What is the best way to pass C# array to javascript variable ?

I have sample code but this return character by character from C# array, I want to return in normal way like word by word in javascript array;

C# code behind:

 public string[] names = { "John", "Pesho", "Maria"};
 public JavaScriptSerializer javaSerial = new JavaScriptSerializer();

javascript code:

 <script>
    var a = '<%= this.javaSerial.Serialize(this.names) %>';
    for (var i = 0; i < a.length; i++) {
        console.log(a[i]);
    }
 </script>

This script return all words from "names" array in single char array . I want to return in normal way like ["John"] ["Pesho"] ...

• Do you mean a single array of strings, like ["John", "Pesho", "Maria"] ? – p.s.w.g Commented Feb 18, 2013 at 17:55
• I want "a" variable to be equal to C# "names" array – TheChampp Commented Feb 18, 2013 at 17:56
• "This script return all words from "names" array in single char array"... can you show us what gets rendered? – spender Commented Feb 18, 2013 at 17:58

Replace

var a = '<%= this.javaSerial.Serialize(this.names) %>';

with

var a = <%= this.javaSerial.Serialize(this.names) %>;

You were putting the resulting JSON into a javascript string, which would result in your example output iterating through each character of the Serialize call.

your c# code will return a string, you have to first parse the string using JSON.parse, and then iterate through it:

var a = JSON.parse('<%= this.javaSerial.Serialize(this.names) %>');
for (var i = 0; i < a.length; i++) {
    console.log(a[i]);
}

or maybe as @Matthew said, don't put quotes around it, so you won't have to parse it.
