Javascript:如何用循环输出多个数组？

Question

请帮忙。我只是新来的。我一直在尝试通过循环输出 2 组数组，但我似乎无法弄清楚。

这是我的代码:

<script>
cars=["BMW","Volvo","Saab","Ford"];
type=["Sports","Luxury","Premium","Economy"];
var i=0;
var a=0;
while (cars[i])
{
document.write(cars[i] + " - " + type[a]"<br/>");
i++;
}
</script>

我想要的结果是:

BMW - Sports
Volvo - Luxury
Saab - Premium
Ford - Economy

提前致谢!

由于您要打印的条目在数组中的相同索引处，只需在两者中使用 i(并在 type 之后添加他缺少的 + [i]):

document.write(cars[i] + " - " + type[i] + "<br/>");
// Here ------------------------------^  ^-- this was the missing +
