Question

I have this JS function :

var i = 0;
for (i = 0; i < myArray.length; i++) {
    alert(myArray[i]);
}

but myArray[] is create on server side with c# :

ArrayList myArray = new ArrayList();

protected void Page_Load(object sender, EventArgs e)
{
    foreach (MyObject myobject in MyObjects)
    {
        myArray.Add(myobject.Description);
    }
}

so, how can I “pass” the C# array to Javascript? Or I need to print the whole javascript code on server side and send it to the server?

Answer 1

at before…

1)I will put a hidden in the page…

2) general a string like

"['a','b','c']" 

into the hidden at .cs

3) cast to the array from the string at javascript

var arr = eval(hiddenvalue);

4) use it as a array…
