图像更改onclick在移动浏览器中不起作用 [英] Image change onclick not work in mobile browser

问题描述

我有一个代码，可以在单击图像时更改图像.但是，由于我使用的是mouseup/mousedown，是否有办法使其也可以在移动浏览器中使用?

I have a code that will change the image upon clicking on the image. However, since I am using mouseup/mousedown, is there a way to make it so that it also work in mobile browsers as well?

$(document).ready(function(){
  $(".menulink").eq(0).mouseup(function(){
        $('#menu1').attr('src', 'http://placehold.it/333/3ef/img/picture2.jpg');
  });
  $(".menulink").eq(0).mousedown(function(){
        $('#menu1').attr('src', 'http://placehold.it/333/fe3/img/picture1.jpg');
  });
  $(".menulink").eq(1).mouseup(function(){
        $('#menu2').attr('src', 'http://placehold.it/333/3ef/img/picture2.jpg');
  });
  $(".menulink").eq(1).mousedown(function(){
        $('#menu2').attr('src', 'http://placehold.it/333/fe3/img/picture1.jpg');
  });
});

推荐答案

是的，您需要使用touchstart和touchend.我还提高了效率，希望您不要介意.

Yes, you need to use touchstart and touchend. I also made this slightly more efficient, hope you don't mind.

$(function(){
    var $menulink = $('.menulink'),
        $menu1 = $('#menu1'),
        $menu2 = $('#menu2');

    function setSrc($menu,$src){
        $menu.src = $src;
    }

    $menulink.eq(0).on({
        'mouseup touchstart':function(){
             setSrc($menu1[0],'http://placehold.it/333/3ef/img/picture2.jpg');
        },
        'mousedown touchend':function(){
             setSrc($menu1[0],'http://placehold.it/333/3ef/img/picture1.jpg');
        }
    });

    $menulink.eq(1).on({
        'mouseup touchstart':function(){
             setSrc($menu2[0],'http://placehold.it/333/3ef/img/picture2.jpg');
        },
        'mousedown touchend':function(){
             setSrc($menu2[0],'http://placehold.it/333/3ef/img/picture1.jpg');
        }
    });
});

这可能更加有效，如果您不仅拥有这两个功能，那么它尤其有用.

This might be even more efficient, and is especially helpful if you have more than just the two.

$(function(){
    var $menulink = $('.menulink');

    for(i=$menulink.length;i--;){
        var $menu = $('#menu'+(i+1))[0];

        $menulink.eq(i).on({
            'mouseup touchstart':function(){
                 $menu.src = 'http://placehold.it/333/3ef/img/picture2.jpg';
            },
            'mousedown touchend':function(){
                 $menu.src = 'http://placehold.it/333/3ef/img/picture1.jpg';
            }
        });
    }
});

这只是要考虑的另一种选择.

Just another option to consider.
