Getting a json string request parameter

Question

I have a json object and when it is passing through a request parameter on client side,and server side the json string is breaking from space character.

ex:

{"id":100,"age":15,"name":"sample string"}

when its come to the request.getParameter() showing like this

{"id":100,"age":15,"name":"sample

JAVASCRIPT

var location='MyAction.do?method=myMethod';
var form = '<input type="hidden" name="transactionId" value="'+getSession()+'" /><input type="hidden" name="myInfo" value='+JSON.stringify(myInfo)+' />';
$('<form action="' + location + '" method="POST">' + form + '</form>').appendTo($(document.body)).submit();

JAVA

String myInfo = request.getParameter("myInfo");

This is only happening when info string having space characters.how can I get the full string?

thanks.

You should share some other details with us, such as server side framework and client side code as well — Vincenzo

Are you sure it's a space and not a new line? Can you control how the JSON string is being passed? If you're using the querystring parameters, you should URLencode your JSON string before adding to the URL — jasonscript

@jasonscript yes I'm passing it as querystring.what do you mean by encoding.doing spaces to '%20'? — user1727557

You can encode your values

value='+JSON.stringify(myInfo)+'

This will give the raw string with spaces etc. You can use the in-built encodeURIComponent(string) method to encode your string

var myInfo = {"id":100,"age":15,"name":"sample string"};
encodeURIComponent(JSON.stringify(myInfo));

this returns the encoded string. This doesn't contain any symbols that might confuse the browser ({}[space]&? etc)

%7B%22id%22%3A100%2C%22age%22%3A15%2C%22name%22%3A%22sample%20string%22%7D

You can then decode it using decodeURIComponent(string)

var request_value = decodeURIComponent('%7B%22id%22%3A100%2C%22age%22%3A15%2C%22name%22%3A%22sample%20string%22%7D');
JSON.parse(request_value);
