is simple. Change the class of 11 lines of span to this: : class= "{net: read_id.indexOf (item.id) =-1}"
pass the value value to isInArray and return ture by traversing tzlist. If false is returned, it does not exist.
function isInArray (arr,value) {
for(var i = 0; i < arr.length; iPP){
if(value === arr[i]){
return true;
}
}
return false;
}
this.read_id.forEach((v)=>{
let aa = this.tzlist.find(c=>c.id==v);
if(aa){
// class xxx.
}
})</span>
