javascript - 字符串替换不起作用？

Question

我一直在尝试使用以下...替换为以下字符串

var r = response.replace('var s = getService().getValue(\"join\")', 'null');

但是，字符串保持不变，我不明白为什么。字符串本身采用以下格式..

{"r":[],"c":true,"c":{"tags":
[],"":3023,"s":".src.util.S@6f4e9e57","class":"class 
src.util.dtos.DTO","Type":"public","c":"m","s":0,"de
fault":false,"id":544,"d":"","n":4,"na":"S","tagString":"","Pages":5},"results":[],"q":"","msg":"var 
s = getService().getValue(\"join\")

实际的字符串本身有点长，但我希望您能从该摘要中理解。

Answer 1

如果你的

var s = getService().getValue(\"join\")

部分是JSON字符串中的JavaScript代码，替换前需要再次引用。

var r = response.replace('var s = getService().getValue(\\"join\\")', 'null');
