我的尝试：
当我们再添加一个'\'时，它就可以了。但是如果我们删除一个，那就不行了
What I have tried:
when we add one more '\' ,then it is work fine.but if we remove one,then it is not work
推荐答案
在Javascript中，当你写下文字字符串：
In Javascript, when you write the literal string:
var s = 'click the \"Setup\" button';
您创建一个包含的字符串：
you create a string that contains:
click the "Setup" button
当你通过时字符串到 JSON.parse ，它将第一个视为字符串的结尾。然后它会看到，或} ，因为它已达到属性值的末尾，而是它找到标识符设置。
你必须逃避 \ 字符，以便它包含在传递给 JSON.parse 的字符串中：
When you pass that string to JSON.parse, it sees the first " as the end of the string. It's then expecting to see a , or a }, as it's reached the end of the property value, but instead it finds the identifier Setup.
You have to escape the \ character so that it's included in the string passed to JSON.parse:
var s = 'click the \\"Setup\\" button';
