JS過濾后臺獲取的原始數(shù)據(jù)

es6采用樓上的方法；
es5寫法：

nArr = json.filter(function(item){
    return item.FromStation === '北京';
});

不過建議做下簡單的方法封裝，將過濾關(guān)鍵詞作為變量傳入方便隨時更換關(guān)鍵詞

function filterKey(key){
    return json.filter(function(item){
        return item.FromStation === key;
    })
}

`var sourceData = [
{"CostTime": "310", "FromStation": "上海"},
{"CostTime": "336", "FromStation": "北京"},
{"CostTime": "310", "FromStation": "上海"},
{"CostTime": "336", "FromStation": "北京"},
{"CostTime": "310", "FromStation": "上海"},
{"CostTime": "336", "FromStation": "北京"},
{"CostTime": "310", "FromStation": "上海"},
{"CostTime": "336", "FromStation": "北京"},
{"CostTime": "310", "FromStation": "上海"},
{"CostTime": "310", "FromStation": "上海"},
{"CostTime": "336", "FromStation": "北京"}
];
var currentData = sourceData.filter(x => {

return x.FromStation === '北京';

});
console.log(currentData); // 你要的結(jié)果
`

nArr = json.filter((item) => {
   return item.FromStation == '北京'
})
