  • Image not loading from cache after it's loaded in an iframe

    - by Amir
    I'm loading an image in an iframe and then (once the iframe is loaded) loading the image on the page. But most browsers seem to be loading the image twice. Why isn't the img tag being loading from the cache? Something like this: var loader = $('<iframe />').appendTo('body')[0]; loader.onload = function() { $('body').append('<img src="' + imgsrc + '" />'); }; loader.src = imgsrc; http://jsfiddle.net/amirshim/na3UA/ I'm using fiddler2 to see the network traffic. In case you want to know why I want to do this, check out this question

  • why do i lose my hidden field value?

    - by user517406
    Hi, I have some hidden fields on my page, all of which work fine apart from one. I am setting the value in document.ready, before calling buildGrid() : $(document).ready(function() { $.ajax( { type: "POST", url: "/CDServices.asmx/GetWeekEndingDates", data: "{}", dataType: "json", contentType: "application/json; charset=utf-8", success: function(msg) { //store default dates in hidden fields $("#<%=hdnCurrentDate.ClientID%>").val(msg.d.CurrentDate); $("#<%=hdnLastWeekEndingDate.ClientID%>").val(msg.d.LastWeekEndingDate); } }); buildGrid(); }); Yet in buildGrid, the value in the hidden field is empty : function buildGrid() { alert($("#<%=hdnLastWeekEndingDate.ClientID%>").val()); I call other functions on button clicks where the hidden field value is picked up fine, why does the value disappear here?

  • Unable to Use Simple JSOUP Example To Parse Website Table Data

    - by OhNoItsAnOverflow
    I'm attempting to extract the following data from a table via Android / JSOUP however I'm having a bit of trouble nailing down the process. I think I'm getting close to being able to do this using the code I've provided below - but for some reason I still cannot get my textview to display any of the table data. P.S. Live URL's can be provided if necessary. SOURCE: public class MainActivity extends Activity { TextView tv; final String URL = "http://exampleurl.com"; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); tv = (TextView) findViewById(R.id.TextView01); new MyTask().execute(URL); } private class MyTask extends AsyncTask<String, Void, String> { ProgressDialog prog; String title = ""; @Override protected void onPreExecute() { prog = new ProgressDialog(MainActivity.this); prog.setMessage("Loading...."); prog.show(); } @Override protected String doInBackground(String... params) { try { Document doc = Jsoup.connect(params[0]).get(); Element tableElement = doc.getElementsByClass("datagrid") .first(); title = doc.title(); } catch (IOException e) { e.printStackTrace(); } return title; } @Override protected void onPostExecute(String result) { super.onPostExecute(result); prog.dismiss(); tv.setText(result); } } } TABLE: <table class="datagrid"> <tbody><tr> <th>Item No.</th> <th>Name</th> <th>Sex</th> <th>Location</th> </tr> <tr> <td><a href="redirector.cfm?ID=a33660a3-aae0-45e3-9703-d59d77717836&amp;page=1&amp;&amp;lname=&amp;fname=" title="501207593">501207593&nbsp;</a></td> <td>USER1</td> <td>M&nbsp;</td> <td>Unknown</td> </tr> <tr> <td><a href="redirector.cfm?ID=edf524da-8598-450f-9373-da87db8d6c84&amp;page=1&amp;&amp;lname=&amp;fname=" title="501302750">501302750&nbsp;</a></td> <td>USER2</td> <td>M&nbsp;</td> <td>Unknown</td> </tr> <tr> <td><a href="redirector.cfm?ID=a78abeea-7651-4ac1-bba2-0dcb272c8b77&amp;page=1&amp;&amp;lname=&amp;fname=" title="531201804">531201804&nbsp;</a></td> <td>USER3</td> <td>M&nbsp;</td> <td>Unknown</td> </tr> </tbody></table>

  • Phonegap jqm mixing local and server html files

    - by DavidVdd
    I would like to add some online pages to an application keep them up to date without releasing a new store version. For this I taught I could use jqm ajax navigation to load the external page. (I'm aware that might not be allowed for all platforms.) I have set: $.mobile.allowCrossDomainPages = true; $.mobile.pushStateEnabled = false; This seems to work but the problem is that all my href's and $.mobile.ChangePages would have to be changed to <a href='http://mydomain.com/mypage.html'>link</a> $.mobile.changePage('http://mydomain.com/mypage.html'); in stead of <a href='mypage.html'>link</a> $.mobile.changePage('http://mydomain.com/mypage.html'); I was thinking about overriding the changepage method(found this somewhere) to add a domain when the user is online, but the problem is that this method get's called more then once. var originalChangePage = $.mobile.changePage; $.mobile.changePage = function(to, options) { var o = JSON.stringify(o); try { to = to.replace('file:///android_asset/www/', 'http://mydomain.com/'); } catch (err) { //to isn't always filled in. } originalChangePage(to, options); }; Is there a better way to load html pages locally and online using jqm ajax navigation? Extra info: Phonegap/Cordova version 3.5.0 jqm 1.3.2

  • By passing div id, can i change target of text replacement?

