    - by Joseph
    Hi all, Please help regarding the following issue. I have enabled the "Block popup" option in browser. We are doing a session validation using a background ajax call to check the session is active or not. If the session is not active for a desired interval a popup window will come for notification. Now comming to the problem . since the session notification popup is comming automatically without any client interaction, This popup is blocked by the browser. But if a client clicks anyother popup window in the form that popup window will not be blocked by the browser.

  • When page loads display 1st image text - hide all other text

    - by Jonah1289
    Hi I have created http://techavid.com/design/test3.html and when you load the page you see there are 3 images. The sun image is focused(in color), while the others are greyed out until clicked. That is how it should be for the images. Also when you load the page you see under each image it's own text(i.e. 1st: Sun, 2nd: Airplane, 3rd: Nano), but on page load I only want 1st:Sun to display and hide all other text until their respective image is clicked. Any idea how to do this? thanks :) J

  • customisable JSLint

    - by Don
    Hi, I'm looking for a tool that checks JS code, which can be integrated into a Maven build. I need a tool that will check for errors such as use of reserved words as identifiers trailing semi-colon, e.g. var obj = { a: 1, b, 2, } JSLint seems like a perfect candidate, but the problem is that it is too strict, because it also checks for various coding patterns which are (arguably) bad style, but do not actually generate errors in a browser. Examples of such issues include Disallow ++ and -- and Allow one var statement per function If possible, I would like the errors to fail the build, and I would like the other rules to only print warnings (or disable them completely). Obviously, I need the ability to specify which of the available rules I consider errors and which I consider warnings. Thanks, Don

  • Trigger the change event of a textbox in jQuery

    - by Danny Chen
    I have an asp:TextBox with asp:RegularExpressionValidator to validate if it's a number. Obviously an onchange event will be attached to this textbox while rendering. Also I add a change event at $(document).ready to make some calculation when the value is changed. <asp:TextBox id="myText" runat="server" /> <asp:regularexpressionvalidator id="myRev" ControlToValidate="myText" runat="server">*</asp:regularexpressionvalidator> $(document).ready(function(){ $('[id$=myText]').bind('change',function(){ //do something }).change(); //force the change event at the very beginning }); My function will be executed later than the .net generated js because of the register time. But the .net js throws an error. I traced in the js: function ValidatorOnChange(event) { ... } and found that all of event.fromElement,event.toElement,event.srcElement are null which causes the exception. Did I do something wrong? Any solutions? Thanks.

  • Question of using static_cast on "this" pointer in a derived object to base class

    - by Johnyy
    Hi, this is an example taken from Effective C++ 3ed, it says that if the static_cast is used this way, the base part of the object is copied, and the call is invoked from that part. I wanted to understand what is happening under the hood, will anyone help? class Window { // base class public: virtual void onResize() { } // base onResize impl }; class SpecialWindow: public Window { // derived class public: virtual void onResize() { // derived onResize impl; static_cast<Window>(*this).onResize(); // cast *this to Window, // then call its onResize; // this doesn't work! // do SpecialWindow- } // specific stuff };

  • Google map - How to escape charaters in the title of a marker in a google map?

    - by Anthony
    Say have this piece of code: var marker = new google.maps.Marker({ position: location, title: 'B&#250;fals', map: map }); This creates a marker as expected but if I hover the mouse over it I don’t see 'Búfals' as I would expect (instead I see the html code). This doesn't make any difference: var marker = new google.maps.Marker({ position: location, title: unescape('B&#250;fals'), map: map }); Any ideas? Thanks.

  • AJAX, same-origin Policy and working XML Requests

    - by Joern
    Hello guys, so, currently I develop Widgets for Smartphones and am going a bit more advanced into fields of data exchange between client and server applications. My problem is: For my current project I want my client file to request data from a PHP script with the help of AJAX XmlHttpRequest and the POST method: function xmlRequestNotes() { var parameter = 'p=1234'; xmlhttp = new XMLHttpRequest(); xmlhttp.open("POST", url, true); // Http Header xmlhttp.setRequestHeader("Content-Type", "application/x-www-form-urlencoded"); xmlhttp.setRequestHeader("Content-length", parameter.length); xmlhttp.setRequestHeader("Connection", "close"); xmlhttp.onreadystatechange=function() { if (xmlhttp.readyState==4 && xmlhttp.status==200) { json = JSON.parse(xmlhttp.responseText); // Doing Stuff with the Response } }; xmlhttp.send(parameter); } This works perfectly fine on my local server set up in XAMPP and the local Widget emulator. But if it gets onto the device (also with access to the target network) I receive the 101 Network Error. And as far as I have read, this is due to the "Same-Origin Policy" of XmlHttpRequests? My problem is to really understand that. Although the idea of this policy is clear to me, I'm a bit confused by the fact that another XmlHttpRequest for a Yahoo Weather XML Feed works fine. Now, could anyone be so helpful to enlighten me? Here is the request that returns a city name from Yahoo's weather feed: function getCityName() { xmlhttp = new XMLHttpRequest(); xmlhttp.open("GET", "http://weather.yahooapis.com/forecastrss?w=645458&u=c", true); xmlhttp.onreadystatechange = function() { if (xmlhttp.readyState==4 && xmlhttp.status==200) { xmlhttp.responseXML; var yweather = "http://xml.weather.yahoo.com/ns/rss/1.0"; alert(xmlhttp.responseXML.getElementsByTagNameNS(yweather, "location")[0].getAttribute("city")); } }; xmlhttp.send(null); } Obvious differences are the POST and GET methods for once, but seeing that the Same-Origin Policy takes effect no matter what method, I can't really make much sense of it. Why does the latter request work but not the first? I would really appreciate some help here. Greetings and a merry Christmas to you guys!

