queryDatav-model
sourceData
is based on the input keyword Filter array
watch: {
queryData(val){
if(val){
return this.sourceData.filter((el,index,self)=>{
return el.name.indexOf(val) >-1;
})
}
}}
the data source should not be changed, but the rendering should change. There is still no change on the page.
queryData(){
...
return this.sourceData.filter...
...
} Please complete Code
this is obviously wrong, you listen for changes in queryData , and then change queryData ? And if it's not what you want to change, it's not reflected in the question at all.
use computed instead of watch.
computed:{
filterdData(){
if(this.queryData){
return this.sourceData.filter((el,index,self)=>{
return el.name.indexOf(this.queryData) >-1;
})
}
return [];
}
}use filterdData in the template to get Filter data. Use sourceData to display all data.
