我正在尝试制作草图悬停应用。当光标悬停在网格方块上时,方块将填充当前拾取的颜色,当您再次将鼠标悬停在其上时,颜色将被删除。
最初一切似乎都在起作用。我可以将鼠标悬停在正方形上以应用red color
并重新悬停以将其删除,或按clear button
清除所有内容。但是,当我将颜色改为例如green
,我无法通过悬停移除颜色,clear button
无效。为什么会这样?

@jorges回答修复了问题的一部分。你还需要添加:
$(this).css({'background-color': 'inherit'})
$(this).removeClass('color')
后的悬停功能中。
然后用以下代码替换第44行:
$('.color').css({'background-color': c})

你忘了清除风格背景试试这个
function clear() {
$('button').on('click', function(){
$('.vlak').removeClass('color')
$('.vlak').css({'background-color':'inherit'})
})
}
