Jquery改变点击的时间间隔，当点击函数完成时重置回默认值

Question

我有一个自定义内容滑动条，每隔5秒滑动一次。滑块也有下一个和上一个功能。

问题:

1. 当我点击下一步时，幻灯片不会立即发生

2. 点击next/prev后，滑块开始快速滑动

我想做的:

1。当我点击next/prev时，我希望滑块立即滑动，而不需要等待5秒的间隔。当幻灯片完成后，将时间间隔重置为默认值5秒。

Answer 1

我对你的function做了一些更新，如下所示:

参见内联注释

$(document).ready(function(){
    var foo = {
        content_width   : 200,
        box             : $("#content-slide-container"),
        interval        : 0,
        counter         : 1,
        pause           : 5000,
        bar             : false
    };
    function startSlider(){
        foo.interval = setInterval(function(){
            // Next
            if(foo.bar){
                slideLeft()//keep sliding left in a separate function
            // Prev
            }else{
                slideRight()////keep sliding right in a separate function
            }
        },foo.pause);
    }   
    //2 new functions for slideLeft and slideRight
    function slideLeft(){
        foo.box.animate({'marginLeft':'+='+(foo.content_width)});
        foo.counter--;
        if(foo.counter<= 1){
            foo.bar = false;
        }   
    }
    function slideRight(){
        foo.box.animate({'marginLeft':'-='+(foo.content_width)});
                foo.counter++;
                if(foo.counter>=16){
                    foo.bar = true;
        }
    }
    //end
    startSlider();
    function pauseSlider(){
        clearInterval(foo.interval);
    }   
    foo.box.on('mouseenter',pauseSlider).on('mouseleave',startSlider);
    $('#prev-slide').click(function(){
        if(foo.counter>1){
            foo.bar = true;
            pauseSlider(); //on click clear interval
            slideLeft() //call slideLeft
            startSlider() //start the slide again with interval
        }
    });
    $('#next-slide').click(function(){
        if(foo.counter<16){
            foo.bar = false;
            pauseSlider() //on click clear interval
            slideRight() //slide Right
            startSlider() //start it again
        }
    });
});

您应该将代码移动到setPrev和setNext函数。它们应该与startSlider函数处于同一级别。此外，您应该清除$('#prev-slide').click(function(){和$('#next-slide').click(function(){之后的间隔
