Find value of string in Array

I've been working on this simple script for a few hours now and have hit a wall. I have an Array comprised of JSON values. When a user searches for a string and clicks the button, the script checks the string against the values stored in the Array. The section I'm stuck on is the conditional, which always returns no match - even if I enter a string which I know is in the JSON file. Code below. Any guidance/pointers would be greatly appreciated. Thanks for your help! Mark. $('#validate-info').on('click', function(){ // Get data, initiate callback $.getJSON('memberships.json', validateMembership); // Execute callback function function validateMembership(data) { // Capture entered value var userVal = document.getElementById('form-data').value; console.log(userVal); var infoTxt = ''; // Push all items into an Array var infoArray = []; $.each(data, function(member, memberInfo) { infoTxt += '<p><strong>Name:</strong> ' + memberInfo.name + '<br />'; infoTxt += '<strong>Membership No.:</strong> ' + memberInfo.number + '<br />'; infoTxt += '<strong>Expiry Date:</strong> ' + memberInfo.expiry + '</p>'; infoArray.push({ name: memberInfo.name, number: memberInfo.number, expiry: memberInfo.expiry }); }); if ($.inArray(userVal, infoArray) > -1 ) { // the value is in the array $('#response').html('<p style="color: green;">In the array</p>'); } else { $('#response').html('<p style="color: red;">Sorry, no matches.</p>'); } } });
