  • Phonegap (Cordova) iOS button click

    - by JNM
    I am trying to create a very simple phone gap application for iOS. I am using query mobile. the problem is, that i can't get javascript event to fire on button click. Code i have now: <!DOCTYPE html> <html> <head> <title>Title</title> <meta name="viewport" content="width=device-width, minimum-scale=1, maximum-scale=1"> <meta charset="utf-8"> <link rel="stylesheet" type="text/css" href="js/jquery.mobile-1.2.0.css" /> <script type="text/javascript" charset="utf-8" src="cordova-1.8.1.js"></script> <script type="text/javascript" charset="utf-8" src="js/jquery-1.8.2.min.js"></script> <script type="text/javascript" charset="utf-8" src="js/jquery.mobile-1.2.0.min.js"></script> <script type="text/javascript"> document.addEventListener("deviceready", onDeviceReady, false); function onDeviceReady() { } function showAlert() { navigator.notification.alert("Cordova is working"); } </script> </head> <body> <div data-role="page" id="options" data-add-back-btn="true" data-back-btn-text="Atgal"> <div data-role="header" data-position="fixed"> <h1>Title</h1> </div> <div data-role="content"> <h1>Alert</h1> <p><a href="#" onclick="showAlert(); return false;" data-role="button">Show alert</a></p> </div> </div> </body> </html> I tried multiple solutions to fix my problem, but none of them works. When have button with # in href, it doesn't event change the color on click. When i add url, it changes color. But it never call javascript function. Another problem is, that document.addEventListener("deviceready", onDeviceReady, false); works only in the index page. If i press button in initial page which redirects to another page, OnDeviceReady function is never called. Anybody has any ideas?

  • populate array fron list onclick javascript

    - by user3703591
    I 'm writing a code with JS and I don't know how to populate array when clicking on button. We have this code, which uses a list (ul), where the items (li) can be moved with mouse. How can do onclick to populate an array with 2 data, its first position and the last position? <!doctype html> <html lang="en"> <head> <script src="http://code.jquery.com/jquery-1.9.1.js"></script> <script src="http://code.jquery.com/ui/1.10.3/jquery-ui.js"></script> <script src="https://raw.github.com/furf/jquery-ui-touch-punch/master/jquery.ui.touch-punch.min.js"></script> <script> $(function() { $( ".documents" ).sortable(); $( ".documents" ).disableSelection(); }); </script> <meta charset="utf-8"> <title>toArray demo</title> <style> span { color: red; } </style> </head> <body> Reversed - <span></span> <ul id="opciones" class="documents"> <li>uno</li> <li>dos</li> <li>tres</li> </ul> <script> function disp( li ) { var a = []; for ( var i = 0; i < li.length; i++ ) { a.push( li[ i ].innerHTML ); } $( "span" ).text( a.join( " " ) ); } disp( $( "li" ).toArray() ); </script> <input type="button" value="actualizar_array" onclick="disp('#opciones')" /> </body> </html>

  • Find the exact height and width of the viewport in a cross-browser way (no Prototype/jQuery)

    - by lyoshenka
    I'm trying to find the exact height and width of a browser's viewport, but I suspect that either Mozilla or IE is giving me the wrong number. Here's my method for height: var viewportHeight = window.innerHeight || document.documentElement.clientHeight || document.body.clientHeight; I haven't started on width yet but I'm guessing it's going to be something similar. Is there a more correct way of getting this information? Ideally, I'd like the solution to work with Safari/Chrome/other browsers as well.

  • Local Variables take 7x longer to access than global variables?

    - by ItzWarty
    I was trying to benchmark the gain/loss of "caching" math.floor, in hopes that I could make calls faster. Here was the test: <html> <head> <script> window.onload = function() { var startTime = new Date().getTime(); var k = 0; for(var i = 0; i < 1000000; i++) k += Math.floor(9.99); var mathFloorTime = new Date().getTime() - startTime; startTime = new Date().getTime(); window.mfloor = Math.floor; k = 0; for(var i = 0; i < 1000000; i++) k += window.mfloor(9.99); var globalFloorTime = new Date().getTime() - startTime; startTime = new Date().getTime(); var mfloor = Math.floor; k = 0; for(var i = 0; i < 1000000; i++) k += mfloor(9.99); var localFloorTime = new Date().getTime() - startTime; document.getElementById("MathResult").innerHTML = mathFloorTime; document.getElementById("globalResult").innerHTML = globalFloorTime; document.getElementById("localResult").innerHTML = localFloorTime; }; </script> </head> <body> Math.floor: <span id="MathResult"></span>ms <br /> var mathfloor: <span id="globalResult"></span>ms <br /> window.mathfloor: <span id="localResult"></span>ms <br /> </body> </html> My results from the test: [Chromium 5.0.308.0]: Math.floor: 49ms var mathfloor: 271ms window.mathfloor: 40ms [IE 8.0.6001.18702] Math.floor: 703ms var mathfloor: 9890ms [LOL!] window.mathfloor: 375ms [Firefox [Minefield] 3.7a4pre] Math.floor: 42ms var mathfloor: 2257ms window.mathfloor: 60ms [Safari 4.0.4[531.21.10] ] Math.floor: 92ms var mathfloor: 289ms window.mathfloor: 90ms [Opera 10.10 build 1893] Math.floor: 500ms var mathfloor: 843ms window.mathfloor: 360ms [Konqueror 4.3.90 [KDE 4.3.90 [KDE 4.4 RC1]]] Math.floor: 453ms var mathfloor: 563ms window.mathfloor: 312ms The variance is random, of course, but for the most part In all cases [this shows time taken]: [takes longer] mathfloor Math.floor window.mathfloor [is faster] Why is this? In my projects i've been using var mfloor = Math.floor, and according to my not-so-amazing benchmarks, my efforts to "optimize" actually slowed down the script by ALOT... Is there any other way to make my code more "efficient"...? I'm at the stage where i basically need to optimize, so no, this isn't "premature optimization"...

