Question

I try to do in a Servlet:

JSONObject json = new JSONObject();
json.put( "eventContent", "event" );
String script = "var object= " + json.toJSONString() + ";";
response.getWriter().print( something + script + another );

The content of script is of course:

var object = {"eventContent":"event"};

But I render this String into a javascript function and try to refer a existent javascript object “event”. So I need the value in the JSON Sting without quotes.

var object = {"eventContent":event};

any suggestions? 🙂

thanks a lot

I think it’s not really JSON, since you should not refer variables. Anyway you can obtain what you need by implementing the JSONString interface, like this.

public static void main(String[] args) throws JSONException {
    JSONObject json = new JSONObject();
    json.put( "eventContent", new JSONVariable("event") );
    System.out.println("var object= " + json.toString() + ";");
}

private static class JSONVariable implements JSONString { // implements JSONAware with com.googlecode.json-simple
    private final String name;

    public JSONVariable(String name) {
        this.name = name;
    }

    @Override
    public String toJSONString() {
        return name;
    }
}
