MVC4 C# Array conversion to Javascript-Array > Unwanted Encoding/Escaping

Question

2.00/5 (1 vote)

I need to convert data from my model that is available as an C# array to a Javascript array.

I tried JavaScriptserializer and other methods I found
but nothing worked so far. Maybe I got some kind of syntax error.

My site also uses Razor Viewengine. I don'T know if that may cause the problem.

Currently I use this

JavaScript

<script type="text/javascript">
                $(function() {
 var Orte = [@string.Join(",",Model.HaltestellenListe.Select(x=>"'"+x+"'"))];

the result of this line looks like this
var Orte = [&#39;Abbingwehr, Mast 1&#39;,&#39;Abelitz, B210/Abzw. Gr. Meer,&#39;]

Thats not what I need.

I need it to be a javascript array:

var Orte = ['Abbingwehr, Mast', 'Abelitz, B210/Abzw. Gr. Meer']

This is not really encoding. Both strings are equivalent, but in first case, HTML characters are escaped by character entities. Please see:
http://en.wikipedia.org/wiki/Character_entity[^],
http://www.w3.org/TR/REC-html40/sgml/entities.html[^].

Well at some point some code in my site or EF - not sure about where it happens, cause its not all my code - DOES call encoding. Even if the only characters converted are parenthesis.
And in the sites you postet it is also called like that. So I don't understand how this may help me.

I tried "unescape"

<script type="text/javascript">
$(function() {
var Orte = [unescape(@string.Join(",",Model.HaltestellenListe.Select(x=>"'"+x+"'")))];

but it does not solve the problem.

I get the escaped sequence with

var Orte = [unescape('Abbingwehr, Mast 1','Abelitz, B210/Abzw. Gr. Meer')]
And the processing of my array still does not work

The array is still not working properly.

I also tried

var Orte = [@HttpUtility.HtmlDecode(string.Join(",",Model.HaltestellenListe.Select(x=>"'"+x+"'")))];

But I get an compiler error then sayin Method has invalid arguments

I just would not call it "encoding", to avoid confusion. Just terminology. There are "encode" and "decode", but they are not related to what is called "encoding"...

I think you can sort your problem by yourself. Your question is answered, won't you agree?

If you still have a problem, please put the code and explanations to the body of the question, formatted, leave a comment here. Explain properly. "Still not working properly" is not informative. The problem is way too simple. Can use the debugger?

yes you are right.
Sorry-

"still not working" was refering to no valid array
anyway the problem is solved
thanks

you can close the thread if thats what you mean

Sergey Alexandrovich Kryukov 28-Feb-13 16:30pm

Not really. The thread is kept, and anyone can add another answers. Look at other threads. More than one accept is usual. You accept it or not, that's all what matters. A gave you exact recipe, that's all. You if disagree, you should better give your arguments...

Green button. You should know because you already accepted one. Thank you and good luck.

There are two solutions. One I gave and one you gave.
But yours was not a solution for my problem so do I klick that button anyway?

Sergey Alexandrovich Kryukov 28-Feb-13 16:53pm

Yes. Don't worry. Both will be accepted.

Solution 2

Found it. Seems like Razor was causing this

HTML

var Orte = [@Html.Raw(string.Join(",",Model.HaltestellenListe.Select(x=>"'"+x+"'")))];

did the trick :-)
