Am unable to understand why Cannot the below javascript code is not called from code behind
I have a simple javascript block like this
function callsCox(res) {
alert(res);
}
From my code behind :
....
string res="COX23";
string script = String.Format("callsCox({0})", res);
this.Page.ClientScript.RegisterStartupScript(this.GetType(), "Cox",script,true);
Am I missing anything? There aren't any exceptions or errors.
Page.ClientScript.RegisterStartupScript looks OK to me (might have missed something). Things to try
Add apostrophes to the call - it's coming through as an object. Try as a string
string script = String.Format("callsCox('{0}')", res);
Is the string script Page.ClientScript.RegisterStartupScript being called after an update panel partial postback. That could effect it
I have know functions not been found if they are in the same page. Try moving to an external js file. Don't asked me why this has resolved issues but it has a couple of times in the past for me.
Just for debug purposes take the function out of the equation all together, Try to get the alert working like this. It will at least isolate the problem if it does work
this.Page.ClientScript.RegisterStartupScript(this.GetType(), "Cox","alert('Does this work?')",true);
View the source of the page. Is the function even written into the page (or alert from point 4). It should be. If you put a breakpoint on the this.Page.ClientScript.RegisterStartupScript method is it being hit? Seems like it might not be.
Apologies for not giving you a 'hey this is the solution' type of answer. I've had stuff like this in the past and I've found it a matter of stripping things down until the problem has been isolated. Someone else may be able to spot an immediate problem of course. Good luck.
This works for me:
public static void ShowAlert(Page page, String message)
{
String Output;
Output = String.Format("alert('{0}');",message);
page.ClientScript.RegisterStartupScript(page.GetType(), "Key", Output, true);
}

We have an EPiServer (forms) edit view with a number of tabs. The customer has requested that the tab which is #2 (called "alternative content"), should be automatically selected under certain conditions when the editors open the edit-page. We don't want to reorder the tabs. How can this be accomplished? We're running EPiServer 11.
Update:
I've tried to accomplish this using a Dojo-script. The result in EPiServer depends on how I set it up, which is kinda strange to me in this case. Here's the file
Web\modules\CMSDefaultTabSelector\module.config:
Here's how it's called in ModifyMetadata:
...and the script itself, CMSDefaultTabSelector.js, looks like this:
The result, depending on whether you send in EditLayoutContainer, Dialog, or skip it entirely (the way it should look), is as follows:
Result with EditLayoutContainer
Result with Dialog
The result as it should be
If I try to skip this parameter, I get the error "ctor is not a constructor". Other layout elements just render an empty tab, weirder errors, or you get other error messages. If I use require([...]), the function is called on every page reload, which is not what I want. I want it to only be called whenever the code from ModifyMetadata kicks in. Hope someone can help.
After fiddling around for quite a while, I finally found the magic code. Since other people might also wonder how this is done, here's how it was solved in the end (using Dojo):
define([
"dojo/_base/declare",
"epi/shell/layout/SimpleContainer"
],
function (
declare,
SimpleContainer
)
{
return declare([SimpleContainer], {
//constructor: function () {},
postCreate: function () { /* PostCreate fires too soon, and the tab strip is not completely rendered */ },
startup: function () {
// Use Jquery to select the tab we manually want to change to, and click it:
var tabElement = $("div.dijitContentPane span.tabLabel:contains('Additional content')");
if ($(tabElement).length) {
$(tabElement).trigger("click");
}
}
});
}
);
I have a code in which I am calling the javascript function from the cs(codebehind) file using the ScriptManager.RegisterStartupScript method.
Though, this works in Google Chrome and Internet Explorer, it doesn't work in Firefox (even the latest one FF 61). But, when i replace the function name with the whole function as it is, it works in Firefox.
I have tried using all the possible alternatives Page.ClientScript, ClientScriptBlock, RegisterStartupScriptBlock etc., only in vain.
Kindly help me.
P.S: I hope I made my question clear.
Check that your javascript function call is being launched when your page has been rendered completly.
The script you are registering in
ScriptManager.RegisterStartupScript
Should be decorated inside a snippet like this:
string script= #"window.onload = function(){
// your call to the function...
};"
I dont know if it is even possible, but is there some way how to "end" page in Windows Phone 8 app?
