how to pass a C# ASP.NET array to a Javascript array? Sample code will also be nice.
Let's say for simplicity that in my aspx.cs file I declare:
int [] numbers = new int[5];
now I want to pass "numbers" to the client side and use the data in the array within javascript. How would I do this?
Iam getting an array of list from database to client side(javascript array). Now my aim to place those values in a div one by one and that div should attach to the textbox similar to Autocomplete extender.
View 4 RepliesI 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?

View 1 RepliesI need to know what would be the best choice of array to use given the following specifications. This array's size will be predermined upon the loading of the appication. 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 have a page with list box and user can select multiple values from that lst box. Now what I want to do is when user submits the page I want to generate a comma seprated string that contins the ID's of values selected and pass this string to stored procedure. String would look like something like that '2,5,9'
Now my question is how can I split these ids in my stored procedure and get the records based on these ID's. In want to pass this array to Source coloumn in the follwoing Stored procedure and get the data. Right now following stored procedure is working on the basis of single source id passed to it.

I have the following structure:
private struct S_indiv
{
public int[] x;
public int s;
public S_indiv(int[] p1, int p2)
{
x = p1;
s = p2;
}
}
and array:
private static S_indiv[] ind;
How can I pass this array through Postback?
I am trying to implement the autocomplete method for textboxes.
I would like to use the example based on jquerys autocomplete provided here
<head>
<link href="http://ajax.googleapis.com/ajax/libs/jqueryui/1.8/themes/base/jquery-ui.css" rel="stylesheet" type="text/css"/>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.4/jquery.min.js"></script>
<script src="http://ajax.googleapis.com/ajax/libs/jqueryui/1.8/jquery-ui.min.js"></script>
<script>
$(document).ready(function() {
$("input#autocomplete").autocomplete({
source: ["c++", "java", "php", "coldfusion", "javascript", "asp", "ruby"]
});
});
</script>
</head>
The first and Main problem is that i do not know the way of passing my values to the source:
By saying that i mean, supposing i have a a server-side ASP.NET function GetTheResults as listof(string) or GetTheResults as string ()
how am i supposed to pass those values as source required by the auto-complete?
The second problem is that the specific way does not use AJAX.
Which means i guess on the load of the form i will load all the available values to the source. Isn't that an overkill?
Is there a control that you can use? It can be done by fetching a binaryread from an aspx page but why there isn't a simple free image control that you can put in the page and feed it a byte array?

View 12 RepliesI have an array which contains around 50-200 hyperlinks. How can I pass this array to the client-side so that I can iterate through the array and display each hyperlinks as a list item?
The array will be stored in 'Application' as it's system wide and rarely changes. Could there be a more efficient way of achieving the hyperlinks as a list?
What I have is a table that holds 3 input elements, They represent order, name, value. The user can add a new row of 3 inputs to add as many of these sets of data as they want.
To accomplish the dynamically adding in of inputs I use jquery's clone method. That works fine and I am able to iterate through each and grab the values, however the real pain I am having is that when the user has entered in all of the data I want to pass that data to an asp.net page through jQuery's post method. How do I go about passing an array of strings so that I send this format to the asp.net page, and when I've done that how do i parse the data on the asp.net side of it.
Desired Data Format:
["Name|Link|Order", "Name|Link|Order", "Name|Link|Order"]
jquery Code so far:
$("#saveBtn").click(function (e) {
e.preventDefault();
$("#addPanel").slideUp(300);
//Perform Save Operation
var saveString = "";
$("#addTable tbody>tr").each(function () {
var o = $(this).find(".hsaorder").val();
var n = $(this).find(".hsaname").val();
var l = $(this).find(".hsalink").val();
saveString += n + "|" + l + "|" + o ;
});
////// Create Array here or some other method?
$.post("/modules/H/Modify.aspx", { OBVIOUSLY SOMETHING GOES HERE});
// Remove all but top table element to return to original state
$("#addTable tbody>tr").not("#addTable tbody>tr:first").remove();
});

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?

here is my code
protected void Page_Load(object sender, System.EventArgs e)

"Los Angeles",

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?
If I have an array with 1 row of 20 items, how can I get the width (20).
I know I can get the length with array.length.
I have tried getting it with array.width"
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......
Is there a short cut to simply adding the numbers 0 -20 to an array, and is there a shotcut to adding the 20 nuumbers minus a few such as 3, 9, and 17?
I have the following code:
<script type="text/javascript">
var checksSinceLastPostBack = new Array();
function clientSelectedIndexChanged(sender, eventArgs) {
var ajaxManager = $find("<%= RadAjaxManager.GetCurrent(Page).ClientID %>");
var serializedCheckData = checksSinceLastPostBack.serializeArray();
if (ajaxManager != null)
ajaxManager.ajaxRequest(serializedCheckData);
}
</script>
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?
I have a datatable that I need to convert into a javascript array. This will allow me to do client-side validations on my webpage.
My datatable has 6 columns. X rows depending of the query results.
I was looking to use Me.ClientScript.RegisterArrayDeclaration but I just can't find how to build my 2-dimentional array to feed to this declaration.
On google I found some exemple for a 1-dimensional array, but nothing for 2-dimentional and I am not good enough in Jscript to figure it out myself.
