I'm trying to create a simple keyword-based search function in a Twine story using Javascript. I've got something functional using this guide, but I'm trying to modify it slightly. I'd like the search to output all matches, rather than just the highest one, or at least the top 5 highest matches. Can anyone help me with this? I'm unfortunately not very familiar with Javascript so trying to figure out what to change and then what to change it to has been very difficult.
window.SearchTerm = window.SearchTerm || function (h, descr, kw) {
'use strict';
if (this instanceof SearchTerm) {
this.handle = h;
this.description = descr;
this.keywords = kw;
} else {
return new SearchTerm(h, descr, kw);
}
};
SearchTerm.add = function (h, descr, kw) {
termList.push(new SearchTerm(h, descr, kw));
};
SearchTerm.prototype = {
compare : function (stringArray) {
var term = this;
var matches = (function () {
var ret = 0;
stringArray.forEach( function (str) {
if (term.keywords.includes(str)) {
ret++;
}
});
return ret;
}());
return matches;
},
constructor : window.SearchTerm
};
$(document).on('change', 'input[name=search-box]', function (e) {
var string = $(this).val(),
matches = [], i, n = -1, highest = 0, content;
string = string.replace(/[^A-Za-z0-9\s]/, ' ');
string = string.replace(/[\s\s+]/, ' ');
string = string.trim();
string = string.split(' ');
termList.forEach( function (term) {
matches.push(term.compare(string));
});
for (i = 0; i < matches.length; i++) {
if (matches[i] > n) {
n = matches[i];
highest = i;
}
}
if (n <= 0) {
content = '';
} else {
content = termList[highest].handle + ': ' + termList[highest].description;
}
$('#output')
.empty()
.append(content);
});
// add your search terms here...
SearchTerm.add('Test', '#000', ['test', 'testing']);
SearchTerm.add('Test', '#001', ['test', 'testing']);
SearchTerm.add('Test', '#002', ['test', 'testing']);
// etc.
