Reference An Anonymous JavaScript Function?
Apr 14, 2010
I'm trying to call a Page Method using a jQuery 'attached' event function, in which I like to use the closure to keep the event target local, as below, but page method calls declare several 'error' functions, and I would like to use one function for all of them. If, in the below code, I was handling an error and not success, how could I use my single, anonymous handler for all 3 error functions?
$(":button").click(function () {
var button = this;
PageMethods.DoIt(
function (a, b, c) {
alert(button);
});
});
This example passes an anonymous function for the success callback. There is only one of these. If I was passing an error callback, how could I use 'function (e, c, t)' for all 3 error callbacks?
ADDED: What I would like to do here is trigger an AJAX call whenever the user clicks a toggle button (checkbox), but to improve responsiveness, I want to toggle the button state immediately, and only 'untoggle' it if the AJAX call fails.
Now, in my client-side click() event handler, I would like to use anonymous functions inside the scope of click()' so that the functions have access to thethisevent argument, but I don't want to 'declare' three functions for theonTimeout,onError, and 'onAbort arguments of the PageMethods.MyFunction function. if I declare a named function outside of the click handler, it no longer has access to the 'this' parameter of the click() event handler.

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?

In my gridview I have fields for inserting a new record in the footer.
In my objectdatasource selecting event if no records came back I bind a single mock row to force the footer to show so they can still add records. Since the row does not contain real data I hide the row.

I am currently implementing a client-side paging solution using ASP.NET, jQuery and JSON.
I have been following the excellent article from encosia: http://encosia.com/2008/08/20/easily-build-powerful-client-side-ajax-paging-using-jquery/
In my Web Method I retrieve my data from the database as a DataTable:
DataTable categoryProducts = ProductViewerAccess.GetCategoryProducts
("AA", 4, 0, Page.ToString(), out howManyPages, "FALSE", 0, "CostPrice", "asc", destinationList);
I then retrieve the data from the DataTable into an anonymous type:
var feeds =
from feed in categoryProducts.AsEnumerable()[code]....
This all works great.
However, I would like to extend the code to perform some evaluation checks (e.g., check that various columns in the DataTable are not NULL) and other pre-processing (e.g., call various functions to build the image URL based on the image ID - which is another column in the DataTable not shown in the code fragment) before I return the resulting rows of the DataTable as an anonymous type to the client-side.Basically, I want to iterate through the DataTable, perform the evaluation checks and pre-processing, while building my anonymous type manually as I go. Or maybe there is a better way to achieve this?

I am trying to replace the JavaScript onclick event handler in ASP.NET that is added to a button control when using validation controls. This is what is output into the HTML from ASP.NET in this scenario:
<input type="image" name="ibSubmit1" id="ibSubmit1" src="button-green-submit.gif" onclick="showProgress1();WebForm_DoPostBackWithOptions(new WebForm_PostBackOptions("ibSubmit1", "", true, "Group1", "", false, false))" style="border-width:0px;" />
I have looked pretty estensively, and unfortunately there doesn't seem to be a way to modify the function server side before it is injected into the page.
Since I am developing a control and desire it to be non-invasive and self contained, and I am interested in obtaining the validationGroup parameter of the WebForm_PostBackOptions object, it seems that the easiest solution would be to use JavaScript to replace the WebForm_DoPostBackWithOptions function name with my custom wrapper function and leave all of the rest of the parameter information intact - then I can extract the information I am interested in, call my custom functions, and then forward the call on to WebForm_DoPostBackWithOptions.
NOTE: I am using jQuery to build my custom function, so if there is an easier way to do this with jQuery it is an option I will consider.
Here is the code I tried to replace the onclick event handler (not working):
$('[onclick*=WebForm_DoPostBackWithOptions]').each(function() {
var txt = this.onclick;
txt = txt + '';
txt = txt.replace('WebForm_DoPostBackWithOptions','ml_DoPostBackWithOptions');
this.onclick = eval(txt);
});
Using alert(), I verified that the text is being changed correctly, however whether or not I use the eval() function, the onclick handler doesn't seem to recognize it as JavaScript.
I thought of using a regular expression to get the validationGroup value, but this seems like it will be far more elegant and flexible if I can get it working...
Note: If there is a way for my control to interrogate the page it is on to find all of the buttons that will post back (regardless of what type of buttons they are) so I can retrieve the property server-side, this is also something I will consider.

