How to filter javascript array using substring search for key and value pair-CodePudding

in the below array i want to filter out records, that match the substring "11/2022" for key StartTime

[
  {
    StartTime: '17/10/2022 14:45',
    Duration: '000:00:44:32',
  },
  {
    StartTime: '17/11/2022 14:45',
    Duration: '000:00:44:30',
 
  },
  {
    StartTime: '18/11/2022 14:45',
    Duration: '000:00:44:30',
 
  },  
   {
    StartTime: '17/12/2022 14:45',
    Duration: '000:00:44:30',
 
  }
]

expected output:

[
   {
    StartTime: '17/11/2022 14:45',
    Duration: '000:00:44:30',
 
  },
   {
    StartTime: '18/11/2022 14:45',
    Duration: '000:00:44:30',
 
  }
   
]

CodePudding user response：

you can use the includes function like this

[
    { StartTime: "17/10/2022 14:45", Duration: "000:00:44:32" },
    { StartTime: "17/11/2022 14:45", Duration: "000:00:44:30" },
    { StartTime: "18/11/2022 14:45", Duration: "000:00:44:30" },
    { StartTime: "17/12/2022 14:45", Duration: "000:00:44:30" },
  ].filter((item) => item.StartTime.includes("11/2022"));

CodePudding user response：

You can use filter() to loop through the array of objects, and for each object item, check whether the StartTime includes() any of the search keyword substring.

const array = [{
    StartTime: '17/10/2022 14:45',
    Duration: '000:00:44:32',
  }, {
    StartTime: '17/11/2022 14:45',
    Duration: '000:00:44:30',

  }, {
    StartTime: '18/11/2022 14:45',
    Duration: '000:00:44:30',

  },
  {
    StartTime: '17/12/2022 14:45',
    Duration: '000:00:44:30',

  }
];

const searchKey = '11/2022';
const filteredArray = array.filter(item => item.StartTime.includes(searchKey));

console.log(filteredArray);

Hope it helps!

Just using Array.filter() can do it

let data = [
  {
    StartTime: '17/10/2022 14:45',
    Duration: '000:00:44:32',
  },
  {
    StartTime: '17/11/2022 14:45',
    Duration: '000:00:44:30',
 
  },
  {
    StartTime: '18/11/2022 14:45',
    Duration: '000:00:44:30',
 
  },  
   {
    StartTime: '17/12/2022 14:45',
    Duration: '000:00:44:30',
 
  }
]

let result = data.filter(d => d.StartTime.includes('/11/2022'))
console.log(result)

const arr = [
    { StartTime: '17/10/2022 14:45', Duration: '000:00:44:32', }, 
    { StartTime: '17/11/2022 14:45', Duration: '000:00:44:30', }, 
    { StartTime: '18/11/2022 14:45', Duration: '000:00:44:30', },
    { StartTime: '17/12/2022 14:45', Duration: '000:00:44:30',}
]

const newArr = arr.filter(elem => elem.StartTime.match("11/2022"))

CodePudding user response：

You can use .filter() and .includes():

const input = [
    { StartTime: '17/10/2022 14:45', Duration: '000:00:44:32', },
    { StartTime: '17/11/2022 14:45', Duration: '000:00:44:30', },
    { StartTime: '18/11/2022 14:45', Duration: '000:00:44:30', },
    { StartTime: '17/12/2022 14:45', Duration: '000:00:44:30', }
];

const result = input.filter(element => {
    return element.StartTime.includes("11/2022");
});

console.log(result);
