Optymalizacja wordpress

Poniżej kilka trików które pozwoliły mi przyspieszyć bloga z 32/22 w PageSpeed Insigth do 90/100 - oczywiście to zależy od strony, ilości zdjęć, szybkości serwera itp, wszystko ma znaczenie.
I to jest blog ze zdjęciami (blog.grzegorztomicki.pl), jak dla mnie bardzo zacnie 🙂

1. Będziemy potrzebować dostęp do .htaccess
W którym dodajemy (nie będę opisywał co dokładnie jest w nim robione bo wszystko można znaleźć opisane w internecie)

<ifmodule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]

jQuery UI Autocomplete highlight

Mamy sobie prosty formularz. Do podpowiedzi użyjemy pluginu jquery autocomplite. Chcemy również dodać wyboldowanie podpowiedzi.
Dokładnie uzyskać taki efekt "meble, Waszawa" gdzie highlight jest zmianą koloru na czarny i wyboldowaniem.

<form id="search" action="/" method="GET" role="search">
  <fieldset>
    <input id="query" type="text" name="query" value="" maxlength="255" autocomplete="off"
      placeholder="Produkt, usługa, miasto, ulica"/>
    <button type="submit" id="button-search"></button>
  </fieldset>
</form>

A teraz trochę js 😉

Wyrażenie regularne walidacja daty

function testdate(fld, form) {
  let blad = '';

  if (fld.value !== '') {
    const data = fld.value;

    const RegDate = /^(19|20)\d\d[-](0[1-9]|1[012])[-](0[1-9]|[12][0-9]|3[01])$/i;
    const wynik = RegDate.test(data);
    if (wynik === false) blad += ' – data\';
  }

  if (blad !== '') blad = `Proszę wypełnić pola: ${blad}`;

  if (blad !== '') {
    alert(blad);
    return false;
  }
}

Obliczania na formularzu

var fld_name;
var idx, nr;
cnt = f.elements.length;

for(i=0; i&lt;cnt; i++){
 if(f.elements[i].name.indexOf("kwota_budzetu_")!=-1) {
  fld_name = f.elements[i].name;
  idx = fld_name.lastIndexOf("_")+1;
  nr = fld_name.substr(idx);

f.elements["roznica_proj_"+nr].value =
   eval(f.elements["kwota_budzetu_"+nr].value) -
   eval(f.elements["wartosc_proj_"+nr].value);
 }
}
