我有一个看起来像的选择列表：
<select id="billing:region_id">
<option value="1"> Alabama </option>
<option value="2"> Arizona </option>
etc....
</select>
我试图遍历选项元素并将其相应的国家/地区代码作为id附加到元素上，但是当我像这样循环时，它会以未定义的形式返回：
jQuery("#billing\\:region_id option").each(function(k,v){
v.id = countryRegions['US'][Number(v.value)]['code'];
});
并且这些都不起作用
v.id = countryRegions['US'][Number(v.value)]['code'];
v.id = countryRegions['US'][Number(v.value)].code;
v.id = countryRegions.US[Number(v.value)]['code'];
但是当我说
时 v.id = countryRegions['US'][1]['code'];
这很好用，但是每个选项元素都会获得第一个目标代码。
我在这里做错了什么？
答案 0 :(得分：1)
在尝试使用之前，先检查数组中是否存在该值。
jQuery("#billing\\:region_id option").each(function(k,v){
if (countryRegion.US[v.value]) {
v.id = countryRegion.US[v.value].code;
}
});
