Javascript - Function PageLoad Not Working?
Aug 31, 2011
I have the following code which I want to run when the page first loads and then again when an update panel (asp.net) is run. Therefore I need to use function pageLoad() rather than document.ready.
function pageLoad() {
$(".zoomImage").each( function() {
$("<img src='"+$(this).attr("src").replace("-thumb.jpg",".jpg")+"' />").appendTo(".howitworksText > div");
});
};
Problem is I can only get this working with document.ready - so therefore not when the updatepanel is run.

The issue at hand is this. I want VB.Net code to be able to talk with Javascript code, specifically, passing variable values back and forth.A web page contains several DIV elements that actually can open and close kinda like a dropdownlist in it's functionality (there are 8 of these). Initially, when the page loads, these DIV's are closed. However, when a user opens a DIV or multiple DIV's, their are various textbox controls they can make changes to. When any changes are made, they click the submit button to save the changes. Then, when the page reloads, I want the program to remember which DIVs were open so after the page finishes loading, those DIVs that had changes made to them will be opened instead of closed. What would be the best way to handle this. Should it be done all in the code-behind file or javascript alone or both?

Not sure why this isn't working. There is no js error, but it just doesn't set the display property to "block". If I remove the inner most if statement, the display property for the div control is changed when the last radio button is selected from the group.

Im trying to get a connection between a JavaScript WebSocket and a TCP Server/Client applicat written in VisualBasic .Net . My problem is that the handshake fails. I do get a handshake request from the local website, but it does not accept my response.
The code of the JavaScript file:
<script type="text/javascript">
var ws;
function connect() {
[Code]....
I now get the correct Sec-WebSocket-Accept String (dXOwyU6vuIMy61iK64Xi0VrmyOQ=), anyway the WebSocket seems not to handle the handshake response. I tried debugging it with the Chrome Developer Tools, but I don't get usefull information from it.

I have this function correctly linked in an external .js file...
function SubmitAge(age, UpdatePanelID, HiddenAgeID) {
$get(HiddenAgeID).value = age;
__doPostBack(UpdatePanelID);
}
and am calling it like this from an onClick of an a href="#" ... html tag (tags removed, please scroll right as stackoverflow has the greatest difficulty in displaying simple content, 7th display related edit, thanks stackoverflow)
a href="#" onclick="SubmitAge(24, 'ctl00_MainContent_arFrom_upAgeRange', 'MainContent_arFrom_HiddenAge')" runat="server" 24 /a
yet, i am getting this error, and its being called on the first line of the SubmitAge function (line with $get(HiddenAgeID)... etc...)
Error:Microsoft JScript runtime error: 'null' is null or not an object
i've copied and pasted my WATCH windows in visual studio .net (vs2010 beta 2 using vb.net & c#) while the execution breaks inside teh SubmitAge .js function...
age 53 Number
UpdatePanelID "ctl00_MainContent_arTo_upAgeRange" String
HiddenAgeID Undefined identifier Error
Why on earth is HiddenAgeId, clearly passed just like UpdatePanelID, is returning an "Undefined identifier Error"???
edit: Update: turns out it works perfectly (as it should) when i load it up in FireFox, but has the resulting error in Internet Explorer, this is not a browser compatibility issue, it should also work in IE, but it doesn't!

my code is to handle the maxlength in the multiline textbox (textarea) so it works just like maxlength in the singleline text box , so I handled it onkeypress , but if I copy and paste , i want to substring the length to the maxlength from the clipboard , just to behave like the singleline textbox, the problem that the clipboard works only for the internet explorer but it doesn't work in other browsersso function in JScript.js.[code]

I am using Virtual Basic with ASP.NET in Visual Studio 2008. I am using Webmethod to communicate from/to the server with the client. Data can be queried and returned in small amount, but when I try get a relatively large amount of data, it's returning me a Server 500 error. My data is 226561 character long, so it's not that large, but it's relatively larger than my other working testing set, which are about 10k character long.
JavaScript:
PageMethods.my_func("context", success);
function success(result, userContext, methodName) {
[code]....
Is there anything I can change to increase WebMethod returned string length limit? Is there even a length limit or is it some other problem I could not see?

in my asp.net application, two buttons call a javascript function called refreshView, below is the function refreshView.
function RefreshView() {
__doPostBack('ButtonApply', '')
window.parent.location.href = "dashboardtree.aspx"
}
In IE, this is working correctly, but in firefox and safari the page refreshes (due to the window.parent.location) - but never calls the doPostBack (i was able to tell this using tracepoint and the sub that is called stores values to the database, the values are not being stored as well, sub is never hit). Below is the first line of the sub.
Private Sub ButtonApply_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ButtonApply.Click
Can anyone see why this would not work? I figured I could always replace the doPostBack with pageMethods and create a new sub/function - but I'd like to complete this the way it currently is.

I have a VB.NET function which looks like this:
<WebMethod()> _
Public Shared Function AuthenticateUser(ByVal UserInfo As String, ByVal Password As String) As Boolean
Dim UserName As String
[code]....
It calls the function, but won't return a value. When walking through the code, my VB function does fire (it will return true so long as the correct password is typed in), but the javascript 'authenticated' value remains 'undefined'. It's like you can't return values from VB functions to javascript.
I also tried
if PageMethods.AuthenticateUser("UserName", "Password")
{
//Stuff
}
But still no luck.

In my project, there are 3 user controls; BasicContact, BasicDetail and ActionTime. They are in EditOrder.aspx page. There is "ReportDate" property (Date type) in BasicContact, RadioButtonList "rdl_Priority" (with integer value from "prio_id" field) in BasicDetail and "CheckDate" property in ActionTime. The ReportDate value is derived from txt_ReportDate and txt_ReportTime and CheckDate value is derived from txt_CheckDate and txt_CheckTime.

So I have an .aspx page loading up and populating drop downs based on a lookup table in the database. What we want is for the user to be able to configure which of these values comes defaulted by specifying that value in a drop down somewhere else in the app. Now, it's easy to default the "first" value, or something like that, but we want this to act differently. Is there a JavaScript function that can run immediately after onLoad (so the drop downs are populated already), that can go through the drop down and make one of those default so it looks like the page is loading with that set as default and people don't realize the workaround? (weird masking, etc.)
Here is an example of how we add the dropdown control to the page:
With CType(.AddControl(New Controls.ComboBox("CodeId", "../../../../CodeId", "Code")), Controls.ComboBox)
.ForceSelection = True
.ValueField = "LookupID"
.DisplayField = "LookupDesc"
.Validate.AllowBlank = False
.ForceSelection = True
.ReadOnly = EditControl.IsFieldReadOnly(10580)
.BindData(Model.Codes)
End With
