学过C语言的人，对此应该熟悉，完全是一样的，一个简单的while循环例子： 简单的while循环 <html> <head> <title>简单的while循环例子</title> <script language="javascript"> <!--hide me
var password="tograce"; var answer; while (answer!=password) { answer=prompt("input the password(tograce)",""); }
//show me--> </script> </head> <body> </body> </html> 下面代码功能是一样的: while loop var a_line=""; var loop = 0; while (loop < width) { a_line = a_line + "x"; loop=loop+1; } for loop var a_line=""; for (var loop=0; loop < width; loop++) { a_line = a_line + "x"; }