  • Bug in Safari: options.length = 0; not working as expected in Safari 4

    - by Stefan
    This is not a real question, but rather an answer to save some others the hassle of tracking this nasty bug down. I wasted hours finding this out. When using options.length = 0; to reset all options of a select element in safari, you can get mixed results depending on wether you have the Web Inspector open or not. If the web inspector is open you use myElement.options.length = 0; and after that query the options.length(), you might get back 1 instead of 0 (expected) but only if the Web Inspector is open (which is often the case when debugging problem like this). Workaround: Close the Web Inspector or call myElement.options.length = 0; twice like so: myElement.options.length = 0; myElement.options.length = 0; Testcase: <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd"> <html> <head> <title>Testcase</title> <script type="text/javascript" language="javascript" charset="utf-8"> function test(el){ var el = document.getElementById("sel"); alert("Before calling options.length=" + el.options.length); el.options.length = 0; alert("After calling options.length=" + el.options.length); } </script> </head> <body onLoad="test();"> <p> Make note of the numbers displayed in the Alert Dialog, then open Web inspector, reload this page and compare the numbers. </p> <select id="sel" multiple> <option label="a----------" value="a"></option> <option label="b----------" value="b"></option> <option label="c----------" value="c"></option> </select> </body> </html>

  • Script that replaces strings doesn't work on some sites

    - by groovy354
    I've created a simple Chrome extension that seeks for certain strings using regex and replaces matches with predefined text. It works well on most websites, but somehow the script doesn't take effect on, for example, Lifehacker (like this page http://lifehacker.com/5939740/five-best-audio-editing-applications?popular=true ). The code is: $('p, h1, h2, h3, span, .content, .post-body').each(function(){ //do something with $(this) }); Any ideas why is Lifehacker's site resistant to my script?

  • Jetty servlet respons to Ajax always empty

    - by chris
    Hi I try to run a java server on Jetty which should respond to an ajax call. Unfortunately the response seems to be empty when I call it with ajax. When I call http://localhost:8081/?id=something I get an answer. The Java Server: public class Answer extends AbstractHandler { public void handle(String target, Request baseRequest, HttpServletRequest request, HttpServletResponse response) throws IOException, ServletException { String id = request.getParameter("id"); response.setContentType("text/xml"); response.setHeader("Cache-Control", "no-cache"); response.setContentLength(19+id.length()); response.setStatus(HttpServletResponse.SC_OK); response.getWriter().write("<message>"+id+"</message>"); //response.setContentType("text/html;charset=utf-8"); response.flushBuffer(); baseRequest.setHandled(true); } public static void main(String[] args) throws Exception { Server server = new Server(8081); server.setHandler(new Answer()); server.start(); server.join(); } } The js and html: <html> <head> <script> var req; function validate() { var idField = document.getElementById("userid"); var url = "validate?id=" + encodeURIComponent(idField.value); if (typeof XMLHttpRequest != "undefined") { req = new XMLHttpRequest(); } else if (window.ActiveXObject) { req = new ActiveXObject("Microsoft.XMLHTTP"); } req.open("GET", "http://localhost:8081?id=fd", true); req.onreadystatechange = callback; req.send(null); } function callback() { if (req.readyState == 4) { if (req.status == 200) { var message = req.responseXML.getElementsByTagName("message")[0]; document.getElementById("userid").innerHTML = "message.childNodes[0].nodeValue"; } } } </script> </head> <body onload="validate('foobar')"> <div id="userid">hannak</div> </body> </html> I'm actually don't know what I'm doing wrong here. Maybe someone has a good idea. greetings chris

