前言

1.若有选择，您可以在目录里进行快速查找；

2.本博文代码可以根据题目要求实现相关使用功能。同时可以实现自定义的设置；

3.本文介绍的是JavaScript代码习题，本博文使用的软件是HBuilder X3.7.9编写的代码，原则上其他软件如DW、VSCode或DW较低或较高版本的软件都是兼容的，若您有需要且编写软件不是HBX等软件原则上都是可以能正常运行的；

图1 编写软件举例（部分）

4.这里要特别说明，因为我使用的是HBX，所以是网页格式，我也单独把<script>语句粘贴了出来，有需要可直接复制<script></script>语句；

5.本博文代码是我在上学时写的，有一些地方没能完美实现，请包涵也请多赐教，若您发现了问题也请麻烦您将问题反馈给我，我好更正错误、总结完善、持续改善！

6.博文通常需要在浏览器运行，通常会弹出表单，输入数值并得出结果。本文使用的是谷歌浏览器，推荐使用谷歌浏览器；

提示：以下是本篇文章正文内容，下面案例可供参考

一、实现输出一个“天”字

1.1 运行流程及思想

这是通过输入特定的行数，通过循环方式输出指定文字的代码。具体思想流程如下:

1.2 代码段

代码如下（示例）：

<!DOCTYPE html>
<html>
	<head>
		<meta charset="utf-8">
		<title></title>
		<script type="text/javascript">
			var arr = new Array(new Array("*","-","-","-","-","*"),new Array("*","*","-","-","*","*"),new Array("-","-","-","-","-","-"),new Array("*","*","-","-","*","*"),new Array("*","-","*","*","-","*"),new Array("-","*","*","*","*","-"));
			for( var i in arr)
			{
				for(var j in arr[i])
				{document.write("&nbsp;&nbsp;")
					document.write(arr[i][j])+"";
				}
				document.write("<br>");	
			}
		</script>
	</head>
	<body>
	</body>
</html>

1.3 JavaScript语句代码

代码如下（示例）：

<script type="text/javascript">
			var arr = new Array(new Array("*","-","-","-","-","*"),new Array("*","*","-","-","*","*"),new Array("-","-","-","-","-","-"),new Array("*","*","-","-","*","*"),new Array("*","-","*","*","-","*"),new Array("-","*","*","*","*","-"));
			for( var i in arr)
			{
				for(var j in arr[i])
				{document.write("&nbsp;&nbsp;")
					document.write(arr[i][j])+"";
				}
				document.write("<br>");	
			}
		</script>
