问题使用lodash过滤包含字符串的对象数组

我有一个值，我需要返回属性中包含此值的对象。

var search='CPP@';
var results=_.filter(collection,{VAL:search});

我需要抓住所有压缩'CPP @'的对象，而不是等于。我已经准备好了 https://jsfiddle.net/licass/e87mxfqt/

提前致谢。

答案:

var collection=[
  {
    "DSP_MAQ": "Máquina 4",
    "VAL": "CPP@4@1900-01-01"
  },
  {
    "DSP_MAQ": "Máquina 5",
    "VAL": "CMIP@5@1900-01-01"
  },
  {
    "DSP_MAQ": "Máquina 6",
    "VAL": "CMIP@6@1900-01-01"
  },
  {
    "DSP_MAQ": "Máquina 7",
    "VAL": "CMIP@7@1900-01-01"
  },
  {
    "DSP_MAQ": "Máquina 8",

  {
    "DSP_MAQ": "Máquina 10",
    "VAL": "CMIP@10@1900-01-01"
  }
 
];
 var search='CPP@';
    var results=_.filter(collection,function(item){
    return item.VAL.indexOf(search)>-1;
    });
    console.log(results);

如果你添加一些解释会更好！ - Pritam Banerjee

var collection=[
  {
    "DSP_MAQ": "Máquina 4",
    "VAL": "CPP@4@1900-01-01"
  },
  {
    "DSP_MAQ": "Máquina 5",
    "VAL": "CMIP@5@1900-01-01"
  },
  {
    "DSP_MAQ": "Máquina 6",
    "VAL": "CMIP@6@1900-01-01"
  },
  {
    "DSP_MAQ": "Máquina 7",
    "VAL": "CMIP@7@1900-01-01"
  },
  {
    "DSP_MAQ": "Máquina 8",
    "VAL": "CPP@8@1900-01-01"
  },
  {
    "DSP_MAQ": "Máquina 9",
    "VAL": "CMIP@9@1900-01-01"
  },
  {
    "DSP_MAQ": "Máquina 10",
    "VAL": "CMIP@10@1900-01-01"
  }
 
];
 var search='CMIP@9@1900-01-01';
var filterList = collection.filter(function(item) {
 return item.VAL === search;
})
console.log(filterList)

使用javascirpt过滤器。
