按下键时，jQuery单击锚点

Question

This is what I have right now - it should simulate an anchor click when a user presses the left or right arrow key, but it doesn't - any ideas?

    $('body').bind('keydown',function(e){
        if(e.keyCode == 39){
            $(".next > a").click();
        }
        else if(e.keyCode == 37){
            $(".back > a").click();
        }
    });

Answer 1

触发click事件不会跟随链接AFAIK，您需要获取URL并手动进行操作：

location.href = $(".next > a").attr('href');

Answer 2

$('body').bind('keydown',function(e){
    if(e.keyCode == 39){
        $(".next > a").get(0).click();
    }
    else if(e.keyCode == 37){
        $(".back > a").get(0).click();
    }
});

Answer 3

$('body').bind('keydown',function(e){
    if(e.keyCode == 39){
        $(".next > a").trigger('click');
    }
    else if(e.keyCode == 37){
        $(".back > a").trigger('click');
    }
});

use trigger
