coldfusion - 如何使用单引号和双引号设置变量？

Question

如何在 ColdFusion 中设置在字符串中使用单引号和两个双引号的字符串变量？

MyVar = "Include multiple addresses on "Recipient's E-Mail" separated by commas.";

我知道我可以把它分解成几个变量或转义一些字符，但我想知道是否有一种标准的“最佳”方式，一种简洁易读的方式。

我可以这样做，但这很麻烦:

// THIS WORKS
MyVar = "Include multiple addresses on ";
MyVar = MyVar & '"Recipient's E-Mail "';
MyVar = MyVar & "separated by commas.";

我应该注意到我在函数中使用了 CFSCRIPT。这使得使用 savecontent 变得笨重。 CF 不喜欢我在 savecontent 中的 var (LOCAL.Info[i].EmailProd07) 的名称，所以我不得不重命名它。

// THIS WORKS
savecontent variable="LOCAL.MyVar" {
writeOutput("Multiple recipients may be included in ""Recipient's E-Mail"" separated by commas.");
};
LOCAL.Info[i].EmailProd07 = LOCAL.MyVar;

// THIS WORKS
LOCAL.Info[i].EmailProd07 = 'Multiple recipients may be included in "Recipient''s E-Mail" separated by commas.';

CF DOC :

Escaping quotation marks and number signs

To include a single-quotation character in a string that is single-quoted, use two single-quotation marks (known as escaping the single-quotation mark). The following example uses escaped single-quotation marks:

<cfset myString='This is a single-quotation mark: '' This is a double-quotation mark: "'> 
<cfoutput>#mystring#</cfoutput><br>

To include a double-quotation mark in a double-quoted string, use two double-quotation marks (known as escaping the double-quotation mark). The following example uses escaped double-quotation marks:

<cfset myString="This is a single-quotation mark: ' This is a double-quotation mark: """> 
<cfoutput>#mystring#</cfoutput><br>

Because strings can be in either double-quotation marks or single-quotation marks, both of the preceding examples display the same text:

This is a single-quotation mark: ' This is a double-quotation mark: "

我会补充:

<cfsavecontent variable="MyVar">
  Include multiple addresses on "Recipient's E-Mail" separated by commas.
</cfsavecontent>

如果空格很重要，请使用 trim()之后，或者如果内容很短，只需将标签和内容放在一行中，中间没有空格。
