  • dropdowllist selected item from javascript to servlet

    - by kawtousse
    Hi, I am writing to ask if anybody knows, is it possible to get the value from a JavaScript variable and use this value in a Java Servlet? I have read up on this but all i have found is getting the JavaScript value through a form submit. What I need is: I have a html select combo box. I need to extract the selected value from this and use this value to query a database. Is this possible. Thanks in advance.

  • Back button causes iFrame to delay window.onLoad event

    - by JoJo
    I serve ads through an iFrame. The ad network's servers are much slower than mine, so I asyncronously load the iFrame after the window.onLoad event. Event.observe( window, 'load', function() { $('ad').writeAttribute('ad.html'); } ); A problem occurs when you enter the site via the browser's back button. Unexpectedly, the ad iFrame attempts to load immediately, delaying window.onLoad for a few seconds. During these few seconds, the site is unusable because I do a bunch of initialization after window.onLoad. As far as I know, this only happens in Firefox. How do I prevent this blocking load?

  • iPhone SDK audioSession question.

    - by Morion
    Hi to all. In my app i record and play audio at the same time. The app is almost finished. But there is one thing, that annoying me. When audio session is set to PlayAndRecord, sounds become quiet in comparison with the same sounds with the SoloAmbient category. Is there any way to make sound louder using PlayAndRecord?

  • Open a chrome tab from delayed javascript window.open

    - by jettero
    When I window.open("http://blarg") in chrome, I get a new tab. If I delay the open, say using a jquery $(hrm).animate({},5e3,function(){window.open(url)); it opens the url in a new window with no status bar, etc — if I give it permission to pop-up that is. I'm looking for a way to get the instant behavior, that is, I wish to open a URL after an animation, but still in a new tab. I imagine I could get by with learning a way to instruct chrome to never ever open pop-ups and to always open them in tabs (I imagine there's a webkit setting, why it's not a built in is a mystery); but I'd rather try to find a way to do it from the javascript if possible. I somewhat doubt there's any way to do this though. I'm not aware of any javascript that's tab-aware.

  • Changing function parameters for onkeypress event according to source id

    - by DarRay
    I want to assign a function according to their id to all the input fields in a webpage. To do i wrote below code but all the input fields are running keyPress with same parameter.. :( ///////////////////Checks all available 'text' 'input's//////////////////// var inputs = document.getElementsByTagName('input'); var cnvtrInput = new Array(); for (var index = 0; index < inputs.length; index++) { if (inputs[index].type == 'text') { cnvtrInput[index] = new converter(inputs[index]); inputs[index].onkeypress = function() {return keyPess(cnvtrInput[index])}; } } //index--; With the last commented statement i found that the passing element of keyPress is the last value of index; Finally i tried same with textareas but failed...

  • If you delete a DOM element, do any events that started with that element continue to bubble?

    - by Matt
    What behavior should I expect if I delete a DOM element that was used to start an event bubble, or whose child started the event bubble - will it continue to bubble if the element is removed? For example - lets say you have a table, and want to detect click events on the table cells. Another piece of JS has executed an AJAX request that will eventually replace the table, in full, once the request is complete. What happens if I click the table, and immediately after the table gets replaced by a successful completion of an AJAX request? I ask because I am seeing some behavior where the click events don't seem to be bubbling - but it is hard to duplicate. I am watching the event on a parent element of the table (instead of attaching the event to every TD), and it just doesn't seem to reach it sometimes.

  • Access ASP.NET control using javascript

    - by user3036965
    I have a basic javascript function like this which works as I am able to dynamically change the textbox in a javascript method at runtime. function MyTst(pVal2) { var x = document.getElementById('<%=myImage.ClientID%>'); x.src = "/images/write.gif"; } In the above code I need to be generic. So replace '<%=myImage.ClientID%' with the input param to my method which in this instance is called pVal2 and contains the asp.net server control image id. Can anyone advise on an approach to do this. I've tried lots of things and just cant seem to get it working. Thanks for any advice.

  • Remove Duplicates from JavaScript Array

    - by kramden88
    This seems like such a simple need but I've spent an inordinate amount of time trying to do this to no avail. I've looked at other questions on SO and I haven't found what I need. I have a very simple JavaScript array such as peoplenames = new Array("Mike","Matt","Nancy","Adam","Jenny","Nancy","Carl"); that may or may not contain duplicates and I need to simply remove the duplicates and put the unique values in a new array. That's it. I could point to all the codes that I've tried but I think it's useless because they don't work. If anyone has done this and can help me out I'd really appreciate it. JavaScript or jQuery solutions are both acceptable.

  • iPhone SDK Objective-C __DATE__ (compile date) can't be converted to an NSDate

    - by Janice
    //NSString *compileDate = [NSString stringWithFormat:@"%s", __DATE__]; NSString *compileDate = [NSString stringWithUTF8String:__DATE__]; NSDateFormatter *df = [[[NSDateFormatter alloc] init] autorelease]; [df setDateFormat:@"MMM d yyyy"]; //[df setDateFormat:@"MMM dd yyyy"]; NSDate *aDate = [df dateFromString:compileDate]; Ok, I give up. Why would aDate sometimes return as nil? Should it matter if I use the commented-out lines... or their matching replacement lines?

