  • Javascript Canvas Element - Array Of Images

    - by Ben Shelock
    I'm just learning JS, trying to do things without jQuery, and I want to make something similar to this however I want to use an array of images instead of just the one. My image array is formed like this var image_array = new Array() image_array[0] = "image1.jpg" image_array[1] = "image2.jpg" And the canvas element is written like this. (Pretty much entirely taken from the Mozilla site) function draw() { var ctx = document.getElementById('canvas').getContext('2d'); var img = new Image(); img.src = 'sample.png'; img.onload = function(){ for (i=0;i<5;i++){ for (j=0;j<9;j++){ ctx.drawImage(img,j*126,i*126,126,126); } } } } It uses the image "sample.png" in that code but I want to change it to display an image from the array. Displaying a different one each time it loops. Apoligies if I've not explained this well.

  • Passing GLatLng from array to Google

    - by E. Rose
    Hello All, To preface this, I am a complete programming amateur so this may be quite easily solved. As is though, it is frustrating me to no end. Basically, I have a database of Venue Names with GLat and GLng (other stuff too) that I am pulling down to my website based on a geolocated search. The javascript that I have pulls in a formatted subset of the database, dumps the glat and glng into an array and is supposed to take those points and plot out several markers each with an info window containing the details behind each marker. For some reason, the marker geodata is not being populated and/or is not being passed. The array is declared using [] and will not work when normally declared using (). It only brings up a map with the first value in the array and goes blank if i try to manually input later entries. There is a large block of commented out code relating to directions generation. That code worked for some reason. If anyone can tell me what I am doing wrong in rewriting it to map the markers and not give directions, please tell me. Any help would be much appreciated. var letters = ['A', 'B', 'C', 'D', 'E', 'F', 'G', 'H', 'I', 'J', 'K', 'L', 'M', 'N', 'O', 'P', 'Q', 'R', 'S', 'T', 'U', 'V', 'W', 'X', 'Y', 'Z']; google.load("maps", "2", {"other_params":"sensor=true"}); var map function initialize(){ window.map = new google.maps.Map2(document.getElementById("map")); map.addControl(new GLargeMapControl()); } google.setOnLoadCallback(initialize); function getVenueResults(_zip, _num, _remove){ var rFlag = ''; if(_remove != null){ rFlag = "&removeId=" + _remove; } var url = 'ajax/getVenues.php?zip=' + _zip + "&num=" + _num + rFlag; new Ajax.Updater('resultsContainer', url, { onComplete: processResults }); } function processResults(){ window.map.clearOverlays(); var waypoints = []; var resultsList = $$('.resultWrapper'); var stepList = $$('.resultDirections'); for(i=0; i for(i=0; i<resultsList.length; i++){ var resultsElem = resultsList[i]; resultsElem.removeClassName('firstResult'); resultsElem.removeClassName('lastResult'); if(i == 0){ resultsElem.addClassName('firstResult'); } if(i == resultsList.length - 1){ resultsElem.addClassName('lastResult'); } var insertContent = '<div class="resultDirections" id="resultDirections' + i + '"></div>'; Element.insert(resultsElem, { bottom : insertContent }) var num = resultsElem.getElementsByClassName('numHolder'); num[0].innerHTML = '<b>' + letters[i] + ".</b> "; var geolat = resultsElem.getElementsByClassName('geolat')[0].value; var geolong = resultsElem.getElementsByClassName('geolong')[0].value; var point = new GLatLng(geolat, geolong); waypoints[i] = point; } if(waypoints.length == 1){ map.setCenter(waypoints[0], 16); map.addOverlay(new GMarker(waypoints[0])); resultsElem.getElementsByClassName('numHolder')[0].innerHTML = ''; }else{ map.setCenter(waypoints[0], 16); for(j=0; j< waypoints.length; j++) { var vLoc = waypoints[j]; var vInfo = resultsElem.getElementByClassName('resultBox[j]]').innerHTML; //unfinished function to mine name out of div and make it the marker title //x = resultsElem.getElementsByTagName("b"); // for (i=0;i<x.length;i++) // //marker.value = resultsElem.getElementBy('numHolder').innerHTML var marker = createMarker(vLoc, vInfo); map.addOverlay(marker); } } function createMarker(vLoc, vInfo) { var marker = (new GMarker(vLoc)); var cont = vInfo; GEvent.addListener(marker, 'click', function() { marker.openInfoWindowHtml(cont); }); return marker; } //var directions = new GDirections(window.map, document.getElementById('directionsPanel')); //directions.loadFromWaypoints(waypoints, { travelMode: G_TRAVEL_MODE_WALKING }); //GEvent.addListener(directions, "load" , function() { // var numRoutes = directions.getNumRoutes(); // for(j=0; j< numRoutes; j++){ // var thisRoute = directions.getRoute(j); // var routeText = ''; // for(k=0; k < thisRoute.getNumSteps(); k++){ // var thisStep = thisRoute.getStep(k); // if(k != 0){ routeText += " &nbsp;||&nbsp; "; } // routeText += thisStep.getDescriptionHtml(); // } // $('resultDirections' + j).innerHTML = routeText; // } // $('resultDirections' + numRoutes).hide(); //}); } function moveUp(_obj){ var parentObj = $(_obj).up().up(); var prevSib = parentObj.previous(); prevSib.insert({before: parentObj}); processResults(); } function moveDown(_obj){ var parentObj = $(_obj).up().up(); var nextSib = parentObj.next(); nextSib.insert({after: parentObj}); processResults(); }

