I am doing a palindrome coder challenge and I am very new to coding. I cannot get it to run right to save my life. I had someone look at it and they said it should be fine but obviously, something isn't right. I have tried various small changes, updating in VS each time and nothing seems to work.
$('#bntCrunch').on("click", function () {
var str = $('input').val()
function pal() {
const reversed = str
.split('')
.reverse()
.join('');
return str === reversed;
if (str == reversed) {
document.getElementById('output').innerHTML(str);
}
else {
document.getElementById('output').innerHTML("That is not a palindrome");
}
}
})
</script>
VS seems to say "pal has been defined but its value is never read" no matter where I call the function.
Watch out, if you want to be case insensitive, you'll have to add ".toLowerCase()" on each side of the "===" test.
$( document ).ready(function() { $( "#button" ).on( "click", function() { $('#result').text($('#test').val()===$('#test').val().split('').reverse().join('')?"OK":"KO"); }); });
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script> <input type="text" id="test" /> <input type="button" id="button" value="Test" /> <div id="result"></div>
you are already returning a boolean value in pal() function; this return str === reversed; you don't want to have that there.
also, remember to invoke the pal()
