how can I run $(document).ready(function () { ....
function inside the user controlI am dynamically load my use control,what I wanan do is that whenthe load usercontrol,register my some javascript function via ready function.
here is the my javascript inside the my usercontroler,
<script language="javascript" type="text/javascript">
//register this script when the page load
var MainFunction;
$(document).ready(function () {
MainFunction = function (Plaka) {
alert(Plaka);
}
});
</script>
and I amtring to call Main function via my button which is the sam place of the ready function inside the usercontroler.
<ext:Button runat="server" ClientIDMode="Static" ID="btnMusteriEkle" Text="Yeni müşteri ekle">
<Listeners>
<Click Handler="MainFunction(#{txtPlaka}.getValue())"> </Click>
</Listeners>
</ext:Button>
I am trying to call MainFunction(#{txtPlaka}.getValue()) like this but not working.I am getting the error MainFunction is not defined.
emmm noone help me??!
here is the solution I found;
inside the user control define this ,
$(document).ready(function () {
$('#btnEkle').click(myFunction); //binding button evet to function on the sam epage
});
secondlly ,define this function inside the main page.
function myFunction(Param1,Param2) {
alert(Param1+''+Param2);
}
I guess this work soemthing like this(Pls correct me if I am wrong).
first load main page with the registered function,
later when the loading user control first time run the
this part;$(document).ready(function () {,later ,this function registerd the button event.
button:
<ext:Button runat="server" ClientIDMode="Static" ID="btnMusteriEkle" Text="Yeni müşteri ekle">
<Listeners>
<Click Handler="myFunction(#{Param1}.getValue(),#{Param2}.getValue()
)"> </Click>
</Listeners>
</ext:Button>
**if u tried this making stupid asp.net button,all pages after fire event render again iu will get the undefine value.
as ext.net button liseners work diffeerent from asp.net button,as it doesnt need render all page again.

I have created an aspx page "Analyse.aspx", I want to pass an argument to this page when calling it on a button click of another page say 'Master.aspx' by-
OnClientClick="javascript:window.open('Analyse.aspx?Param=');"
how to do it?
"Could not load type" can happen due to various reasons and not because of popup. Try to call Analyse.aspx directly in your browser and make sure it works. To troubleshoot read Parser Error Message: Could not load type 'webmarketing'
UPDATE
Your code is not well formed.
Instead of
OnClick="javascript:window.open(Analyse.aspx?Param=""');"
must be
OnClick="javascript:window.open('Analyse.aspx?Param=');"
UPDATE #2
To wire a js code to js onclick event you should use the OnClientClick() event
<asp:Button ID="btnDeDupCheck" runat="server"
OnClientClick="javascript:window.open('PieChart.aspx?Param=');"
Text="De-Duplication Check" Visible="False" />
The OnClick() event is used to run a .net code.
UPDATE #3
To add values from asp.net controls you need to inject asp.net code. Read How to pass a value into a javascript function within an aspx page onClientClick or OnClientClick Javascript:confirm get value in textbox?
<asp:Button ID="btnDeDupCheck" runat="server"
OnClientClick="javascript:window.open('PieChart.aspx?Param=<%=txt1.ClientID%>');"
Text="De-Duplication Check" Visible="False" />
I finally got the it,successful executed code-
OnClientClick="javascript:window.open('Analyse.aspx?Param=');"
but my new query is how to pass parameter from current page to this new page 'Analyse.aspx',
say my parameter is - "txtPwd.text"
and how to catch the argument on pageload of Analyse.aspx
I am trying to invoke a server side method through JavaScript by first displaying a confirm message and then trigger a button click on the page to call the function. However, the .click() method doesn't seem to work. Any ideas?
<script type="text/javascript">
function confirmDelete() {
var button = document.getElementById("hiddenButton");
if (confirm("Are you sure you would like to delete the row")) {
button.click();
}
}
</script>
and the button is defined like follows
<asp:Button ID="hiddenButton" runat="server" onclick="showHiddenMessage" Text="hidden" width="100px" />
Everything that I have found suggest that it should. including here:
http://www.comptechdoc.org/independent/web/cgi/javamanual/javabutton.html
and here:
Call ASP.NET function from JavaScript?
var button = document.getElementById('<% =hiddenButton.ClientID %>');
Id of server side controls is different on client side. modify code as above and try.
Modify confirmDelete() method as below:
function confirmDelete() {
if (confirm("Are you sure you would like to delete the row")) {
__doPostBack(( 'hiddenButton', '' );
}
}
Take a look at the ClientIDMode property of a Button. Setting this to Static will cause the button to render with the ID you entered in to your ASP.NET code. https://msdn.microsoft.com/en-us/library/system.web.ui.control.clientidmode.aspx
<asp:Button ID="hiddenButton" runat="server" ClientIDMode="Static" onclick="showHiddenMessage" Text="hidden" width="100px" />
If you look at the generated HTML, you should see the ID of this button as hiddenButton which should allow your Javascript to work.
By default ClientIDMode value will be Inherit, and will include the NamingContainer within the ID. This means the ID of the rendered HTML will be something like Panel1_hiddenButton and your Javascript won't find it with the current code.
For reference:
Static - The ClientID value is set to the value of the ID property. If the control is a naming container, the control is used as the top of the hierarchy of naming containers for any controls that it contains.