  • textfield value empty when i fill it with javascript

    - by Turi
    i am using modalpopup to enter some value in a textfield. after the value is selected in the modalpopup view, the modalpopup is closed and the value has taken the propriate value. Even if the value is displyed in the textfield, the textfield1.text returns me string empty. when i see the source code (html), i see that even that the textfield is displaying something it hasn't really this value in it, because the appropriate html input field hasn't value yet. thats the code i use to fill this textfield. function CloseRequestModal(s) { document.getElementById('<%=txtRequest.ClientID%>').value = s; var mpu = $find('<%=ModalPopupExtender3.ClientID%>'); mpu.hide(); } Please Help, Thanks in advance.

  • Wrong image dimensions when it's dynamically loaded on a page the 1st time

    - by Nikita Barsukov
    I have the following piece of Javascript code on my web-page var central_image = document.createElement("img") central_image.setAttribute("src", imgs[curr_image_no - 1]); central_image.setAttribute("name", "jpeg"); document.getElementById("photo").appendChild(central_image); central_image.onload = getDimensions(); //function that alerts image dimensions Now, when the central_image is loaded for the 1st time in Firefox, its height always equals to 0. In IE its dimensions are 28 x 30 pixels. When I reload image, its dimensions are OK in both browsers. I guess the problem is that function getDimensions() starts before image was loaded completely. How to change that?

  • How to capture a click on a link on a temporary layer that is hidden when the focus changes

    - by hstoerr
    We have a layer that appears when a certain text input has the focus and that should dissappear when the input loses the focus. I tried to do it like this: <input type="text" onblur="document.getElementById('hideme').style.display='none'" /> <div id="hideme">Textextext <a href="http://disney.com/">disney</a> text</div> My problem is: when the user clicks on the link link, the browser does not follow this link. It seems the layer disappears before the browser checks where the click goes. What can I do here? One idea would be to watch whether the mouse enters the hideme div and not to close it when the mouse cursor is in there, but this seems way to complicated. Do you have a better idea? By the way: you can try it out very easy by pasting this into the Tryit Editor of w3schools. :-)

  • Access ASP.NET control using javascript

    - by user3036965
    I have a basic javascript function like this which works as I am able to dynamically change the textbox in a javascript method at runtime. function MyTst(pVal2) { var x = document.getElementById('<%=myImage.ClientID%>'); x.src = "/images/write.gif"; } In the above code I need to be generic. So replace '<%=myImage.ClientID%' with the input param to my method which in this instance is called pVal2 and contains the asp.net server control image id. Can anyone advise on an approach to do this. I've tried lots of things and just cant seem to get it working. Thanks for any advice.

  • How to get a Javascript routine to NOT act if it's in a text box?

    - by talkingnews
    I've got a simple page, and in that page runs a simple jquery keypress routine to catch clicks of the numbers 1 to 9 (has to be that to pass RNIB accessibility test). And in that page is a form, which can have numbers entered as part of a postcode. http://find.talking-newspapers.co.uk/result.php?addressInput=kingston Scroll to the bottom, try typing 8 or 9 for example. The text is entered, but it also acts on the keypress. Expected, but not good. I'm aware of various things like document.getElementById, but I can't figure out how to put these together to ensure that while the cursor is in the text input box, it doesn't act out the keypress catcher.

  • How can I use Perl to grab text from a web page that is dynamically generated with JavaScript?

