Hooking A Javascript Function To Every Postback?

Aug 15, 2010

This is some Javascript added on an .aspx page:

<Head>
<script>
function SayHello()
{
alert('Hello');
}
</script>

and here is how I am calling it from code:

protected void Page_Init(object sender, Eventargs e)
{
Page.ClientScript.RegisterStartupScript(Page.GetType(),"script","SayHello()",true);
}

The problem is that the Javascript function is called only one time, on the very first page load. I want it to be called on every post back. for example on every button click

How To Run A Javascript Function Before Postback Of Button

May 27, 2010

I'm using Javascript to create a DIV element and open up a new page by using onclientclick. This works great. Now, I need to write to it from the server side and this element must be created before it is posted back.

How do I get the javascript to execute before the postback?

Currently, I have to press the button twice because the element doesn't exist to write too on the first click.

To be clear, I need this to execute before the "OnClick" of the button.

Update: It looks like the Javascript function is called before the postback but the element is not updated until I run the second postback.

Update: Unfortunately it is a bit more complicated then this.

I'm creating a div tag in javascript to open a new window. Inside the div tag, I'm using a databinding syntax <%=Preview%> so that I can get access to this element on the server side. From the server side, I'm injecting the code.

I'm thinking this may be a chicken-egg problem but not sure.

UPDATE!

It is not the Javascript not running first. It is the databinding mechanism which is reading the blank variable before I'm able to set it.

C# - How To Register A Javascript Function To Run With Every Postback

Mar 17, 2010

I have a treeview in a user control. I need to run a javascript function with every asynch postback to scroll the div it's in to the right position. I've got it working, but I think there has to be a "cleaner" way to do it. In the Page_Load function of the control, I have the following code. Is there a better way to do it?

ScriptManager.RegisterStartupScript(this.UpdatePanel1, this.GetType(), "key" + DateTime.Now.Ticks, "RestorePosition();", true);

For the benefit of anyone searching for this answer, here is what I finally did that worked. At the top of the ascx page, I have the following code:

<script type="text/javascript">
function pageLoad(sender, args) {
Sys.WebForms.PageRequestManager.getInstance().add_beginRequest(SavePosition);
Sys.WebForms.PageRequestManager.getInstance().add_endRequest(RestorePosition);
}
function SavePosition(sender, args) {
document.getElementById('hdnScrollSaver').value = document.getElementById('reportTreeViewdiv').scrollTop;
}
function RestorePosition(sender, args) {
document.getElementById('reportTreeViewdiv').scrollTop = document.getElementById('hdnScrollSaver').value;
}
</script>

And then I wrapped the treeview in a div tag as follows:

<div class="reportTreeView" id="reportTreeViewdiv">
<asp:TreeView ID="TreeView1" runat="server" OnTreeNodePopulate="TreeView1_TreeNodePopulate"
OnSelectedNodeChanged="TreeView1_SelectedNodeChanged" PathSeparator="|" SkinID="ReportTreeView" />
</div>

AJAX :: Call JavaScript Function After UpdatePanel Refresh (Partial PostBack) Is Completed

May 7, 2015

[URL] .... am using this functionality in my project and it is working very fine but i am facing very strange issue while using this.

The above functionality is not working when we place dropdownlist and textbox inside updatePanel and ModalPopupExtender

The .aspx page where i am using ModalpopupExtender and UpdatePanel for DropDownList and Textbox is below

<%-- *************************** MODAL POPUP EXTENDER ***************************************************** --%>
<asp:HiddenField ID="HiddenField3" runat="server" />
<asp:HiddenField ID="HiddenField4" runat="server" />
<cc1:ModalPopupExtender ID="ModalPopupExtender1" runat="server" PopupControlID="Div6" TargetControlID="HiddenField3"
BackgroundCssClass="modalBackground" CancelControlID="bclosemodalpopup" >
</cc1:ModalPopupExtender>

[Code] ....

The above code is not working with UpdatePanel but it is working if we remove DropdownList and Textbox from updatepanel.

The javascript code which i am using is below

<script type = "text/javascript">
var ddlText, ddlValue, ddl, lblMesg;
function CacheItems() {
ddlText = new Array();

How To Replace A Function Name Using JavaScript And Have It Be Recognized As A Function

Aug 25, 2010

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.

JavaScript - User Control JavaScript Function Doesn't Run

Sep 22, 2010

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...

Web Forms :: Hooking Dynamic Controls Inside An Updatepanel As An Asynctrigger To Another UpdatePanel?

Oct 7, 2010

I have two update panels and one javascript control.

When the javascript button is clicked, it forces a partial postback on UpdatePanel2. UpdatePanel2 is populated with dynamically created buttons that have javascript effects (jquery) but when click can also induce a postback. My problem is that, when clicking on these dynamic buttons, the whole page does not do a partial post back but rather UpdatePanel2 itself does a partial postback and everything is gone.

However, what I want to do is be able to tie each of the dynamic buttons in UpdatePanel2 (After being dynamically created) and make them an asychnonous triggers to UpdatePanel1. So that when clicking on these dynamic buttons, ONLY UpdatePanel1 is doing a partial postback refresh. UpdatePanel2 stays put and remains the same.

C# - Javascript Function Don't Run At Once?

Feb 13, 2011

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

How To Create A Javascript Function

Mar 17, 2010

I'm working on an MVC application and I ran into a little snag.

I've got a form with the usual textboxes and dropdowns. I decided to use jquery ajax (GET) to load the dropdowns on load (State Names & Salutations).

No matter what I try, for example:

Code:
<AcceptVerbs(HttpVerbs.Get)> _
Public Function ReturnSalutationDropdown() As ActionResult
Dim dropdown As New DropDownList With {.TabIndex = 1, .DataTextField = "Value", _
.DataValueField = "Key", .ID = "ddl_coSalutation"}
dropdown.DataTextField = "Value"
dropdown.DataValueField = "key"
dropdown.DataSource = AppEnumerations.BindToEnum(GetType(AppEnumerations.Salutation))
dropdown.DataBind()
Dim sb As New StringBuilder
Dim tw As New IO.StringWriter(sb)
Dim hw As New HtmlTextWriter(tw)
dropdown.RenderControl(hw)
Return Content(sb.ToString)
End Function

The ID of the dropdown ends up like: ctl00$MainContent$ddl_coSalutation

It doesn't matter if I use a stringbuilder and a loop to create a <select> with <option>'s, the ID always ends up like above.

Do I have to create a javascript function to create it instead?

C# - Javascript Function To Set Cookie Value?

Nov 8, 2010

I am new to programming and trying to write a javascript function to set a cookie value when a popup button is clicked.

In home.aspx

<input id="btnCanOK2" type="button" value="Close" class="popupButton" runat="server" onclick="return btnClose_Click" />

for this button, i have written a javascript function:

function btnClose_Click()
{
document.cookie = 'cookieName=closed; value=dontshowagain';
}

In merchant.login page

In the code behind of the other page, it has to check if the value of the cookie is set to "dontshowagain". If it is set to the value, the function should not show the popup again. My task is not to show the popup in different pages. If it is closed once, it has to stop showing again until the browser is closed.

if (Request.Cookies["closed"] == null)
{
ModalPopupextender2.Show();
}
else if(Request.Cookies["closed"].Tostring() == "dontshowagain")
{
ModalPopupextender2.Hide();
}

Where am i doing wrong?? Now Cookie value is always null :(
