  • Creating Dynamic variables from json response

    - by c0mrade
    My JSON response looks like this : {"sample":[{"id":"2","name":"branch name"},{"id":"3","name":"branch name 2"}]} My function looks like this : function getJSONObjects(){ $.getJSON("http://localhost/api/branches", function(data){ $.each(data.sample, function(i,item){ var loc = "branch"; eval("var " + loc + item.id + "=123;"); alert(loc + item.id); }); }); } The idea is to create branch + id object so I can do something with it(create marker on a map), so I tried to assign it any value to see if this was working. I wanted both branch2 and branch3 to alert 123 so I have something to start with. But currently this alerts branch2 and branch3 instead of 123. I have little experience with creating dynamic variables/objects can someone tell me what I'm doing wrong or maybe another approach towards solving this?

  • Blogger Code Image linking to post page

    - by Jm Agas
    Is this possible to achieve in blogger? My goal is to make Static page images to become clickable and link it to the actual post page. I know its possible by editing each post but I want to make it automatic. For example: In 9gag.com when you click the image from the homepage it will actually link you to the post page. I want to do the same but in blogger. Something like this <b:if cond='data:blog.pageType != &quot;static_page&quot;'><a expr:href='data:post.url'><static page images></a></b:if> Screenshot: http://i.stack.imgur.com/YAWkL.jpg

  • Creating a jQuery plugin: best practices regarding functions' visibility?

    - by marcgg
    I'm creating a jQuery plugin. So far it's working fine, but I'm having doubt about the way I'm doing things: jQuery.fn.myMethod = function() { return this.each(function(){ MyScope.doSomething(jQuery(this).attr("id")); }); }; var MyScope = { doSomething: function(id){ // something doSomethingElse(23); // some more code doSomethingElse(55); }, doSomethingElse: function(someInt){ // some code } }; I use MyScope to store all my "private" functions. I don't want the user to be able to go $("p").doSomething(), but I do need to use them. I could move everything in the myMethod function, but it would create a 100 lines long function and people would hate me for it. What's the best practices in this situation? Are there any great tutorials out there regarding this?

  • How to store session values with Node.js and mongodb?

    - by Tirithen
    How do I get sessions working with Node.js, [email protected] and mongodb? I'm now trying to use connect-mongo like this: var config = require('../config'), express = require('express'), MongoStore = require('connect-mongo'), server = express.createServer(); server.configure(function() { server.use(express.logger()); server.use(express.methodOverride()); server.use(express.static(config.staticPath)); server.use(express.bodyParser()); server.use(express.cookieParser()); server.use(express.session({ store: new MongoStore({ db: config.db }), secret: config.salt })); }); server.configure('development', function() { server.use(express.errorHandler({ dumpExceptions: true, showStack: true })); }); server.configure('production', function() { server.use(express.errorHandler()); }); server.set('views', __dirname + '/../views'); server.set('view engine', 'jade'); server.listen(config.port); I'm then, in a server.get callback trying to use req.session.test = 'hello'; to store that value in the session, but it's not stored between the requests. It probobly takes something more that this to store session values, how? Is there a better documented module than connect-mongo?

  • Why does my Google maps api v3 and side panel not fill my page upon resizing?

    - by Gavin
    I'm developing a web page and I have a side panel on the left with a search bar and a Google maps api v3 filling the rest of the page to the right. When I make the browser very small vertically, there is a white space between the side panel and the map, and the bottom of the browser. However, the text continues to the bottom of the browser. It looks like: Here's my css code: <style type="text/css"> body {margin:0;} #panel {height:100%; width:300px; position:absolute; padding:0;background-color:#8C95A0;} #header {padding:2px; text-align:center} #address_instruction {position:relative; top:7%; padding:2px; text-align:center} #geocoder {position:relative; top:8%; padding:2px; text-align:center} #toggle_instruction {position:relative; top:22%; padding:2px; text-align:center} #layers {position:relative; top:25%; padding:2px; text-align:center} #layer0 {padding:2px; text-align:center} #layer1 {padding:2px; text-align:center} #layer2 {padding:2px; text-align:center} #link {top:50%; position:relative; padding:2px; text-align:center} #map_canvas {height:100%; left:300px; right:0px; position:absolute; padding:0;} </style> The IDs within #panel refer to the items on the left hand side in the panel. Why don't the side panel background color and map extend to the bottom of the browser?

