  • python interactive web data/forms/interface communicating with remote server

    - by decipher
    What's an efficient method (preferably simple as well) for communicating with a remote server and allowing the user to 'interact' with it (IE submit commands, user interface) via the web browser (IE a text box to input commands, and an text area for output, or various command-less abstracted interfaces)? I have the 'standalone' python code finished for communicating and working(terminal/console based right now). My primary concern is with re-factoring the code to suite the web, which involves establishing a connection (python sockets), and maintaining the connection while the user is logged on. some further details: currently using django framework for the basic back end/templates.

  • Test for empty jQuery selection result

    - by fsb
    Say I do var s = $('#something'); and next I want to test if jQuery found #something, i.e. I want to test if s is empty. I could use my trusty isempty() on it: function isempty(o) { for ( var i in o ) return false; return true; } Or since jQuery objects are arrays, I suppose I could test s.length. But neither seem quite in the idiom of jQuery, not very jQueryesque. What do you suggest?

  • JScript JSON Object Check

    - by George
    I'm trying to check if json[0]['DATA']['name'][0]['DATA']['first_0'] exists or not when in some instances json[0]['DATA']['name'] contains nothing. I can check json[0]['DATA']['name'] using if (json[0]['DATA']['name'] == '') { // DOES NOT EXIST } however if (json[0]['DATA']['name'][0]['DATA']['first_0'] == '' || json[0]['DATA']['name'][0]['DATA']['first_0'] == 'undefined') { // DOES NOT EXIST } returns json[0]['DATA']['name'][0]['DATA'] is null or not an object. I understand this is because the array 'name' doesn't contain anything in this case, but in other cases first_0 does exist and json[0]['DATA']['name'] does return a value. Is there a way that I can check json[0]['DATA']['name'][0]['DATA']['first_0'] directly without having to do the following? if (json[0]['DATA']['name'] == '') { if (json[0]['DATA']['name'][0]['DATA']['first_0'] != 'undefined') { // OBJECT EXISTS } }

  • Hiding <option>s in IE

    - by Mark
    I wrote this nifty function to filter select boxes when their value is changed... $.fn.cascade = function() { var opts = this.children('option'); var rel = this.attr('rel'); $('[name='+rel+']').change(function() { var val = $(this).val(); var disp = opts.filter('[rel='+val+']'); opts.filter(':visible').hide(); disp.show(); if(!disp.filter(':selected').length) { disp.filter(':first').attr('selected','selected'); } }).trigger('change'); return this; } It looks at the rel property, and if the element indicated by rel changes, then it filters the list to only show the options that have that value... for example, it works on HTML that looks like this: <select id="id-pickup_address-country" name="pickup_address-country"> <option selected="selected" value="CA">Canada </option> <option value="US">United States </option> </select> <select id="id-pickup_address-province" rel="pickup_address-country" name="pickup_address-province"> <option rel="CA" value="AB">Alberta </option> <option selected="selected" rel="CA" value="BC">British Columbia </option> <option rel="CA" value="MB">Manitoba </option>... </select> However, I just discovered it doesn't work properly in IE (of course!) which doesn't seem to allow you to hide options. How can I work around this?

  • Resizing image to fit its container

    - by jack moore
    #foo {width: 300px; height: 400px; overflow: hidden;} <div id="foo"></div> this.someimage = randomImageUrl; $("foo").innerHTML = "<img src='"+this.someimage+"' class='fooimage' />"; Now, the picture could be 200x200 or 1100x400 ... it's totally random. I can just stretch it (or reduce its size) by using: .fooimage {width: 300px; height: 400px;} $("foo").innerHTML = "<img src='"+this.someimage+"' class='fooimage' />"; Or I could test its size: imgHeight = newImg.height; imgWidth = newImg.width; ... and maybe something like this: if(imgHeight >400){ $("foo").innerHTML = "<img src='"+this.someimage+"' height='400' />"; } and browsers will do the rest. But there must be something better. Any ideas? Thanks! :)

  • Move rotating image along Canvas

    - by fatnic
    Hi. I've managed to make an image rotate on my canvas. And I've managed to make an image move along the canvas. My problem now is making it do both. I have got it working but I seems a bit like a hack. I've posted a demo online Here's the code. var cnv = document.getElementById("drawing"); var c = cnv.getContext('2d'); var image = new Image(); image.src = 'images/spaceship.png'; var imgWidth = image.width; var imgHeight = image.height; var i=0; function animate() { c.clearRect(0,0,640,480); c.save(); c.translate(-(imgWidth/2)+i,200); c.rotate(i * Math.PI/180); c.translate(-(imgWidth/2),-(imgHeight/2)); c.drawImage(image, 0, 0); c.restore(); (i==640+imgWidth) ? i=0: i+=2; }; setInterval(animate, 1); I think my problem is I'm not understanding the translate() method properly. Is this the correct way to do it or am I competely way off?

