Javascript:将数组元素作为选项放入选择框

Question

我有一个数组，我希望数组内的每个值都作为选项显示在输入选择框中。这是我自己尝试过的:

<select>
<script language="javascript" type="text/javascript"> 

var cars = ["Saab", "Volvo", "BMW"];

for(cars)
{
    document.write("<option>"cars"</option>");
}
</script>
</select>

Answer 1

使用这个 javascript 应该是这样的

<select id="MySelectBox">
</select>

<script language="javascript" type="text/javascript"> 

var cars = ["Saab", "Volvo", "BMW"];

for (i=0; i<cars.length; i++) {
        option+= "<option value='"+cars[i]+"'>"+cars[i]+"</option>";
}
document.getElementById("MySelectBox").html= option;

</script>
