  • one document.createElement, append it twice, only shows once

    - by Sirber
    I have a button I want to use in the beginning and the end of the page: var button_save = document.createElement('button'); $("#compteurs").append(button_save); [...] $("#compteurs").append(button_save); but it only appear at the end of the page. If I remove it from the bottom of the page, it appear at the begining of page. It's a kind of pointer. Is there a way to create the button only once and use it twice? Thanks!

  • plotting multiple google maps to page

    - by Roland
    I'm trying to append more than one Google Map to a page. But it seems like I'm having some trouble. This would be the template I'm using to ( with Handlebars.js ) to create the same block more than once, about 50 times : <script type="text/x-handlebars-template"> {{#each productListing}} <div class="product-listing-wrapper"> <div class="product-listing"> <div class="left-side-content"> <div class="thumb-wrapper" data-image-link="{{ThumbnailUrl}}"> <i class="thumb"> <img src="{{ThumbnailUrl}}" alt="Thumb"> <span class="zoom-image"></span> </i> </div> <div class="google-maps-wrapper"> <div class="google-coordonates-wrapper"> <div class="google-coordonates"> <p>{{LatLon.Lat}}</p> <p>{{LatLon.Lon}}</p> </div> </div> <div class="google-maps-button"> <a class="google-maps" href="#">Google Maps</a> </div> </div> </div> <div class="right-side-content"> <div class="map-canvas-wrapper"> <div id="map-canvas" class="map-canvas" data-latitude="{{LatLon.Lat}}" data-longitude="{{LatLon.Lon}}"></div> </div> <div class="content-wrapper"></div> </div> </div> </div> {{/each}} And I'm trying to append the map to the #map-canvas id. With the following block of code I'm doing the plotting : Cluster.prototype.initiate_map_assembling = function() { return $(this.map_canvas_wrapper_class).each(function(index, element) { var canvas = $(element).children(); var latitude = $(canvas).attr('data-latitude'); var longitude = $(canvas).attr('data-longitude'); var coordinates = new google.maps.LatLng(latitude, longitude); var options = { zoom: 9, center: coordinates, mapTypeId: google.maps.MapTypeId.ROADMAP }; var map = new google.maps.Map($(canvas), options); var marker = new google.maps.Marker({ position: coordinates, map: map }); }); }; This way I'm "looping" through all the parent classes of the id I'm trying to append the map to, but the map would only append to the first id. I tried to append it to all of the id's in other ways but with the same results. So what would you suggest me to do to make it work as I would expect it, append the map to each of the id's ?

  • Creating a pie chart for an app

    - by jhodgson4
    I'm developing an app which requires a pie chart to display a set number of modules. The modules need to be clickable, sending a value to the database for how many times the module has been clicked. The slices will change color etc depending on this database value. The slices will always be equal in size. All simple stuff. My question is what charting system would you use. I've been looking at google charts but I have no way of registering a value in a slice without changing its 'weight' in the chart. So ideally I would like to add data-stage="2" to each slice that I can access with a custom method. Also google charts seems quite heavy for what I need? Any advice would be greatly appreciated. Joe

  • Why doesn't the .click() not work in this instance?

