  • mutidimensional array from javascript/jquery to ruby/sinatra

    - by user199368
    Hi, how do I pass a 2-dimensional array from javascript to ruby, please? I have this on client side: function send_data() { var testdata = { "1": { "name": "client_1", "note": "bigboy" }, "2": { "name": "client_2", "note": "smallboy" } } console.log(testdata); $.ajax({ type: 'POST', url: 'test', dataType: 'json', data: testdata }); } and this on server side: post '/test' do p params end but I can't get it right. The best I could get on server side is something like {"1"=>"[object Object]", "2"=>"[object Object]"} I tried to add JSON.stringify on client side and JSON.parse on server side, but the first resulted in {"{\"1\":{\"name\":\"client_1\",\"note\":\"bigboy\"},\"2\":{\"name\":\"client_2\",\"note\":\"smallboy\"}}"=>nil} while the latter has thrown a TypeError - can't convert Hash into String. Could anyone help, or maybe post a short snippet of correct code, please? Thank you

  • Flash AS2.0 and JavaScript/jQuery (ExternalInterface) Communication

    - by abysslogic
    Hi there, Im trying to use JS to send data to my Flash AS2.0 music player with ExternalInterface, except there are no good tutorials or guides on ExternalInterface that I can find. I want to be able to change the current song in the player by clicking a JavaScript link, and on page / window load without clicking, play a default song. I dont need a super complicated answer on loading sounds in flash, etc., I am just having a lot of difficulties getting JS to send anything to Flash, and when I get that to work - would I need to put some if / else into the flash to determine if the link has been clicked or not? Thanks edit heres the code as of now: AS 2.0 import flash.external.ExternalInterface; ExternalInterface.addCallback('loadSong', null, flashFunction); function flashFunction (val) { extra = val; } JavaScript var flashObj = document.getElementById('VSPLAYER'); function loadSong(val) { return val } HTML <a href="javascript:loadSong('2')">Play song 2</a> <object id="VSPLAYER" type="application/x-shockwave-flash" data="vs_player.swf" width="280" height="90"> <param name="movie" value="vs_player.swf" /> <param name="allowscriptaccess" value="always" /> </object>

  • Python form POST using urllib2 (also question on saving/using cookies)

    - by morpheous
    I am trying to write a function to post form data and save returned cookie info in a file so that the next time the page is visited, the cookie information is sent to the server (i.e. normal browser behavior). I wrote this relatively easily in C++ using curlib, but have spent almost an entire day trying to write this in Python, using urllib2 - and still no success. This is what I have so far: import urllib, urllib2 import logging # the path and filename to save your cookies in COOKIEFILE = 'cookies.lwp' cj = None ClientCookie = None cookielib = None logger = logging.getLogger(__name__) # Let's see if cookielib is available try: import cookielib except ImportError: logger.debug('importing cookielib failed. Trying ClientCookie') try: import ClientCookie except ImportError: logger.debug('ClientCookie isn\'t available either') urlopen = urllib2.urlopen Request = urllib2.Request else: logger.debug('imported ClientCookie succesfully') urlopen = ClientCookie.urlopen Request = ClientCookie.Request cj = ClientCookie.LWPCookieJar() else: logger.debug('Successfully imported cookielib') urlopen = urllib2.urlopen Request = urllib2.Request # This is a subclass of FileCookieJar # that has useful load and save methods cj = cookielib.LWPCookieJar() login_params = {'name': 'anon', 'password': 'pass' } def login(theurl, login_params): init_cookies(); data = urllib.urlencode(login_params) txheaders = {'User-agent' : 'Mozilla/4.0 (compatible; MSIE 5.5; Windows NT)'} try: # create a request object req = Request(theurl, data, txheaders) # and open it to return a handle on the url handle = urlopen(req) except IOError, e: log.debug('Failed to open "%s".' % theurl) if hasattr(e, 'code'): log.debug('Failed with error code - %s.' % e.code) elif hasattr(e, 'reason'): log.debug("The error object has the following 'reason' attribute :"+e.reason) sys.exit() else: if cj is None: log.debug('We don\'t have a cookie library available - sorry.') else: print 'These are the cookies we have received so far :' for index, cookie in enumerate(cj): print index, ' : ', cookie # save the cookies again cj.save(COOKIEFILE) #return the data return handle.read() # FIXME: I need to fix this so that it takes into account any cookie data we may have stored def get_page(*args, **query): if len(args) != 1: raise ValueError( "post_page() takes exactly 1 argument (%d given)" % len(args) ) url = args[0] query = urllib.urlencode(list(query.iteritems())) if not url.endswith('/') and query: url += '/' if query: url += "?" + query resource = urllib.urlopen(url) logger.debug('GET url "%s" => "%s", code %d' % (url, resource.url, resource.code)) return resource.read() When I attempt to log in, I pass the correct username and pwd,. yet the login fails, and no cookie data is saved. My two questions are: can anyone see whats wrong with the login() function, and how may I fix it? how may I modify the get_page() function to make use of any cookie info I have saved ?

