Hello folks.
I've come a cropper with a javascript if else statement. I know what I want to achieve with the javascript syntax which is almost identical to actionscript which I have better knowledge of. So...

Dom - declaring var - btnone

XML

<script type="text/javascript">
    $(document).ready(function(){
    var btnone = true;
    });
</script>

Function - The if / else statement fails to get called as you'll see alert("no")fires but alert("yes")doesn't.

XML

<script type="text/javascript">
$('#a').live('click', function() {
        alert("no");
        if(btnone == "true") {
        alert("yes");
        $('#one').animate({top: '+=50',}, 500, function() {
        $('#one').animate({top: '-=50'}, 1000 );
        });
        } else
        if(btnone == "false") {
        //**var btntwo = false;
        $('.9, .8').hide();
        }
});
</script>

P.S - I also would like to control other var true or false values like so...refer to **. Correct method?
Any ideas? Many Thanks.

You've set the variable to a boolean, but you're comparing it to a string

if(btnone == "true")

try this

if(btnone == true)

Solution 3

You declared btnone in an anonymous function, which means it is not available in the scope of your event handler. Try moving the declaration out of the jQuery ready function:

XML

<script type="text/javascript">
    // global variable
    var btnone = true;

    $(document).ready(function(){
        // jQuery ready function - do DOM stuff here
    });
</script>
