如何在coldfusion中将新行替换为空空间

Question

<cfoutput>
<cfset str ="hai how are you? i am fine
what about you?" >
<cfdump var="#str#" /><br>
<cfset str = #replace(str,"#chr(13)&chr(10)#"," ","all")#>
<cfdump var="#str#" /><br>
<cfset str = #reReplace(str, "#chr(13)&chr(10)#"," ")#>
<cfdump var="#str#" />
</cfoutput>

上面的代码产生了这种输出。

hai how are you? i am fine what about you?
hai how are you? i am fine what about you?
hai how are you? i am fine what about you?

我的任务是替换新的行字符，但是我不能。如果有什么办法可以的话请告诉我？

我能理解你的问题，但我们不能用cfset生成换行符。#chr(13) & chr(10)#无效。应该是chr(13)或chr(10)。你可以一个接一个地做两件事。ReReplace函数用于替换基于RegEx的字符串。您可以在这里使用replaceNoCase。这是我的代码样本。

  <cfif isDefined("form.submit")>
    <cfset str =form.TestField>
    <cfoutput>
        #findNoCase(Chr(13), str)# <!--- It is available --->
        <cfset str = replaceNoCase(str, chr(13), ' ','All')>
        <cfset str = replaceNoCase(str, chr(10), ' ','All')>
        <cfdump var="#str#"><!--- string after replacement --->
    </cfoutput>
</cfif>
<form name="test" method="post">
    <textarea name="TestField"></textarea>
    <input type="submit"name="submit" value="submit">
</form>
