我从AJAX获取了一个关于cors的HTML响应，响应是一个表。每个类别都有其标题和子元素。标题名称变化很大，将来很可能会改变。每个标题中的子元素几乎每天都在变化，但DOM结构却没有。
有没有办法可以摆脱这个if语句并将其替换为非元素特定的代码？选择我不知道的DOM元素的一些方法？

var Classified = {

response = $(response).find("table tbody tr td").html();
$(response).find("#isHeadType").remove();
$(response).find("font:contains(Open to all)").parent().parent().remove();

这似乎等同于您当前代码的核心：
$(this).each( function() {
Classified[position].push( $.trim( "<tr>" + $(this).html() + "</tr>" ) );
});
[编辑]我没看到你声明数组的位置，你可能真的需要这个：
$(this).each( function() {
Classified[position]=Classified[position]||[];
Classified[position].push( $.trim( "<tr>" + $(this).html() + "</tr>" ) );
});
[更新]根据评论，此循环会在达到某个范围时更新位置：
var position = "";
$(response).find("tr").each( function() {
var currentTR=$(this);
// catch span if any
var rowtext = currentTR.find("span").text().replace(/-/gi, "").replace(/\s/g, "");
if (rowtext) {
position = rowtext;
Classified[position]=[];
}
// Collect rows
Classified[position].push( "<tr>" + $.trim($(this).html()) + "</tr>" );
});

我认为，你可以在find函数中使用CSS类名而不是标记名。
