I know that I can declare an array using the following method, but assume there is an easier way.
var elem as new Array();
elem[0] = 1;
elem[1] = 2;
elem[2] = 3;
and so on......

I'm working on an ASP.NET web app where I'm using a Wizard to take the client through a large series of steps.One of the steps includes calculating a bunch of numbers on the fly... the numbers calculate properly but when I click "next" and then go back again... some of the numbers are not retained.
function CalculateFields() {
txtSellingPrice = document.getElementById('<%=txtSellingPrice.ClientID %>');
//I get all of the elements like this...
//...
var regexp = /[$,]/g;xt" and then "previous"

But simply nothing is getting pushed to the array. I can tell this as I am using the following ASP.NET to write the array to a text file:
<script runat="server">
protected void Page_Load(object sender, EventArgs e)
{
string path = Server.MapPath(".")+"/"+Request.Form["file_name"] + ".txt";
if (!File.Exists(path))
{
using (StreamWriter sw = File.CreateText(path))
{
sw.WriteLine(Request.Form["seatsArray"]);
sw.WriteLine("");
}
}
using (StreamReader sr = File.OpenText(path))
{
string s = "";
while ((s = sr.ReadLine()) != null)
{
Response.Write(s);
}
}
}
</script>
The name of the text file is correct according to what the user put in the form "file_name". As you can see I made seatsArray a hidden form object so thats what the ASP.NET is trying to call.
Is something in the javascript in the wrong order or something? Because I just can't get it to fill up that text file.
How Can i fill an array that defined in javascript with c# in behind code?
EDIT:
here is my code
protected void Page_Load(object sender, System.EventArgs e)
{
string[] locations = new string[] {

View 2 RepliesI would to know how to pass variables. I have a variable in javascript but I dont know how to pass it to a textbox. I have read it is so easy using ajax, but I dont know how to use it. I believed this was just for not to have reload. Well, then how do I do it? I read I must use get and post, but I dont know how to use it.. for example I have the code:
function guardar() {
var completo = "hola mundo";
}
How do I get the variable completo to pass it in a textbox?

var serializedCheckData = checksSinceLastPostBack.serializeArray();
if (ajaxManager != null)
ajaxManager.ajaxRequest(serializedCheckData);

The
var serializedCheckData = checksSinceLastPostBack.serializeArray();
doesn't seem to work. Am I misunderstanding this?
Also if this works, how would I deserialize it in the code behind?

All I want to do is be able to add values to this array and replace preexisting array items with new values without the array changing size. Someone suggested that I use a Dictionary Array Object? I would appreciate any suggestions.

I want to pass to an array of controls' IDs to a javascript script function so it will switch control's enable state.
For example, in C# it would be like this:
func(false, new[] { "Control1", "Control2", "Control3" });
In that function I want to find corresponding controls and disable/enable them. For one control I do this next way:
<script type="text/javascript" language="javascript">
function switchControls(value, arr) {
for (var n = 0; n < array.length; n++)
document.getElementById([n]).disabled = value;
}
</script>
<asp:CheckBox runat="server"
onclick="switchControls(this.checked,
[
'<%= Control1.ClientID %>',
'<%= Control2.ClientID %>'
])"
Text="Take?" />
How to implement this properly? Have I to use jQuery?
