从api获取数据，但是id带有Hyphen -

Question

所以我想做的是在密码硬币之间得到实时价格，直到一些身份证明出现了破折号，问题才出现。

​

​

这是代码

var btcbnb, ethbnb, usdtbnb, usdcbnb, ltcbnb;
  var btcln, ethcln, usdtcln, usdccln, ltcln, bnbln ,bch;
  var liveprice11 = {
    "async": true,
    "scroosDomain": true,
    "url": "https://api.coingecko.com/api/v3/simple/price?ids=bitcoin%2Cethereum%2Cusd%2Clitecoin%2Cbinancecoin%2Cbinance-peg-bitcoin-cash&vs_currencies=bnb%2Clink%2Cusd",
  
    "method": "GET",
    "headers": {}
  }
  
  $.ajax(liveprice11).done(function (response){
    btcbnb = response.bitcoin.bnb;
    ethbnb = response.ethereum.bnb;
    usdtbnb = response.ethereum.bnb;
    usdcbnb = response.usd.bnb;
    ltcbnb = response.usd.bnb;
    // link
    btcln = response.bitcoin.link;
    ethcln = response.ethereum.link;
    usdtcln = response.usd.link;
    usdccln = response.usd.link;
    ltcln = response.litecoin.link;
    bnbln = response.binancecoin.link;
    bch = response.binance-peg-bitcoin-cash.usd;
    console.log(bch);
  });

这是有问题的线路

 bch = response.binance-peg-bitcoin-cash.usd;

真希望有人能帮忙，谢谢

正如您所发现的，JS不允许您访问具有这种破折号的对象成员的名称。

一个简单的解决办法是

bch = response['binance-peg-bitcoin-cash'].usd;
