推荐答案
请查看演示 - [Issue]在Div中显示DropDownList的所有值 [ ^ ]。
它可以满足您的需求。
只需修改showDiv（）函数，如...
Please check the Demo - [Issue] Show all values of DropDownList in Div[^].
It does what you need.
Just modify theshowDiv()function like...
function showDiv() {
var ddlSubCategory = document.getElementById('subCategory');
for (i = 0; i < ddlSubCategory.options.length; i++) {
document.getElementById('sidebar-left').innerHTML += ddlSubCategory.options[i].value + "<br/>";
}
}
