When using dojox.av.FLVideo widget, I have encountered a problem where I can't destroy the widget manually. In simple logic:
1st AJAX call
[Retrieves a partial page A with video]
var videoDiv = document.createElement('div');
videoDiv.id = "vid";
mainContent.appendChild(videoDiv);
var newVideo = new dojox.av.FLVideo({initialVolume:.7, mediaUrl:'video/sample.flv', autoPlay:true, isDebug:true}, "vid");
//video plays and everything looks fine
2nd AJAX call [Get another partial page B to replace the video]
var oldVideo = dijit.byId('vid');
oldVideo.destroy(); //should destroy this widget but doesn't
For some reason this widget is not destroyed, causing a problem because by the time we go back to perform AJAX call and try to page A and video again, it throws the id already exists exception.
I also tried other funcions such us destroyRecursive(), disconnect() but none of them worked, does anyone know where the problem is?
Cheers
Peter
Try this:
var oldVideo = dijit.byId('vid');
oldVideo.destroy();
delete oldVideo;

I want to create a carousel, firstly I create a nested content then I added it on my homepage but when I called, it's not working.
#{
string carouselId = "mainCarousel";
IEnumerable<IPublishedContent> carousel = Model.Value<IEnumerable<IPublishedContent>>(carouselId); }
I got error like this object reference not set to an instance of an object. I tried many things but I failed to reach on solve. Btw I'm using v8.1.12.
I fixed this problem with this code;
var page = Umbraco.Content(Guid.Parse("eea1803b-f093-42f6-8483-b27df3323c2d"));
var carousel = page.Value<IEnumerable<IPublishedElement>>("mainCarousel");
I've read the tutorials to log into a website prior to scraping it, but it just ain't workin'. I constructed a HttpIdentity object, added it to the Identities collection, and processed the request, but the page returned to scrape was still the login page. There isn't a lot about this on their website and documentation. Here's my code for that:
var identity = new HttpIdentity
{
UseCookies = true,
NetworkUsername = _username,
NetworkPassword = _password
};
Identities.Add(identity);
Request(_uri, Parse, identity);
In the Parse method I get a Response object returned with a Status Code of 200, and the "WasSuccessful" property of Response is "true". It seems that I should be redirected to the page I was trying to access, but I'm just getting the login html.
Is there something I'm missing?
I wasn't able to find a solution using the Iron Web Scraper, but I was able to do it with ScrapySharp, which is a free utility, so it worked out. ScrapySharp is able to mimic a browser to a degree, so navigation and submitting forms is pretty easy.
var browser = new ScrapingBrowser();
var homepage = browser.NavigateToPage(_Uri); // login Uri
var form = homepage.FindForm("login"); // get form by name
form.Method = HttpVerb.Post;
form["username"] = "my_username"; // get form fields by id
form["password"] = "my_password";
var resultPage = form.Submit(); // login
var loggedInPage = browser.NavigateToPage(new Uri("https://path.to.target.page"));
And that's it. I'm not sure what the problem was with Iron Web Scraper. Maybe some ajax on the login page. In any case, this code is working for me now.
I have a problem with my modal events. None of them I tested worked.
I'm using Bootstrap 3.3.6 and I tested my code in a jsfiddle and everything is working well there.
Here's my js :
$('#delete').on('show.bs.modal', function(e) {
var title = $(e.relatedTarget).data('title');
var id = $(e.relatedTarget).data('id');
document.getElementById('id').value = id;
document.getElementById('title').innerHTML = title;
});
I have no errors in my console, the modal shows up but the event isn't fired. I've tried show, shown and loaded.
Thank you for your help
Before asking this question, I haven't tested the .modal('show) method.
I got an error and after few checkups it's because I had two different versions of Jquery.
Problem solved after removing one.
I'm a complete newbie at Dojo, and Adobe AIR, which is my target. I'm
trying to put some panes into an AccordionContainer like so:
var mainview = dijit.byId("mainview");
var rand = randomString();
var widg = gtd_create_entry_widget(rand)
air.trace(mainview);
air.trace(widg);
mainview.addChild(widg);
"mainview" is my AccordionContainer, and gtd_create_entry_widget() is:
function gtd_create_entry_widget(id) {
var entry = new dijit.layout.ContentPane();
entry.attr("id",id);
entry.attr("title","title "+id);
return entry;
}
The pane shows up in the container, with the correct id and title, and
no errors, however, if I try to add another pane, the next one shows
up too, but I get the error:
TypeError: Result of expression '_7' [undefined] is not an object.
I get the same error if I run
var mainview = dijit.byId("mainview");
mainview.destroyDescendants();
and also, only one pane is destroyed at a time, and I understand this
method should destroy all the children.
I can include full project code if required.
Thanks a lot

I'm not exactly sure if this is going to fix your problem, but you're supposed to use dijit.layout.AccordianPane (http://www.dojotoolkit.org/api/dijit/layout/AccordionPane.html) with the AccordianContainer.
i have to run following javascript through one of my method. But its not running
Whats wrong with the code.
private void fillGrid1()
{
GridView1.DataSource = myDocCenter.GetDsWaitingForMe(Session["UserID"].ToString());
HiddenField1.Value = { myDocCenter.GetDsWaitingForMe(Session["UserID"].ToString()).Tables[0].Rows.Count).ToString();
GridView1.DataBind();
String csname1 = "PopupScript1";
String csname2 = "ButtonClickScript1";
Type cstype = this.GetType();
// Get a ClientScriptManager reference from the Page class.
ClientScriptManager cs = Page.ClientScript;
// Check to see if the client script is already registered.
if (!cs.IsClientScriptBlockRegistered(cstype, csname2))
{
StringBuilder cstext2 = new StringBuilder();
cstext2.Append("<script type=\"text/javascript\"> ");
// You can add JavaScript by using "cstext2.Append()".
cstext2.Append("var count = document.getElementById('ctl00_ContentPlaceHolder1_HiddenField2');");
cstext2.Append("var count = '100';");
cstext2.Append("document.getElementById('sp2').innerHTML = count;");
cstext2.Append("script>");
cs.RegisterClientScriptBlock(cstype, csname2, cstext2.ToString(), false);
}
}
Your script tag is not properly closed.
Change
cstext2.Append("script>");
to
cstext2.Append("</script>");
On top of what adamantium said, your JS looks a bit strange. You seem to declare and set the count variable twice - did you mean to do this.
Following that, best thing to do, render the page then view source. is your JS getting rendered to the page? try and stick an alert in there... is it firing?
> cstext2.Append("var count =
> document.getElementById('ctl00_ContentPlaceHolder1_HiddenField2');");
I would use the ClientID property here. HiddenField2.ClientID
RegisterClientScriptBlock emits the script just after the <form> tag openning. Browser executes this script just after the tag openning as well but referenced elements are not processed yet at this time - browser cannot find them.
RegisterStartupScript method emits the script just before the <form> tag ending. Nearly all page elements are processed by the browser at this place and getElementById could find something.
