do ... while循环与while循环类似,除了条件检查发生在循环的末尾。这意味着即使条件为假,循环也将至少执行一次。
JavaScript中do-while循环的语法如下,
do{ Statement(s) to be executed; } while(expression);
请尝试以下示例,以了解如何在JavaScript中实现do-while循环,
<html> <body> <script> var count = 0; document.write("Starting Loop" + "<br />"); do{ document.write("Current Count : " + count + "<br/>"); count++; } while(count < 5); document.write ("循环停止!"); </script> </body> </html>
