  • Performance differences between iframe hiding methods?

    - by Ender
    Is there a major performance difference between the following: <iframe style="visibility:hidden" /> <iframe style="width:0px; height:0px; border:0px" /> I'm using a hidden iframe to pull down and parse some information from an external server. If the iframe actually attempts to render the page, this may suck up a lot of CPU cycles. Of course, I'd ideally just want to get the raw markup - for example, if I could prevent the iframe from loading img tags, that would be perfect.

  • Easiest way to create twitter-like status update widget

    - by culov
    I want a widget that allows users to add a request if that request hasnt already been added, or vote for a request if it has already been added. when a user adds a request, i want it to immediately appear as the first element of the list, like what would happen to your timeline if you made new tweet. ive tried to look for a jquery plugin that offers this functionality, but i was unsuccessful (maybe i couldnt think of the right terms to search for??). i dont have enough faith in my js skills to write this from scratch, so id rather find a template to start with. Thanks.

  • How can I pass checkbox onclick event to parent onclick ?

    - by Kim
    I a with an onclick event and , and inside it. When I click on the checkbox then the div-onclick event doesnt fire - I would like it to fire without having to dublicate the onclick onto the checkbox. <div id="id-tag" onclick="do()"> <span>text</span> <img src="pic.jpg" /> <input type="checkbox" name="mycheck" /> </div> I know the div-idtag but ideally would like to avoid specifying it inside the checkbox. Using another function call on the checkbox onclick to call the parent is NOT what I am looking for, like onclick="run_parent_onclick()" but this is okay (untested) onclick="this.parent.click()"

  • Vertical centering text (jQuery)

    - by Nimbuz
    <div style="width: 100px; height:50px; line-height:50px; overflow:hidden;"> <p>A short line</p> </div> <div style="width: 100px; height:50px; line-height:50px; overflow:hidden;"> <p>A really really really long line</p> </div> Wrapped text in the second example gets cut off because of the line-height:50px which should be 25px in this case. How do I use jQuery to find if theres single or multi-line text in an element? Thanks!

  • Using Javascript to flip flop a textbox's readonly flag

    - by Velika
    I have a frame with several radio buttons where the user is supposed to select the "Category" that his Occupation falls into and then unconditionally also specify his occupation. If the user selects "Retired", the requirement is to prefill "Retired" in the "Specify Occupation" text box and to disable it to prevent it from being changed. The Specify Occupation text box should also no longer be a tab stop. If the user selects a radio button other than Retired the Specify Occupation text box should be enabled and once again in the normal tab sequence. Originally, I was setting and clearing the disabled property on the Specify occupation textbox, then I found out that, upon submitting the form, disabled fields are excluded from the submit and the REQUIRED validator on the Specify Occupation textbox was being raised because the textbox was being blanked out. What is the best way to solve this? My approach below was to mimic a disabled text box by setting/resetting the readonly attribute on the text box and changing the background color to make it appear disabled. (I suppose I should be changing the forecolor instead of teh background color). Nevertheless, my code to make the textbox readonly and to reset it doesn't appear to be working. function OccupationOnClick(sender) { debugger; var optOccupationRetired = document.getElementById("<%= optOccupationRetired.ClientId %>"); var txtSpecifyOccupation = document.getElementById("<%= txtSpecifyOccupation.ClientId %>"); var optOccupationOther = document.getElementById("<%= optOccupationOther.ClientId %>"); if (sender == optOccupationRetired) { txtSpecifyOccupation.value = "Retired" txtSpecifyOccupation.readonly = "readonly"; txtSpecifyOccupation.style.backgroundColor = "#E0E0E0"; txtSpecifyOccupation.tabIndex = -1; } else { if (txtSpecifyOccupation.value == "Retired") txtSpecifyOccupation.value = ""; txtSpecifyOccupation.style.backgroundColor = "#FFFFFF"; txtSpecifyOccupation.readonly = ""; txtSpecifyOccupation.tabIndex = 0; } } Can someone provide a suggest for the best way to handle this scenario and porovide a tweek to the code above to fix the setting/resetting on the readonly property?

