for..in loops iterate over the entire prototype chain, which is virtually never what you want.
意思是使用for..in会遍历整个原型链，这样不是很好的实现方法，推荐使用Object.keys
formRules: { name: true, cardType: true, certificateNo: true }, formData: { name: ‘‘, certificateType: ‘‘, certificateNo: ‘‘ }
for (const key in this.formData) { if (!this.formData[key]) { this.formRules[key] = false; valid = false } if (this.formData[key]) this.formRules[key] = true }
Object.keys(this.formData).forEach(key => { if (!this.formData[key]) { this.formRules[key] = false; valid = false } if (this.formData[key]) this.formRules[key] = true })
for..in loops iterate over the entire prototype chain, which is virtually never what you want.
