JsonArray in silverlight for javascript
I am creating a JsonArray like:
JsonArray jsonValues = new JsonArray();
for( int i = 0; i < values.Count; i++ )
{
var someSingleValue = values[i];
jsonValues.Add( string.Format( "Name: {0}", someSingleValue ) );
}
After that I send json values to my javascript in the .aspx page by call: HtmlPage.Window.Invoke ("call", jsonValues);
The call works and it gets there, however I have no idea how to iterate over those values and then retrieve them. I've tried: (in javascript)
for (var x in somevalues){ alert(somevalues); }
I've also tried:
for(var i = 0; i < somevalues.length; i++) {
alert(somevalues[i]);
}
but it fails (in both cases) any ideas?

Are you using the eval method to serialize a string for a JSON object?
function call(somevalues){
//somevalues is currently just a string.
var results = eval("(" + somevalues +")");
//results now should contain your array as a JSON object.
//and you should be able to iterate over it at this point.
for(var i = 0; i < results.length; i++){
alert(results[i]);
}
}

Assuming some of the values are indeed an array, you do it like this:
for(var i = 0; i < somevalues.length; i++) {
// do something with somevalues[i]
}
What you did is tell JavaScript to iterate over the properties of an object somevalues
, which is similar, but not the same as iterating using a regular loop for
.
EDIT: I'm willing to put your variable, somevalues
is it a string. Just do it alert(somevalues)
and find out what happens.
