Question

I have this problem:
I have an HTML textarea which is filled by the user. (And he can press The enter button to go on a new line).
Then I take The value of The textarea using the command:

document.getElementById("textareaCommento")

And I pass The value to the servlet using an XmlHttpRequest.
In The servlet I save this value in a database.
Since this point I have no problems…

Then, in another part I want to get The values from The database. Using a servlet I make this query

Select * from comments

And I transform the results in json. Here I have The problem… The newline character makes my JSON string invalid. For example:

"Comment":"hello
Word"

How can I do?
Thanks in advance!

Answer 1

You have to replace the \n character from database to something like <br/>

For the replace see replace \n and \r\n with <br /> in java
