我有一个将字符串转换为数字的函数

<cffunction name="convertToNumber" returntype="numeric">
    <cfargument name="separator" required="Yes" type="string" />
    <cfargument name="number" required="Yes" type="string" />

    <cfset LOCAL.arrSeparator = ["comma", "period", "lakh_crore"] />

    <cfif ARGUMENTS.separator eq "comma" or ARGUMENTS.separator eq "lakh_crore">
        <cfif ListLen(ARGUMENTS.number, ".") eq 2>
            <cfset LOCAL.integral = ListFirst(ARGUMENTS.number, ".") />
            <cfset LOCAL.fractional = ListLast(ARGUMENTS.number, ".") />
        <cfelse>
            <cfset LOCAL.integral = ARGUMENTS.number />
            <cfset LOCAL.fractional = "" />
        </cfif>

        <cfset LOCAL.integral = Replace(LOCAL.integral, ",", "", "ALL") />
        <cfset LOCAL.returnValue = LOCAL.integral />

        <cfif Len(Trim(LOCAL.fractional))>
            <cfset LOCAL.returnValue &= "." & LOCAL.fractional />
        </cfif>
    </cfif>

    <cfif ARGUMENTS.separator eq "period">
        <cfif ListLen(ARGUMENTS.number, ",") eq 2>
            <cfset LOCAL.integral = ListFirst(ARGUMENTS.number, ",") />
            <cfset LOCAL.fractional = ListLast(ARGUMENTS.number, ",") />
        <cfelse>
            <cfset LOCAL.integral = ARGUMENTS.number />
            <cfset LOCAL.fractional = "" />
        </cfif>

        <cfset LOCAL.integral = Replace(LOCAL.integral, ".", "", "ALL") />
        <cfset LOCAL.returnValue = LOCAL.integral />

        <cfif Len(Trim(LOCAL.fractional))>
            <cfset LOCAL.returnValue &= "." & LOCAL.fractional />
        </cfif>
    </cfif>

    <cfreturn LOCAL.returnValue />

</cffunction>

<cfset separatorNumber = StructNew() />
<cfset separatorNumber.comma = "1,234,567,890.123456">
<cfset separatorNumber.period = "1.234.567.890,123456">
<cfset separatorNumber.lakh_crore = "1,23,45,67,890.123456">

<cfloop collection="#separatorNumber#" item="separator">
    <p>
        #separator# :
        <input type="Text" value="#convertToNumber(separator, separatorNumber[separator])#">
        Length : #Len(convertToNumber(separator, separatorNumber[separator]))#
    </p>
</cfloop>

长度为 17，但在输入文本中，它在第一个字符处添加了额外的空格。我真的不知道如何删除多余的空白，当我添加 ToString(Trim())

<input type="Text" value="#ToString(Trim(convertToNumber(separator, separatorNumber[separator])))#">

它仍然有额外的空白

谢谢你

您是否尝试添加output="false"到您的功能标签？

<cffunction name="convertToNumber" returntype="numeric" output="false">...</cffunction>

希望有帮助。

我遇到了类似的问题，对我有用的是将方法返回的值放入变量中，然后输出变量而不是方法的返回值。我根本没有格式化它，但不知何故这有所帮助。

这很简单。放入<cfsilent>你的<cffunction>. 需要放在<cfsilent>后面<cfargument>。

我在我的博客中写过关于 cffunction 中的额外空间的文章。

<cffunction name="convertToNumber" returntype="numeric">
    <cfargument name="separator" required="Yes" type="string" />
    <cfargument name="number" required="Yes" type="string" />
    <cfsilent>
        <cfset LOCAL.arrSeparator = ["comma", "period", "lakh_crore"] />
        <cfif ARGUMENTS.separator eq "comma" or ARGUMENTS.separator eq "lakh_crore">
            <cfif ListLen(ARGUMENTS.number, ".") eq 2>
                <cfset LOCAL.integral = ListFirst(ARGUMENTS.number, ".") />
                <cfset LOCAL.fractional = ListLast(ARGUMENTS.number, ".") />
            <cfelse>
                <cfset LOCAL.integral = ARGUMENTS.number />
                <cfset LOCAL.fractional = "" />
            </cfif>
            <cfset LOCAL.integral = Replace(LOCAL.integral, ",", "", "ALL") />
            <cfset LOCAL.returnValue = LOCAL.integral />
            <cfif Len(Trim(LOCAL.fractional))>
                <cfset LOCAL.returnValue &= "." & LOCAL.fractional />
            </cfif>
        </cfif>
        <cfif ARGUMENTS.separator eq "period">
            <cfif ListLen(ARGUMENTS.number, ",") eq 2>
                <cfset LOCAL.integral = ListFirst(ARGUMENTS.number, ",") />
                <cfset LOCAL.fractional = ListLast(ARGUMENTS.number, ",") />
            <cfelse>
                <cfset LOCAL.integral = ARGUMENTS.number />
                <cfset LOCAL.fractional = "" />
            </cfif>
            <cfset LOCAL.integral = Replace(LOCAL.integral, ".", "", "ALL") />
            <cfset LOCAL.returnValue = LOCAL.integral />
            <cfif Len(Trim(LOCAL.fractional))>
                <cfset LOCAL.returnValue &= "." & LOCAL.fractional />
            </cfif>
        </cfif>
        <cfreturn LOCAL.returnValue />
    </cfsilent>
</cffunction>

<cfset separatorNumber = StructNew() />
<cfset separatorNumber.comma = "1,234,567,890.123456" />
<cfset separatorNumber.period = "1.234.567.890,123456" />
<cfset separatorNumber.lakh_crore = "1,23,45,67,890.123456" />