  • JSP: Refresh ComboBox options

    - by framara
    Hi, There's a class 'Car' with brand and model as properties. I have a list of items of this class List<Car> myCars. I need to represent in a JSP website 2 ComboBox, one for brand and another for model, that when you select the brand, in the model list only appear the ones from that brand. I don't know how to do this in a dynamic way. Any suggestion where to start? Thanks Update Ok, what I do now is send in the request a list with all the brand names, and a list of the items. The JSP code is like: <select name="manufacturer" id="id_manufacturer" onchange="return getManufacturer();"> <option value=""></option> <c:forEach items="${manufacturers}" var="man"> <option value="${man}" >${man}</option> </c:forEach> </select> <select name="model" id="id_model"> <c:forEach items="${mycars}" var="car"> <c:if test="${car.manufacturer eq man_selected}"> <option value="${car.id}">${car.model}</option> </c:if> </c:forEach> </select> <script> function getManufacturer() { man_selected = document.getElementById('id_manufacturer').value; } </script> How do I do to refresh the 'model' select options according to the selected 'man_selected' ?

  • Simple iframe editor and oninput event.

    - by teehoo
    I'm writing a simple editor in an iframe, but having trouble registering the "oninput" event to detect when the user modifies the text field such as pasting in data etc. var txtArea = document.getElementById('txtArea'); txtArea.contentWindow.document.designMode="on"; txtArea.contentWindow.document.open(); txtArea.contentWindow.document.write("body{font-size:13px;}"+data.document+""); txtArea.contentWindow.document.close(); $([txtArea.contentWindow.document]).bind("click", updateCaretPosMouse); //fires $([txtArea.contentWindow.document]).bind("keyup", updateCaretPosKeyboard); //fires $([txtArea.contentWindow.document]).bind("input", textChanged); //doesn't fire If I create a plain old textarea element, and add the "input" event to this, then it works. Do 'input" events not work with iframes WYSIWYG editors?

  • Javscript filter vs map problem

    - by graham.reeds
    As a continuation of my min/max across an array of objects I was wondering about the performance comparisons of filter vs map. So I put together a test on the values in my code as was going to look at the results in FireBug. This is the code: var _vec = this.vec; min_x = Math.min.apply(Math, _vec.filter(function(el){ return el["x"]; })); min_y = Math.min.apply(Math, _vec.map(function(el){ return el["x"]; })); The mapped version returns the correct result. However the filtered version returns NaN. Breaking it out, stepping through and finally inspecting the results, it would appear that the inner function returns the x property of _vec but the actual array returned from filter is the unfiltered _vec. I believe my usage of filter is correct - can anyone else see my problem?

  • Printable Version of Google Visualizations DataTable

    - by maleki
    I have a custom routing application that takes information for a route from google maps. It then creates a Google Visualizations DataTable to hold all the steps in the route. My current problem is that in order to reduce overflow for very large routes, I have enabled paging in the options of the DataTable. This leads to a not so printer friendly version because only the portion of the data that is shown in the table will be printed. The other portions of the table are loaded dynamically by the API when you click prev and next. Is there a not so hard way to get the DataTable to be printer friendly when it comes time without sacrificing the ability to have paging enabled?

  • Are google chrome extension "content" scripts sandboxed?

    - by jabapyth
    I was under the impression that the content_scripts were executed right on the page, but it now seems as though there's some sandboxing going on. I'm working on an extension to log all XHR traffic of a site (for debugging and other development purposes), and in the console, the following sniff code works: var o = window.XMLHttpRequest.prototype.open; window.XMLHttpRequest.prototype.open = function(){ console.log(arguments, 'open'); return o.apply(this, arguments); }; console.log('myopen'); console.log(window, window.XMLHttpRequest, window.XMLHttpRequest.prototype, o, window.XMLHttpRequest.prototype.open); This logs a message everytime an XHR is sent. When I put this in an extension, however, the real prototype doesn't get modified. Apparently the window.XMLHttpRequest.prototype that my script is seeing differs from that of the actual page. Is there some way around this? Also, is this sandboxing behavior documented anywhere? I looked around, but couldn't find anything.

  • Tag-like autocompletion and caret/cursor movement in contenteditable elements.

