Question

I have this code in JS:

if($('.log input:checked')) 
    {
        alert('login checked');
        alert('do what you want');
    }
    else 
    {
    alert('login not checked');
        alert('you can not do what you want');
}

But it is not working correctly. IS the IF ELSE condition wrong?

Answer 1

if( $('.log input').is(':checked') ) { // true/false

You can use .is() in a jQuery fashion (it’s descriptive) and will return a boolean against the matched element.
But you can also use the JS .length property.

An even better solution (kindly suggested by @macek)

if( $('.log input').prop('checked') ) { // true/false