    - by crosenblum
    I am using the code below to replace text inside a div. But I need to loop through a specific div, instead of everything on the page, that is the div's text nodes... I just do not understand how to refer to the div in the code below. (function (parent) { var childs = parent.childNodes; // if there are children to this if (childs && childs.length) { // loop through each text node for (var i = 0, node; node = childs[i]; i++) {

  • 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

  • Making a Javascript game, Having a little problem with scrolling.

    - by RobertWHurst
    I have a #wrapper div and a #grid div nested inside. currently I can scroll around with this function below. getCursorPos : function(){ // set the empty cursor object var cursor = {}; //get the offset from the left of the grid container var grid //offset loop $(function getCursorPos(){ grid = $('#grid').offset(); setTimeout(getCursorPos, game.loopSpeed); }); //continuosly get the position var that = this; $(document).mousemove(function(e){ //if game mode is menu exit if(game.mode === 'menu'){ return; } // NOTE: this looks a litle over done but don't remove anything // its like this because javascript uses floating points // and so in order to line up to the nearest hunderedth I // had to make the cursor and div position intergers by // muliplying by ten. one the two are added I reduced them // and rounded them. that.x = Math.round(((e.pageX * 10) - (grid.left * 10)) / 10); that.y = Math.round(((e.pageY * 10) - (grid.top * 10)) / 10); }); }, the problem is that the mouse coordinates only update when the mouse moves. is there any way to get the coordinates with out moving the mouse?

  • Does this incorporate JavaScript closures?

    - by alex
    In trying to learn JavaScript closures, I've confused myself a bit. From what I've gathered over the web, a closure is... Declaring a function within another function, and that inner function has access to its parent function's variables, even after that parent function has returned. Here is a small sample of script from a recent project. It allows text in a div to be scrolled up and down by buttons. var pageScroll = (function() { var $page, $next, $prev, canScroll = true, textHeight, scrollHeight; var init = function() { $page = $('#secondary-page'); // reset text $page.scrollTop(0); textHeight = $page.outerHeight(); scrollHeight = $page.attr('scrollHeight'); if (textHeight === scrollHeight) { // not enough text to scroll return false; }; $page.after('<div id="page-controls"><button id="page-prev">prev</button><button id="page-next">next</button></div>'); $next = $('#page-next'); $prev = $('#page-prev'); $prev.hide(); $next.click(scrollDown); $prev.click(scrollUp); }; var scrollDown = function() { if ( ! canScroll) return; canScroll = false; var scrollTop = $page.scrollTop(); $prev.fadeIn(500); if (scrollTop == textHeight) { // can we scroll any lower? $next.fadeOut(500); } $page.animate({ scrollTop: '+=' + textHeight + 'px'}, 500, function() { canScroll = true; }); }; var scrollUp = function() { $next.fadeIn(500); $prev.fadeOut(500); $page.animate({ scrollTop: 0}, 500); }; $(document).ready(init); }()); Does this example use closures? I know it has functions within functions, but is there a case where the outer variables being preserved is being used? Am I using them without knowing it? Thanks Update Would this make a closure if I placed this beneath the $(document).ready(init); statement? return { scrollDown: scrollDown }; Could it then be, if I wanted to make the text scroll down from anywhere else in JavaScript, I could do pageScroll.scrollDown(); I'm going to have a play around on http://www.jsbin.com and report back

  • Datepicker BeforeShowDay CSS problem with content styling

    - by Darklomba
    I think I'm not the only one having this problem. Whenever I try to apply a BeforeShowDay a new CSS class, the content of the "special date" is not being modified. I tried changing the default theme, adding a new class, but this is affecting only the outside border and not the inside content. Using Firebug I found that the html code being printed is the following: <td class=" ui-state-content ui-state-anulados" onclick="DP_jQuery.datepicker._selectDay('#datepicker',9,2009, this);return false;" title="Paddle"> <a class="ui-state-default" href="#">16</a> </td> So, my class would be ui-state-content ui-state-anulados but I notice that the ui-state-default class is being applied automatically and I suspect that this may be the problem. I really don't know how to solve this. I've been looking inside ui.datepicker.js code and I think I found the line that is giving me this problems. It is line number 1394 and it has the following code. (ui.datepicker.js) (unselectable ? '<span class="ui-state-default">' + printDate.getDate() + '</span>' : '<a class="ui-state-default' + Any clues on how this can be done? Thanks in advance. Manuel.-

