使用Underscore.js進行過濾

Question

我需要使用Underscore.js過濾上面的JSON

如何僅返回“余額”不同於0的項目

 { Currency: 'BCC', Balance: 0, Available: 0, Pending: 0, CryptoAddress: null }, { Currency: 'BLOCK', Balance: 0, Available: 0, Pending: 0, CryptoAddress: 'Bd24akqYDG97k6xmUqsnxAtrBRoXeffQhx' }, { Currency: 'BTC', Balance: 0.00153928, Available: 0.00153928, Pending: 0, CryptoAddress: '1BgWkjF1mwe1MZoCvxMmfSJ6fppNMD5GSx' }, { Currency: 'BTG', Balance: 2e-8, Available: 2e-8, Pending: 0, CryptoAddress: null } 

Answer 1

嘗試這個：

_.filter(yourList, function(obj){
   return obj.Balance !== 0
})

Answer 2

這是一個codepen示例：

})
