  • How do I upload a file when I know the client's filepath?

    - by GJTorikian
    I'm interested in the way Sonic Living detects your iTunes library XML file. It prompts the user to approve its actions, then automatically uploads the XML file based on the client OS (and assuming the default installation path of iTunes). How the heck does it do that? None of the upload libraries I've looked at have this feature. They all assume that a user will click "Select file..." then browse around for the right thing to upload.

  • How to set default view in OpenLayers, WITHOUT restricting bounds?

    - by Jenny
    Based on samples, I can see that you can set a default view in OpenLayers by saying something along the lines of: var bounds = new OpenLayers.Bounds(-125, 25, -65, 50); var map = new OpenLayers.Map('map', {restrictedExtent: bounds }); However, this also (as the name implies), restricts me to be able to ONLY navigate within these bounds. I can zoom out and see things outside of these bounds, but I can't then zoom back onto them, or scroll to them. I've tried not having any restrictedExtent (or making it the entire map), but then I can't get it to focus on the area I want. I tried using: map.setCenter(new OpenLayers.LonLat(0,0), 3); console.log(map.getCenter()); To set the zoom and the center...but it doesn't seem to do ANYTHING, other than set the variable "center" which I can then read from map.getCenter() (if I don't set it, it's null, if I do set it, I can see it...but the map itself stays fully extended and it's center doesn't seem to change at all...) The Map layer I am using is: OpenLayers.Layer.OSM.Mapnik with displayOutsideMaxExtent set to true... I'm really at a loss here. My goal is to have a default region of the world zoomed in to and in view (such as the United States), with the option of viewers being able to go outside the default to view things.

  • Facebook call back function with timeout

    - by Dirty Bird Design
    So I've been getting my ass kicked pretty good with Facebook's moving target of an API. I need to display some hidden content after a person clicks 'like' on a landing page. I can somewhat get this to work, when the user clicks 'like' the normal fb dialogue appears and then goes away immediately and content is displayed. I have 'achieved' this with the following js. <script> FB.Event.subscribe('edge.create', function(href, widget) { document.getElementById('goodies').style.display = "block"; document.getElementById('fb-content').style.display= "block"; document.getElementById('copy').style.display = "none"; }); </script> I cannot find any documentation about a callback event after someone hits "post to facebook" or after the dialogue closes, only afte they hit like. How would I incorporate a setTimeout function into this to give people some time to fill out the fb dialogue? thanks. If anyone has a better way to do this I'm all ears. This is for a business page and I cannot seem to add an app to get an app ID anymore so the API is pretty useless to me at this point. Also, if the url to be liked is a fb page, the callbacks don't seem to fire. Other code used: <html xmlns:fb="http://ogp.me/ns/fb#"> <div id="fb-root"></div> <script>(function(d, s, id) { var js, fjs = d.getElementsByTagName(s)[0]; if (d.getElementById(id)) return; js = d.createElement(s); js.id = id; js.src = "//connect.facebook.net/en_US/all.js#xfbml=1"; fjs.parentNode.insertBefore(js, fjs); }(document, 'script', 'facebook-jssdk')); </script> <fb:like href="onlynonfburl.com" send="false" layout="button_count" width="450" show_faces="false" font="arial"></fb:like>

  • How to remove options from select element using jquery?

    - by Lapa
    I have n drop-downs like this: <select id="select1"> <option>1</option> <option>2</option> <option>3</option> </select> <select id="select2"> <option>1</option> <option>2</option> <option>3</option> </select> with identical options. All the choices should be unique, so once the option is selected in one combobox, it should be removed from others. Now, http://stackoverflow.com/questions/877328/jquery-disable-select-options-based-on-radio-selected-need-support-for-all-brows offers a nice solution, but how can I modify this to work with selects instead of radio buttons?

  • how to disable an onclick event?

    - by user1819709
    <form id="QandA" action="<?php echo htmlentities($action); ?>" method="post"> <table id="question"> <tr> <td colspan="2"> <a onclick="return plusbutton();"> <img src="Images/plussign.jpg" width="30" height="30" alt="Look Up Previous Question" class="plusimage" id="mainPlusbutton" name="plusbuttonrow"/> </a> <span id="plussignmsg">(Click Plus Sign to look up Previous Questions)</span> </td> </tr> </table> </form> In the code above I am able to replace an image with another image when the if statement is met. But my problem is that when the image is replaced, it does not disable the on click event. My question is that when the image is replaced, how do I disable the onclick event onclick="return plusbutton();?

  • Tabs.url is undefined

    - by Notionwork
    I have no clue what I'm doing wrong here! This should be working I believe. I'm writing a chrome extension and this should get the current tab's url and set the html of #current-tab to the url (for testing purposes). The code successfully gets to the callback, but it says that tab.url is undefined when I put it in an alert box, and it does not put it's value in #current-tab. Here's the code I have: $('#get-tab').click(function(){ chrome.tabs.query({"active" : true}, function(tab){ for (var i = 0; i < tab.length; i++) { alert(tab.url); $('#current-tab').append(tab.url); }; }); });

  • why my array is losing it's contents when I refresh the page?

    - by Fernando SBS
    I have created an: var checkboxFarm = new Array(); then I want to record a checkbox status in that array, as there are 11 checkboxes. Button.addEventListener("click", function() { rp_farmAtivada(index); }, false); when clicked change the variable in the array: function rp_farmAtivada(index) { checkboxFarm[index] = !checkboxFarm[index]; }; but every time I refresh the page it loses all the checkboxes status and I'm aware that all that array gets the "undefined" value. the checkboxFarm array is defined in the beginning of the script, so it should have a global scope. Am I missing something?

