如何转换Angular 4中附加反斜杠的双引号字符串

Question

例如

"{"$type":"Equal","value":
 {"$type":"UserField","value":"country"},"compareValues":
 [{"$type":"Literal","value":"INDIA"}],"joinvalues":
 [{"$type":"Literal","value":null}]}"

到

 "{\"$type\":\"Equal\",\"value\":
  {\"$type\":\"UserField\",\"value\":\"country\"},\"compareValues\":
  [{\"$type\":\"Literal\",\"value\":\"INDIA\"}],\"joinvalues\":
  [{\"$type\":\"Literal\",\"value\":null}]}"

Answer 1

var json = {"$type":"Equal","value":
 {"$type":"UserField","value":"country"},"compareValues":
 [{"$type":"Literal","value":"INDIA"}],"joinvalues":
 [{"$type":"Literal","value":null}]}


JSON.stringify(json).replace(/\"/g, "\\\"");
