使用HTML5的contentmenu事件實現(xiàn)自定義右鍵菜單的功能

contextmenu事件：用以表示何時應該顯示上下文菜單，以便開發(fā)人員取消默認的上下文菜單而提供自定義的菜單

效果如下所示

html5左側彈出菜單怎樣實現(xiàn)

這個可以通過絕對定位，配合left設置 或者translate去實現(xiàn)

left的方法：

比如讓class為menu的元素寬為300px，高100%的，設置left為-300px；在這期間可以加一個過渡transition:left 0.3s ...；

然后讓class為menu active的元素設置 left設置為0就可以了 ，在這期間可以加一個過渡transition:left 0.3s ...；

然后可以通過Jquery的toggleClass('active');來實現(xiàn)切換

translate

比如讓class為menu的元素寬為300px，高100%的，設置left為-300px；在這期間可以加一個過渡transition:left 0.3s ...；

然后讓class為menu active的元素設置 transform:translate3d(-300px,0,0) ，在這期間可以加一個過渡transition:left 0.3s ...；

然后可以通過Jquery的toggleClass('active');來實現(xiàn)切換

這個過程中 需要注意 body需要overflow：hidden; (不然會有滾動條，可設置overflow-x即可)

left 和 translate 最好用translate ，translate3d可以開啟GPU硬件加速，性能會更好，體驗會更流暢

我github有類似小組件樣式

html5 浮動側滑菜單欄怎樣實現(xiàn)

一共有4種側滑動畫特效。這款CSS3菜單的特點是鼠標劃過時即可以各種動畫方式展開和隱藏菜單項，該動畫方式由CSS3中的transition-delay屬性來完成
