LE 在 for 循环的测试表达式部分是什么意思 [英] What does LE mean in the test-expression part of a for loop

问题描述

您好，我对coldfusion 非常陌生，我正在尝试调试一些cfscript 逻辑.基本上我想知道le"在for循环的测试表达式部分是什么意思.我浏览了coldfusion docs，但找不到它的含义.我猜这意味着小于或等于，但我相信这表示为 LTE.以下是代码示例:

Hi I'm very novice to coldfusion and I am trying to debug some cfscript logic. Basically I want to know what "le" means in the test-expression part of the for loop. I have looked through the coldfusion docs but can't find what it means. I am guessing it means less than or equals, but I believe that is denoted as LTE. Here's a sample of the code:

for (i = 1; i le length; i = i + 1)

提前致谢.

推荐答案

这是一个 LTE 的另一种说法.这些是等价的:

It is an alternate way of saying LTE. These are equivalent:

 LESS THAN OR EQUAL TO
 LTE
 LE

但对于新代码，我会改用 <=.更直观.

But for new code, I would use <= instead. It is more intuitive.

for (i = 1; i <= length; i++) {
   ... 
}
