如何将新线替换为coldfusion上的空白区域

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?

我的任务是替换新行字符,但我不能.如果有任何办法,请告诉我？

我可以理解你的问题,但我们不能通过cfset生成换行符.并且#chr(13)&chr(10)#无效.它应该是chr(13)或chr(10).你可以逐个替换两个.并且ReReplace函数用于基于RegEx替换字符串.你可以在这里使用replaceNoCase.这是我的示例代码.

  <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>
