我正在處理以下代碼。為什么我會收到此錯誤："message": "Uncaught TypeError: Cannot read property '0' of undefined",同時從循環中獲取結果？var ifclus = [["-9.00", "-6.50"], ["-6.00", "+6.00"]];for (var i = 0; i <= ifclus.length; i++) { var start = parseFloat(ifclus[i][0]).toFixed(2); var end = parseFloat(ifclus[i][1]).toFixed(2); console.log(start)}<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
即使在訪問數據后也會在循環中出現未定義的錯誤
