You can use filter() rather than using map() operator to exclude RuleAutoIDs. Make sure whenever the input value changes searchTerm gets updated. Finally, you can use to toLowerCase() and includes() to find substring matches in lowercase. Refer to the code below: const rows = [{ RuleAutoID: 1, name: John Doe , age: 30 }, { RuleAutoID: 2, name: Jane Smith , age: 25 }, { RuleAutoID: 3, name: Mark Johnson , age: 35 } ]; const whiteList = [2]; function displayFilteredData(filteredData) { const tbody = document.getElementById( filteredData ); tbody.innerHTML = ; filteredData.forEach(row => { const tr = document.createElement( tr ); tr.innerHTML = `${row.RuleAutoID}${row.name}${row.age}`; tbody.appendChild(tr); }); } function setWhiteList() { const whiteListInput = document.getElementById( whiteList ).value; whiteList = whiteListInput.split( , ).map(id => parseInt(id.trim())).filter(id => !isNaN(id)); console.log( whiteList , whiteList); } function setWhiteList(filteredData) { const tbody = document.getElementById( filteredData ); tbody.innerHTML = ; filteredData.forEach(row => { const tr = document.createElement( tr ); tr.innerHTML = `${row.RuleAutoID}${row.name}${row.age}`; tbody.appendChild(tr); }); } function filterData() { const searchTerm = document.getElementById( searchTerm ).value.toLowerCase(); console.log( searchTerm , searchTerm); const filteredRows = rows.filter(row => !whiteList.includes(row.RuleAutoID)); console.log( filteredRows , filteredRows); const filteredData = filteredRows.filter(row => { const values = Object.values(row).filter(val => val !== null && val !== undefined && val !== ); console.log( values for row , row, values); return values.some(val => { console.log( checking value , val, against searchTerm , searchTerm); return typeof val === string && val.toLowerCase().includes(searchTerm); }); }); console.log( filteredData , filteredData); displayFilteredData(filteredData); } document.getElementById( filterButton ).addEventListener( click , filterData); displayFilteredData(rows.filter(row => !whiteList.includes(row.RuleAutoID))); .table { width: 100%; border-collapse: collapse; } .table th, .table td { border: 1px solid black; padding: 8px; text-align: left; }
