Using selectize.js, my current setup looks like this:
https://i.sstatic.net/EqhF8.png
Instead of only showing words that start with 'arm', it displays words or options containing 'arm' as a substring elsewhere.
I want to modify the function to display only words or options that begin with 'arm'.
Despite consulting the usage documentation at https://github.com/selectize/selectize.js/blob/master/docs/usage.md, I couldn't find a solution. Does anyone have any ideas?
To sort items and loop through the entire list based on relevance, you can utilize the score property. Each item is assigned a score of 1 if it's highly relevant, 0 if it doesn't match, and thus excluded from the list. With this understanding, we can create a customized function.
Upon entering a new character, the score function is invoked. It then evaluates each item using the following structure:
item = {
text: 'Armband',
value: 'Armband',
}
For evaluation, we take the lowercase version of item.text, compare it with the lowercase search value. If item.text begins with the search term, return 1 indicating inclusion; otherwise, return 0 for exclusion. The complete score function is outlined below.
score: function(search) {
var score = this.getScoreFunction(search);
return function(item) {
return item.text
.toLowerCase()
.startsWith(search.toLowerCase()) ? 1 : 0;
};
},
An example showcasing this functionality in action is provided below.
if (!String.prototype.startsWith) {
String.prototype.startsWith = function(search, pos) {
return this.substr(!pos || pos < 0 ? 0 : +pos, search.length) === search;
};
}
$('.select').selectize({
placeholder: 'Maak een keuze',
openOnFocus: true,
items: [''],
score: function(search) {
var score = this.getScoreFunction(search);
return function(item) {
return item.text
.toLowerCase()
.startsWith(search.toLowerCase()) ? 1 : 0;
};
},