How do you reference an asp.net control on your page inside a function or a class.
private void PageLoad(object sender, EventArgs e)
{
//An example control from my page is txtUserName
ChangeText(ref txtUserName, "Hello World");
}
private void ChangeText(ref HtmlGenericControl control, string text)
{
control.InnerText = text;
}
Will this actually change the text of the txtUserName control?
I tried this and is working
private void PageLoad(object sender, EventArgs e)
{
ChangeText(txtUserName, "Hello World");
}
private void ChangeText(TextBox control, string text)
{
control.Text = text;
}

I have the function put here like below:
$(document).ready(function () {
UserControlNameInit();
});
The script are put in the following and the block is in the .ascx page.
<script type="text/javascript">
</script>
However, the function UserControlNameInit() does not run when the page loads. It is showing in the page source. I can still call this function through FireBug console by manually typing the name of the function.
I did the same way with other user controls, and it works. Just 1-3 user controls are not working...

I've inherited some code (not mine- I swear!) which uses a session variable in the header of the HTML to determine which javascript file to link to.
<SCRIPT language="javascript" src="../JavaScript/<%=Session("jsFileName")%>.js"></SCRIPT>
It does work, except that it won't let me change to design view. It gives the message "Could not open in design view. Quote Values differently inside a '<%... "value" ...%>' block.

I have a hquery plugin that consists of jquery itself, 2 .js files and some script to configure the plug-in which resides on the page. I noticed that in .net you can create a .js file.What I would like to do is put the configuration inside a .js file created in .net, but how do I then reference this in the header of the page?am I over complicating the issue or just missing something?

I have some pages that reference javascript files.
The application exists locally in a Virtual Directory, i.e. http://localhost/MyVirtualDirectory/MyPage.aspx
so locally I reference the files as follows:
<script src="/MyVirtualDirectory/Scripts/MyScript.js" type="text/javascript"></script>
The production setup is different though. The application exists as its own web site in production, so I don't need to include the reference to the virtual directory. The problem with this is that I need to modify every file that contains a javascript reference so it looks like the following:
<script src="../Scripts/MyScript.js" type="text/javascript"></script>
I've tried referencing the files this way in my local setup but it doesn't work.

I am using Asp.Net C# 2.0. My website is working fine in local. Website contains 2 js files included in master page. It works fine in local environment, but when i publish my website i get "Object expected" error on page load, and thus the js functions are not working in published website.
Currently i am writing <script src="/javascripts/jquery.hotkeys-0.7.9.js" type="text/javascript"></script> in master page.

I'm sure I'm going about this wrong but I'm trying to write a simple javascript method that will set a hidden type value upon a link click. I'm using the Html.BeginForm() helper that contains two links similar to:
@Html.ActionLink("Delete Review Only", "Delete", new { id = Model.ReviewId }, new { onclick = "SetDeleteType(1);" })
<script language="JavaScript" type="text/javascript">
function SetDeleteType(selectedtype) {
document.supportform.deleteType.value = selectedtype;
document.supportform.submit();
}
The supportform name obviously doesn't exists since I'm using BeginForm() and can't specify a form name. Is there a clever way of doing this without calling Forms(0) using jQuery or something or am I completely off?

I wish to execute a javascript function in HTML Editor content. Hower, I give me the error "object expected". It seems like the browser cannot locate my javascript file.
Here is my setup:
- I have an external javascript file, "myscript.js" under "script" folder which has "test" function which contains a single "alert()" command.
- I referenced to "myscript.js" via <script src=....> tag (and also tried using Script manager's ScriptReference Path, same result).
- In my default.aspx page, I have a button which call "test" on mouseover event, which works call "test" correctly whenever I mouseover.
- In my default.aspx, I have the HTML Editor, with the this HTML content:
<span id="0001" onmouseover="alert('ok');">OK</span>
<span id="0002" onmouseover="test('not ok');">Not OK</span>
When I mouseover "ok" alert() script executed, but it give "object expected" error on I mouse over "not ok", it look like the browser cannot find "test" in myscript.js.
How do I reference this a script file inside the HTML Editor content?

I've some function javascript to check loaded file with FileUpload Control
<script language="javascript" type="text/javascript">
function CheckFileBeforeUpdate()
{
var filePath = document.getElementById('<%= this.upFile.ClientID %>').value;
var validExtension = 'xml';
var ext = filePath.substring(filePath.lastIndexOf('.') + 1).toLowerCase();
if (ext == validExtension) return true;
alert('The file extension ' + ext.toUpperCase() + ' is not allowed!');
return false;
}
</script>
and it's called with Button: OnClientClick="return CheckFileBeforeUpdate();
<asp:Button ID="LoginButton" runat="server" CommandName="Login" Text="Log In"
onclick="LoginButton_Click" OnClientClick="return CheckFileBeforeUpdate();" />
So there's unusual situation: I choose appropiate file, click Login...and it goes on to next functions despite inadequate extension.
Otherwise if I e.g. click FileUpload, but select no file.
Next time I choose some file (even with bad extension) and then function run (shows alert).
Why there's sth like blockade? What can I do to change CheckFileBeforeUpdate() runs everytime?
EDIT
if I select no file there's show alert("Select file to log in"); of course. And then is lock release
