Javascript - .NET Cross Domain Modal Window (window.showModalDialog) - Parameter Value Always "undefined"?
Aug 27, 2010I have two webpages, parent page .aspx and child page .html.
On parent page I have JavaScript function for invoking child page as modal window via window.showModalDialog.
function viewCourseModal(url) {
var sPars = SomeParameters();
var returnedValue = window.showModalDialog(url, "", sPars);[CODE]...
So when I launch parent window and invoke child modal window, parameter with "someValue" gets returned to the parent window (to modalReadyForTest control) upon clicking the button Button1.It works fine when I have both parent and child pages on the same domain. When I have them on different domains, value of the parameters does not get passed and instead it is always "undefined".Is there any way to have modal window from different domain returning parameter value to parent page? Can those cross domain issues be solved at all or should I try completely different approach?
Popup Needs To Refer Back To Textbox Within A Content Control / Window.opener.document.form1 Is Undefined
Sep 10, 2010I have a link that is located inside a content control. This link calls a javascript function that opens a popup window containing a calendar and passes it the transformed id from the server of a textbox control using clientid. I need to be able to click on a date and have the popup close and insert the date into the textbox of the id I passed into the function which again, is located inside the content control.
This is the link in the content control:

C# - Javascript Undefined Attribute - Why Source.full Is Always Undefined On The First Click
Nov 22, 2010I have a GridView with the following event:
protected void GridView1_RowCreated(object sender, GridViewRowEventArgs e)
{
foreach (TableCell c in e.Row.Cells)
{
c.Attributes.Add("full","false");
}
}
And in my javascript I have an onClick event for every cell:

source.full="true";
}
else

source.full="false";
}
Why is it that source.full is always undefined on the first click?
AJAX :: 'Sys' Is Undefined / 'WebForm_SaveScrollPositionSubmit' Is Undefined
Dec 22, 2010We have a site running FW 2.0 on IIS 6. Actually two sites (on the same server), one works and one has that little Done with errors note in the lower left. The errors are 'Sys' is undefined & WebForm_SaveScrollPositionSubmit' is undefined. I have cleaned the bad site, copied the code from the good site, including web.config, and still see the problem. This was working for a number of months, then I guess we didsomething, and now the errors.

Jan 12, 2011On "submitForms" click the fucntion "submitTest" is invoked. From jQuery documantation "submitHandler" would be called if form is VALID.

Javascript - XmlHttpRequest Sent Though ClientValidation Failed?
Jan 12, 2011I have many AJAX forms on the page and on button click I need to submit them all. Regular **forms.each(function (index, form) { $(form).submit();} won't work for me because in this way ONLY the last form will be submitted eventually. Therefore, I need submit them via $.ajax(...). But I want to enable submit ONLY and ONLY if form is VALID On "submitForms" click the fucntion "submitTest" is invoked.

Remove Cookie From XMLHttpRequest Object?
Jun 23, 2010I am making an ajax call with jquery like:
$.ajax({
url: "path/to/webservice.asmx"
beforeSend: function(xmlHTTPRequest) {
//modify headers here
//remove cookies
}
success: function() {
//do stuff
}
}
What I would like to do in the beforeSend function is take the incoming xmlHTTPRequest variable that is set and modify the headers to remove the cookie object that is in there, so in the call to my web service, it does not renew forms authentication in asp.net

