if the current page is under  / , use  < router-link: to= "{path:"/",query: {category_id:item.id}}" > jump < / router-link >  to jump. In fact, the page has no jump effect, can it be processed as similar to the jump effect between different routes? 
 as shown in figure 
  
 
  Article  is under  / , and under  Category  is under  /? category_id=n . I hope you can jump by clicking instead of just adding parameters
