优化 JavaScript 代码：使用对象存储属性值

可以通过使用一个对象来存储不同情况下的属性值，然后根据条件进行赋值，以减少重复的代码。\n\njavascript\nlet breadCrumbsObj = {\n provinceName: \"\",\n dishiCityName: \"\",\n dishiCityImgShowFlag: false,\n countyTownName: \"\",\n countyTownImgShowFlag: false\n};\n\nif (this.localUserShenfen == 3) {\n breadCrumbsObj.provinceName = localStorage.getItem(\"localUserOrgJc\");\n} else if (this.localUserShenfen == 4) {\n breadCrumbsObj.dishiCityName = localStorage.getItem(\"localUserOrgJc\");\n} else {\n breadCrumbsObj.countyTownName = localStorage.getItem(\"localUserOrgJc\");\n}\n\nthis.breadCrumbsObj = breadCrumbsObj;\n\n\n这样可以减少重复的代码，并且更易于阅读和维护。
