simple fading image swap
提问by HerrimanCoder
I'm having trouble finding a simple jquery image swap. Most the examples I've found are more complex than I need, and do things I don't want.
我很难找到一个简单的 jquery 图像交换。我发现的大多数示例都比我需要的更复杂，并且会做我不想做的事情。
Objective: I have 5 images I want to fade in, slide in, or etc. I would love to fade/dissolve from one image to the next, but slide would be fine too. When the page 1st loads, I want the 1st image to show for 4 seconds...then fade to the next image, 4 seconds, then the next, etc. Infinite loop.
目标：我有 5 张图像要淡入、滑入等。我想从一个图像淡入/溶解到下一个图像，但幻灯片也可以。当第一个页面加载时，我希望第一个图像显示 4 秒......然后淡入下一个图像，4 秒，然后下一个，等等。无限循环。
Currently my code is a simple image swap, not very elegant:
目前我的代码是一个简单的图像交换，不是很优雅：
document.getElementById("imgMain").src = "images/yurt/sleigh.png";
What's the best and simplest way to accomplish this?
