问题描述
我有一个很长很长的 html，需要包含在 Javascript 字符串中，而 Javascript 字符串又包含在 Java 字符串中，如下所示:
I have a long very long html which needs to be enclosed in Javascript string which in turn is enclosed in Java string as follows:
String html = "javascript:var html='...all goes here...';void(0);";
现在写到哪里了...all到这里...，所有的html包括"和'甚至其他特殊字符.我可以用Java的方式跳过它们吗?
Now where is written ...all goes here... , there is all html including " and ' and even other special characters. Can I skip them in the Java way?
推荐答案
在这里，您可以体验多次解释字符串的乐趣.您的 " 引号需要为 Java 转义，但您的 ' 引号需要为 javascript 转义.因此，您的 " 引号可以正常转义，但是当解释 javascript 时，您的 ' 引号需要在它们前面加上 \ 字符，所以你的java字符串中需要一个文字\(或\，一个转义的).因此，如果您将 html 变量设置为 html:
Here you get to the fun of strings interpreted multiple times. your " quotes need to be escaped for java, but your ' quotes need to be escaped for javascript. Thus, your " quotes you can escape normally, but your ' quotes need the \ character to be in front of them when the javascript is interpreted, so you need a literal \ in your java string (or \, an escaped ). thus, if you set your html variable to the html:
<span class="class">Here's Johnny!</span>
您需要:
String html = "javascript:var html='<span class=\"class\">Here\\'s Johnny!</span>';void(0);";