View 3 RepliesInvoking WebMethods With XmlHttpRequest And Pure JavaScript?
Jun 22, 2010I have what should be a relatively simple task that's frankly got me stumped. I've researched it until my brain is fried, and now I'm puntingHere's the scenario:I have an ASPX page (Q2.aspx) that is decorated with the WebService,WebServiceBinding, and ScriptService attributes. That page contains a method, GetAllContacts, that is decorated with the WebMethodattribute and returns a string containing JSON data. (For what it's worth, the pageitself contains no other controls or functionality.)I have an HTML page that contains JavaScript which uses the XmlHttpRequestobject to invoke the GetAllContacts WebMethod on the ASPX page and transformthe JSON data into an HTML table. I have verified that my Web.Config file contains the appropriate protocol handlersfor HttpGet and HttpPut in the WebServices section under System.Web.webServices.
I have verified that my Web.Config file contains the ScriptModule entry under theSystem.webServer.modules section, and that it matches the appropriate documentation.
However, when I view the HTML page in a browser, the following occur:The web request goes through, but the results are for the unprocessed HTML from the ASPX page.The GetAllContacts method is never invoked, as evidenced by setting a breakpoint in its code.The code to invoke the Web service, however, is invoked, and the JavaScript callbackfunction that is invoked upon request completion is properly invoked.
It appears that the JavaScript code is largely set up correctly, but for some reason that is completely escaping me at this point, the HTML page will simply not execute the WebMethod on the ASPX page, and simply returns the page as though it were a plain HTML GET request. Clearly, an HTML document can't be evaluated by JavaScript's eval function, which brings me to my problem. (Also note that the JSON data appears nowhere in the HTML that's returned.)I am, frankly, baffled. I've looked at dozens of Microsoft articles, StackOverflow posts, CodeProject articles, and who knows what else. My code looks like it's okay. But I know better. I'm missing something simple, stupid, and obvious. I just need someone to point it out to me.Below you'll find the ASPX page code and the HTML code, in the hope that they'll shed some light.ASPX Code

C# - Use XMLHttpRequest To Execute A SQL Query And Return The Results?
Feb 9, 2011I'm building a web app for my company that will run a query every few seconds against SQL Server, and the data that it returns is which database is restoring and how much % complete it is. I have the query already set up and it works fine.
What I want to do is on my Web Form, have a "div" element that will contain the % complete of a database restore, and have it update every few seconds using the JavaScript timer object:
setInterval(function, interval)
I figure I would need to use XMLHttpRequest to send the request to the web server which will run the SQL query. Am I on the right track? How would I even start to do this?
My SQL query is below:
Use master
Select der.session_id, der.command, der.status, der.percent_complete, *
From sys.dm_exec_requests as der
Where percent_complete > 0

XMLHttpRequest - Send JSON From Mozilla Addon To Page
Apr 16, 2010I am trying to send JSON from my mozilla addon to my asp.net page.
var myJSONObject = {"userName": una,"password": pass};
request = new XMLHttpRequest();
request.open("GET","http://www.google.com?jo=" + myJSONObject,true, null, null);
on my .net page I have tried several ways of doing it but not able to find the best way to serialize and deserialize the code. All I need is to send the json data back n forth and parse it on C# n javascript.
I have tried DataContractJsonSerializer, JavaScriptSerilizer among many other things. But not able to make any of it work. With the JavaScriptSerilizer, It does deserilize it if it takes an argument from the browser for e.g. If I open up the browser and paste something like [URL]} it does deserilize and return me individual values, but it does work when I do an XMLHTTPRequest (as above) from my mozilla addon.

Javascript - Passing Data Between A Parent Window And A Child Popup Window With JQuery
Dec 3, 2010I have the following HTML
<tr>
<td class="label" valign="top">
Affiliate Party
</td>
<td class="field">
<input type="hidden" name="ctl00$MainContent$ExternalAccountAttributes$AffiliatePartyId" id="AffiliatePartyId" />
<input name="ctl00$MainContent$ExternalAccountAttributes$AffiliatePartyName" type="text" id="AffiliatePartyName" class="PartyLookup" />
</td>
</tr>
and the following Javascript/jQuery
$(".PartyLookup").after("<img src='Images/book_open.png' class='PartyLookupToggle' style='padding-left:4px;' />");
$(".PartyLookupToggle").click(function () {
window.open("PartySearch.aspx", "PartySearch", "width=400,height=50");
return false;
});
I need to be able to flag ANY PartyId input field with class="PartyLookup" so that it will modify the DOM and include the image next to the input field. The popup window returns data to populate both the hidden and text fields, but since the click() is generic I need to pass it the ID of the input field.

Web Forms :: Return True Or False From Popup Window To Parent Window
Sep 25, 2010I am trying to return true or false from popup window to the parent window. Actually the parent window has a button control, which on click popup another window. The popup window holds some emailing data and a button "send". This "send" button onclick send email. Now I want to return true if the email is successfully sent otherwise false, to the parent window. Depending on returning value a label present on parent window displays a text message. But I am not able to implement it. Because it might happen that the popup window is blocked by web-browsers popup blocker or popup window is accidentally closed by user. So how can I confirm to parent window whether or not the email is successfully sent?
