For 流程图

JavaScript中 for 循环的流程图如下-

for 循环的语法是JavaScript，如下所示-

for (initialization; test condition; iteration statement) {
   Statement(s) to be executed if test condition is true
}

请尝试以下示例，以了解 for 循环在JavaScript中的工作方式。

复制代码

<html>
   <body>      
      <script type = "text/javascript">
         <!--
            var count;
            document.write("Starting Loop" + "<br />");
         
            for(count = 0; count < 10; count++) {
               document.write("Current Count : " + count );
               document.write("<br />");
            }         
            document.write("Loop stopped!");
         //-->
      </script>      
      <p>Set the variable to different value and then try...</p>
   </body>
</html>

运行上面代码输出

Starting Loop
Current Count : 0
Current Count : 1
Current Count : 2
Current Count : 3
Current Count : 4
Current Count : 5
Current Count : 6
Current Count : 7
Current Count : 8
Current Count : 9
Loop stopped! 
Set the variable to different value and then try...
