只要动画有效，尝试停止jQuery click事件

Question

I have a content slider, additionally I made "prev" & "next" buttons. The buttons should only be clickable when the animation is complete (animations duration is 500ms). I tried to solve it with the :animated selector, but it won't work:

if (!$(".scrollContainer").is(':animated')) {
    $(".nextItems a").click(function() {
        $(".slideNavig").find('a.selected').removeClass('selected').parent().next().find("a").addClass('selected');
    });
}
if (!$(".scrollContainer").is(':animated')) {
    $(".prevItems a").click(function() {
        $(".slideNavig").find('a.selected').removeClass('selected').parent().prev().find("a").addClass('selected');
    });
}

Or quite simply, I need to stop the buttons click event for 500ms after a click. Can anyone help me please?

Answer 1

Move the if statement that checks if the thing is animated inside your click event handler:

$(".nextItems a").click(function() {
    if (!$(".scrollContainer").is(':animated')) {
        $(".slideNavig").find('a.selected').removeClass('selected').parent().next().find("a").addClass('selected');
    }
});

$(".prevItems a").click(function() {
    if (!$(".scrollContainer").is(':animated')) {
        $(".slideNavig").find('a.selected').removeClass('selected').parent().prev().find("a").addClass('selected');
    }
});

Also you could dry out your code by doing something like this:

$(".nextItems a").click(function() {
    nextPrevItem('next');
});

$(".prevItems a").click(function() {
    nextPrevItem('prev');
});
function nextPrevItem( direction ) {
    if (!$(".scrollContainer").is(':animated')) {
        $(".slideNavig").find('a.selected').removeClass('selected')
            .parent()[ direction ]()
            .find("a").addClass('selected');
    }   
}

You need the if statement inside the handlers:

$(".nextItems a").click(function() {
    if (!$(".scrollContainer").is(':animated')) {
        $(".slideNavig").find('a.selected').removeClass('selected').parent().next().find("a").addClass('selected');
    }
});

$(".prevItems a").click(function() {
    if (!$(".scrollContainer").is(':animated')) {
        $(".slideNavig").find('a.selected').removeClass('selected').parent().prev().find("a").addClass('selected');
    }
});

You can use .delay() (available in jQuery 1.4 and higher) or you can use .setTimeOut() .