  • Hide table row based on content of table cell

    - by timkl
    I want to make some jQuery that shows some table rows and hides others based on the content of the first table cell in each row. When I click a list item I want jQuery to check if the first letter of the item matches the first letter in any table cell in my markup, if so the parent table row should be shown and other rows should be hidden. This is my markup: <ul> <li>A</li> <li>B</li> <li>G</li> </ul> <table> <tr> <td>Alpha1</td> <td>Some content</td> </tr> <tr> <td>Alpha2</td> <td>Some content</td> </tr> <tr> <td>Alpha3</td> <td>Some content</td> </tr> <tr> <td>Beta1</td> <td>Some content</td> </tr> <tr> <td>Beta2</td> <td>Some content</td> </tr> <tr> <td>Beta3</td> <td>Some content</td> </tr> <tr> <td>Gamma1</td> <td>Some content</td> </tr> <tr> <td>Gamma2</td> <td>Some content</td> </tr> <tr> <td>Gamma3</td> <td>Some content</td> </tr> </table> So if I press "A" this is what is rendered in the browser: <ul> <li>A</li> <li>B</li> <li>G</li> </ul> <table> <tr> <td>Alpha1</td> <td>Some content</td> </tr> <tr> <td>Alpha2</td> <td>Some content</td> </tr> <tr> <td>Alpha3</td> <td>Some content</td> </tr> </table> I'm really new to jQuery so any hint on how to go about a problem like this would be appreciated :)

  • Uncaught TypeError: Cannot read property 'length' of undefined

    - by AnApprentice
    I'm working to built a contact list that is grouped by the first letter of the contact's last name. After a succesfull ajax request, the contact is pushed to addContact: Ajax success: ko.utils.arrayForEach(dataJS.contactList, function(c) { contactsModel.addContact(c); }); contactsModel.addContact: //add a contact in the right spot under the right letter contactsModel.addContact = function(newContact) { //grab first character var firstLetter = (newContact.lname || "").charAt(0).toUpperCase(); //if it is a number use # if (!isNaN(firstLetter)) { firstLetter = "#"; } //do we already have entries for this letter if (!this.letterIndex[firstLetter]) { //new object to track this letter's contacts var letterContacts = { letter: firstLetter, contacts: ko.observableArray([]) }; this.letterIndex[firstLetter] = letterContacts; //easy access to it //put the numbers at the end if (firstLetter === "#") { this.contactsByLetter.push(letterContacts); } else { //add the letter in the right spot for (var i = 0, lettersLength = this.contactsByLetter().length; i < lettersLength; i++) { var letter = this.contactsByLetter()[i].letter; if (letter === "#" || firstLetter < letter) { break; } } this.contactsByLetter.splice(i, 0, letterContacts); } } var contacts = this.letterIndex[firstLetter].contacts; //now we have a letter to add our contact to, but need to add it in the right spot var newContactName = newContact.lname + " " + newContact.fname; for (var j = 0, contactsLength = contacts().length; j < contactsLength; j++) { var contactName = contacts()[j].lName + " " + contacts()[j].fName; if (newContactName < contactName) { break; } } //add the contact at the right index contacts.splice(j, 0, newContact); }.bind(contactsModel); The contacts json object from the server looks like this: { "total_pages": 10, "page": page, "contactList": [{ "photo": "http://homepage.mac.com/millhouse/Family%20Tree/images/PersonListIcon.png", "lname": "Bond", "id": 241, "fname": "James", "email": "[email protected]"}, While this works in jsfiddle, when I try it locally, I get the following error during the first push to addContact: Uncaught TypeError: Cannot read property 'length' of undefined jQuery.jQuery.extend._Deferred.deferred.resolveWithjquery-1.5.1.js:869 donejquery-1.5.1.js:6591 jQuery.ajaxTransport.send.callbackjquery-1.5.1.js:7382 Ideas?

  • How can I convert seconds to minutes in jQuery while updating an element with the current time?

