的Javascript賓果「自由」空間

Question

function populateN() { 
    var nNumbers = [31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45]; 
    var i = 0; 
    for (i = 0; i < 5; i++) { 
    var tempString = "r" + (i + 1) + "c3"; 
    var temp1 = nNumbers.length; 
    var temp2 = Math.floor(Math.random() * temp1); 
    var temp3 = nNumbers[temp2]; 
    document.getElementById(tempString).innerHTML = temp3; 
    nNumbers[temp2] = nNumbers[0]; 
    nNumbers.shift(); 
    } 
} 

你怎麼覆蓋表格單元格「R3C3」與「自由」

Answer 1

像這樣的字符串值？

document.getElementById("r3c3").innerHTML = "FREE";
