  • GZipping CSS and JS files

    - by Ryan Giglio
    I'm using YSlow to improve the speed of my site, and I'm having trouble with the "compress components with gzip" grade. I have this in my .htaccess file: SetOutputFilter DEFLATE AddOutputFilterByType DEFLATE text/html text/plain text/xml text/css application/x-javascript But YSlow is saying There are 4 plain text components that should be sent compressed * http://crewinyourcode.com/css/reset.css * http://crewinyourcode.com/css/inner-pages/index.css * http://crewinyourcode.com/script/css/jquery-ui-1.8.custom.css * http://crewinyourcode.com/js/inner-pages/index.js How can I gzip the css and js files? Also...I don't have access to the httpd.conf file.

  • qmake -project command gives QFileInfo warning in Qt 4.6

    - by Pilgrim
    I've upgraded to Qt 4.6 on my Mac (OS 10.5). When I go to a project directory and run: qmake -project Qt returns this warning (although it doesn't say it's a warning, I assume it is since the .pro file gets created anyway): QFileInfo::absolutePath: Constructed with empty filename I did a completely new install thinking that the "upgrade" wasn't clean for whatever reason, it still does it. Any ideas as to why? Here is an example .pro that results from above command: ###################################################################### # Automatically generated by qmake (2.01a) Mon Apr 19 07:39:53 2010 ###################################################################### TEMPLATE = app TARGET = DEPENDPATH += . INCLUDEPATH += . # Input HEADERS += mainwindow.h SOURCES += main.cpp mainwindow.cpp RESOURCES += jquery.qrc

  • Google App Engine: lose CSS on deployment?

    - by Rosarch
    I have a Google App Engine app that works fine on the dev server. However, when I upload it, the CSS is gone. The scripts are still there, however. From app.yaml: - url: /scripts static_dir: Static/Scripts - url: /styles static_dir: Static/styles From the base template: <head> <meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1" /> <script type="text/javascript" src="./scripts/JQuery.js"></script> <script type="text/javascript" src="./scripts/sprintf.js"></script> <link rel="stylesheet" href="./styles/style.css" type="text/css" media="screen" /> </head> What could be causing this? Am I doing something wrong?

  • Maintaining the query string in ASP.Net MVC

    - by Mantorok
    Hi all Just beginning my journey in ASP.Net MVC and I have a query about something before I dig myself in too deep. I have a table, which is paged, and I have 2 controls above the table: Dropdown that defines order of the results and apply button next to it Textbox that defines a filter and apply button next to it What I need to achieve is that if the user changes the order or adds a filter I fire of an AJAX call to my action like such: /Membership/Users?sort=value&filter=value&page=pagenumber. So my controller action is: // GET Membership/Users?sort=&filter=&page= public ActionResult Users(string sort, string filter, string page) So I have 3 questions: Is this the correct approach? What would be the best way to ensure that the query string is maintained, bearing in mind that the action will nearly always be called by Jquery/Ajax functions? If I wanted to link directly to this action passing the arguments would I need to hard-code the querystring? Thanks

  • javascript table - update on data request

    - by flyingcrab
    Hi, I am trying to update a table based on a json request. The first update / draw works fine - but any subsequent changes to the variables (the start and end date) do not show up - even though the json pulled from the server seems to be correct (according to firebug). AFAIK the code below should re-initialize everything - no sure what is going on (I'm using the Google vizulization api)? function handleQueryResponse(response) { if (response.isError()) { //alert('Error in query: ' + response.getMessage() + ' ' + response.getDetailedMessage()); return; } visualization = new google.visualization.Table(document.getElementById('visualization')); visualization.draw(response.getDataTable(), null); } One more thing: I'm working on a page that displays textbased tables and currently trying to decide between the google table (viz api) and a jQuery alternative I came across jqGrid any good ones I am missing?

  • Benefit of outputting JSON as opposed to plain HTML

    - by Franco
    Hey guys, Just wondering which is best here. I want to output data from a table in my DB then put a lot of this data into a html table on the fly on my page. Im working with Java on the server side. Basically I pull the results form the DB and have the raw data..just what next? There is a chance I may want to take data from multiple tables in order to combine it into one table for my site. I retrieve the results of the query from the DB, now do i create a text from it in the form of json which i can parse as json using jquery upon the return of the object to my browser?(kind of a sub question of this question: Is just using a stringbuilder the correct way to make a json object to output?) Or.. Should i build the HTML as a string and output that to the browser instead? Which is better and why? Thanks in advance!

  • Specify only the second parameter in a javascript function

    - by Ben McCormack
    The spec for the jQuery ajax.error function is: error(XMLHttpRequest, textStatus, errorThrown)Function I'm trying to catch the error and display the textStatus, but I can't figure out how to specify only the textStatus without having to put in a variable name for XMLHttpRequest and errorThrown. My code currently looks like this: $.ajax({ type: "POST", contentType: "application/json; charset=utf-8", url: hbAddressValidation.webServiceUrl, data: this.jsonRequest, dataType: "json", timeout: 5, success: function (msgd) { //... }, error: function (a,textStatus,b) { $("#txtAjaxError").val("There was an error in the AJAX call: " + textStatus); } }); You can see in my code that I'm putting variables a and b as placeholders for the first and last variables in the error function. I know that in my success function, I'm only providing one parameter and it works fine, but in that case data is the first parameter. In the case of error, textStatus is the second parameter, but that's the only one I want to specify. Is this possible?

