Vue2 将对象中的某个值变为true,其他值都为false

data() {
    return {
      showTool: {
        flag1: false,
        flag2: false,
        flag3: false,
        flag4: false,
        flag5: false,
        flag6: false,
        flag7: false,
      }
    }
  },
  methods: {
    changeByKey(obj, key, type) {
      if (type == 0) {
        // type为0时全部为false
        for (let i in obj) {
          obj[i] = false;
        }
      } else if (type == 1){
      	// type为1时全部为obj[key]=true,其他全为false
        for (let i in obj) {
          if (i == key) {
            obj[i] = true
          } else {

          }
        }
      } else if (type == 2){
      // type为2时全部为true
        for (let i in obj) {
          obj[i] = true;
        }
	  }
    },
