query transfer vue participates params

Vue router How to transmit reference

params、query What is it? ?

  • params:/router1/:id, there id be called params. for example /router1/123, /router1/789
  • query:/router1?id=123, there id be called query. for example /router1?id=456

query Mode transfer parameter and receive parameter
The ginseng : this. r o u t e r . p u s h ( p a t h : ′ / x x x ′ q u e r y : i d : i d ) t h i s . router.push({ path:'/xxx' query:{ id:id } }) this. router.push(path:/xxxquery:id:id)this.router.push Reference time , It doesn't cause the page to refresh . Data needs to be re requested , The code is as follows .

export default{


return {


// Initially load store data 

// shopNo When reloading 



// call API obtain shop data 
var shop = {
/* Acquired data */};

Receiving parameters : this.$route.query.id

params Mode transfer parameter and receive parameter

params The ginseng Routing interface : router.js: Routing settings here , When you use params When we pass the reference , Add the parameter name after the route , And when you pass on the ginseng , The parameter name should correspond to the parameter name set after the route . Use query Method , There is no such restriction , It can be used directly in jump
 Insert picture description here
The ginseng : this. r o u t e r . p u s h ( n a m e : ′ x x x ′ p a r a m s : i d : i d ) Pick up closed ginseng Count : t h i s . router.push({ name:'xxx' params:{ id:id } }) Receiving parameters : this. router.push(name:xxxparams:id:id) Pick up closed ginseng Count :this.route.params.id

Be careful : If no parameters are written on the route , It can also be passed on , But not in url It shows your parameters , And when you jump to another page or refresh the page, the parameters will be lost ( As shown in the figure below ), That depends on this parameter http Requests or other operations will fail .

query Biography and reference params The difference between biography and reference

  • In usage : query Use path To introduce ,params Use name To introduce , The receiving parameters are all similar , Namely this. r o u t e . q u e r y . n a m e and t h i s . route.query.name and this. route.query.name and this.route.params.name. Pay attention to receiving parameters , It's already r o u t e and No yes route instead of route and No yes router Oh. !!
  • On display : query More like us ajax in get The ginseng ,params It's similar to post, Let's be simple , The former displays parameters in the browser address bar , The latter is not shown, so both cannot be used at the same time !!!