    - by bstullkid
    There is a website I am trying to pull information from in Perl, however the section of the page I need is being generated using javascript so all you see in the source is: <div id="results"></div> I need to somehow pull out the contents of that div and save it to a file using Perl/proxies/whatever. e.g. the information I want to save would be document.getElementById('results').innerHTML; I am not sure if this is possible or if anyone had any ideas or a way to do this. I was using a lynx source dump for other pages but since I cant straight forward screen scrape this page I came here to ask about it! If anyone is interested, the page is http://downloadcenter.trendmicro.com/index.php?clk=left_nav&clkval=pattern_file&regs=NABU and the info I am trying to get is the row about the ConsumerOPR

  • Multiple ASP.Net Controls On One Page

    - by Duracell
    We have created a User Control for ASP.Net. At any one time, a user's profile page could contain between one and infinity of these controls. The Control.ascx file contains quite a bit of javascript. When the control is rendered by .Net to HTML, you notice that it prints the javascript for each control. This was expected. I'd like to reduce the amount of HTML output by the server to increase page load times. Normally, you could just move the javascript to an external file and then you only need one extra HTTP request which will serve for all controls. But what about instances in the javascript where we have something like document.getElementById('<%= txtTextBox.ClientID %'); How would the javascript know which user control work with? Has anyone done something like this, or is the solution staring me in the face?

  • Adding Street View controls (the two icons just above the +) to a Google Map (v3)

    - by AlexV
    It's probably something really simple, but I can't find it in the docs and I can't find a map with it to check it's source... I use version 3 of the API. I guess it's an something to add in myOptions? var latlng = new google.maps.LatLng(-34.397, 150.644); var myOptions = { zoom: 8, center: latlng, mapTypeId: google.maps.MapTypeId.ROADMAP } map = new google.maps.Map(document.getElementById('map_canvas'), myOptions); Currently I only have dragging controls and the zoom pane controls. I would like to have the two Street View controls icons too. If you want full source, I'm using this example as a base (how would you add Street View controls to this example?).

  • How to get InnerText of IFrame from another site?

    - by Eclipsed4utoo
    I am trying to do some screen-scraping of a website. The content that I want to get is inside of an IFrame. How do I get the InnerText or HTML that is being displayed inside of the IFrame? I am using .Net 4.0 and C#. I want to be able to do this from a WinForm. I tried this, but can't find where to get the actual data from... void PageCompleted(object sender, WebBrowserDocumentCompletedEventArgs e) { WebBrowser b = sender as WebBrowser; string response = b.DocumentText; HtmlElement element = b.Document.GetElementById("profileFrame"); if (element != null) { // do something with the data } } I've tried searching through the element but couldn't find any of the HTML. Is this possible?

  • why won't my ajax work asynchronously

    - by payling
    I'm having trouble understanding why my code will not work asynchronously. When running asynchronously the get_price.php always receives the same $_GET value even though the alert before outputs a unique $_GET value. var arraySize = "<? echo count($_SESSION['items']); ?>"; //get items count var pos = 0; var pid; var qty; getPriceAjax(); function getPriceAjax() { pid = document.cartItemForm.elements[pos].id; //product id qty = document.cartItemForm.elements[pos].value; //quantity alert('Product: ' + pid + ' Quantity: ' + qty); $.ajax({ url:"includes/ajax_php/get_price.php", type:"GET", data:'pid='+pid+'&qty='+qty, async:true, cache:false, success:function(data){ while(pos < arraySize) { document.getElementById(pid + 'result').innerHTML=data; pos++; getPriceAjax(); } } }) }

  • Javascript form validation - multiple form fields larger than 0

    - by calebface
    function negativeValues(){ var myTextField = document.getElementById('digit'); if(myTextField.value < 0) { alert("Unable to submit as one field has a negative value"); return false; } } Above is a Javascript piece of code where every time a field id 'digit' has a value that's less than 0, than an alert box appears either onsubmit or onclick in the submit button. There are about 50 fields in the form that should be considered 'digit' fields where they shouldn't be anything less than 0. What should I change with this Javascript to ensure that all 'digit' like fields have this alert box pop up? I cannot use jquery/mootools for validation - it has to be flat Javascript. Thanks.

  • update element in knockout template which was changed by 3td party library

    - by yakov
    I have 'div' element (recaptchaDiv) in knockout template which is not bound to any observable field: <div id="recaptchaDiv"></div> On the other hand, I update this 'div' by 3rd party library. In particular, this is google recaptcha. This is my code: Recaptcha.create("[my private key]", "recaptchaDiv", { theme: "clean", callback: Recaptcha.ToTest }); And it doesn't work (I see nothing). What I know: trying on FF console: $("#recaptchaDiv").html() - it shows the expected html code, I just can't see it in the browser What I tried: to move recaptchaDiv outside of the template and it works: I can see the captcha in the browser to bind recaptchaDiv on html property: in the template: <div id="recaptchaDiv" data-bind="html: recaptcha"></div> in the model: Recaptcha.create("[my private key]", "recaptchaDiv", { theme: "clean", callback: Recaptcha.ToTest }); recaptcha($("#recaptchaDiv").html()); and it doesn't work (replacing jquery on document.getElementById doesn't help) Any help will be very much appreciated!!! Thank you in advance.
