  • How to set labels inside textfields for username and password like facebook?

    - by NAVEED
    I have a login form for my website. This login form have two text fields, username and password. Currently I am placing labels(username, password) just before textfields. But now I want to removed these two labels and want to show text(username, password) inside textfield. When user focuses on these textfields then texts should be removed and user can enter his desired username and password. I have also noticed that when user open a login form then font color of text(username, password) populated in textfield(username, password) is of diffent color and when user start typing in that field then previous text is removed and new font color is black. How is it possible?

  • Calling methods within same Javwscript class [Prototype]

    - by eldeejay
    I've created a class in Javscript using the prototype Class.Create complete with the initialize function and a few other functions. However, in one of my functions I want to reference another function in the same class, but cannot seem to get the syntax correct. e.g. var sampleClass = Class.create({ initialize: function(){ //do the init work here }, functionA: function(){ //do some more stuff here } functionB: function(){ //Do some stuff functionA() } } I've tried calling functionA() , this.functionA() but nothing works I just get errors. I know how to call the functions externally when the class has been instantiated, but not reference a function from within the class itself. Thanks

  • JS Url GET vars - problem with encoding

    - by Martin
    Hey there! I'm having a bit of trouble here and I was hoping someone throws me a hint :) I'm getting some GET VARS with JS but I have trouble with non-latin charsets: cyrillic for example. The cyrillic var appears correct in the url but when I retrieve it with JS I get some dummy string. I was wondering of a function similar to "unescape" for such a case. Alternatively, if someone knows a way I could convert a cyrillic string to the same dummy string I get from the URL, it will still do me the trick, since all I need is compare. :) Thanks! Martin

  • Nav drop down with rounded corner troubles...

    - by Jonah1289
    Hi I have worked on the following nav drop down seen here http://charmcitykids.missionmedia.net/. It works and is almost complete, but I have one issue. When you mouseover a nav title the text goes from color to black and then shows the dropdown. That is how it should work, but when you move your mouse to go a nav title within the dropdown the black text(active image) goes back to color and doesnt remain black. Any suggestion when dropdown is active and user is navigating through such to keep the text(active image) black? thnx jonah

  • Why is Chrome miscalculating jQuery submenu dimensions?

    - by chunkymonkey
    I'm trying to implement this dropdown menu with flyouts: http://jsfiddle.net/chunkymonkey/fr6x4/ In Chrome certain categories can be expanded to show their subcategories while others show nothing when opened up. For example: Alternative Rock can be expanded to show its multiple subcategories . . . BUT . . . World Music, which has as many subcategories, shows no subcategories when expanded. (SCREENSHOT: http://i.imgur.com/0WorR.jpg) I thought I had tracked this problem down to a problem with they way the dimensions of the dropdown elements are calculated in the original code: First change: - var newLeftVal = - ($('.fg-menu-current').parents('ul').size() - 1) * 180; + var newLeftVal = - ($('.fg-menu-current').parents('ul').size() - 1) * container.width(); Second change: Remove: var checkMenuHeight = function(el) { if (el.height() > options.maxHeight) { el.addClass('fg-menu-scroll') }; el.css({ height: options.maxHeight }); }; Add: var checkMenuHeight = function(el) { var max_height = options.maxHeight - breadcrumb.getTotalHeight(); if (el.height() > max_height) { el.addClass('fg-menu-scroll'); el.height(max_height); topList.height(max_height); } else { if (topList.height() < el.height()) { topList.height(el.height()); } } }; But it's still not working only on Chrome (version 8, Windows & Mac) (not sure why Chrome is different).

  • Difference between arguments in setInterval calls

    - by Martin Janiczek
    What's the difference between these setInterval calls and which ones should be used? setInterval("myFunction()",1000) setInterval("myFunction",1000) setInterval(myFunction(),1000) setInterval(myFunction,1000) My guess is that JS uses eval() on the first two (strings) and calls the latter two directly. Also, I don't understand the difference between the calls with and without parentheses. The ones with parentheses call it directly and then periodically call its return value?

    Tried doing http://davidwparker.com/2008/09/17/site-wide-announcements-in-rails-using-jquery-jgrowl/ Am really bad with JS. Think I am messing up on the last part where it says "This code goes in your application.js file (somewhere in $(function){ //here })" Am I not suppose to do a link_to_function and create a function with this code that references that link? Really lost on this one.

  • Hotkey to toggle checkboxes does opposite

    - by Joel Harris
    In this jsFiddle, I have a table with checkboxes in the first column. The master checkbox in the table header functions as expected toggling the state of all the checkboxes in the table when it is clicked. I have set up a hotkey for "shift-x" to toggle the master checkbox. The desired behavior when using the hotkey is: The master checkbox is toggled The child checkboxes each have their checked state set to match the master But what is actually happening is the opposite... The child checkboxes each have their checked state set to match the master The master checkbox is toggled Here is the relevant code $(".master-select").click(function(){ $(this).closest("table").find("tbody .row-select").prop('checked', this.checked); }); function tickAllCheckboxes() { var master = $(".master-select").click(); } //using jquery.hotkeys.js to assign hotkey $(document).bind('keydown', 'shift+x', tickAllCheckboxes); This results in the child checkboxes having the opposite checked state of the master checkbox. Why is that happening? A fix would be nice, but I'm really after an explanation so I can understand what is happening.

