停止ColdFusion输出的空格的正确方法是什么？
What would be the correct way to stop the white space that ColdFusion outputs?
我知道有 cfcontent 和 cfsetting enableCFoutputOnly 。
推荐答案
除了< cfsilent> ，< cfsetting enablecfoutputonly =yes> 和&cf; cfupcessingdirective suppressWhiteSpace =true> 为< cfcontent reset =true/> 。您可以使用文档开头删除空格。
In addition to <cfsilent>, <cfsetting enablecfoutputonly="yes"> and <cfprocessingdirective suppressWhiteSpace = "true"> is <cfcontent reset="true" />. You can delete whitespaces at the beginning of your document with it.
HTML5文档将以如下方式开始：
HTML5 document would then start like this:
<cfcontent type="text/html; charset=utf-8" reset="true" /><!doctype html>
XML文档：
<cfcontent reset="yes" type="text/xml; charset=utf-8" /><CFOUTPUT>#VariableHoldingXmlDocAsString#</CFOUTPUT>
这样你就不会得到Content is not allowed in prolog - XML文档的错误。
This way you won't get the "Content is not allowed in prolog"-error for XML docs.
如果你从一个函数中得到不需要的空格，使用输出 -attribute来抑制任何输出， result as string - 例如：
If you are getting unwanted whitespaces from a function use the output-attribute to suppress any output and return your result as string - for example:
<cffunction name="getMyName" access="public" returntype="string" output="no">
<cfreturn "Seybsen" />
</cffunction>
