Special characters

[Andre Hegge]

Hello! We scrape texts from html documents and put them into Raven. Then, we use javascript to retrieve and display the texts in other html documents.

A problem we have is that Raven adds \r\n\t and \" to the text strings. This is hardly expected behaviour. Why is this and is there an easy fix?

You need to parse the text as JSON.

In JS, you can do that using JSON.Stringify()

Hi! We already do this. The code:

var str = "<div class='result'>"

+ "<div class='result-title'>" + JSON.stringify(json.Messages[i].Author) + "</div>"

+ "<div class='result-date'>Updated " + stringifyTimestamp(JSON.stringify(json.Messages[i].Created).substring(7, 20)) + "</div>"

            + "<div class='result-text'/>" + JSON.stringify(json.Messages[i].Text) + "</div>"

            + "<a href='http://example.com'><div class='result-link'>" + JSON.stringify(json.Messages[i].ExternalId) + "</div></a>"

            + "</div>";

        result.innerHTML += str;

Can you show a full sample so we can reproduce?

[Starfish]

One moment, i need to compile it.

[Starfish]

The usage is:

sample.html?query=hello

It uses an old version of our api.

This is your own output from your own API.

What is the association to RavenDB?

[Starfish]

Yes, sorry about that. 

The api just serializes a Raven response though:

var q = session.Advanced.LuceneQuery<Message>(IndxName)

//.Statistics(out stats)

.Search(x => x.Text, query);

//.AndAlso()..WhereLessThanOrEqual("Created", DateTime.UtcNow.ToLongTimeString())

if (category != "") q = q.AndAlso().WhereEquals("CategoryId", category);

if (forum != "") q = q.AndAlso().WhereEquals("ForumId", forum);

if (author != "") q = q.AndAlso().WhereEquals("Author", author);

q = q.Take(12);

var q1 = q.ToList().OrderBy(s => s.Created).Reverse();

var qres = q.ToArray(); // do actual query

var jsonSerializer = new System.Web.Script.Serialization.JavaScriptSerializer();

string json = jsonSerializer.Serialize(qres);

That has nothing to do with RavenDB then, you are getting the value back.

Then you serialize it yourself.
