比对的数据:
targetlist=[ { "id": 1, "host": "https://test-api-crm-codemaster.codemao.cn/" }, { "id": 2, "host": "https://test-api-marketing.codemao.cn/" } ]
提交的数据:
values=
{
case_name: "1111",
group_id: 23,
methods: "get",
re_head: "1111",
re_path: "1111",
st_code: "111",
st_host: "https://test-api-crm-codemaster.codemao.cn/",
state: ""
}
需求:
提交的st_host 字符 找到 targetlist对应的id 替换
const newValues = {...values} // 解构values，将原form的values形成一个新的对象newValues
newValues.st_host =
this.hosts.find(t => t.id === Number(values.st_host)).host // 利用es6数组的find函数找到对应id的item，将该item的host赋值给st_host
红色那坨等于下面的写法:
let host = ''
this.hosts.forEach((item, index) => {
if (item.id === Number(values.st_host)) {
host = item.host
}
})
等于下面这坨
var inventory = [
{name: 'apples', quantity: 2},
{name: 'bananas', quantity: 0},
{name: 'cherries', quantity: 5}
];
function findCherries(fruit) {
return fruit.name === 'cherries';
}
console.log(inventory.find(findCherries));
