Hello Punk! In my daily boring...
I found something interesting that I will share with you, this is not too fancy or glam but still "fun-cy" for me, cz In my stupid knowledge this is really helpful and enough for me and myself.
HTML5 Input Datalist
At least, this is what W3Schools said in their example:
What if I wrap inside PHP Function?
When I work with HTMX I need isolated component that can be reusable a form. So I create a PHP Function that generate the Input Datalist.
// Filename: helpers/Utils.php
public static function selectSearch(string $inputId, array $options, int|string $selected = ''): string
{
$inputHTML = '<div class="relative">';
$inputHTML .= '<input type="text" id="' . $inputId . '" list="" placeholder="Search..." autocomplete="off" class="transition-[0.2s] w-full input input-sm input-bordered focus:shadow-md" />';
$inputHTML .= '<datalist id="' . $inputId . '_list" class="box-border overflow-y-auto absolute top-full mt-1 max-h-40 bg-white border shadow-md">';
$selectedText = '';
$selectedValue = '';
foreach ($options as $option) {
$text = \explode('#', $option)[1];
$value = \explode('#', $option)[0];
if ($selected == $value) {
$selectedText = $text;
$selectedValue = $value;
}
$inputHTML .= '<option class="block p-1 mb-px cursor-pointer hover:bg-gray-200" value="' . $option . '">' . $text . '</option>';
}
$inputHTML .= '</datalist>';
$inputHTML .= '<input type="hidden" name="' . $inputId . '" id="target_' . $inputId . '" value="'.$selectedValue.'" />';
$inputHTML .= '</div>';
$inputHTML .= '<script type="text/javascript">';
$inputHTML .= 'fancyDropdown("' . $inputId . '");';
$inputHTML .= 'setTimeout(() => document.getElementById("' . $inputId . '").value = "'.$selectedText.'", 350);';
$inputHTML .= '</script>';
return $inputHTML;
}
I create a static function inside Utils
class so I can use that function everywhere in my project.
Is that using TailwindCSS? Yes, it's too dirty. But fck it! It's work! (Don't blame on me, if you really programmer so read it)
You can see this script
:
$inputHTML .= '<script type="text/javascript">';
$inputHTML .= 'fancyDropdown("' . $inputId . '");';
$inputHTML .= 'setTimeout(() => document.getElementById("' . $inputId . '").value = "' . $selectedText . '", 350);';
$inputHTML .= '</script>';
Yes! Again I wrote JavaScript as a string in PHP, why not! And where is the fckin fancyDropdown
come from?!
Here is, I found a Question in StackOverflow that asked about

Here is this code:
function fancyDropdown(inputId) {
const input = document.getElementById(inputId);
const target = document.getElementById('target_' + inputId);
const datalist = input.nextElementSibling;
let minWidth = datalist.offsetWidth;
function outputsize() {
if (input.offsetWidth < minWidth) {
datalist.style.minWidth = input.offsetWidth + 'px';
} else {
datalist.style.width = input.offsetWidth + 'px';
}
}
new ResizeObserver(outputsize).observe(input);
input.addEventListener("input", function(e) {
datalist.style.display = "block";
const text = input.value.toUpperCase();
let hide = 1;
for (let option of datalist.options) {
if (option.value.toUpperCase().indexOf(text) > -1) {
option.style.display = "block";
hide = 0;
} else {
option.style.display = "none";
}
}
if (hide) {
datalist.style.display = "none";
}
});
input.addEventListener("click", function(e) {
let hide = 1;
for (let option of datalist.options) {
if (window.getComputedStyle(option, null).display == "block") hide = 0;
}
if (datalist.style.display == "block" || hide == 1) {
datalist.style.display = "none";
} else {
datalist.style.display = "block";
}
});
document.addEventListener("click", function(e) {
if (e.target.tagName == "OPTION") {
let inputValue = e.target.value.split('#');
input.value = inputValue[1];
target.value = inputValue[0];
}
if (e.target.tagName !== "DATALIST" && e.target.tagName !== "INPUT") {
datalist.style.display = "none";
}
});
datalist.style.display = "none";
}
