正则表达式在双引号内转义双引号 [英] Regular expression to escape double quotes within double quotes

问题描述

我有一个字符串需要解析为JSON.

I have a string that needs to be parsed as JSON.

问题是，有时它可能包含双引号，从而导致解析错误.

The problem is, it may sometimes contain double quotes, causing errors in parsing.

例如:

{
    "id_clients":"58844",

    "id_clients_name" : ""100" test"qw"
}

我需要一个正则表达式来用\"替换"开头和结尾之间的所有双引号.

I need a regex to replace any double quotes between the opening and closing " with a \".

谢谢.

推荐答案

我尝试了它只是为了好玩，尽管修复生成器肯定更好.这可能会适合您的情况，或者至少会激发您的灵感:

I tried it just for fun, even though it is certainly better to fix the generator. This might work in your case, or at least inspire you:

您可以在此处

$( function() 
{
  var myString = "{ \"na\"\"me\": \"va\"lue\", \"tes\"\"t\":\"ok\" }";
  var myRegexp = /\s*\"([\w\"]+)\"\s*[,}:]/g;
  var match;
  var matches = [];

  // Save all the matches
  while((match = myRegexp.exec(myString)) !== null)
  {
      matches.push(match[1]);
      console.log(match[1]);
  }

  // Process them
  var newString = myString;
  for (var i=0; i<matches.length; i++)
  {
      var newVal = matches[i].replace(/\"/g, '\\\"'); 
      newString = newString.replace(matches[i], newVal);
  }
  alert(myString + "\n" + newString);
}
);