    - by pghtech
    So I see a number of ways to display allot of seconds in a (static) hr/min/sec. However, I am trying to produce a visual count down timer: $('#someelement').html(minCounter + ' minutes ' + ((secCounter == 0) ? '' : (secCounter + ' seconds'))); My counter is reduced inside a SetInterval that triggers ever 1 second: //....... var counter = redirectTimer; jQuery('#WarningDialogMsg').html(minCounter + ' minutes ' + ((secCounter == 0) ? '' : (secCounter + ' seconds'))); //........ SetInternval( function() { counter -= 1; secCounter = Math.floor(counter % 60); minCounter = Math.floor(counter / 60); //....... $('#someelement').html(minCounter + ' minutes ' + ((secCounter == 0) ? '' : (secCounter + ' seconds'))); }, 1000) It is a two minute counter but I don't want to display 120 seconds. I want to display 1 : 59 (and counting down). I have managed to get it to work using the above, but my main question is: is there a more elegant way to accomplish the above? (note: I am redirecting once "counter == 0").

  • Canvas element covering the entire screen?

    - by Stefan Kendall
    I'm trying to use <canvas> in iPhone Safari, and if I place the element in the body, there are unused pixels to the left and top of the element. I tried specifying margin:0;padding:0 with CSS to no avail. What's going on here? <html> <head> $(document).ready(function() { $('#screen').attr("height", $(window).height() ); $('#screen').attr("width", $(window).width() ); //prevent scrolling $(document).bind('touchstart touchmove', function(e) { e.preventDefault(); }); }); </script> </head> <body> <canvas id = "screen"> </canvas> </body> </html>

  • Why is window not identical to window.self in Internet Explorer?

    - by Jim Puls
    There's a convoluted backstory involving how I came across this, but why is the self property not exactly equal to the window itself? In Safari and Firefox and friends, the results are as I'd expect: > window == window.self true > window === window.self true The same isn't true in Internet Explorer, though: >> window == window.self true >> window === window.self false Can anybody account for the inconsistency? To exactly what is the self property of the window object pointing? It casts to something with equality, which is even more vexing.

  • How to select the first property with unknown name from JSON and how to select first item from array

    - by Oscar Godson
    I actually have two questions, both are probably simple, but for some odd reason I cant figure it out... I've worked with JSON 100s of times before too! but here is the JSON in question: {"69256":{"streaminfo":{"stream_ID":"1025","sourceowner_ID":"2","sourceowner_avatar":"http:\/\/content.nozzlmedia.com\/images\/sourceowner_avatar2.jpg","sourceownertype_ID":"1","stream_name":"Twitter","streamtype":"Social media","appsarray":[]},"item":{"headline":"Charboy","main_image":"http:\/\/content.nozzlmedia.com\/images\/author_avatar173212.jpg","summary":"ate a tomato and avocado for dinner...","nozzl_captured":"2010-05-12 23:02:12","geoarray":[{"state":"OR","county":"Multnomah","city":"Portland","neighborhood":"Downtown","zip":"97205","street":"462 SW 11th Ave","latitude":"45.5219","longitude":"-122.682"}],"full_content":"ate a tomato and avocado for dinner tonight. such tasty foods. just enjoyable.","body_text":"ate a tomato and avocado for dinner tonight. such tasty foods. just enjoyable.","author_name":"Charboy","author_avatar":"http:\/\/content.nozzlmedia.com\/images\/author_avatar173212.jpg","fulltext_url":"http:\/\/twitter.com\/charboy\/statuses\/13889868936","leftovers":{"twitter_id":"tag:search.twitter.com,2005:13889868936","date":"2010-05-13T02:59:59Z","location":"iPhone: 45.521866,-122.682262"},"wordarray":{"0":"ate","1":"tomato","2":"avocado","3":"dinner","4":"tonight","5":"tasty","6":"foods","7":"just","8":"enjoyable","9":"Charboy","11":"Twitter","13":"state:OR","14":"county:Multnomah, OR","15":"city:Portland, OR","16":"neighborhood:Downtown","17":"zip:97205"}}}} Question 1: How do I loop through each item (69256) when the number is random? e.g. item 1 is 123, item2 is 646? Like, for example, a normal JSON feed would have something like: {'item':{'blah':'lorem'},'item':{'blah':'ipsum'}} the JS would be like console.log(item.blah) to return lorem then ipsum in a loop How do I do it when i dont know the first item of the object? Question 2: How do I select items from the geoarray object? I tried: json.test.item.geoarray.latitude and json.test.item.geoarray['latitude']

  • How can I alter anythingSlider so that it disables the next / previous buttons when only 1 <li> in t

    - by madphill
    I have a page with multiple instances of anythingSlider on it and I'm using PHP to dynamically load pages that swap out the content in them. Reference: http://ceedcreative.com/CEED_2.0/ I would like to edit the anythingSlider to disable the previous / next buttons if the UL it's displaying only has one LI within it. In other words, no buttons, just a clean div that's the same heigh and width (no scrolling) if there's only one image.

