我想在javascript变量中存储一些HTML / XML标记。问题是文本比较大。例如,如何将以下XML片段存储在javascript变量中?
<QuestionForm xmlns="[the QuestionForm schema URL]">

我假设您的问题是如何获取该确切的字符串,而不是您从Web服务或Ajax调用中检索的字符串。虽然出于很多原因这是一个非常糟糕的主意,但回答这个问题......
在JavaScript中没有真正好的方法。有些浏览器通过在行尾添加\
来支持行继续,因此您可以执行以下操作: / p>
var xml = '<QuestionForm xmlns="[the QuestionForm schema URL]">\
<Overview>\
<Title>Game 01523, "X" to play</Title>\
...';
但这是非标准的,事实上直接与JS规范相矛盾:
'LineTerminator'字符不能 出现在字符串文字中,即使 之前是反斜杠。
唯一真正可靠的方法是使用手动字符串连接:
var xml = '<QuestionForm xmlns="[the QuestionForm schema URL]">' + "\n" +
' <Overview>' + "\n" +
' <Title>Game 01523, "X" to play</Title>' + "\n" +
' ...';
你可以这样做一点整洁:
var xml = ['<QuestionForm xmlns="[the QuestionForm schema URL]">',
' <Overview>',
' <Title>Game 01523, "X" to play</Title>'
' ...'].join("\n");
但它仍然很糟糕。
此外,使用所有这些方法,您必须转义任何单引号,即将'
替换为\'
。我乍一看你的XML片段中没有看到任何内容,这很好。

我想你可能想在javascript中存储html / xml代码并在textarea或其他一些输入元素中显示。如果这是你的意图,这将对你有所帮助。
而不是javascript变量,将代码存储在div中并使用css ex:display:none
隐藏。如果要显示代码,可以使用$('#div id').text()
。

我建议你使用JSON,matey。它不那么冗长。并且javascript有很好的方法来处理它。如果您需要稍后在类中使用XML,则可以编写一个简单的适配器。

var string = (<r><![CDATA[
The text string goes here. Since this is a XML CDATA section,
stuff like <> work fine too, even if definitely invalid XML.
]]></r>).toString();