    - by Deshiknaves
    Basically what this does is fadeIn pre-existing divs and then loads an image. When the image is loaded it then appends that into one of the pre-existing divs. Then it appends a new div with an id of xButton. Then later it $('#xButton').click() should hide the 3 divs. However it just doesn't work. If I change the click() to either #modalImage or #overlay, it works but just not for the #xButton. I would really like to figure out why its not working and how I should be doing this instead. Thanks. $(function(){ $('#container a').click(function(e){ e.preventDefault(); var id = $(this).attr('href'), img = new Image(); $('#overlay').fadeIn(function(){ $('#modalImage').fadeIn(); }); $(img).load(function(){ $(this).hide(); $('#modalImage').removeClass('loader').append(this); $(this).fadeIn(function(){ var ih = $(this).outerHeight(), iw = $(this).outerWidth(), newH = ($(window).height()/10)*7, newW = ($(window).width()/10)*7; if (ih >= iw && ih >= newH) { $(this).css('height',newH + 'px'); $(this).css('width', 'auto'); } else if (ih >= iw && newH > ih) { $(this).css('height', ih + 'px'); $(this).css('width', 'auto'); } else if (iw > ih && iw >= newW) { if ((newW / (iw / ih)) > newH) { $(this).css('width', 'auto'); $(this).css('height', newH + 'px'); } else { $(this).css('width', newW + 'px'); $(this).css('height', 'auto'); } } else { $(this).css('width', iw + 'px'); $(this).css('height', 'auto'); } var padW = ($(window).width() - $(this).outerWidth()) / 2, padH = ($(window).height() - $(this).outerHeight()) / 2; console.log (padH + ' ' + padW); $(this).css('top', padH); $(this).css('left', padW); if($('#overlay').is(":visible") == true) { ih = ih + 4; $('<div id="xButton">x</div>').appendTo('#modalImage'); if (padH >= 0) { $('#xButton').css('top', padH - 4).css('right', padW - 65); } else { $('#xButton').css('top', '20px').css('right', padW - 65); } } }); }).attr('src', id); }); $('#xButton').click(function(){ $(this).hide(); $('#overlay').fadeOut(function(){ $('#modalImage img').css('top', '-9999px').remove(); $('#xButton').remove(); $('#modalImage').addClass('loader'); }); }); });

  • Event to listen to attribute changes

    - by Luis
    I dont think this is possible but maybe someone knows a way to achieve this. I want to attach an event to an html element to listen to attribute change. So say for instance that I want something to happen when a visibility of a div changes. The reason is that I have no control over the javascript that is switching the visibility, hence the need for an event. Thanks

  • AJAX: Problems returning multiple variables

    - by fwaokda
    First off sorry if I'm missing something simple just started working with AJAX today. I have an issue where I'm trying to get information from my database, but different records have different amounts of values. For instance, each record has a "features" column. In the features column I store a string. (ex: Feature1~Feature2~Feature3~Feature4... ) When I'm building the object I take apart the string and store all the features into an array. Some objects can have 1 feature others can have up to whatever. So... how do I return this values back to my ajax function from my php page? Below is my ajax function that I was trying and I'll provide a link with my php file. [ next.php : http://pastebin.com/SY74jV7X ] $("a#next").click(function() { $.ajax({ type : 'POST', url : 'next.php', dataType : 'json', data : { nextID : $("a#next").attr("rel") }, success : function ( data ) { var lastID = $("a#next").attr("rel"); var originID = $("a#next").attr("rev"); if(lastID == 1) { lastID = originID; } else { lastID--; } $("img#spotlight").attr("src",data.spotlightimage); $("div#showcase h1").text(data.title); $("div#showcase h2").text(data.subtitle); $("div#showcase p").text(data.description); $("a#next").attr("rel", lastID); for(var i=0; i < data.size; i++) { $("ul#features").append("<li>").text(data.feature+i).append("</li>"); } /* for(var j=1; j < data.picsize; j++) { $("div.thumbnails ul").append("<li>").text(data.image+j).append("</li>"); } */ }, error : function ( XMLHttpRequest, textStatus, errorThrown) { $("div#showcase h1").text("An error has occured: " + errorThrown); } }); });

  • Want to set 'src' of script to my IP.

    - by Ozaki
    I have a script that links to the server I am hosting (IP can change) usually I would just use for links: var url ='http://' + window.location.hostname + 'end of url'; But in this case it isnt appearing to be so easy. I have tried: (1) $('#scriptid').attr('src', url); as well as: (2) var script = document.createElement( 'script' ); script.type = 'text/javascript'; script.src = url; $("#insert").append( script ); Now case (2) works loads the script runs the script. But when at the end of my script it hits the 'write data' it decides to replace the entire page with just the data. Any idea on how I can do this?

  • How do I avoid killing the native controls on a html5-video when i've started it programmaticly?

