I have an input for live search on JSON objects

<input type="input" id="searchtxt" placeholder="Search">

And here is my JS code

$('#searchtxt').keyup(function(){
 var Field = $(this).val(); 
 var regex = new RegExp(Field,"i");
   $.each(data, function(key, val){
     if (val.name.search(regex) != -1) {
        //Do something
     }
   });
 });

Having the i as a flag I can only make my regex case sensitive but how can I also make it to match with accented characters because my JSON contains characters such as Ά,έ,Ί (Greek alphabet) etc.

For example:

var data = [
{"id":"1",
"name":"Παράδειγμα",
},
{"id":"2",
"name":"Ίδιο Κείμενο",
}];

So, if I search "Παραδέιγ" val.name.search(regex) will return -1 cause of ά/έ but I want to have a match.

In general, the JS Regexp engine is not very Unicode-friendly, therefore accent marks are parsed as different characters and there doesn't seem to be a flag to ignore those. The best solution is to use an external library, such as XRegexp, which is the one I have seen suggested most often.

Another option would be to remove diacritics using a function like this one and then use a regexp as usual.

  • I have already tried to use a similar function to remove the diacritics but then I have a match if I search for "Πάράδειγμά" but not with "Πάραδειγμά" because there is the "ά" character in the JSON. – orestiskim Oct 25 '18 at 11:23
