: isRequired(rulesRef[key]) }; }); ...... }

rulesRef为非必填参数，但是useForm方法中，却没有判断rulesRef是否为undefined，直接进行Object.keys操作....这样会报错~

目前有解决办法

useForm(modelRef, reactive({}));

rulesRef必须为reactive对象，直接使用空对象会有警告，这是由于 watch(rulesRef, function () { if (options && options.validateOnRuleChange) { validate(); } }, { deep: true })

这一段代码导致，所以watch必须是一个reactive对象，