    - by jimeh
    I'm working on a jQuery plugin that will allow you to do @username style tags, like Facebook does in their status update input box. My problem is, that even after hours of researching and experimenting, it seems REALLY hard to simply move the caret. I've managed to inject the <a> tag with someone's name, but placing the caret after it seems like rocket science, specially if it's supposed work in all browsers. And I haven't even looked into replacing the typed @username text with the tag yet, rather than just injecting it as I'm doing right now... lol There's a ton of questions about working with contenteditable here on Stack Overflow, and I think I've read all of them, but they don't really cover properly what I need. So any more information anyone can provide would be great :)

  • Jquery SimpleModal flickers in Firefox

    - by Obay
    I'm using SimpleModal plugin for Jquery and I have a weird problem with Firefox ( other browsers work fine: Chrome, Safari, Opera, IE). What happens is when I click on the button that launches the modal dialog, before showing the modal (and the fadeIn of the overlay), there is a quick "flicker", less than half a second. (It's longer on my slower PC). Weird thing is, it didn't happen in Firefox 3.5.2, but when I upgraded to 3.6.3, I got the flicker. Any ideas? Here is my code: $("#popup").modal({ onOpen: function (dialog) { dialog.data.show(); dialog.container.show(); dialog.overlay.fadeIn('fast'); }, onClose: function (dialog) { dialog.data.hide(); dialog.container.hide(); dialog.overlay.fadeOut('fast', function() { $.modal.close(); }); } });

  • How to display the dynamically created elements for some time?

    - by Holicreature
    i have some rows of data displayed in a table and on mouse over of each row i've list two buttons inside a div element and then display it for some time. And i've associated some functions to be called on clicking the buttons that are dynamically created and displayed elements.. So what i did was i wrote a function which will create elements dynamically and place them exactly where i wanted using styles. And i wrote another function which will remove these dynamically added elements. I called them on mouseover and mouseout events of the row. now when i move mouse out the row to click the button they get disappeared bcoz of my mouseout function. So how can i proceed this? And what is the perfect method to create these kind of stuffs?

  • Why am I losing my characters from my html string when trying to add html dynamically using javascri

    - by Hamman359
    I have a page that I am trying to dynamically add some links to. The links are getting added to the page fine, but the '[' and ']' at either end of the line are getting dropped. The code from my .js file is: var html = "[ <a href='#'>Change</a>&nbsp;|&nbsp;<a href='#'>Remove </a> ]"; $(html).appendTo("#id123"); The result I want is: [ <a href='#'>Change</a>&nbsp;|&nbsp;<a href='#'>Remove</a> ] The result I'm getting is: <a href='#'>Change</a>&nbsp;|&nbsp;<a href='#'>Remove</a> If I wrap the line in a <span> tag like so: var html = "<span>[ <a href='#'>Change</a>&nbsp;|&nbsp;<a href='#'>Remove </a> ]</span>"; $(html).appendTo("#id123"); it renders as expected. I set a breakpoint on the code and checked the html var right before the .appendTo and it contains the '[' and ']'. Anyone know why this is happening? Are '[' and ']' special character that need escaped and I'm just forgetting that fact?

  • When is a Google Maps API key required?

    - by Thomas
    Recently Google changed it's policy on the use API keys. You're now supposed to no longer need an API key to place Google Maps on your website. And this worked perfectly. But now I have this map (without API key) running on my localhost, which works fine. But as soon as I place it online, I get a popup saying that I need another API key. And on another page on that website, Google Maps does work. Could it maybe have something to do with that the map that doesn't work have a lot (30+) of markers on it? Actually using an API key wouldn't be a very nice solution to me, as this is part of a Wordpress plugin used on many websites.

  • Can I embed video on external sites while still using tokens to protect the content?

    - by JKS
    On our own website, it's easy to protect against direct links to our video content by grabbing a token through AJAX and verifying the token through PHP before the file download is started. However I'm also researching how I could provide an embed feature, like YouTube or vimeo etc., without compromising this security feature. The problem is that the embed code I want to provide should look something like <object>...<embed>...</embed></object> -- but I don't know how to grab and append the token to the filename. I mean, I guess I could attach a script that did some gnarly JNOP business, but that's too dirty. I'm using JW Player for the actual video container. Huge thanks to anyone who can help...
