2. The code of this blog post can realize relevant functions according to the requirements of the topic. At the same time, custom settings can be realized;

3. This article introduces JavaScript code exercises. The software used in this blog post is the code written by HBuilder X3.7.9. In principle, other software such as DW, VSCode or DW lower or higher versions are compatible. If you have In principle, it is possible to run normally if the software is required and the written software is not HBX;

1. Input values ​​​​in an array and output the largest number

1.1 Operation process and ideas

This is to input the specified value and calculate the maximum value through the loop of the for statement. and output the code. The specific thought process is as follows:

1.2 Code snippet

The code is as follows (example):

<!DOCTYPE html>
<html>
	<head>
		<meta charset="utf-8">
		<title></title>
		<script type="text/javascript">
			var z=parseInt(prompt("请输入总数值:"));
			var arr=[];
			for(var i=0;i<z;i++)
			{arr[arr.length]=parseInt(prompt("请输入第"+(i+1)+"个数值"));}
			var max=arr[0];
		   for(var i=0;i<z;i++)
			{
                if(arr[i]>max){
				   max=arr[i];
				}
			}document.write("最大值为 "+max);
			
		</script>
	</head>
	<body>
	</body>
</html>

1.3 JavaScript statement code

The code is as follows (example):

<script type="text/javascript">
			var z=parseInt(prompt("请输入总数值:"));
			var arr=[];
			for(var i=0;i<z;i++)
			{arr[arr.length]=parseInt(prompt("请输入第"+(i+1)+"个数值"));}
			var max=arr[0];
		   for(var i=0;i<z;i++)
			{
                if(arr[i]>max){
				   max=arr[i];
				}
			}document.write("最大值为 "+max);
			
		</script>

1.4 Run screenshot

The running results are as follows (example):
