每次运行后更正当前状态

const product = ['Product 1', 'Product 2']

const res = []
for (let i = 0; i < product.length; i++) {
  res.push({
    product: product[i],
    url: 'price',
    state: false,
  }, {

    state: false,

}

function setState(res, state) {

  this.setState(res[i], false)
  console.log(`Set state to false for ${JSON.stringify(res[i])}`)