  • What is the best way to have a dynamic dropdownlist in PHP and POST selected value

    - by mouthpiec
    Hi, I am writing the following in PHP: i would like to have 2 dropdownlists, where the second one is populated from a mySQL dB according to the choice made on the first dropdown list. Then I would like to use the values of the selected values of the dropdownlist to call another PHP page in which I will generate a db query. Eg: List A: Car Manufactures (honda, nissan, etc) List B: Models (accord, civic, etc) Then I will have a submit button, to POST the values in another PHP file? (I have the basics of how to perform the above without having a dynamic list, but I tried this with AJAX, but I am having problems to pass the value of the second dropdownlist) Any tips of how I can perform the above?

  • How can I make a web-based "table" select like a spreadsheet? (rectangular area vs row-wrap selecti

    - by Dax
    I want to make a table that displays on a webpage, but one requirement is to make it easy to copy and paste into a spreadsheet. Normal HTML tables selection behavior is obviously different from how a spreadsheet like Excel selects -- when you select multiple rows it wraps around instead of selecting a rectangular area. Is there any way to make HTML table behave like a spreadsheet in this regard, or is the only way to resort to a Flash table or something similar?

  • Modify onclick function with jQuery

    - by Chris Barr
    I've got a button that has an onclick event in it, which was set on the back end from .NET. Beside it is a checkbox <button class="img_button" onclick="if(buttonLoader(this)){WebForm_DoPostBackWithOptions(new WebForm_PostBackOptions('uxBtnRelease', '', true, '', 'somepage.aspx?oupid=5&fp=true', false, true))} return false;" type="button">Release</button> <input type="checkbox" checked="checked" id="myCheckbox"> When the checkbox is clicked, needs to change the value of the query string in the URL inside the onclick function of the button. So far I have this, and the idea is right, but I keep getting errors when it's run: "Uncaught SyntaxError: Unexpected token ILLEGAL" var defaultReleaseOnClick=null; $("#myCheckbox").click(function(){ var $releaseBtn = $(".img_button"); if(defaultReleaseOnClick==null) defaultReleaseOnClick=$releaseBtn.attr("onclick"); var newOnClickString = defaultReleaseOnClick.toString().replace(/&fp=[a-z]+'/i,"&fp="+this.checked); $releaseBtn.removeAttr("onclick").click(eval(newOnClickString)); }); I know it seems kinda hacky to convert the function to a string, do a replacement, and then try to convert it back to a function, but I don't know any other way to do it. Any ideas? I've set up a demo here: http://jsbin.com/asiwu4/edit

  • Fatal error with Custom Magento Module on one server but not the other

    - by Jack
    Hi, I am creating my own custom module in Magento and during testing on a Litespeed server (PHP v5.2.14) I am getting a Fatal Error: Call to a member function batch() on a non-object in ../../../BatchController.php on line 25 that was not appearing during testing on another linux server and a wamp server (PHP v5.2.11). This one has stumped me. I am guessing it has something to do with the server configuration rather than the code itself. But i am just guessing. I was hoping someone here could tell me. The only real major difference I could see, aside from the php versions and environment, is that the server that the error is on is using the Suhosin Patch. But would that be something that could cause this? The line in question is Mage::getModel('mymodule/mymodel')->batch(); which is enclosed in an IF statement. batch() is a public function located in my model file. If you need more code let me know. Thanks!

  • Why Backbone.js isn't binding my event

    - by Saif Bechan
    I have a router like this, as main entry point: window.AppRouter = Backbone.Router.extend({ routes: { '': 'login' }, login: function(){ userLoginView = new UserLoginView(); } }); var appRouter = new AppRouter; Backbone.history.start({pushState: true}); I have a model/collection/view like this: window.User = Backbone.Model.extend({}); window.Users = Backbone.Collection.extend({ model: User }); window.UserLoginView = Backbone.View.extend({ events: { 'click #login-button': 'loginAction' }, initialize: function(){ _.bindAll(this, 'render', 'loginAction'); }, loginAction: function(){ var uid = $("#login-username").val(); var pwd = $("#login-password").val(); var user = new User({uid:uid, pwd:pwd}); } }); And body of my HTML looks like this: <form action="#" method="POST" id="login-form"> <p> <label for="login-username">username</label> <input type="text" id="login-username" autofocus /> </p> <p> <label for="login-password">password</label> <input type="password" id="login-password" /> </p> <a id="login-button" href="#">Inloggen</a> </form> Note: The HTML comes from Node.js using express.js, should I maybe wait for a document ready event somewhere? Edit: I have tried this, create the view when ready, did not solve the problem. $(function(){ userLoginView = new UserLoginView(); });