  • Using Window Handle to disable Mouse clicks and Keyboard Inputs using P/Invoke

    - by srk
    I need to disable the Mouse Clicks, Mouse movement and Keyboard Inputs for a specific windows for a Kiosk application. Is it feasible using .NET ? I have removed the menu bar and title bar of a specific window, will that be a starting point to achieve the above requirement ? The code for removing the menu bar and title bar using window handle : #region Constants //Finds a window by class name [DllImport("USER32.DLL")] public static extern IntPtr FindWindow(string lpClassName, string lpWindowName); //Sets a window to be a child window of another window [DllImport("USER32.DLL")] public static extern IntPtr SetParent(IntPtr hWndChild, IntPtr hWndNewParent); //Sets window attributes [DllImport("USER32.DLL")] public static extern int SetWindowLong(IntPtr hWnd, int nIndex, int dwNewLong); //Gets window attributes [DllImport("USER32.DLL")] public static extern int GetWindowLong(IntPtr hWnd, int nIndex); [DllImport("user32.dll", EntryPoint = "FindWindow", SetLastError = true)] static extern IntPtr FindWindowByCaption(IntPtr ZeroOnly, string lpWindowName); [DllImport("user32.dll")] static extern IntPtr GetMenu(IntPtr hWnd); [DllImport("user32.dll")] static extern int GetMenuItemCount(IntPtr hMenu); [DllImport("user32.dll")] static extern bool DrawMenuBar(IntPtr hWnd); [DllImport("user32.dll")] static extern bool RemoveMenu(IntPtr hMenu, uint uPosition, uint uFlags); //assorted constants needed public static uint MF_BYPOSITION = 0x400; public static uint MF_REMOVE = 0x1000; public static int GWL_STYLE = -16; public static int WS_CHILD = 0x40000000; //child window public static int WS_BORDER = 0x00800000; //window with border public static int WS_DLGFRAME = 0x00400000; //window with double border but no title public static int WS_CAPTION = WS_BORDER | WS_DLGFRAME; //window with a title bar public static int WS_SYSMENU = 0x00080000; //window menu #endregion public static void WindowsReStyle() { Process[] Procs = Process.GetProcesses(); foreach (Process proc in Procs) { if (proc.ProcessName.StartsWith("notepad")) { IntPtr pFoundWindow = proc.MainWindowHandle; int style = GetWindowLong(pFoundWindow, GWL_STYLE); //get menu IntPtr HMENU = GetMenu(proc.MainWindowHandle); //get item count int count = GetMenuItemCount(HMENU); //loop & remove for (int i = 0; i < count; i++) RemoveMenu(HMENU, 0, (MF_BYPOSITION | MF_REMOVE)); //force a redraw DrawMenuBar(proc.MainWindowHandle); SetWindowLong(pFoundWindow, GWL_STYLE, (style & ~WS_SYSMENU)); SetWindowLong(pFoundWindow, GWL_STYLE, (style & ~WS_CAPTION)); } } }

  • Java RegExp ViewState

    - by CDSO1
    I am porting some functionality from a C++ application to java. This involves reading non-modifiable data files that contain regular expressions. A lot of the data files contain regular expressions that look similar to the following: (?<=id="VIEWSTATE".*?value=").*?(?=") These regular expressions produce the following error: "Look-behind group does not have an obvious maximum length near index XX" In C++ the engine being used supported these expressions. Is there another form of regexp that can produce the same result that can be generated using expressions like my example as input?

  • Google Analytics Widget Tracking

    - by Kevin Lamb
    Hello, I have a form that is generated on a customer's website (lets say customer.com) with javascript that a user fills out and it sends to my site (app.com). I would like to be able to provide information to the customer such as how effective their AdWords campaign was and what search engines users used to end up filling out the form. I have started looking at the multiple domain linking option but I am not sure this is the right way. Is there a way to query what search engine and key words they used and pass this along with the form?

  • How Do I Create A Accordian Box Using JavaScript?

    - by user105033
    Hi, what I want is this: Start: End: ---------------- ---------------- |asdf | | | ---------------- | stuff | | | | | ---------------- | asdf | ---------------- When you click asdf it should end up looking like the End box but the 'stuff' box should appear gradually so it looks like the asdf box is pulling down the stuff menu. When asdf is clicked again it should look like the stuff box is pulling up the asdf box and end at the Start position. Any tutorials on doing things like this?