My problem is that i am using one delegate (to know when is my xml downloaded) on multiple pages. It works fine, but when i open one page, she initialize herself, i go on other page (trough back button) and new page initialize herself too. Everything is fine, but the previous page is still listening to the delegate and it is really big problem. So i need to get the previous page (that closed) into a same state like she was not ever opened.
I will be thankful for any advice (maybe i am thinking in wrong way now, i dont know, maybe the page just have to be de-initialize).
PS: If its necessary i will post the code, but i think it is not. :)
Okey here is some code:
In class whis is downloading XML i have delegate like this:
public delegate void delDownloadCompleted();
public static event delDownloadCompleted eventDownloadCompleted;
This class is downloading few different xml files depends of constructor in run(int number) method.
After is download complete and all information from xml are saved in my local list i call delegateCompled. if (eventDownloadCompleted != null)
{
eventDownloadCompleted();
}
Then i have few different pages. All pages are used for display specific data from downloaded xml. So on this specific page I have method that is fired when "downloadClass" says it is complet.
XML_DynamicDataChat.delDownloadCompleted delegMetoda = new XML_DynamicDataChat.delDownloadCompleted(inicialiyaceListu);
XML_DynamicDataChat.eventDownloadCompleted += delegMetoda;
This is that "inicializaceListu" method:
private void inicialiyaceListu()
{
Dispatcher.BeginInvoke(() =>
{
model = new datka();
// object model is just model where i am saving all specific list of informations that i got from xml files.
chatList9 = model.getChat(1);
gui_listNovinky.ItemsSource = chatList9;
gui_loadingGrid.Visibility = Visibility.Collapsed;
});
}
All of these works fine, but when i go back (with back button) and open other specific page with other specific information from other downloaded xml, previous page is still listening for the delegate and inicialiyaceListu() method is still fired everytime i complete download of xml.
So i need to say previous page something like: "hey page, you are now closed! Can you shut the **** up and stop work?!?"
I think that specific delegate for each pages could solve this, but it is not correct programing way.
I solved it nice and easy. It is really simple solution. I just created bool variable and set it false when i go back. In inicializaceListu() i have condition if it is true. If it is true do that stuffs when false do nothing.
I have made a change to a method used in a Functiod in a mapping file but it seems the new code is not taking effect, ever.
I have deployed properly, started the application, restarted related host instance (actually all host instances I could find) and still, the old code seems to execute.
Here's the, simple, method:
public string RemoveNonNumericChars(string stIn, int maxLength)
{
string strOut;
try
{
strOut = Regex.Replace(stIn, "[^0-9]", "");
System.Diagnostics.EventLog.WriteEntry("BizTalk Server 2009", strOut);
return strOut.Substring(0, maxLength);
}
catch
{
return string.Empty;
}
}
I added the writing to EventLog line to see that this code is indeed being executed, but I don't get anything in "Application" event logs.
I do NOT get an empty string being returned, so it really does seem like the old code that's being executed prior to me fixing the method.
What am I missing exactly ?
Thank you.
For some reason, the script is not able to correctly retrieve the Build Config selected in Visual Studio, it's taken from Debug when I'm actually trying to build it for a Test environment. I should have known, thanks anyways.
If anyone can help me I'd appreciate it.
I'm working on a C# file in Visual Studio 2010 that I need to be able to test a website with multiple form pages, for the purpose of an example we'll refer to them all as 1.aspx, 2.aspx etc.
I've my code that fills out the first page (1.aspx) fine, and click the "continue" button to load the next page, but when it gets to 2.aspx it won't continue to fill out the form.
We'll say an element on the 2.aspx page is called "DOB". On trying to run from the start (I've all the pages form data in the one .cs file) I get an error like "DOB does not exist in the current context".
Anyone's insight into this would be really appreciated!
In all honesty, it sounds like you might be better off using the WatiN Framework. I have been writing automation with it for years and the way that it is implemented and its ease-of-use make it worth the slight learning curve.
Just to add a bit more to the answer; and yes, this is pseudo-code:
[Test]
public void Should_attach_to_browser()
{
ExecuteTest(browser =>
{
browser.GoTo(NewWindowUri);
browser.Link(Find.First()).Click();
var findBy = Find.ByTitle("New window");
var newWindow = Browswer.AttachTo(browser.GetType(), findBy);
newWindow.Close();
});
}
In the code above, note the Browser.AttachTo(browser.GetType(), findBy); method. Based on what I have understood of your question, the .AttachTo() method would work well since you would be able to take the focus off the current form and assign it to the next in your work/execution flow.
