<option value="authors">Authors</option>
<option value="chemistry">Chemistry</option>
</select>
</body>
<script>
window.onload = initialise;
function initialise() {
var options = document.getElementsByTagName('option');
for (var i = 0; i < options.length; i++) {
options[i].addEventListener("click", getQuestion, false);
//console.log(i);
}
}
function getQuestion() {
console.log("getting question..");
}

推荐答案
我不知道为什么他们都不是绑定,但你不是寻找on change函数?所以你可以绑定到那个一次?
I don't know why they all aren't binding but aren't you look for the on change function? So you can just bind to that once?
//Untested
var Category = document.getElementsById('category');
Category.addEventListener("change", getQuestion, false);
此外,如果你不反对Jquery,你可能想看看它经常摆脱的跨浏览器问题。在Jquery中:
Also, If you're not against Jquery, you might want to look into it it often gets rid of cross-browser issues. In Jquery:
$('body').on('change', '#category', function() {
getQuestion($(this));
})
