if statement in jquery Isn't working

Question

alert(x) is false. But for some reason it is not going into the if statement? Any ideas?

Html

 @{bool x = false;
            foreach (var c in Model.Cleaner.TimeConfirmations.Where(l => l.date.ToShortDateString() == DateTime.Now.ToShortDateString() || l.date.ToShortDateString() == DateTime.Now.AddDays(1).ToShortDateString()))
            {
                     x = true;
            }
            <span class="ifAvailable" data-confirmationchecker="@x" value="15">@x</span>
           }

Jquery

var x = $(".ifAvailable").data('confirmationchecker')
alert(x);
if ( x == false) {
    alert("hi")
}

x values is something which is not false so that's why if is not being executed... — Geeky, Nov 28 '16 at 23:34
if you want to compare with false ..consider changing it to "false", — Geeky, Nov 28 '16 at 23:35

Data attributes can only contain strings:

The data-* attributes consist of two parts:

The attribute name should not contain any uppercase letters, and must be at least one character long after the prefix "data-"

The attribute value can be any string

So you're comparing the string "false" to the Boolean false, which are not the same.

Instead of

if (x == false)

use

if (x == "false")

Or, you could use this technique:

var x = ($(".ifAvailable").data('confirmationchecker') == "true");
alert(x);
if ( x == false) {
    alert("hi")
}

Thank you! It actually did not work with "false" only as "False" – Newbie Nov 28 '16 at 23:48

Your x is a string, convert the value into a boolean and then do the check

var x = $(".ifAvailable").data('confirmationchecker')
alert(x);
if (JSON.parse(x) == false) {
    alert("hi")
}

How can I convert a string to boolean in JavaScript?

Seems like the value of x is "false" string type, please try :

if ( x == "false") {
    alert("hi")
}

or cast your variable x to a bool type.
