1.符合条件的键赋值为空

Object.keys(oShouldPaymentData.receiptDetail).forEach((key)=>{
            if(key != "id" || key != "businessId") {
              oShouldPaymentData.receiptDetail[key] = '';
            }
          })

2.将所有键赋值为空

objDemo = {
	a : '1111',
	b : '2222',
	c : '33333'

}

Object.keys(objDemo).forEach(key=>{objDemo[key]=''})


console.log(objDemo)
