我想从JSON对象中得到first_name它有元素数组通过迭代，例如，如果我输入'Ron'它会显示为文本但由于某种原因，我不能显示为文本除非我发送响应this
playerName: nbaPlayer[0]
但是它只显示一个元素作为文本，因为其他元素不在响应
中服务器响应输入图片描述
这里是一个代码获取，我使用搜索栏从车把栏搜索first_name
const nbaForm = document.querySelector('form')
const search = document.querySelector('input')
const messageOne = document.querySelector('#player-1')
nbaForm.addEventListener('submit', (event) => {
event.preventDefault()
const playerSearch = search.value
messageOne.textContent = 'Loading...'
fetch('http://localhost:4000/nba').then((response) => {
response.json().then(nbaData => {
if (nbaData.playerName === playerSearch) {
messageOne.textContent = nbaData.playerName
} else {
messageOne.textContent = 'not found'
}
})
})
})
请求方法
app.get('/nba', (req,res) => {
networkManager.nbaPlayerData((data)=>{
/
var nbaPlayer = []
for(var i=0; i<data.data.length; i++){
nbaPlayer.push(data.data[i].first_name)
}
console.log(nbaPlayer)
res.send({
playerName: nbaPlayer
})
})
})
车把文件

试试这个
fetch('http://localhost:4000/nba').then((response) => {
response.json().then(nbaData => {
var index = nbaData.playerName.indexOf(playerSearch)
if (index !== -1) {
messageOne.textContent = nbaData.playerName[index]
} else {
messageOne.textContent = 'not found'
}
})
})
从
获取数组res.send({
playerName: nbaPlayer // nbaPlayer is array
})
但在取回中，你想从简单对象
中获取数据
