// clean content first
embedResponse.setAttribute('src', 'data:text/html;charset=utf-8,');
const response = await fetch(,

// accept HTML response
headers: {
'Accept': 'application/json, text/plain, */*',
'Content-Type': 'application/json'
},
// sent data if needed
body: JSON.stringify({data: ''})
});
// encode HTML response
const html = await response.text();
embedResponse.setAttribute('src', 'data:text/html;charset=utf-8,' + encodeURIComponent(html));
} catch (e) {
// catch errors and show them
embedResponse.setAttribute('src', 'data:text/html;charset=utf-8,' + encodeURIComponent(e));
console.error(e);
}
})();
There is another option, you can display HTML in new window as blob data:
const content = URL.createObjectURL(new Blob([response.data + overlay || ''], {type: "text/html"}));
window.open(content, "response", `width=640, height=480`).focus();

function versus(callable $first, callable $second, $repeat = 100000) {
$f = microtime(true);
foreach (range(0, $repeat) as $r) call_user_func($first);
$firstTimer = microtime(true) - $f;
$s = microtime(true);
foreach (range(0, $repeat) as $r) call_user_func($second);
$secondTimer = microtime(true) - $s;
printf(
'%s function is %.2f%% faster (%f vs %f)',
$firstTimer < $secondTimer ? 'First' : 'Second',
abs((($firstTimer - $secondTimer) / $firstTimer) * 100),
$firstTimer, $secondTimer
);
}
Example
versus(
function () {
$str = '!loremipsum';
return substr($str, 0, 1) === '!';
},
function () {
$str = '!loremipsum';
return $str[0] === '!';
}
);
Will print:
Second function is 36.72% faster (0.142766 vs 0.090349)
