如何在Javascript中编写1到1000的奇数和偶数的脚本? [英] How to do a script for odd and even numbers from 1 to 1000 in Javascript?
问题描述
我正在学习一本带有已解决示例的Javascript，但是有一个没有解决方案的示例.我想知道怎么做...
I am studying a book of Javascript with solved examples but there is one example without solution. I would like to know how to do it ...
在JavaScript(在浏览器中)中，我应该做的是写1-1000的偶数，完成后写1-1000的奇数...我不确定如何在数字之间添加很小的暂停"书写以及如何知道第一个循环是否结束并开始写奇数?
In javascript (in browser) I should do is write even numbers from 1-1000 and after it is finished write odd numbers from 1-1000 ... I am not sure how to add there very small "pause" between number writing and how to know if first cycle is over and start writing odd numbers?
这是我的开始方式:
<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml11.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en">
<head>
<title>Test</title>
</head>
<body>
<script type="text/javascript">
/* <![CDATA[ */
var i;
for (i = 0; i < 1000; i++)
if ((i % 2) == 0)
document.writeln(i);
/* ]]> */
</script>
</body>
</html>
推荐答案
尝试一下:
function partA() {
for (var i = 0; i < 1000; i++){
if ((i % 2) == 0) document.write(i + ' ');
}
window.setTimeout(partB,1000)
}
function partB() {
for (var i = 0; i < 1000; i++){
if ((i % 2) !== 0) document.write(i + ' ');
}
}
partA();
旁注:
仅将 document.write 用于测试.如果执行它，则在加载的HTML文档上，所有HTML元素都将被覆盖.(如您在我的示例中所见)
Use document.write for testing only.
If you execute it, on a loaded HTML document, all HTML elements will be overwritten. ( As you can see in my example )
