この16進ランダム化関数が新しい色を生成するために値(var hex)を渡すことに問題があります。私はまだイベントハンドラーでは良くないので、どんな助けも本当に感謝しています。事前に感謝:)ランダムヘックスカラージェネレーター+ RGBスライダーjquery

スターターはあなたのonclick="click()"が非必要である、あなたは$('#button').click(function(){/*do stuff*/})$('#button').click(function_name)のようなものをキャプチャするためにjQueryの.click()を使用することができるために、あなたは束を持っていますjslintまたはjshintのエラーが表示される場合は、表示されるエラーは次のとおりです。