  • input type="text" not clickable in a jcarousel (jQuery based carousel) element

    - by AkaiKen
    Hello ! I work on a website where almost all objects are in a jCarousel element : <div> <ul id="mycarousel"> <li>object 1</li> <li>object 2</li> </ul> </div> is the "written" code, and : <div class=" jcarousel-skin-tango"> <div class="jcarousel-container jcarousel-container-horizontal" style="display: block;"> <div class="jcarousel-prev jcarousel-prev-horizontal jcarousel-prev-disabled jcarousel-prev-disabled-horizontal" style="display: block;" disabled="true"></div> <div class="jcarousel-next jcarousel-next-horizontal" style="display: block;" disabled="false"></div> <div class="jcarousel-clip jcarousel-clip-horizontal"> <ul class=" jcarousel-list jcarousel-list-horizontal" id="mycarousel" style="width: 2853px; left: 0px;"> <li class="jcarousel-item jcarousel-item-horizontal jcarousel-item-1 jcarousel-item-1-horizontal" jcarouselindex="1" style="width: 307px;"> object 1 </li> <li class="jcarousel-item jcarousel-item-horizontal jcarousel-item-1 jcarousel-item-1-horizontal" jcarouselindex="1" style="width: 307px;"> object 2 </li> </ul> </div> </div> is the generated code (here it lacks the ultimate </div>, maybe a number of rows limitation ?). I'm sorry I can't provide a link, I work on a local server currently. It works perfectly =) but... my problem is : an <input type="text" /> won't be clickable in this environment. I tried the others type of input, radio, checkbox, file : works. But text does not. I can specify a value on my input (it's its purpose on my work : a search in a database for datas to be modified and reinjected in database). In fact, I can access to the text input by clicking-right in then left. But it's pretty 'unergonomic', and in my project it's unthinkable. Ah, and I tried to style this input with a style="z-index:1000;", no changes, I think it's not a CSS problem. Does anybody have an idea ? Thank you very much in advance.

  • Javascript - how to change elements content inside a page when using iframes, using dom, not jquery

    - by Erez
    Hello all, I have this iframe and as u can see it call a js function with the onload trigger. <iframe name="top" id="top" width="99%" height="20%" src="top.htm" frameborder="0" scrolling="no" onload="log_in()"></iframe> What i need to do is to effect the element inside "top.htm" (change innerHTML and stuff like that) from that function. But the problem is that the funnction does not recognize the elements of the "top.htm" page, only the ones in index.htm (the page with the iframes). p.s. i have to use DOM and i have to use iframes. Any one knows how to do that? 10x :-)

  • JQUERY clickout side element

    - by Val
    I have multiple menues on my page... <div class="menu"> <div>Menu header</div> <div>Menu content</div>// should hide on click outside .menu </div> <div class="menu"> <div>Menu header</div> <div>Menu content</div>// should hide on click outside .menu </div> basically i need all the menu(s) to hide when a click is detected unless someone is clicking any of the menues it should hide any other menu(s) apart from the menu they clicked on. I have seen a few that work but only if you have one menu on the page which is not exactly useful using stopPropagation as it may cancel any other necessary instructions; any ideas would be appriciated.

  • Chrome extensions: Content script (jQuery) in Youtube does not work properly

    - by Fabian
    I have this: $(document).ready(function() { $("button.yt-uix-expander-arrow").attr("id", "yt-uix-expander-arrow"); $("#yt-uix-expander-arrow").mouseover(function() { alert("Hello"); }); }); injected into Youtube. Using right click inspect element, the <button class="yt-uix-expander-arrow"> has a id="yt-uix-expander-arrow" attribute successfully added to it. However the mouseover event does not trigger. However if I were to change $("#yt-uix-expander-arrow").mouseover() to $(".yt-uix-expander-arrow").mouseover() it works. That's very unusual, because the #yt-uix-expander-arrow id has already been added to the button element. I tested it out on Facebook, adding a id to a class and doing a mouseover() event on the ID and it works. Any idea?

  • JavaScript - Why does google-maps wait until jquery finishes download?

    - by Teddyk
    I'm using the following Google Maps autload (asynchronous) to load asynchronous both Google Maps v3 and JQuery, like so: <script type="text/javascript" src="http://www.google.com/jsapi?autoload={ "modules":[ {name:"maps",version:3,other_params:"sensor=false"},{"name":"jquery","version":"1.4.2"},{"name":"jqueryui","version":"1.8.1"} ]}"></script> However, looking at the network traffic, it appears that it is not downloading asynchronously. Question: Does anyone understand why the %7Bcommon (google-maps) file is being delayed from download until the jquery-ui.min file completes download first?

When I drag an element over the dialog that is over a droppable <td, then elements drops inside it even if it is still being dragged over the dialog.

  • Hosting Javascript/CSS file on CDN similar to Google hosting jQuery

    - by Alec Smart
    Hello, I am wondering if there are any hosts or if I can host my file (JS & CSS) on Google so that they are cached and load real quick (due to CDN and gzip). A number of my customers use these files and I would prefer if they could somehow include this to file to receive the JS file. Ideally with filename.js?publickey=sdfgsdfg (which will be tied to a particular domain name). The problem is that my hosting needs are very small- only about 100kb. Any suggestions. My problem is that the customers using the JS & CSS file, have no clue about gzipping content or caching (as their shared hosts do not support it), as a result causes the JS/CSS to take forever to load. Am wondering if I can leverage an existing free service, or I do not mind paying either. Thank you for your time.

    After you enter your name and password on a website, a cookie is stored on your computer. Your computer then sends information from that cookie to the website whenever you browse to another page on that site so that the site knows who you are. How is information from the cookie sent? Does the browser append information from within the cookie to the html address?
