  • How to calculate the latlng of a point a certain distance away from another?

    - by Rene Saarsoo
    To draw a circle on map I have a center GLatLng (A) and a radius (r) in meters. Here's a diagram: ----------- --/ \-- -/ \- / \ / \ / r \ | *-------------* \ A / B \ / \ / -\ /- --\ /-- ----------- How to calculate the GLatLng at position B? Assuming that r is parallel to the equator. Getting the radius when A and B is given is trivial using the GLatLng.distanceFrom() method - but doing it the other way around not so. Seems that I need to do some heavier math.

  • splice() not working on correctly

    - by adardesign
    I am setting a cookie for each navigation container that is clicked on. It sets an array that is joined and set the cookie value. if its clicked again then its removed from the array. It somehow buggy. It only splices after clicking on other elements. and then it behaves weird. It might be that splice is not the correct method Thanks much. var navLinkToOpen; var setNavCookie = function(value){ var isSet = false; var checkCookies = checkNavCookie() setCookieHelper = checkCookies? checkCookies.split(","): []; for(i in setCookieHelper){ if(value == setCookieHelper[i]){ setCookieHelper.splice(value,1); isSet = true; } } if(!isSet){setCookieHelper.push(value)} setCookieHelper.join(",") document.cookie = "navLinkToOpen"+"="+setCookieHelper; } var checkNavCookie = function(){ var allCookies = document.cookie.split( ';' ); for (i = 0; i < allCookies.length; i++ ){ temp = allCookies[i].split("=") if(temp[0].match("navLinkToOpen")){ var getValue = temp[1] } } return getValue || false } $(document).ready(function() { $("#LeftNav li").has("b").addClass("navHeader").not(":first").siblings("li").hide() $(".navHeader").click(function(){ $(this).toggleClass("collapsed").nextUntil("li:has('b')").slideToggle(300); setNavCookie($('.navHeader').index($(this))) return false }) var testCookies = checkNavCookie(); if(testCookies){ finalArrayValue = testCookies.split(",") for(i in finalArrayValue){ $(".navHeader").eq(finalArrayValue[i]).toggleClass("collapsed").nextUntil(".navHeader").slideToggle (0); } } });

  • Patterns for avoiding jQuery silent fails

    - by Matias
    Is there any good practice to avoid your jQuery code silently fail? For example: $('.this #is:my(complexSelector)').doSomething(); I know that every time this line get executed, the selector is intended to match at least one element, or certain amount of elements. Is there any standard or good way to validate that? I thought about something like this: var $matchedElements = $('.this #is:my(complexSelector)'); if ($matchedElements.length < 0) throw 'No matched elements'; $matchedElements.doSomething(); Also I think unit testing would be a valid option instead of messing the code. My question may be silly, but I wonder whether there is a better option than the things that I'm currently doing or not. Also, maybe I'm in the wrong way checking if any element match my selector. However, as the page continues growing, the selectors could stop matching some elements and pieces of functionality could stop working inadvertently.

  • Client side page call/scrape?

    - by Silvre
    Here is the problem: I have a web application - a frequently changing notification system - that runs on a series of local computers. The application refreshes every couple of seconds to display the new information. The computers only display info, and do not have keyboards or ANY input device. The issue is that if the connection to the server is lost (say updates are installed and a server must be rebooted), a page not found error is displayed). We must then either reboot all computers that are running this app, OR add a keyboard and refresh the browser, OR try to access each computer remotely and refresh the browser. None of these are good options and result in a lot of frustration. I cannot change the actual application OR server environment. So what I need is some way to test the call to the application, and if an error is returned or it times out, continue trying every minute or so until the connection is reestablished. My idea is to create a client-side page scraper, that makes a JS request to the application (which displays basic HTML), and can run locally on the machine, no server required. If the scrape returns the correct content, it displays it. If not it continues to request the page until the actual page content is returned. Is this possible? What is the best way to do it?

  • Why does document.QuerySelectorAll return a StaticNodeList rather than a real Array?

    - by Kev
    It bugs me that I can't just do document.QuerySelectorAll(...).map(...) even in Firefox 3.6, and I still can't find an answer, so I thought I'd cross-post on SO the question from this blog: http://blowery.org/2008/08/29/yay-for-queryselectorall-boo-for-staticnodelist/ Does anyone know of a technical reason why you don't get an Array? Or why an SNL doesn't inherit from an Array in such a way that you could use map, concat, etc? (BTW if it's just one function you want, you can do something like NodeList.prototype.map = Array.prototype.map;...but again, why is this functionality (intentionally?) blocked in the first place?)

  • Toggled() text input field not working in IE6 in Jquery 1.3.2

    - by Michal
    In IE6 after showing() or toggling() an initially hidden text input field it is impossible to enter any text in the box. It is also impossible to focus() on the element. I am using jquery 1.3.2 Here is the code...

  • How to animate button text? (loading type of animation) - jquery?