Inherit - The control inherits the ClientIDMode setting of its NamingContainer control.
But why don't you use your javascript function with your button? I think it is better:
<script type="text/javascript">
function confirmDelete() {
if (confirm("Are you sure you would like to delete the row?")) {
return true;
}
return false;
}
And your button:
<asp:Button ID="hiddenButton" runat="server" OnClientClick="return confirmDelete();" onclick="showHiddenMessage" Text="hidden" width="100px" />
In this case if user will click OK button, your showHiddenMessage function will occur. Otherwise nothing will be happen.
All,
Environment: ASP.NET 2.0, AjaxToolkit build 1.0.20229.0, IE9
I am using $find() to find a behaviour of a call out extender so I can show explicitly using .show() method. Unfortunately, $find() returns null.
$find('my auto generated behvaiour Id').show();
FYI: The BehaviorID on the ValidatorCalloutExtender is generated using ClientID of the control (ClientID_ + "BehaviourID" <- is also what I use in my $find() function) because I have many instances of this control on the same page.
I looked at the rendered code and I can see JS to create that creates the behaviour:
Sys.Application.add_init(function() {
$create(AjaxControlToolkit.ValidatorCalloutBehavior ...
The $find() executes AFTER a postback in an UpdatePanel and returns always null.
EDIT (ADDED):
I created new page and below is the code, find() returns still null,- is there a bug in Ajax control tooklit for ASP.NET 2.0?
<body>
<form id="form1" runat="server">
<asp:ScriptManager ID="ScripManager1" runat="server" EnablePageMethods="True" >
</asp:ScriptManager>
<asp:TextBox runat="server" ID="txtInputField" />
<asp:RequiredFieldValidator runat="server" ID="valInput"
ControlToValidate="txtInputField"
ErrorMessage="ERROR STRING"
Display="none" /> <ajaxToolkit:ValidatorCalloutExtender runat="server" ID="extValInput" TargetControlID="valInput" BehaviorID="myID" />
<asp:Button runat="server" ID="btn" OnClick="btn_click" CausesValidation="True" />
<script type="text/javascript">
var obj = $find("myID");
alert(obj);
</script>
</form>
ADDED:
After observation in JS debugger, I realized that the validator callout extender only appears (is added dynamically to the DOM) when there's error, hence, if there's no error you cannot find it.
THE QUESTION NOW IS: How to reposition the call out extender baloon before displaying it? It is really catch 22, you can't access it when it is not displayed and when it is displayed, it is already to late because it displays in the wrong place.
The cause of the problem is that you try to find component before page completes component initialization. Try to access your editor in Sys.Application.add_load event handler. I tried the following code and everything works fine:
<script type="text/javascript">
Sys.Application.add_load(function() {
var obj = $find("myID");
alert(obj);
});
</script>
Edit:
To address your latest question: how you can reposition it. Callout ValidatorCalloutExtender uses PopupExtender to show it. So, you can try to bind to 'showing' and 'shown' events of the popup extender and then try to reposition callout.
<script type="text/javascript">
Sys.Application.add_load(function() {
var callouotComponent = $find("myID");
var popupBehavior = callouotComponent._popupBehavior;
popupBehavior.add_showing(function(){alert("I am showing");});
popupBehavior.add_shown(function(){alert("I was shown");});
});
</script>
Note: I didn't verify this code, but it can be used as start point.
Modified your code and verified, popup position is changing.
<script type="text/javascript">
Sys.Application.add_load(function () {
var callouotComponent = $find("myID");
//Below line is to init popup ballon, otherwise popup behaviour will return null
callouotComponent._ensureCallout();
var popupBehavior = callouotComponent._popupBehavior;
popupBehavior.set_x(100);
popupBehavior.set_y(100);
});
</script>
In my project I have created a menu list. When I click on a menu item it should load a given page into an iframe on same page. However, it is loading as separate page, not into the iframe. Why is this?
<script language="javascript" type="text/javascript" >
function changeFrm(NewSrc){
document.getElementById('middleiD').src = NewSrc;}
<asp:HyperLink ID="HyperLink6" runat="server" onClick='ChangeFrm("WebUserControl.ascx")'>Calendar</asp:HyperLink>
you need a return false; in your onclick event which tells the original click to stop bubbling
<asp:HyperLink ID="HyperLink6" runat="server" onClick='ChangeFrm("WebUserControl.ascx"); return false;'>Calendar</asp:HyperLink>
well, to stop duping, add that to you function:
function changeFrm(NewSrc){
document.getElementById('middleiD').src = NewSrc;
return false;
}
I've got UpdatePanel with Div
<telerik:RadAjaxPanel runat="server" ID="RadAjaxPanel1">
<div class="pnlFind" style="display:none;">
</div>
</telerik:RadAjaxPanel>
wanna use js for showing this div
<script type="text/javascript">
function pageLoad(sender, args) {
if (args.get_isPartialLoad()) {
$('.btAddUser').click(function () {
$('.pnlFind').show('slow');
$('.pnlFind').attr('display', 'block');
return false;
});
}
}
</script>
but after partial postback, I got div invisible again(right! restore DOM) How can I remember that div should be always visible after button click. Thanks
You have to inject javascript into the page to simulate the click event again. Page.RegisterClientScriptBlock or Page.RegisterStartUpScript should do it.
