I have a loop in js with a <select> and <option>, need to define a selected to the <option>, but as it is in the loop I can’t add straight into that <option>, has any suggestion or hint?
Follows the code:
var $html = "<select class='form-control' name='usuario' id='usuario'>";
for( var i in data ){
var u = data[i];
$html += '<option value="'+ u.login +'">' + u.login + '</option>';
}
$html += '</select>';
better describe which field or field condition you want, so that the field is selected

The option that the user selects, it should stick to the attribute Selected="Selected"... I’ve tried onclick on option but it doesn’t work.

it’s not the click that tests this, it’s better to test it with the onchange, you can use jquery? if you can, you have the ':lected' selector as per the link: http://api.jquery.com/selected-selector/

Yes, I can use Jquery...tested with change: $(Document). on('change', 'select#user>option', Function(){ $('select#user>option'). attr('Selected',true); });

tries like this: $(Document). on('change', 'select#user>option', Function(){ $(this). attr('Selected', 'Selected'); });

You can join
selectedinside the loop. How do you know which is theoptionWhat should be marked? Is there a pattern to this? Where do you know this information?– Sergio
If I put Selected inside the option, because it is inside a loop, all s will have this property, and when the user chooses, regardless of their choice, the value will always be the last one added!

First check which option or options should be checked, then handle such options within the loop, using a condition with
if... else– user28595