    - by Nils
    OK, so the deal is I've started making a little videoplayer, that works by clicking a div with an image, expanding the div and the image, and then exchanges the image with a html5-videotag. the code is as below. (It's very early on, so i know theres a lot that need improving, as in not using javascript to set styles and so on, but nevertheless, any insigts and tips are welcome, besides the answer to the main question) /*Begin Expander*/ var $videoplayer = $('<video width="640" height="360" preload="none" controls="" tabindex="0" style="position: relative;"><source type="video/mp4" src="/restalive/movies/big_buck_bunny.mp4"></source><source type="video/ogg" src="/restalive/movies/big_buck_bunny.ogv"></source></video>').appendTo('body'); $videoplayer.hide(); $(".ExpandVideo").each(function(i){ var $trigger = $(this); var $image = $trigger.find("img"); $image.css({ "width" : "100%" ,"height" : "auto" }) $trigger.css({ "display" : "block" ,"overflow" : "hidden" ,"width" : "200px" ,"float" : "left" }); $trigger.bind("click", function(e){ $trigger.animate({"width" : "640px"}, "fast", function(){ $image.replaceWith($videoplayer); $videoplayer.show(); $videoplayer.attr("id", "video" + i); var video = document.getElementById("video" + i); video.play(); }) }) }); However, the main problem is that when i've fired of the video like this (video.play()), the native controls stop working, i can no longer pause the video, even though the controls are there, and clickable, the video just starts playing immidiatley again when i trie to pause it. Which is a shame, because i want to use the native controls for simplicity.

  • Bootstrap-Switch options don't take effect

    - by Linda Keating
    I'm using Bootstrap-Switch and the documentation says that options can be passed as an object on initialization. enter link description here And here is a list of options: enter link description here So my code looks like this: var options = { onText: "Yes", onColor: 'primary', offColor: 'danger', offText: "No", animate: true, }; $("[name='radioGroup1']").bootstrapSwitch(options); And it all switch works fine, but none of the defaults are overwritten by the options. Anybody got any examples of how this might work? Thanks

  • color letters in a div

    - by Growler
    I've created a palindrome checker. I want to take it one step further and show the letters being compared as it is being checked. HTML: <p id="typing"></p> <input type="text" id="textBox" onkeyup="pal(this.value);" value="" /> <div id="response"></div> <hr> <div id="palindromeRun"></div> JS: To do this, I run the recursive check... Then if it is a palindrome, I run colorLetters(), which I'm trying to highlight in green each letter as it is being checked. Right now it is just rewriting palindromeRun's HTML with the first letter. I know this is because of the way I'm resetting its HTML. I don't know how to just grab the first and last letter, change only those letters' css, then increment i and j on the next setTimeout loop. var timeout2 = null; function pal (input) { var str = input.replace(/\s/g, ''); var str2 = str.replace(/\W/, ''); if (checkPal(str2, 0, str2.length-1)) { $("#textBox").css({"color" : "green"}); $("#response").html(input + " is a palindrome"); $("#palindromeRun").html(input); colorLetters(str2, 0, str2.length-1); } else { $("#textBox").css({"color" : "red"}); $("#response").html(input + " is not a palindrome"); } if (input.length <= 0) { $("#response").html(""); $("#textBox").css({"color" : "black"}); } } function checkPal (input, i, j) { if (input.length <= 1) { return false; } if (i === j || ((j-i) == 1 && input.charAt(i) === input.charAt(j))) { return true; } else { if (input.charAt(i).toLowerCase() === input.charAt(j).toLowerCase()) { return checkPal(input, ++i, --j); } else { return false; } } } function colorLetters(myinput, i, j) { if (timeout2 == null) { timeout2 = setTimeout(function () { console.log("called"); var firstLetter = $("#palindromeRun").html(myinput.charAt(i)) var secondLetter = $("#palindromeRun").html(myinput.charAt(j)) $(firstLetter).css({"color" : "red"}); $(secondLetter).css({"color" : "green"}); i++; j++; timeout2=null; }, 1000); } } Secondary: If possible, I'd just like to have it colors the letters as the user is typing... I realize this will require a setTimeout on each keyup, but also am not sure how to write this.

  • Display loading while webservice is running

    On the initial request to a page, I trigger a webservice and want to display a loading message. When the page has finished loading, I want to remove the waiting message from screen, but display it again when a change event in a checkbox triggers an Ajax call with another loading message. This code is not behaving to the given spec: $(document).ready( $(function() { $('#loadingDiv').hide(); $('#productsDropDown') .change(function() { var prodValue = $(this).val(); $('#proddate').load('getpdate.php', {prod: prodValue }); }); $('#loadingDiv') .ajaxStart(function() { $(this).show(); }) .ajaxStop(function() { $(this).hide(); }) ; }); ); what am I doing wrong?