  • Jquery/Javascript gmail style stuff for message inbox, such as select all message using checkbox etc

    - by Psychonetics
    I am enjoying the fact that I'm here building a private message inbox for my website after building a full user signup/login and activation system when a few months ago I thought I wouldn't have enough patience to learn this stuff. Anyway to my question. I am currently building the private message inbox for my users and wondering if there are any jquery/javascript stuff I can use to make my inbox more like the gmail inbox. E.G. Gmail allows you to select all read messages or unread or starred or unstarred or none of the messages using a checkbox. I would like to add this kind of feature to my website and I'm sure the easiest way to achieve this would be using a jquery/javascript script. I would appreciate if someone could provide some links or info to where I can find several of these types of scripts to use with my inbox page. Thanks EDIT: Would also like to note that I would like the checkbox to be in a dropdown just like gmails.

  • iPhone SDK: App crashing when trying to scroll through table

    - by iPhone Developer
    I have a view controller with a table on it. When the app starts, it loads the first 5 visble cells. That works as expected.

  • Binding mousemove within mousedown function with jQuery

    - by colinjameswebb
    I am trying to bind a mousemove event to a div when the left mousebutton is down, and unbind when it is released. This code should be fairly self-explainatory. function handleMouseDown(e, sbar){ if (e.button == 0){ console.log(sbar); //firebug sbar.bind('mousemove', function(event){ handleMouseMove(event, sbar); }); } } function handleMouseUp(e, sbar){ sbar.unbind('mousemove'); } function handleMouseMove(e, sbar){ // not sure it this will work yet, but unimportant $(".position").html(e.pageX); } $(document).ready(function (){ var statusbar = $(".statusbar"); statusbar.mousedown(function(event){ handleMouseDown(event, this); }); statusbar.mouseup(function(event){ handleMouseUp(event, this); }); }); The important part of the HTML looks like this <div id="main"> <div class="statusbar"> <p class="position"></p> </div> </div> Firebug says that the bind methods are undefined on the variable sbar within handleMouseDown and handleMouseUp. The firebug console prints out <div class="statusbar"> for the line commented //firebug. I'm doing something wrong, probably when binding the mousedown and mouseup... but what?! I'm using jQuery v1.4.2, if that helps?

  • iPhone SDK math - pythagorean theorem problem!

    - by Flafla2
    Just as a practice, I am working on an app that solves the famous middle school pythagorean theorem, a squared + b squared = c squared. Unfortunately, the out-coming answer has, in my eyes, nothing to do with the actual answer. Here is the code used during the "solve" action. - (IBAction)solve { int legoneint; int legtwoint; int hypotenuseint; int lonesq = legoneint * legoneint; int ltwosq = legtwoint * legtwoint; int hyposq = hypotenuseint * hypotenuseint; hyposq = lonesq + ltwosq; if ([legone.text isEqual:@""]) { legtwoint = [legtwo.text intValue]; hypotenuseint = [hypotenuse.text intValue]; answer.text = [NSString stringWithFormat:@"%d", legoneint]; self.view.backgroundColor = [UIColor blackColor]; } if ([legtwo.text isEqual:@""]) { legoneint = [legone.text intValue]; hypotenuseint = [hypotenuse.text intValue]; answer.text = [NSString stringWithFormat:@"%d", legtwoint]; self.view.backgroundColor = [UIColor blackColor]; } if ([hypotenuse.text isEqual:@""]) { legoneint = [legone.text intValue]; legtwoint = [legtwo.text intValue]; answer.text = [NSString stringWithFormat:@"%d", hypotenuseint]; self.view.backgroundColor = [UIColor blackColor]; } } By the way, legone, legtwo, and hypotenuse all represent the UITextField that corresponds to each mathematical part of the right triangle. Answer is the UILabel that tells, you guessed it, the answer. Does anyone see any flaws in the program? Thanks in advance!

  • JavaScript data grid for millions of rows

    - by Rudiger
    I need to present millions of rows of data to users in a grid using JavaScript. I don't want the user thinking about viewing finite pieces of data; it should appear that all of the data is available. Rather than downloading all the data at once, small chunks are downloaded as the user comes to them (by scrolling, keying in row numbers, searching). The rows will not be edited through this front end, so read-only answers are acceptable. What JavaScript data grids are best for this kind of seamless paging?

  • Detect second tap on tableview cell iphone sdk

    - by neha
    Hi all, In my application, I'm expanding a tableview row when it's tapped. I'm using - (void)setSelected:(BOOL)selected animated:(BOOL)animated { [super setSelected:selected animated:animated]; if( selected == YES ) { [self expandRow]; } else { [self contractRow]; } height = [lblFeed frame].size.height + 75; } to achieve that. So when a row is tapped, this function automatically gets the signal of row tap and it sets the selected=YES. Now when I tap the same expanded row, it still sets selected=YES. I want to detect the second tap and contract the row. How shall I do that while using the same function?

  • Executing a jquery effect on demand. Is it possible?

    - by Chocol8
    I was looking the Highlight effect of Jquery's. That effect is really the one i would like to add in my webpage. By looking at the the source code, i noticed that the effect will be reproduced on user's click of the div. $("div").click(function () { $(this).effect("highlight", {}, 3000); }); In my webpage i have an ImageButton <asp:ImageButton ID="btnFavorite" runat="server" ImageUrl="~/Images/Favorite.png"/> I would love to perform the highlight effect to the div, when the user clicks on the image button. Is it possible? UPDATE: If it is possible, could i use something like "OnClientClick=" of the ImageButton, since the imagebutton controls are added dynamically to the webpage?
