len（x）更好或x NEQ“更好的CFML？ [英] len(x) better or x NEQ "" better in CFML?

问题描述

此

<cfif len(x)>

或

<cfif x NEQ "">

哪一个更有效率和可读性？函数调用与比较空字符串？

Which one is more efficient and readable? Function call vs comparing empty string?

推荐答案

我使用：

 if(len("String"));

我认为代码更干净，因为他们喜欢说表达。有了这个语法你正在说的代码是如果这个字符串有一个长度做这里，与对方的代码是说如果字符串的长度是一个空白字符串做这个。

I think the code is much cleaner and as they like to say "expressive". With this syntax what you are saying with the code is "if this string has a length" do this where with the opposite your code is "saying if the length of the string is a blank string do this".

我还使用ColdFusions宽松的布尔值来处理很多事情：

I also use ColdFusions loose boolean values for lots of things like in addition:

  if(a + b){
   ...
   }