    - by AL
    I got something that I want to do and want to see what you guys think and how can it be implemented. I got a form in a page and the form will submit to itself to perform some process (run functions) in a class. Upon clicking the submit button, I want to animate the button text to “SUBMIT .” -> “SUBMIT ..” -> “SUBMIT …” -> “SUBMIT ….” -> “SUBMIT ….” and then back again. Sort of “animate” the button text. Once the whole process is done, the button text will goes back to be “SUBMIT” text again. Please note that I am not looking for image button solution, meaning that I do not want to implement gif animated button image. Anyone done this before or know how this can be done? I have google but seems nothing of this kind to be found. Thanks! AL

  • Ajax "deselects" hyperlink under the mouse cursor.

    - by thealliedhacker
    I have a page that performs an Ajax request that replaces a div every second. This div also has hyperlinks in it. If the user tries to click one of the hyperlinks, it will work, but if they move the cursor over the link, wait for a second without moving the cursor, the hyperlink no longer has the "hover" pseudostyle and if they click at the wrong time, the link doesn't work. Is there a way to update the div without causing this, or to restore the "mouse over" state of the link?

  • Why isn't IE displaying this alert()?

    - by George Edison
    I have the following piece of code: // setup the AJAX request var pageRequest = false; if(window.XMLHttpRequest) pageRequest = new XMLHttpRequest(); else if(window.ActiveXObject) pageRequest = new ActiveXObject("Microsoft.XMLHTTP"); // callback pageRequest.onreadystatechange = function() { alert('pageRequest.readyState: ' + pageRequest.readyState + '\npageRequest.status: ' + pageRequest.status); } pageRequest.open('POST','ajax.php',true); // q_str contains something like 'data=value...' pageRequest.setRequestHeader("Content-type", "application/x-www-form-urlencoded"); pageRequest.setRequestHeader("Content-length", q_str.length); pageRequest.setRequestHeader("Connection", "close"); pageRequest.send(q_str); This works fine in Chrome, but IE chokes on it, spitting out an "Unspecified error." and it points to the line with the alert() in it. Why can't it display the alert?

  • Advantages of createElement over innerHTML?

    - by oninea
    In practice, what are the advantages of using createElement over innerHTML? I am asking because I'm convinced that using innerHTML is more efficient in terms of performance and code readability/maintainability but my teammates have settled on using createElement as the coding approach. I just wanna understand how createElement can be more efficient.

  • Using input type="submit" to change content

    - by Conti
    Okay, I'm pretty sure I'm missing something very obvious here, but I just couldn't find a proper solution so far. What I'm trying to do is simple: Have a user write something into a form, have him submit the form, and write that input into a textarea on the same page. This is my code: <html><head></head> <body> <form name='registration'> <label for="input">Input:</label> <input type="text" id="input"/> <input type="submit" id="submit" value="Submit" onclick="execute()"/> </form> <div id="results"> <span>Result</span> <span><textarea cols="30" rows="5" id="resulttext" readonly="readonly"></textarea> </span> </div> <script> function execute() { var result = document.getElementById("input").value document.getElementById("resulttext").value=result; } </script> </body> </html> Now what happens if I enter something into the form is that the textarea briefly shows my input before reverting back to showing nothing. My guess is that the textarea field is only changed for the duration of the execute() function. When I change input type="submit" to a <button> everything works as intended, but I'm pretty sure I'm not supposed to do that.

  • Can't append to second container

    - by George Katsanos
    I have the following script: (function($) { $.fn.easyPaginate = function(options){ var defaults = { step: 4, delay: 100, numeric: true, nextprev: true, controls: 'pagination', current: 'current' }; var options = $.extend(defaults, options); var step = options.step; var lower, upper; var children = $(this).children(); var count = children.length; var obj, next, prev; var page = 1; var timeout; var clicked = false; function show(){ clearTimeout(timeout); lower = ((page-1) * step); upper = lower+step; $(children).each(function(i){ var child = $(this); child.hide(); if(i>=lower && i<upper){ setTimeout(function(){ child.fadeIn('fast') }, ( i-( Math.floor(i/step) * step) )*options.delay ); } if(options.nextprev){ if(upper >= count) { next.addClass('stop'); } else { next.removeClass('stop'); }; if(lower >= 1) { prev.removeClass('stop'); } else { prev.addClass('stop'); }; }; }); $('li','#'+ options.controls).removeClass(options.current); $('li[data-index="'+page+'"]','#'+ options.controls).addClass(options.current); if(options.auto){ if(options.clickstop && clicked){}else{ timeout = setTimeout(auto,options.pause); }; }; }; function auto(){ if(upper <= count){ page++; show(); } else { page--; show(); } }; this.each(function(){ obj = this; if(count>step){ var pages = Math.floor(count/step); if((count/step) > pages) pages++; var ol = $('<ol id="'+ options.controls +'" class="pagin"></ol>').insertAfter(obj); if(options.nextprev){ prev = $('<li class="prev">prev</li>') .appendTo(ol) .bind('click', function() { //check to see if there are any more pages in the negative direction if (page > 1) { clicked = true; page--; show(); } }); } if(options.numeric){ for(var i=1;i<=pages;i++){ $('<li data-index="'+ i +'">'+ i +'</li>') .appendTo(ol) .click(function(){ clicked = true; page = $(this).attr('data-index'); show(); }); }; }; if(options.nextprev){ next = $('<li class="next">next</li>') .appendTo(ol) .bind('click', function() { //check to see if there are any pages in the positive direction if (page < (count / 4)) { clicked = true; page++; show(); } }); } show(); }; }); }; })(jQuery); jQuery(function($){ $('ul.news').easyPaginate({step:4}); }); which is a carousel-like plugin that produces this html structure for the navigation: <ol id="pagination" class="pagin"><li class="prev">prev</li><li data-index="1" class="">1</li><li data-index="2" class="">2</li><li data-index="3" class="current">3</li><li class="next stop">next</li></ol> And all I want is to enclose this list in a div. Seems simple, but appendTo doesn't want to cooperate with me, or I'm doing something wrong (I'd appreciate if you would help me understand what that is..) So I'm modifying as such: var ol = $('<ol id="'+ options.controls +'" class="pagin"></ol>'); var tiv = $('<div id="lala"></div>'); ol.appendTo('#lala'); tiv.insertAfter(obj); I know how to chain, but I'm in "debugging" mode trying to understand why I don't get the result I imagine I would get: <div id="lala> <ol id="pagination><li>...... </li></ol> </div> I tried putting some console.log's to see the status of my variables but couldn't find something useful.. I guess there's something with DOM insertion I don't get.

