How To Run JavaScript On Server And Send DOM Results To Client

Nov 10, 2010

I've been stuck on this one for a while, so it's time to consult the pros. I've created a charting application that uses javascript to do heavy DOM manipulation/generation on the client (creating barcharts made of colored divs, etc).

Long story short, I want to avoid sending my js library to the client. Is there any way to create the content on the server, using my existing javascript library, and only send the javascript-generated HTML to the client?

Javascript - Want To Send Files From Client's Browser To Server?

Dec 24, 2010

I'm looking for possible ways for sending files from browser to server.
One obvious way is using form with enctype='multipart/form-data'.
I wonder if there are other ways than this.

The reason I ask you this question is this file uploader:

It's not flash based, but it sends the file in a way that it gives you a progress bar, but when you send a file with form with enctype='multipart/form-data' the whole file will be send to the server so you can't actually show a progress bar of uploading process.

C# - Send An Array Of Strings From One Page To Another?

Jun 1, 2010

I now have two pages. When I click on a link on page A, I open the other one (let's call it page B). When I do this, I want to send some information from Page A to Page B in the form of an array of strings. This array is different depending on what link I follow on Page A.

I know I could send this information via the URL with the ?string1=bla1&string2=bla2 etc., but I don't want it that way, as it can get complicated if there are too many strings in the array.

I think there is something similar, like a POST in PHP, but how would that be in ASP?

Define And Send A JSON Object Array?

May 17, 2010

I'm looking for a way to define and send a JSON object array. I've figured out how to define a single JSON object, turn it into a string and send it, but what about an array of this type? Probably something simple I'm overlooking...

var myColumnSetting = { "ColumnName": name,
"ColumnIndex": index
convert it to a string
var myJSONText = JSON.stringify(myColumnSetting, false);

Convert Datatable To Byte Array To Send As Email Attachment

May 13, 2014

Every morning we send out an email with a text file attached. This is a manual process so I am automating it.I am using an internal mail web service. Its last two parameters are a byte array which is the file contents and a string which is the file name. I passed (...gbytes, "test.txt") and the only thing wrong with it is text.txt is XML. I want it to be text (csv is fine because there is actually four columns that come from a datatable).So I am assuming what's making it XML is this code:

System.IO.MemoryStream stream = new System.IO.MemoryStream();
System.Runtime.Serialization.IFormatter formatter = new System.Runtime.Serialization.Formatters.Binary.BinaryFormatter();
formatter.Serialize(stream, ds.Tables[0]);
gbytes = stream.GetBuffer();

I am trying to search the Internet for how to convert a datatable to a byte array, but I can't find how to have it be text instead of XML. Also, another parameter our WS takes is a flag to say if it's XML, and I am setting this to false.

Javascript - Jquery.ajax Set With Async=true To Send Data Back To Server Not Working If Page Redirects/reloads.

Sep 3, 2010

I'm trying to save some content whenever a button/hyperlink is clicked using jquery.ajax (Using 3.5). The logic is as follows:

Through .bind in jquery I bind my own method(MakeLog) to a button click or hyperlink click. The click events of button/hyperlink contain nothing, I need to use .bind for selective controls.Now we have a button whose click event will fire a method, say MakeLog.Code snippet for MakeLog is as follows:

var xhr = jQuery.ajax({
url: "/Logger.aspx",
data: { content: logContent }, [code]....

This works fine in IE but in Firefox this is not sending the data back as expected.I tried to identify the issue and came across the following: .What I understand is that, whenver page is redirecting/reloading due to button click or hyperlink click the async call is not working properly.

Javascript - Not Pushing To Array?

Jul 22, 2010

Trying to push some coordinates, as well as some stuff specified in a form by the user, to an an array called "seatsArray". Here's my code:

<img onLoad="shiftzoom.add(this,{showcoords:true,relativecoords:true,zoom:100});" id="image" src="plan1.bmp" width="1024" height="768">
<script type="text/javascript">
var seatsArray = [];
<br><input id="backnave" type="radio" name="area" value="backnave" /> Back Nave<br>
<input id="frontnave" type="radio" name="area" value="frontnave" /> Front nave<br>
<input id="middlenave" type="radio" name="area" value="middlenave" /> Middle nave<br>
<input type="radio" id="standardseat" name="seat" /><label for="radio1">Standard</label><br>
<input type="radio" id="wheelchairseat" name="seat" checked="checked" /><label for="radio2">Wheelchair</label><br>
<form id="my_form" action="savetext.aspx" method="post" onsubmit="return prepare()">
<input type="text" id="file_name" name="file_name" rows="1" cols="20" />
<input type="hidden" name="seatsArray" />
<input type="submit" value="Save" />
<form id="my_form" action="savetext.aspx" method="post" onsubmit="return prepare()">
<input type="text" id="file_name" name="file_name" rows="1" cols="20" />
<input type="hidden" name="seatsArray" />
<input type="submit" value="Save" />
<script type="text/javascript">
function prepare();
document.getElementById('seatsArray').value = seatsArray.join();
return true;
<script type="text/javascript">
var coordinates = document.getElementById("image");
coordinates.onclick = function(e) {
e = e || window.event;
if (e && e.pageX && e.pageX) {
e.posX = e.pageX;
e.posY = e.pageY;
} else if (e && e.clientX && e.clientY) {
var scr = {x:0,y:0},
object = e.srcElement ||;
//legendary get scrolled
for (;object.parentNode;object = object.parentNode) {
scr['x'] += object.scrollLeft;
scr['y'] += object.scrollTop;
e.posX = e.clientX + scr.x;
e.posY = e.clientY + scr.y;
var desc = "";
if(document.getElementByID("backnave").checked) {
desc = "BN, "+desc;
} else if(document.getElementByID("middlenave").checked) {
desc = "MN, "+desc;
} else if(document.getElementByID("frontnave").checked) {
desc = "FN, "+desc;
if(document.getElementById('wheelchairseat').checked) {
//Wheelchair seat is checked
desc = "Wheelchair "+desc;
seatsArray.push(desc + e.posX, e.posY);

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))
using (StreamReader sr = File.OpenText(path))
string s = "";
while ((s = sr.ReadLine()) != null)

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.

Web Forms :: Add The Numbers To An Array In Javascript?

Jan 19, 2011

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?

Serializing A Javascript Array With Jquery?

var serializedCheckData = checksSinceLastPostBack.serializeArray();

Also if this works, how would I deserialize it in the code behind?

Convert Datatable To JavaScript Array

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.
