I have an array:

let array = [
  'Hello 1» (Foo_Test-Editable)', 
  'Hello 2» (Foo_Test-Editable)', 
  'Hello 3»  (Foo_Test)', 
  'Foo_Test_4'
];

let searchKeyword = 'Foo_Test';
const result = array.filter(f => f.indexOf(searchKeyword) != -1);
console.log(result);

If you can change the keyword to a regex...

let array = [
    'Hello 1» (Foo_Test-Editable)', 
    'Hello 2» (Foo_Test-Editable)', 
    'Hello 3»  (Foo_Test)', 
    'Foo_Test_4'
  ];
  
  let searchKeyword = /Foo_Test[^-|_]/;
  const result = array.filter(f => searchKeyword.test(f));
  console.log(result);

JavaScript Array Filter: Filtering Array Elements Based on a Test , If you can change the keyword to a regex let array = [ 'Hello 1� (Foo_Test- Editable)', 'Hello 2� (Foo_Test-Editable)', 'Hello 3� (Foo_Test)',� var newArray = array.filter(function(item) { return condition; }); The item argument is a reference to the current element in the array as filter() checks it against the condition. This is useful for accessing properties, in the case of objects. If the current item passes the condition, it gets sent to the new array. Filtering an array of objects

Add the parentheses around "Foo_Test" to distinguish it.

let srch = "(Foo_Test)"

let arr = [
    "Hello 1» (Foo_Test-Editable)",
    "Hello 2» (Foo_Test-Editable)", 
    "Hello 3»  (Foo_Test)", 
    "FooText"
]

let srch = "(Foo_Test)"

const result = arr.filter( f => f.indexOf(srch)!= -1)

console.log(result)

Filter array based on the keyword, Use filter() on arrays to go through an array and return a new array with the elements that pass the filtering rules. The filter() method creates a new array with all the elements that pass the test implemented by the callback() function. Internally, the filter() method iterates over each element of the array and pass each element to the callback function. If the callback function returns true, it includes the element in the return array.

Actually your code is working , output was 3 array because all of them contained search value Foo_Test

(3) ["Hello 1» (Foo_Test-Editable)", "Hello 2» (Foo_Test-Editable)", "Hello 3»  (Foo_Test)"]

so add parentheses around (Foo_Test) to distinguish it from other, which will output specific value

(Foo_Test)

  • You are searching for Foo_Test and your code works, it returns all three lines because all three of them contain Foo_Test. Now, what you are doing wrong, can be two things. In order to get the desired output, you can either search for something more specific like (Foo_Test), or modify your code so it excludes, for instance, lines with Foo_Test-followed-by-another-word. You need to define precisely the goal and the rules.
  • @JeremyThille thanks for the response. I've updated my question
  • thanks man! It works! Thank you very much! You are awesome! Ninja man! Super!:)
  • sorry man, I can't do it. Thanks for your response. Maybe you have another suggestion?
  • @Learner what are your constraints?
  • array item should contain only Foo_Test, not Foo_Test+...
  • @Learner Foo_Test will always include the first three strings, bc they all have that substring in them
