//1.格式化日期 start ---------------------------------------->
//time 日期字符串 type 从什么时候开始返回 year = 返回年月日 month = 返回月日..
//style 样式，比如 年-月-日 年.月.日
const getTime = function(time:string,type:string,style:Number){
  const date = new Date(time);
  const year = date.getFullYear();
  const month = date.getMonth() + 1;
  const day = date.getDate();

  //返回 年-月-日
  if(type == 'year'&& style == 1){
    return `${year}-${month}-${day}`;
  }
  //返回 年-月
  if(type == 'year'&& style == 2){
    return `${year}-${month}`;
  }
  //返回 年
  if(type == 'year'&& style == 3){
    return `${year}`;
  }
  //返回 月-日

  //返回 月.日

  //返回 日

//2.格式化标题长度 start ---------------------------------------->
//title 标题 length 长度
const getTitleLength = function(title:string,length:number){
  if(title.length >= length){
    return title.substring(0, length) + "...";
  }else{

//3.格式化跳转路径 start ---------------------------------------->
//3.1跳转到频道页面或者一级列表页
const getLinkPath = (item:any) => {
  if (item.children_count == 0) {
      return `/${item.aLIas_pinyin}/list-1.html`;
  } else {
      return `/${item.aLIas_pinyin}/index.html`;
  }
}
//3.2跳转到详情页
const getLinkPathDetail = (item:any) => {
  if (item.islink == 1) {
      return `${item.linkurl}`;
  } else {
      return `/${item.pinyin}/${item.id}.html`;
  }
}
//3.格式化跳转路径 end ---------------------------------------->


//4.获得路由路径 start ---------------------------------------->
const getRoutePath = (type:Number) => {
  const route = useRoute();
  //获得当前的完整路径
  const fullPath = route.path;
  //拆分，取出来中间这一段，然后提取数字部分
  const segments = fullPath.split('/');
  const targetSegmentOne = segments[1];
  const targetSegmentTwo = segments[2];

  if(type == 1){
    return targetSegmentOne;
  }
  if(type == 2){
    return targetSegmentTwo;
  }
}
