过滤键值后如何从JSON追加

Question

我有一个JSON，其中我使用jQuery $.each函数将数据追加到表中。 我做一个if语句来检查一个值是否匹配字符串。

在我的最后一个表格列中，我需要从另一个文本过滤器获取数据。 因此，如果数据值与我的过滤器匹配，则将其附加为最后一个td

dataset = [
  "river": {
    "year": "2016",
    "name": "Silver Creek",
    "series": "Caught fish",
    "weight": "100 kg",

  },
  "river": {
    "year": "2016",
    "name": "Silver Creek",
    "series": "Released fish",
    "weight": "60 kg"
  }
];

$(dataset).each(function(i, data){

  if (data.year === "2016" && data.series === "Caught fish") {
    $('tbody').append('<tr class="river"><td>' + this.year + '</td><td>' + this.name + </td><td>' + this.weight + </td></tr>')
  } if (data.year === "2016" && data.series === "Released fish") {
    $('tr.river').append('<td>' + this.weight + '</td>')
  }

});

上面的代码不做，但是我想要，但是可能是我要实现的提示。

我需要作为表格行：

YEAR | NAME         | CAUGHT | RELEASED
2016 | Silver Creek | 100 kg | 60 kg

有什么建议么？ 我可以根据$.each函数外部的数据集构建一个新变量吗？

对释放的鱼使用：contains选择器，查看表中是否已存在年份和水体：

 var dataset = [ {"year": "2015","name": "Cedar Creek","series": "Caught fish","weight": "90 kg"}, {"year": "2016","name": "Silver Creek","series": "Caught fish","weight": "60 kg"}, {"year": "2015","name": "Cedar Creek","series": "Released fish","weight": "40 kg"}, {"year": "2016","name": "Silver Creek","series": "Released fish","weight": "60 kg"} ]; dataset.forEach(function(data) { if(data.series === 'Caught fish') { $('tbody').append('<tr class="river"><td>' + data.year + '<td>' + data.name + '<td>' + data.weight); } else { $('tr:contains(' + (data.year + data.name) + ')').append('<td>' + data.weight); } }); 

 tr > * {border: 1px solid #ddd;}