  • JavaScript Coding for Finding Shipping Total

    - by user2913279
    I am having a very hard time with this code. I have been working on it for days and cannot seem to figure it out. Please help!! Here are the specific I need for the code: Many companies normally charge a shipping and handling charge for purchases. Create a Web page that allows a user to enter a purchase price into a text box and includes a JavaScript function that calculates shipping and handling. Add functionality to the script that adds a minimum shipping and handling charge of $1.50 for any purchase that is less than or equal to $25.00. For any orders over $25.00, add 10% to the total purchase price for shipping and handling, but do not include the $1.50 minimum shipping and handling charge. The formula for calculating a percentage is price * percent / 100. For example, the formula for calculating 10% of a $50.00 purchase price is 50 * 10 / 100, which results in a shipping and handling charge of $5.00. After you determine the total cost of the order (purchase plus shipping and handling), display it in an alert dialog box. Here is the code I have: <!DOCTYPE> <head> <title>Calculate Shipping</title> <script type="text/javascript"> function parseInt() { var salesPrice = document.salesForm.Price.value; var minCharge = salesPrice + 1.50; var shipping = salesPrice * 10/100; if (salesPrice <= 25) window.alert('Your sales total including shipping is $' + minCharge); else window.alert('Your sales total including shipping is $' + salesPrice + shipping); } </script> </head> <body> <form name="salesForm"> <div > <p>Enter Your Purchase Price</p> <input type="text" name="Price" /><br /><br /> <input type="button" name="Calculate" value="Calculate Shipping" onclick="parseInt ()" /> </div> </form> </body> </html> Everything works except for the math in the alert box. It will show an incorrect total...

    I have VS 2010 and Word 2010. In Word 2010 there is sometimes a message/warning bar that pops up under the ribbon but above the body of the document that allows the user to do an action. It looks something like this... Can I programmatically though VSTO or Interop create a custom bar that allows the user to click a button and then it executes some code. If not, is there an alternative popup or dialog box that will do something like this? Thanks, A

    I am trying to get a feel for adding content to a page with XMLHTTPRequest. I would like to add the results to existing page content say in a second column, but I am not having any luck. I would appreciate a shove in the right direction.

  • Mobile Safari text selection after input field focus

    - by Andy
    I have some legacy html that needs to work on old and new browsers (down to IE7) as well as the iPad. The iPad is the biggest issues because of how text selection is handled. On a page there is a textarea as well as some text instructions. The instructions are in a <div> and the user needs to be able to select the instructions. The problem is that once focus is placed in the textarea, the user cannot subsequently select the text instructions in the <div>. This is because the text cannot receive focus. According to the Safari Web Content Guide: Handling Events (especially, "Making Elements Clickable"), you can add a onclick event handler to the div you want to receive focus. This solution works (although it is not ideal) in iOS 6x but it does not work in iOS 5x. Does anyone have a suggestion that minimizes changes to our existing code and produces consistant user interaction. Here is sample code that shows the problem. <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"> <html> <head> <meta http-equiv="content-type" content="text/html; charset=UTF-8"> <script src="http://code.jquery.com/jquery-1.8.2.js"></script> <!-- Resources: Safari Web Content Guide: Handling Events (especially, "Making Elements Clickable") http://developer.apple.com/library/safari/#documentation/appleapplications/reference/safariwebcontent/HandlingEvents/HandlingEvents.html#//apple_ref/doc/uid/TP40006511-SW1 --> </head> <body> <div style="width:550"> <div onclick='function() { void(0); }'> <p>On the iPad, I want to be able to select this text after the textarea has had focus.</p> </div> <textarea rows="20" cols="80">After focus is in the textarea, can you select the text above?</textarea> </div> </body> </html>

  • How to set an onClick attribute that would load dynamic content?

    - by konzepz
    This code is suppose to add an onClick event to each of the a elements, so that clicking on the element would load the content of the page dynamically into a DIV. Now, I got this far - It will add the onClick event, but how can I load the dynamic content? $(document.body).ready(function () { $("li.cat-item a").each(function (i) { this.setAttribute('onclick','alert("[load content dynamically into #preview]")'); }); }); Thank you.

  • jQuery Accordion /Tabs - Call different function upon load of content

    - by Scott
    I have the following markup: <body> <div id="tabs" style="float: left"> <ul> <li><a href="ajax/question_0.html" title="Question 1"><span>Question 1</span></a></li> <li><a href="ajax/question_1.html" title="Question 2"><span>Question 2</span></a></li> <li><a href="ajax/question_2.html" title="Question 3"><span>Question 3</span></a></li> <li><a href="ajax/question_3.html" title="Question 4"><span>Question 4</span></a></li> <li><a href="ajax/question_4.html" title="Question 5"><span>Question 5</span></a></li> <li><a href="ajax/question_5.html" title="Question 6"><span>Question 6</span></a></li> </ul> <div id="dynamicContent"> </div> </div> <div class="demo-description"> <p>Click tabs to see answers to Questions</p> </div> </body> I would like to utilize an accordion or the tabs plugin from the UI. Upon completion of the load event, I'd like to call a JavaScript function, but a different function for each tab -- almost like calling onDocumentReady for a page. I have the following JavaScript: $(function() { $('#tabs').tabs().bind('tabsselect', function(event, ui) { console.log("Loading: ajax/question_" + ui.index + ".html"); return true; //Ensure that the tab gets selected }); ); That's properly loading the Ajax file and all, but whenever I attempt to do something such as evaluating a statement in the JS, it seems to be ignored. Is there any way I can do this, so that once the file is loaded my function is called -- needs to be a different function for each tab.
