If you need to check if value exists in jquery array then you can do it using jquery inarray function. $.inArray will help you to find and check if value is exists or not.

$.inArray function will return the index of element. If element not exist in given array it will return -1. So, we can check it very simply weather a value exist in array or not.

You can see bellow simple example how you can check with if condition:

Example:

<!DOCTYPE html>

<html>

<head>

<title>Jquery check if value exists in Array Example - </title>

<script src="http://code.jquery.com/jquery-1.9.1.js" type="text/javascript"></script>

</head>

<body>

<script type="text/javascript">

var myArray = ['PHP', 'Laravel', 'Codeigniter'];

console.log($.inArray('Laravel', myArray));

if ($.inArray('Laravel', myArray) >= 0) {

console.log('Laravel is exist!');

}else {

console.log('Laravel does not exist!');

}

</script>

</body>

</html>

I hope it can help you...
