For anyone looking for another answer. I used this method because I had to first search for the dynamically created select list.
对于任何寻找另一个答案的人。我使用这种方法是因为我必须首先搜索动态创建的选择列表。
var dropdown = document.getElementsByTagName("select");
for (i=0; i<dropdown.length; i++) {
if (dropdown[i].title == "Component") {
dropdown[i].onchange = changeApproverCC;
}
}
