在java中转义javascript字符串 [英] Escaping javascript string in java

问题描述

 < script type =text / javascript> document.write（< img src = \UpArrow.png \/> \）; < /脚本> 
  

有人可以帮忙吗？我继续尝试，最终这样...

 返回< script type = \text / javascript\\ \\> document.write（\< img src = \UpArrow.png \/> \）;< / script>; 
  

哪些不起作用，因为我需要在UpArrow.png之前和之后双重转义引号。因为它需要在JavaScript中转义，而不是在java中。

解决方案

Apache commons在 StringEscapeUtils ： escapeJavaScript 方法。

I need to make this into a string in java:

 <script type="text/javascript">document.write("<img src=\"UpArrow.png\" /> \"); </script>

Can someone help? I keep trying and it ends up like this...

return "<script type=\"text/javascript\">document.write(\"<img src=\"UpArrow.png\" /> \"); </script>";

Which doesn't work because I need to double escape the quotes before and after UpArrow.png. since it needs to be escaped in javascript and not in java.

解决方案

Apache commons have a methods just for this in StringEscapeUtils : the escapeJavaScript method.
