I'm trying to get the first character of a fetched string with jQuery text(). It works if I test with a simple hard-coded string:
var str = 'hello';
var first_char = str.charAt(0);
console.log('first_char : ' + first_char);But I can't do it with the text of a label retrieved with text()
var str = $('.form-item-field-lorem-433 label').text();
console.log('str : ' + str);
var first_character = str.charAt(0);
console.log('first_character : ' + first_character);<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div class="form-item-field-lorem-433">
<input data-drupal-selector="edit-field-lorem-433" type="checkbox" id="edit-field-lorem-433" name="field_lorem[433]" value="433" class="form-checkbox form-check-input">
<label class="form-check-label" for="edit-field-lorem-433">
Asie-Pacifique
</label>
</div>I also tested with substring() and slice()
Can you explain to me what is not working?
The issue is because the string from text() also contains the whitespace from the HTML. You can use trim() to remove this:
var str = $('.form-item-field-lorem-433 label').text().trim(); // trim here
console.log('str : ' + str);
var first_character = str.charAt(0);
console.log('first_character : ' + first_character);<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div class="form-item-field-lorem-433">
<input data-drupal-selector="edit-field-lorem-433" type="checkbox" id="edit-field-lorem-433" name="field_lorem[433]" value="433" class="form-checkbox form-check-input">
<label class="form-check-label" for="edit-field-lorem-433">
Asie-Pacifique
</label>
</div>
