之前做项目需要使用js动态生成一串长度为32的流水号,以下方法可以实现:

<script>
 function randomString(len) {  
			len = len || 32;  
			var $chars = 'ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789';  
			var maxPos = $chars.length;  
			var pwd = '';  
			for(i = 0; i < len; i++) {
				//0~32的整数    
				    
				pwd += $chars.charAt(Math.floor(Math.random() * (maxPos + 1)));  
			}  
			return pwd;
		}
		console.log(randomString(32));
	</script>
