I am trying to implement search filter and I have array:
Var aa = ["Sage","Salsify (usually Purple Salsify or Oyster Plant)"];
var regex = RegExp("[a-zA-Z]?");
var wordList = vegetables.filter((elem, index)=>{
return regex.test(elem);
})
I think this will match only characters but how to get full string "Salsify (usually Purple Salsify or Oyster Plant)" when user type Salsify?
For a simplistic filter, you could use String.prototype.includes():
var aa = ["Sage","Salsify (usually Purple Salsify or Oyster Plant)"];
var query = 'salsify';
var wordList = aa.filter((elem, index)=> elem.toLowerCase().includes(query.toLowerCase()));
console.log(wordList);To use a regular expression, your RegExp would need to be built dynamically based on the search query:
var aa = ["Sage","Salsify (usually Purple Salsify or Oyster Plant)"];
var query = 'salsify';
var expr = new RegExp(query, "gi");
var wordList = aa.filter((elem, index)=> expr.test(elem));
console.log(wordList);
i flag in the RegExp which means case-insensitiveIf you do:
aa.filter((e) => /.*Salsify.*/.test(e))
You'll get every element of aa in which the string Salsify appears.
