Question

我是js的新手，但非常渴望学习。我想做2＆＃34;因为＆＃34;循环。 1.将6次表的值存储到数组（timesTable），最多12x6。 2.将这些存储的值输出到控制台（例如，0 x 6 = 0,1 x 6 = 0，）。非常感谢。

<script>
    var timesTable = new Array();
    var multiplier = 6;

    timesTable[0] = 0 * multiplier;
    timesTable[1] = 1 * multiplier;
    timesTable[2] = 2 * multiplier;
    timesTable[3] = 3 * multiplier;
    timesTable[4] = 4 * multiplier;
    timesTable[5] = 5 * multiplier;




    console.log("0 x " + multiplier + " = " + timesTable[0]);
    console.log("1 x " + multiplier + " = " + timesTable[1]);
    console.log("2 x " + multiplier + " = " + timesTable[2]);
    console.log("3 x " + multiplier + " = " + timesTable[3]);
    console.log("4 x " + multiplier + " = " + timesTable[4]);
    console.log("5 x " + multiplier + " = " + timesTable[5]);


</script>

Answer 1

不需要2个循环，您可以在一个循环中执行此操作：

var upTo = 12;
for (var i=0; i<upTo; i++) {
    timesTable.push(i*6)
    console.log(i + " x " + multiplier + " = " + i*6);
}

但如果你真的需要2：

var upTo = 12;
for (var i=0; i<upTo; i++) {
    timesTable.push(i*6)
}

for (var i=0; i<upTo; i++) {
    console.log(i + " x " + multiplier + " = " + timesTable[i]);
}

Answer 2

您可以在一个for循环中轻松完成，而无需将数组存储在其中。

var multiplier = 6;

for (var i = 0; i < 13; i++) {
    console.log(i + ' x ' + multiplier + ' = ' + (i * multiplier));
}

这将打印6次表格至12 https://jsfiddle.net/o3k6feua/
