The object array in this format
const items = [
{
"name":"MEMORY 3600 DIMM KINGSTON",
"code":"445sdp"
},
{
"name":"SSD KINGSTON",
"code":"445sdA"
},
{
"name":"MEMORY HP 3600",
"code":"445sdD"
}
];
Your work is filter this array
if the text to search has a space, it must have the name of the two words
filterData(array,"MEMO hp")->[{"name":"MEMORY HP 3600","code":"445sdD"}]
filterData(items,"445sdp")-> [{
"name":"MEMORY 3600 DIMM KINGSTON"
"code":"445sdp"
}]
and if you do not have spaces you must search by name and by code
filterData(items,"memo /-KINGSTON")-> [{
"name":"MEMORY HP 3600"
"code":"445sdD"
}]
and if the name contains /- everything that goes next to it must be excluded for example
if text to search is '' or null retun all array
function filterData(items,search){
if (!search || search?.length == 0) {
return items;
}
let searchInput=search.replace(/\s\s+/g," ");
let textNegate=searchInput.split(' ').filter(rs=>rs.startsWith('/-')).map(rs=>rs.replace('/-',''));
searchInput=searchInput.replace(/[\s][/-]+.*/g, '');
searchInput=searchInput.replace(/[-/\\^$*+?.()|[\]{}]/g, '\\$&').toLowerCase();
let seachArray=searchInput.split(' ');
seachArray=seachArray.filter(rs=>!rs.startsWith('\-'));
return items.filter(rs=>{
let text=rs.name.toLowerCase();
// test if contain only on word negated
if(textNegate.length==1 && textNegate[0].length>0){
if(text.search(textNegate[0].toLowerCase())>=0)
{
"negate one word"
return false;
}
}
if(text.search(search)>=0)
return true;
if(seachArray.length==1 && rs.code.search(search)>=0){
return true;
}
let result=false;
for(let i=0;i<seachArray.length;i++){
if(!new RegExp(`${seachArray[i]}.*`).test(text)){
result=false;
break;

result=true;
