Question

I am retrieving data from a database, where the field contains a String with HTML data. I want to replace all of the double quotes such that it can be used for parseJS

Answer 1

String info = "Hello \"world\"!";
info = info.replace("\"", "\\\"");

String info1 = "Hello "world!";
info1 = info1.replace('"', '\"').replace("\"", "\\\"");

For the 2nd field info1, 1st replace double quotes with an escape character.