  • getElementsByTagName() equivalent for textNodes

    - by levik
    Is there any way to get the collection of all textNode objects within a document? getElementsByTagName() works great for Elements, but textNodes are not Elements. Update: I realize this can be accomplished by walking the DOM - as many below suggest. I know how to write a DOM-walker function that looks at every node in the document. I was hoping there was some browser-native way to do it. After all it's a little strange that I can get all the <input>s with a single built-in call, but not all textNodes.

  • Why aren't my JQuery .ajax requests being made in parallel?

    - by Ryan Olson
    I am trying to make two ajax requests in parallel using jQuery like this: var sources = ["source1", "source2"]; $(sources).each(function() { var source = this; $.ajax({ async: true, type: "POST", data: {post: "data", in: "here"}, url: "/my/url/" + source, success: function(data) { process_result(data); } }); }); I got the basic structure from this question, but my requests still aren't being made in parallel. "source1" takes a while to complete, and I can see on the server that the second request isn't made until the first is completed. As far as I can tell, I don't have any other active requests, so I don't think it's a problem with the maximum number of parallel requests for the browser. Am I missing something else here?

  • Fluid width Son of Suckerfish dropdown menus

    - by derekerdmann
    For CSS dropdown menus, I usually stick with the Son of Suckerfish dropdowns. The technique works extremely well, but there's one small thing that's always bothered me: the width of the dropdown links is always fixed. Are there any ways to automatically resize the width of the items in a Suckerfish dropdown menu? If not, are there any other CSS-based dropdown menu strategies that can accomplish this?

  • Implementing a server side push for a small number of clients

    - by Helper Method
    For an web application I am working on I have the following requirements: Clients need to be able to log in via a web brower. After logging in, they will be able to change configurations (normal request/response) will be able to receive alarms sent by the server (a server side push) Now, the question is how to implement the alarms. I first thought of using some long polling approach (Comet), but as the amount of clients will definitely belimited to 5-10, I'm now thinking to go with a simpler approach. What are the options I have? Would it be okay to just let the clients poll the server? Important aspects are: Alarms should be delivered in (nearly) real-time. Alarms must not get lost (a lost alarm could cause harm to real people).

  • Unbind Events with JQuery: Does it work with events setup in HTML?

    - by Abs
    Hello all, I have a few onclick and on mouseover events in my html generated by PHP, something like this: <div onmouseover="fave('heart_<?php echo $row['id']; ?>';" class="heart"><a href=""></a></div> I wish to make use of unbind on the mouseover but it hasn't worked when I tried this: $('#'+ id).unbind('mouseover'); So I am guessing unbind will only work with events created by JQuery? Is there something else I can try? Btw, I can't move my events to a separate js file as each id is unique and. Thanks all

  • In an array of buttons, how can you tell which button was clicked?

    - by Michael Seltenreich
    If I have an array of buttons, how can I tell which button was clicked? example below var i=0 CreateButton = new function () { savebutton[i]=NewButton() i++ } every time a user runs the function a new button is generated. the first button is savebutton[0] the second is savebutton[1] and so on potentially infinity times. when later the user presses the button I want the screen to alert it's index number (or 'i'). is there any way to make this work in arrays?

  • Modifying DOM of a webpage

    - by Prashant Singh
    The structure of a webpage is like this :- <div id='abc'> <div class='a'>Some contents here </div> <div class='b'>Some other contents< </div> </div> My aim is to add this after the class a in above structure. <div class='a'>Some other contents here </div> So that final structure looks like this :- <div id='abc'> <div class='a'>Some contents here </div> <div class='a'>Some other contents here </div> <div class='b'>Some other contents< </div> </div> Can there be a better way to do this using DOM properties. I was thinking of naive way of parsing the content and updating. Please comment if I am unclear in asking my doubt !