  • Ajax long polling (comet) + php on lighttpd v1.4.22 multiple instances problem.

    - by fibonacci
    Hi, I am new to this site, so I really hope I will provide all the necessary information regarding my question. I've been trying to create a "new message arrived notification" using long polling. Currently I am initiating the polling request by window.onLoad event of each page in my site. On the server side I have an infinite loop: while(1){ if(NewMessageArrived($current_user))break; sleep(10); } echo $newMessageCount; On the client side I have the following (simplified) ajax functions: poll_new_messages(){ xmlhttp=GetXmlHttpObject(); //... xmlhttp.onreadystatechange=got_new_message_count; //... xmlhttp.send(); } got_new_message_count(){ if (xmlhttp.readyState==4){ updateMessageCount(xmlhttp.responseText); //... poll_new_messages(); } } The problem is that with each page load, the above loop starts again. The result is multiple infinite loops for each user that eventually make my server hang. *The NewMessageArived() function queries MySQL DB for new unread messages. *At the beginning of the php script I run start_session() in order to obtain the $current_user value. I am currently the only user of this site so it is easy for me to debug this behavior by writing time() to a file inside this loop. What I see is that the file is being written more often than once in 10 seconds, but it starts only when I go from page to page. Please let me know if any additional information might help. Thank you.

  • Detecting whether user stayed after prompting onBeforeUnload

    - by Daniel Magliola
    In a web app I'm working on, I'm capturing onBeforeUnload to ask the user whether he really wants to exit. Now, if he decides to stay, there are a number of things I'd like to do. What I'm trying to figure out is that he actually chose to stay. I can of course declare a SetTimeout for "x" seconds, and if that fires, then it would mean the user is still there (because we didn't get unloaded). The problem is that the user can take any time to decide whether to stay or not... I was first hoping that while the dialog was showing, SetTimeout calls would not fire, so I could set a timeout for a short time and it'd only fire if the user chose to stay. However, timeouts do fire while the dialog is shown, so that doesn't work. Another idea I tried is capturing mouseMoves on the window/document. While the dialog is shown, mouseMoves indeed don't fire, except for one weird exception that really applies to my case, so that won't work either. Can anyone think of other way to do this? Thanks! (In case you're curious, the reason capturing mouseMove doesn't work is that I have an IFrame in my page, containing a site from another domain. If at the time of unloading the page, the focus is within the IFrame, while the dialog shows, then I get the MouseMove event firing ONCE when the mouse moves from inside the IFrame to the outside (at least in Firefox). That's probably a bug, but still, it's very likely that'll happen in our case, so I can't use this method).

  • How to set document.domain for a dynamically generated IFRAME?

    - by Paras Chopra
    I am implementing CodeMirror (http://marijn.haverbeke.nl/codemirror/) on a page where document.domain needs to be declared (because of other IFRAMES on the page). CodeMirror generates a dynamic IFRAME to provide syntax highlighted code editing. The problem is that IE throws up 'Access Denied' (other browsers are fine) at the following piece of code mirror code: this.win = frame.contentWindow; ... var doc = this.win.document; <-- ERROR doc.open(); doc.write(html.join("")); doc.close(); It turns out IE doesn't inherit document.domain from parent IE. I can set document.domain in the IFRAME contents but IE throws up the error before I can even set the contents. Any ideas how to tackle this problem?

  • Change the content type of a pop up window.

    - by Oscar Reyes
    This question brought a new one: I have a html page and I need it to change the content type when the user press "save" button so the browser prompt to save the file to disk I've been doing this in the server side to offer "excel" versions of the page ( which is basically a html table ) <c:if test="${page.asExcelAction}"> <% response.setContentType("application/vnd.ms-excel"); %> What I'm trying to do now is to do the same, but in the client side with javacript but I can't manage to do it so. This is what I've got so far: <html> <head> <script> function saveAs(){ var sMarkup = document.getElementById('content').innerHTML; //var oNewDoc = document.open('application/vnd.ms-excel'); var oNewDoc = document.open('text/html'); oNewDoc.write( sMarkup ); oNewDoc.close(); } </script> </head> <body> <div id='content'> <table> <tr> <td>Stack</td> <td>Overflow</td> </tr> </table> </div> <input type="button" value="Save as" onClick="saveAs()"/> </body> </html>

  • Dynamically add new HTML elements on page load after getting JSON data from Web API

    - by Luis D Urraca
    I'm building an hybrid Android App using Phonegap/Apache Cordova. My app should get data from my web api. I'm using JSON to serve the data to the APP. So i got a the following code: function init() { document.addEventListener('deviceready', onDeviceReady, false); var url = "http://23.21.128.153:3000/regions.json";var jsonresults; $.getJSON(url,function(data){ jsonresults = data; $.each(jsonresults, function(i,v){ $('#main-content').append('<li>'+jsonresults[i].name+'</li>'); }); }); } and also on the body of the html i have a div called main-content. Everythings works fine in the Eclipse browser, but on the Android Emulator is not working. Not sure if there's another way to pull data from Web API using JSON and dinamically create HMTL elements after getting the data. https://gist.github.com/2956660
