如何不结冰创造永恒的动画？ [英] How do create perpetual animation without freezing?

问题描述

我仍然在JavaScript中的新手。我试着写一个程序，使图像fadeToggle所有的时间，所以我用了，而条件语句（一定变数相结合）;运行和冻结我的电脑（然后记住，病毒基本上是无限的操作）后，我搜索放在这里了一下，意识到我也许应该，事实上，从来没有使用无限循环。

I am still a newbie at Javascript. I tried writing a program to make images fadeToggle all the time, so I used the while conditional statement (combined with a constant variable); after running that and freezing my computer (then remembering that viruses are basically infinite operations) I searched on here a bit, realized I should probably, indeed, never use infinite loops.

（实际上欲微光 - 这意味着从不透明0.9去0.6-0.9等...），所以其不一样fadeToggle，但仍保持了同样的问题;我怎么让它去无限？（不包括编写恶意code）

(Actually I want shimmer -- meaning to go from opacity 0.9 to 0.6 to 0.9 etc...) so its not the same as fadeToggle, but the same question remains; how do I make it go infinitely?(without writing malicious code.)

这是我写的，供大家参考：

This is what I wrote, for your reference:

<script>
$(document).ready(function(){
var always10 = 10;
while (always10 == 10) {
    $('.pimg').fadeToggle(2600);
                   }
});
</script>

另外，我在另一个线程，而（真）是无限循环更好的发现。所以另外一个问题：是无限循环的有时的确定

Also, I've found out on another thread that while(true) is better for infinite loops. So another question: are infinite loops sometimes OK?

推荐答案

由于Javascript asynchornous没有睡眠梅索德。但是相反，一个好主意是使用 的setInterval 或 的setTimeout

Since Javascript is asynchornous there is no sleep methode. But instead, a good idea is to use setInterval or setTimeout.

如果没有这些功能，你的循环是要采取大多数ressources，因为它可以，它可以导致冻结（取决于您的浏览器）。

Without these function, your loop is going to take as most ressources as it can and it can result in a freeze (depending on your browser).