  • prettyphoto and nivoslider

    - by Gabriel Ciprian Magda
    I have added the nivoslider and prettyphoto lightbox to a page. What I am trying to do: when you click one of the nivoslider images, prettyphoto should load a video. Everything works ok, except that whenever the nivo slider is sliding the images, the video in prettyphoto lightbox is reloading. How can I prevent the video from reloading once the sliding images are changing? I am not a javascript nija but I am guessing it can be done with changepicturecallback: function(){} from prettyphoto...

  • What's the proper workaround for creating a div with a table in it with images in the table?

    - by Noor
    I want this: <div id="display"> <div id="slideshow1"> <table cellspacing=0><tr><td style="height:200px;padding:0;vertical-align:middle"> <img ... /> </td></tr></table> </div> </div> And I'm using this: var thelistt = localStorage.getItem('thelist') var trt = document.createElement("div"); trt.setAttribute("Id","slideshow1"); trt.className="pics"; $('#display').append(trt); var tble = document.createElement("table"); tble.setAttribute("cellspacing","0"); tble.innerHTML = "<tr><td style='height:200px;padding:0;vertical-align:middle'>"; $('#slideshow1').append(tble); trt.innerHTML += thelistt; This creates a div, then a table, closes the table, then images, then closes div.. Isn't there a smoother way to not do all this, if someone'd take a look at my current code i''m sure you'd get a good laugh : http://hem.bredband.net/noor/bildspelet3.html (you need to click on edit and put in two or more urls directly to images)

  • dynamically changing the selector text

    - by kelly
    I have a 'next' button which fades out a div, shows another, changes out a graphic and then... I want it to change the actual ID of the 'next' button but neither .html nor replaceWith seem to be working. I have this: $(document).ready(function(){ $('#portfolio').fadeTo(500,0.25); $('#account') .animate({width:"10.1875em",height:"11.1875em",duration:'medium'}); $('#next2_btn').click(function(){ $('#content').fadeTo(300, 0.0, function() { $('#content2').show(300, function() { $('#next2_btn').$('#next2_btn'.value).html('<area shape="rect" coords="826,935,906,971" id="next3_btn" href="#">') $('#account').fadeTo(500,1.0) .animate({marginLeft:"220px", width:"2em",'height' :"2em",duration:'medium'}) .animate({     marginLeft:"400px",     marginTop:"35px",     width:"7em",     height:"7em", duration:"medium"     }, 'medium', 'linear', function() {     $('#statusGraphic').replaceWith('<img src="state2_138x28.gif">');     }) .fadeTo(500,0.5); $('#portfolio') .fadeTo(500,1.5) .animate({marginLeft:"-175px", width:"2em",height:"2.5em",duration:'medium'}) .animate({marginLeft:"-330px", width:"8.5em",height:"9.9375em",duration:'medium'}); }); }) })

  • Radio buttons being reset in FF on cache-refresh

    - by Andrew Song
    (This is technically an addendum to an earlier StackOverflow question I had posted, but my original post asked a different question which doesn't really cover this topic -- I don't want to edit my older question as I feel this is different enough to merit its own page) While browsing my website in Firefox 3.5 (and only FF3.5), I come across a page with two radio buttons that have the following HTML code: <input id="check1" type="radio" value="True" name="check" checked="checked"/> <input id="check2" type="radio" value="False" name="check"/> This page renders as expected, with 'check1' checked and 'check2' unchecked. When I then go to refresh the page by pressing Control + R, the two radio buttons render, but they are both unchecked even though the raw HTML code is the same (as above). If I do a cache-miss refresh (via Control + F5 or Control + Shift + R), the page returns back to the way you'd expect it. This is not a problem in any other browser I've tried except FF3.5. What is causing these radio buttons to be reset on a normal refresh? How can I avoid this?

  • Will dynamicaly generated content via Javascript hurt SEO

    - by Luke101
    This is what I would like to do. I would like to load content dynamically. Everything except the actual content will be rendered by javascript. I will place all the require information in a javascript variable or array at the bottom of the page. Then I will use javascript to place the content in the designated area. These are the types of things I would like javascript to render: Login menu Header and logo info Side bar info Footer info Dialog popups Ads All of the MEAT content will not be rendered by javascript. I will use the backend server to put the content in html. My logic is that more of the real content will be in HTML and all the other things will be rendered by javascript. Will this help or hurt SEO?
