Need help in scripting to push unique values in array

[shaik_irfan]

Hi,

I have a script which is on inbound action that takes the subject and search for a keyword and get the knowledge article number and push into an array. Which is working fine

But if in case i have duplicate keywords then it is pushing the kb number multiple times. how to push only unique number

var arr = [];
var substring = email.subject;
substring = substring.split(" ");

for(var i=0; i<substring.length; i++){

if(substring[i] != " "){

var kn = new GlideRecord('kb_knowledge');
kn.addEncodedQuery('metaLIKE'+substring[i]);
kn.query();
if(kn.next()){
	gs.log('Found kb');
	checked = 'true';
	
	var url = '/sp?id=kb_article&sys_id=' + kn.sys_id;
	var com = '[code]<a href="' + url + '" target="_blank" >' + gs.getMessage(kn.number) + '</a>[/code]';
	com += "\n";
	arr.push(com);
}

	

	}
}

If i send the subject as "I have issue with my computer" then i get one article like KB0000002

If i send the subject as "My Computer is not working, i already troubleshooted my computer" then i get result in my array as KB0000002, KB0000002

Since i found the Computer keyword twice i get kb number twice but i want to display only once

Can anyone please help me how to do this

Try with ArrayUtil unique method to get the unique values in array.

Hi Irfan,

Can you try below.

var arr = [];
var substring = email.subject.toLowerCase(); //converts to lower case
substring = substring.split(" ");

var converttoarray=[];
for(var j=0;j<substring.length;j++) //gts substring.length
{
converttoarray.push(substring[j]);//passes as comma separated values. 
}
var getarr = new ArrayUtil();
var getuniqueis = getarr.unique(converttoarray);
//gets unique from text My Computer is not working, i already troubleshooted my computer which becomes
//is,not,working,,i,already,troubleshooted,my,computer which took my computer once

for(var i=0; i<getuniqueis.length; i++){
if(getuniqueis[i] != " "){            //changed after 
var kn = new GlideRecord('kb_knowledge');
kn.addEncodedQuery('metaLIKE'+getuniqueis[i]);
kn.query();
if(kn.next()){
	gs.log('Found kb');
	checked = 'true';
	
	var url = '/sp?id=kb_article&sys_id=' + kn.sys_id;
	var com = '[code]<a href="' + url + '" target="_blank" >' + gs.getMessage(kn.number) + '</a>[/code]';
	com += "\n";
	arr.push(com);
}

	

	}
}

Just a minor update to the below condition is required. I think instead of "substring[i]" we should use a unique array "getuniqueis[i]". 

if(substring[i] != " "){  -->  if(getuniqueis[i] != " "){