  • looking for overview of readystate and browsers

    - by Matt
    I'm finding a lot of problems with trying to determine readyState between IE8, FF3, and Chrome. so far this is what I find: Chrome, FF do not fire an event for .onReadyStateChanged Chrome, FF support .onLoad IE8 supports .onReadyStateChanged, but does not support .onLoad IE8 has also returned loaded, and complete. Mostly it states loaded, but every now and then it spits out complete. Can anyone point me to a chart or overview of browsers and the way they handle readyStates?

    I'm having trouble using innerHTML with my radio type button. <table align="center"> <div class='main'> <span id="js" class='info'> <label><input type="radio" name="js" value="0" size="<?php echo $row['size']; ?>" onclick="js(this.value, this.size);" /><img src="arrowup.png"/></label> <br /> <label><input type="radio" name="js" value="1" size="<?php echo $row['size']; ?>" onclick="js(this.value, this.size);" /><img src="arrowdown.png"/></label> </span> </div> </table> My .js looks like this: var xmlhttp; function getVote(a,b) { xmlhttp=GetXmlHttpObject(); if (xmlhttp==null) { alert ("Browser does not support HTTP Request"); return; } var url="js.php"; url=url+"?js="+a; url=url+"&id="+b; url=url+"&sid="+Math.random(); xmlhttp.onreadystatechange=stateChanged; xmlhttp.open("GET",url,true); xmlhttp.send(null); } function stateChanged() { if (xmlhttp.readyState==4) { document.getElementById("js").innerHTML=xmlhttp.responseText; } } function GetXmlHttpObject() { var objXMLHttp=null; if (window.XMLHttpRequest) { objXMLHttp=new XMLHttpRequest(); } else if (window.ActiveXObject) { objXMLHttp=new ActiveXObject("Microsoft.XMLHTTP"); } return objXMLHttp; } This doesn't work in IE only! Any help?

  • jQuery AJAX request (Rails 3) gets redirected and returns empty message body!

    - by elsurudo
    I'm trying to do a manual jQuery AJAX request the following way: $("#user_plan_id").change(function() { $("#plan_container").load('/plans/' + this.value); }); I have the "rails.js" file included in my header, and a "<%= csrf_meta_tag %". I see from my log that the request IS getting to the server (although without the authenticity token... does rails.js even do this?), but the response is a 302 (Found) rather than 200, and no data actually gets rendered. Any ideas? Edit: I now see that the first request redirects, and the proper partial gets rendered on the redirect. However, the 2nd response's body (on the client-side) is still empty. I'm guessing jQuery uses the first response and doesn't have a listener set up for the redirect. How do I get around this? Also, another note: the page doing the requesting is an HTTPS page. Here is what my log says: Started GET "/plans/221168073" for 127.0.0.1 at Tue Jun 15 01:24:06 -0400 2010 Processing by PlansController#show as HTML Parameters: {"id"=>"221168073"} DEPRECATION WARNING: Using #request_uri is deprecated. Use fullpath instead. (called from ensure_proper_protocol at /Users/ernestsurudo/Sites/vidfolia/vendor/plugins/ssl_requirement/lib/ssl_requirement.rb:57) Redirected to http://vidfolia.com/plans/221168073 Completed 302 Found in 1ms Perhaps it has something to do with the deprecation warning?

  • Any good jQuery plugins to awesomify my pagination?

    - by marcgg
    I have a basic pagination system that looks something like that: First | < Previous | 1, 2, [3], 4, 5 ... 100, 101, 102 | Next > | Last Nothing fancy really. I am looking at various plugins to improve the way the user would browse this, but so far I haven't found anything really new or interesting except: http://tympanus.net/jPaginate/ : interesting way of browsing between pages but still very classical in the realization http://cpojer.net/Scripts/Pagination/ : totally new way of doing pagination, but the implementation isn't perfect and it's not really usable. Do you guys have ideas on how I could improve the way my users browse through navigation? Are there any good jQuery plugins out there already doing that?

  • jQuery photo carousel (that looks like a real carousel)?

    - by kastru
    I am on the lookout for a jQuery photo carousel that can display 3 images at a time, and circle through x amount of photos (and when reaching the last, starting with the first photo again). I made a quick mock-up of what i am looking fore - see it here. So there is 3 photos vissible, the middle one beeing the 'main' one and a bit bigger than the previous and next (left and right). Upon clicking the next/previous arrows the next or previous photo slides into the middle and thereby becomes the main photo. Any ideas to where i can find such a jQuery plugin/script?