  • Why would this div have an unnecessarily large computed height?

    - by Mike Crittenden
    Link: http://www.fraynepainting.com/services The problem is that div#dditem_2 (the div with the "Take a look..." text) is getting a computed height of around 500px for no reason that I can find in the CSS, which is pushing the UL below it down really really far. I discovered that if you set display: none or position: absolute (or anything else that removes it from the flow of elements) on the sidebar, then the bottom UL moves up like it should, so it looks like maybe the UL is trying to clear the sidebar, but I can't figure out why that would be either. I've reproduced the problem in Firefox and Chrome so far. Any ideas?

  • CSS doesn't apply to dynamically created elements in IE 7?

    - by Austin Hyde
    In the project I am working on, I dynamically generate (with javascript) filters that look like this: <div class="filter"> <a ... class="filter_delete_link">Delete</a> <div class="filter_field"> ... </div> <div class="filter_compare"> ... </div> <div class="filter_constraint"> ... </div> <div class="filter_logic"> ... </div> </div> And I have CSS that applies to each filter (for example): .filter a.filter_delete_link{ display:block; height:16px; background: url('../images/remove_16.gif') no-repeat; padding-left:20px; } However, it seems in IE 7 (and probably 6 for that matter), these styles don't get applied to the new filters. Everything works perfectly in Firefox/Chrome/IE8. Using the IE8 developer tools, set to IE7 mode, the browser can see the new elements, and can see the CSS, but just isn't applying the CSS. Is there a way to force IE to reload styles, or perhaps is there a better way to fix this?

  • Apache .htaccess

    - by Peter
    Hi! I have a htaccess problem. My directory structure look like this: / HEADER.html README.html /stackoverflow/ /stackoverflow/.htaccess .htaccess ServerSignature Off Options +Indexes HeaderName /HEADER.html IndexIgnore HEADER.html ReadmeName /README.html IndexIgnore /README.html IndexOptions +FancyIndexing AddCharset UTF-8 .txt IndexIgnore *.xml IndexIgnore *.php My primary directory is /stackoverflow/, when I navigate to this directory via browser I have included HEADER.html and README.html on every site/directories under /stackoverflow/, this works fine. I added some php code to my HEADER.html (which is in the root directory / ), I am trying to add to htaccess: AddType application/x-httpd-php .html .php .htm This not working, I think because the HEADER.html is in the root. If I try add the AddType... to the /.htaccess (and not to the /stackoverflow/.htaccess) it is overwriting my /stackoverflow/.htaccess rules. Why? How I can add AddType rule to my /stackoverflow/.htaccess to Apache parse html file as php file?

  • Positioning DIV's with Javascript

    - by Andrew P.
    I have two divs that I need to position horizontally dependent on the width of the user's screen. I've styled their vertical position in CSS, and I am trying to position them horizontally using Javascript. My divs: <div id="tl"> blah blah </div> <div id="bl"> blah blah </div> My CSS: #tl { position: absolute; top: -14px; right: 0; } #bl { position: absolute; bottom: 1px; right: 0; } My Javascript: var tl = document.getElementById('tl'); var bl = document.getElementById('bl'); var wide = parseInt(screen.width); var nudge = wide*.86; nudge = nudge+21; tl = tl.style; tl.right = ( parseInt(tl.right) + nudge ); bl = bl.style; bl.right = ( parseInt(bl.right) + nudge ); However... nothing happens. No errors, and definitely no movement from my divs. What am I doing wrong? Can anyone help?

  • Position text in top of a dinamically generated map area of type poly

    - by Guillermo Vasconcelos
    Hi, I have a web page with a dynamically generated image map (from a server side charting tool that I have no control over). I have a value for each area in the title attribute that I want to display on top of the image. I could dynamically generate span elements with absolute positioning, but I'm not sure how to calculate the "center" of a poly shaped area to use as coordinates. Is there an easy way to create texts for image map areas? a JQuery plug in perhaps? Do you know a good way to calculate the center of a poly area? Do you have any other suggestions? Thanks, Guillermo
