使用JavaScript将每行的首字母大写

Question

I'd like to know how I could capitalize the first letter of a row in JavaScript like in this PHP code :

<?php

$textParts = explode("
", $text);
foreach ($textParts as $key => $value) {
   $textParts[$key] = ucfirst($value);
}

$text = implode("
", $textParts);

$text="namjaga da geureochi mwo narago dareugetni
ni mameul da gajyeodo naragabeorigo maneun
namjaga da geureochi mwo"

?>

<p>
<?php echo $text; ?>
</p>

In JS, I get the text into the "Roman" DIV after a tranformation :

<div id="Roman"> </div>

<script>

<?php include("../../tools/js/romantool.js"); ?>
function affichar() {
  document.getElementById('Roman').innerHTML = latin_to_roman(
    document.getElementById('Parol').innerHTML
  );
}
affichar();

</script>

Does anyone know how I should proceed to do as in the previous PHP example ? Thank you !

Answer 1

In fact I would go right in between the two suggested answers so far. I would use javascript to replace the line breaks with a tag that will add structure around text e.g.

var str = document.getElementById('Parol').innerHTML;
str = '<span>' + str.replace(/(?:
||
)/g, '</span><span>') + '<span>';
document.getElementById('Roman').innerHTML = str;

And than style it in whichever way you want using CSS, your case would be

   span {
        display: block;
    }

    span:first-letter {
        text-transform: uppercase;
    }

Adding structure to your text will help you manipulate it much easier