  • Iterating Through a jQuery Object Array

    - by DeltaFox
    I know this has been asked and answered a couple times already, but I'm still confused about how to reference the current object when iterating over a jQuery array. For example, the following code gives me the error "TypeError: genH3Array[i].next is not a function". What is the right way to reference the current array object? var genH3Array = $('#Generation_II').parent(); genH3Array.push($('#Generation_III').parent());; genH3Array.push($('#Generation_IV').parent()) $.each(genH3Array, function(i, value) { if(genH3Array[i].next().attr("align") == "center") { genH3Array[i].next().next().next().insertBefore(heading.next()) } genH3Array[i].next().next().insertBefore(heading.next()) genH3Array[i].next().insertBefore(heading.next()) })

  • Uncaught syntax error: Adding <li> elements to an <ul>

    - by ThePagan
    I keep getting an uncaught syntex error which I know usually means your code has a missing closing something. I keep failing to see what it is that I am missing. The idea of the function is that it extracts the a links ID and Text content and add's it to an un-ordered list. The links have a class of 'ingredient_add' and the unordered list has an ID of 'ingredientsAdded'. I can't see what I've missed here. $(document).ready(function() { $('.ingredient_add').click(function() { event.preventDefault(); var id = this.id; var value = this.text(); $('#ingredientsAdded').append("<li id='"+id+"'>"+value+"</li>"); }); //end add to list }); // end document ready()

  • How to read & write contents of a div from localstorage in chrome extensions?

    - by Minas Abovyan
    I am trying to build an extension that will allow users to put some parameters into a text box in the popup, generate a link using that information and add it to the said popup. I have all that working, but needless to say, it gets flushed every time the user opens the extension anew. I'd like the info that has been put in there to stay, but can't seem to get it to work. Here's what I have thus far: manifest.json { "manifest_version": 2, "name": "Test", "description": "Test Extension", "version": "1.0", "permissions": [ "http://*/*", "https://*/*" ], "browser_action": { "default_title": "This is a test", "default_popup": "popup.html" } } popup.html <!DOCTYPE html> <html> <head> </head> <body> <div id="linkContainer"/> <input type="text" id="catsList"/> <button type="button" id="addToList">Add</button> <script src="popup.js"></script> </body> </html> popup.js function addCats() { var a = document.createElement('a'); a.appendChild(document.createTextNode(document.getElementById('catsList').value)); a.setAttribute('href', 'http://google.com'); var p = document.createElement('p'); p.appendChild(a) document.getElementById('linkContainer').appendChild(p); indexLinks() } function indexLinks() { var links = document.getElementsByTagName("a"); for (var i = 0; i < links.length; i++) { (function () { var ln = links[i]; var location = ln.href; ln.onclick = function () { chrome.tabs.create({active: true, url: location}); }; })(); } }; document.getElementById('addToList').onclick = addCats; My guess is that I need something along the lines of localStorage['cointainer'] = document.getElementById('linkContainer'); at the end of addCats() and a call to something like function loadLocalStorage() { var container = document.getElementById('linkContainer'); container.innerHTML = localStorage['container']; } at the beginning, but doing that didn't work. Not sure what's going wrong. Also,if there is a different way to save users' additions, I'd be open to them.

    Hi, My DOM looks like this: <div id="d1"> <div class="c1"> <a href="#"><img src="img1_on.gif"></a> <a href="#"><img src="img2_on.gif"></a> </div> </div> When anyone clicks on an image, I want the image src to change to where x represents the image number 1 or 2. Is this possible or do I have to use CSS to change the images?

  • 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

    Hello, var Dog = function(name) { this.name = name; this.sayName(); } Dog.prototype.sayName = function() { alert(this.name); } I'm creating new instance of Dog object, but method sayName() is undefined. Why? Or maybe I should do something like (but I can't see difference)... var Dog = function(name) { this.name = name; this.prototype.sayName = function() { alert(this.name); } } Thank you.

  • JQuery addclass to another div (but not parent) if no data is found

    - by Danny
    I have this to add a class to the main table that the report is in if there is no data returned. $('#report-area table td:contains("Sorry, your search did not return any data")').parents('#reportArea').addClass('no-report-data') However, I have another div area "#report-footer" but it's not inside #report-area. I'd like to also add the .no-report-data class to "#report-footer" as well but in this case I don't think the .parents selector will work. Is there another selector I can use to do this?

  • browser instant updates with ajax/jquery

    - by wcpro
    I'm trying to reverse engineer how facebook handles their notifications, where when you get a message you get instantly notified via the browser. I've fiddled with it for a little bit and realized that there is always a pending GET request "listening" if you will to some sort of update from the server. This appears to be some sort of observer pattern. I was just wondering if this pattern was documented somewhere.

    Hello, we're facing a problem now. We have a pretty big page with a loooong inline script, which does all the work. We now want to obfuscate it and use it as a separate .js file. But the problem is that we have paths which are generated by Url helper (Url.Content()). So what is the best way to separate js file from the page and not using hard-coded path strings?

  • Margin for select option in IE and chrome is not working

    I am setting a css class to some select options in JS. This class includes margin style. It is working in the FF but not in IE and chrome. window.onload = function() { replace('edit-field-region-tid'); replace('edit-tid'); } function replace(id) { var i = 0; var s = document.getElementById(id); for (i; i < s.options.length; i++) { if (find(s.options[i].text, id, i)) { s.options[i].setAttribute("class", "sub_options"); } } } function find(str, id, option_id) { var i; var s = document.getElementById(id); for (i = 0; i < str.length; i++) { if (str.charAt(i) == '-') { s.options[option_id].text = str.cutAt(0, ""); return true; } } return false; } String.prototype.cutAt = function(index, char) { return this.substr(index+1, this.length); } And CSS: .sub_options{ margin-left:20px; text-indent:-2px; } Any ideas thanks!
