How to Find If an Array Contains a Specific String in Javascript/Jquery?

How to find if an array contains a specific string in JavaScript/jQuery?

When working with JavaScript or jQuery, you may often come across the need to check if an array contains a specific string. Fortunately, there are multiple ways to achieve this. In this article, we will explore two common solutions to this problem.

Solution 1: Using the Array.includes() method

The Array.includes() method is a built-in JavaScript function that allows you to check if an array contains a specific element. In our case, we can use this method to check if an array contains a specific string.

Here’s an example code snippet that demonstrates how to use the Array.includes() method:

const array = ['apple', 'banana', 'orange'];

if (array.includes('banana')) {
  console.log('The array contains the string "banana"');
} else {
  console.log('The array does not contain the string "banana"');
}

The above code will output “The array contains the string ‘banana’” since the array includes the string ‘banana’.

Solution 2: Using the jQuery.inArray() method

If you are working with jQuery, you can use the jQuery.inArray() method to find if an array contains a specific string. This method returns the index of the element if found in the array, or -1 if not found.

Here’s an example code snippet that demonstrates how to use the jQuery.inArray() method:

const array = ['apple', 'banana', 'orange'];

if ($.inArray('banana', array) !== -1) {
  console.log('The array contains the string "banana"');
} else {
  console.log('The array does not contain the string "banana"');
}

Similar to the previous solution, the above code will also output “The array contains the string ‘banana’” since the array includes the string ‘banana’.

Now that you know two different ways to find if an array contains a specific string in JavaScript and jQuery, you can choose the one that best fits your needs and implement it in your code.

Happy coding!
