The jquery and operator fails to function

I am encountering an issue with the code snippet below. The functionality involves a button that toggles a div. Within this toggle div, there are several other divs and elements.

$(function () {
    $('#btn').click(function (e) {
        e.preventDefault();
        console.log('clicked toggle');
        $('#Popover').toggle();
        if ($('#Popover:visible').length == 0) {
            $('#Popover').hide();
        } else {
            $('#Popover').show();
        }
    });
});

$(document).on('click', function (e) {
    var container = $('#Popover');
    var trigger = $('#btn');

    if (($(e.target).closest(trigger).length === 0) && ($(e.target).closest(container).length === 0)) {
        container.hide();
    }
});

The current behavior is satisfactory as the button successfully toggles the div. However, when I click on a div within the toggle div, the entire toggle div also hides.

This issue may be related to the functioning of the && operator in my code.

There is a possibility that it could be due to a postback issue. For reference, here is the onclick method for a specific div (div id="hourInc") located inside the toggle div:

 $('#hourInc').click(function (e) {
        e.preventDefault();
        var hour = $('#cn_TimeHour').val();
        if (hour < 12) {
            hour = (hour * 1) + 1;
        }
        else {
            hour = 0;
        }
        $('#cn_TimeHour').val(("0" + hour).slice(-2));
        setTime();
    });

Answer №1

When it comes to comparing values in JavaScript, the "==" and "===" operators act slightly differently.

The "===" operator, also known as the identity operator, works the same as the "==" operator except that it does not perform any type conversion. This means that for them to be equal, the types of the values being compared must match exactly.

For more information, you can refer to the Javascript Tutorial on Comparison Operators.

Using the == operator will first convert the values to a common type before comparison. On the other hand, the === operator will not do this conversion, leading to faster comparisons. If the values being compared are different types, === will simply return false. In situations where performance is crucial, using === may yield different results compared to ==, but in most cases, their performance will be similar.

Appreciate your input

The problem with the click event. I added return false to the end of those functions.
