我通过 cors 从 AJAX 获取 HTML 响应，响应是一个表格。每个类别都有其标题和子元素。标题名称变化很大，将来可能会发生变化。每个标题中的子元素几乎每天都在变化，但 DOM 结构不会。
有没有办法我可以摆脱这个 if 语句并用不是特定元素的代码替换它？选择我不知道的 DOM 元素的某种方式？

classifiedFilter: function( response ) {
var Classified = {
ClaAdministrative: [],
Paraeducator: [],
Clerical: [],
Custodial: [],
NonRep: [],
Maintenance: [],
ClaSubstitute: [],
Coaching: []
},
response = $(response).find("table tbody tr td").html();
$(response).find("#isHeadType").remove();
$(response).find("font:contains(Open to all)").parent().parent().remove();
//Filter each span title and classify sub items
$(response).find("span").parents("tr").each( function() {
//Find categories and separate by class
var rowtext = $(this).find("span").text(),
position = "";
position = rowtext.replace(/-/gi, "").replace(/\s/g, "");
$(this).nextAll("tr").addClass(position);
//Push content into Classified
((position === "Administrative") ? $(this).nextUntil(".Paraeducator").each( function() {
Classified.ClaAdministrative.push( $.trim( "<tr>" + $(this).html() + "</tr>" ) );
}) :
