[英]Is it faster to swap an img src or show/hide multiple images?
What is the best practice to use when swapping an image on a webpage? 在网页上交换图像时使用的最佳做法是什么? Altering the image source or just showing/hiding multiple images on the page? 更改图像源或仅在页面上显示/隐藏多个图像?
you have to choose in order to balance speed, with your two options: 你必须选择以平衡速度,你有两个选择:
Altering the image source 改变图像源
this way, the page will load faster because it only gets the visible images but it will take a little longer to show the new image when you change src attribute 这样,页面加载速度会更快,因为它只获取可见图像,但更改src属性时显示新图像需要更长的时间
just showing/hiding multiple images 只显示/隐藏多个图像
this way, you are loading all the images on page load which will make it slower on loading and faster on swapping the images 这样,您在页面加载时加载所有图像,这将使加载速度变慢,并且交换图像时速度更快
在加载时,多个图像会减慢网页速度,但在执行时,我认为显示/隐藏图像最快
