使用if和else来做判断，但是这段代码真的太冗余了，求帮忙优化一下

            }
        }

这是我写的一段代码，使用大量了if和esle，但是我自己感觉无法优化

不用es6的情况下，如何才能优化？

Answer 1

var mp = ['未婚单身无目标', '未婚单身有目标', '未婚有对象交往']
fieldFinancing[i].innerHTML = mp[strObj[i]['marriage']] || '婚姻状况：未知'

Answer 2

if else 那一大段可以换成switch

Answer 3

把选项封装成数组或对象

Answer 4

使用对象的键值对：

a = {
    1: "未婚单身无目标",
    2: "...",
}
b = a[strObj[i]['marriage']] || '婚姻状况：未知'

Answer 5

仅提供思路 下面为函数内容

            var get = document.getElementsByClassName;
            if (!get) {
                return;
            }
            get = get.bind(document);
            var personEducation = [
                "学历：高中以下",
                "学历：高中",
                "学历：大专",
                "学历：本科",
                "学历：硕士",
                "学历：博士",
                "学历：博士后"
            ],  fieldFinancing = [
                "婚姻状况：未知",
                "未婚单身无目标",
                "未婚单身有目标",
                "未婚有对象交往",
                "未婚有对象谈婚论嫁中",
                "离异没孩子找对象",
                "离异有孩子找对象",
                "离异有孩子不找对象",
                "订婚",
                "已婚"
            ];            
            for(var i = 0; i< listShow; i++ ) {
                var o = strObj[i],
                    _get = (function(i){
                        return function(name){
                            return get(name)[i] || {};
                        }
                    })(i);
                if (!o) {
                    console.warn('strObj[', i, ']', 'is undefined');
                    continue;
                }
                _get('sojob-item-main').parentNode.style.display = "block";
                _get('title').innerHTML = "<a href='article_detail.html?id="+o.id+"&userID="+o.uid+"'>"+o.title+"</a>";
                _get('author').innerHTML = o.author.substr(0,1) + (o.sex === '男' ? "先生" : "女生");
                _get('temptation').innerHTML = o.birthday ? "出生月份：" + o.birthday.substr(0,4) + "年" : "本人没有提供出生日期";
                _get('publishTime').innerHTML = o.dateline ? "发布时间：" + o.dateline : "未知";                
                _get('fieldFinancing').innerHTML = fieldFinancing[o.marriage] || "婚姻状况：未知";
                _get('personEducation').innerHTML = personEducation[o.education] || "学历：未知";
                _get('personOccupation').innerHTML = o.occupation || "未知";
                _get("personSalary").innerHTML = o.salary + "元/月";
            }

Answer 6

提供个思路

const actions = new Map([
  ['guest_1', ()=>{/*do sth*/}],
  ['guest_2', ()=>{/*do sth*/}],
  ['master_1', ()=>{/*do sth*/}],
  ['master_2', ()=>{/*do sth*/}],
  ['default', ()=>{/*do sth*/}],
])
const onButtonClick = (identity,status)=>{
  let action = actions.get(`${identity}_${status}`) || actions.get('default')
  action.call(this)
}