  • replace values in form.data when form fails validation

    - by John
    Hi I have a form field which requires a json object as its value when it is rendered. When the form is submitted it returns a comma seperated string of ids as its value (not a json string). however if the form does not validate i want to turn this string of ids back into a json string so it will display properly (is uses jquery to render the json object correctly). how would i do this? I was thinking of overwriting the form.clean method but when I tried to change self.data['fieldname'] I got the error 'This QueryDict instance is immutable' and when i tried to change self.cleaned_data['fieldname'] it didn't make a difference to the value of the field. Thanks

  • building a website

    - by Ant
    Not sure if this is the right place to post this, or if it should be under programmers.stackexchange... Anywho, a couple of my friends run a business and they asked me to build them a public website. It will only be used for information about the company with soe pictures. No transactions will be involved. Right now I work for a company where I build internal websites, and do alot of backend programming in C#. I understand html, css, jquery, etc. so I feel like I am completely capable of building a website for them. However, I do not know all the basic knowledge to building one. For example, where should we host the files, what type of security issues do I need to be aware of, what's the best software to use for developing websites (I use visual studio at work), where can I find some design techniques, etc. Any help is appreciated.

  • Javascript Canvas Element - Array Of Images

    - by Ben Shelock
    I'm just learning JS, trying to do things without jQuery, and I want to make something similar to this however I want to use an array of images instead of just the one. My image array is formed like this var image_array = new Array() image_array[0] = "image1.jpg" image_array[1] = "image2.jpg" And the canvas element is written like this. (Pretty much entirely taken from the Mozilla site) function draw() { var ctx = document.getElementById('canvas').getContext('2d'); var img = new Image(); img.src = 'sample.png'; img.onload = function(){ for (i=0;i<5;i++){ for (j=0;j<9;j++){ ctx.drawImage(img,j*126,i*126,126,126); } } } } It uses the image "sample.png" in that code but I want to change it to display an image from the array. Displaying a different one each time it loops. Apoligies if I've not explained this well.

    - by brz dot net
    What are the pros and cons of the following 2 cases: Case I: Traditional way: Add service reference in project. Create object and Get data from service on server side and bind to asp.net grid. Case II: Update Service for JSON behavior. Add service reference in project. Call service from javascript to get data. Bind data to jquery grid. Which one is the best approach and why?(Not developer point of view) If there is another approach which is more optimized, please explain it.

  • Google Translate set default language

    - by tdurham
    Maybe this has an obvious solution that I'm overlooking, but I can't seem to find the correct parameter to put in to make this happen. Using the Google Translate widget on a site, I need to set the default language that the user sees when entering the site, even though the site is english. function googleTranslateElementInit() { new google.translate.TranslateElement({ pageLanguage: 'en' }, 'google_translate_element'); } I've tried adding: defaultLanguage: 'fr' and tried: targetLanguage: 'fr' I did find some nice jQuery solutions, but didn't want to bypass this if it was an easy fix. Thanks in advance.

  • String.Format in javascript?

    - by chobo2
    Hi this is driving me nuts. I believe I asked this exact same question but I can't find it anymore(I used stackoverflow search, google search, manually searched my posts, searched my code). I wanted something that would be like the C# String.Format where you could do something like string format = String.Format("Hi {0}",name); just for javascript of course and one person gave me a simple answer it was not like a jquery plugin or anything but I think you made some json thing or something and it worked and was simple to use. I for the life of me can't find this post.

  • What is the easiest way to send a Javascript array via JSON to PHP?

    - by dscher
    I have a few arrays that I want to send to process with PHP. Using json2.js I will stringify the arrays like so: var JSONlinks = JSON.stringify(link_array); var JSONnotes = JSON.stringify(note_array); but then I'm confused. Do I need to use a XMLHttpRequest object? Is there another way? If that is the simplest way, could someone please just share the most basic instance of the code needed in order to send to PHP where I can then use JSON decode? I think it might help others in the future really. I'm currently using Jquery and I know there are many options out there for frameworks and each one may or may not make this process any easier. If you're using a framework in your reply please mention why you'd choose that framework rather than just javascript.

  • Unneded number combination after replacing a number in a string.

    - by ne5tebiu
    I get an unneeded number combination. 3, 4, 5, 6, 7, 8, 901234567890123456789, 30 Should be: 3, 4, 5, 6, 7, 8, 9, 10, 11, 12... (till) 30 Why that happens? The code: <? ob_start(); $id=$_GET['id']; if (!empty($id)){ $id=str_replace('a9_','', $id); $value=$_COOKIE['NaudingasURL']; $exp = explode(", ", $value); if(in_array($id, $exp)){ $value2=str_replace(', '.$id,"", ', '.$value); $value2=substr($value2, 2, strlen($value2)); echo'r'; } else{ $value2=$value.', '.$id; echo'a'; } setcookie("NaudingasURL", $value2); } ob_end_flush(); ?> I'm calling it with Jquery ajax, but I don't thinks that's the problem.

  • Javascript form validation - multiple form fields larger than 0

    - by calebface
    function negativeValues(){ var myTextField = document.getElementById('digit'); if(myTextField.value < 0) { alert("Unable to submit as one field has a negative value"); return false; } } Above is a Javascript piece of code where every time a field id 'digit' has a value that's less than 0, than an alert box appears either onsubmit or onclick in the submit button. There are about 50 fields in the form that should be considered 'digit' fields where they shouldn't be anything less than 0. What should I change with this Javascript to ensure that all 'digit' like fields have this alert box pop up? I cannot use jquery/mootools for validation - it has to be flat Javascript. Thanks.

  • Tomcat JSP(2.0) Document how to stop automaticly closing empty body tags with /> instead of </tagnam

    - by JOKe
    The question is. If I use JSP Documents (or JSP 2.0) and If I put a TAG without a BODY it is automaticly closed I dont want that. so If I have <div id=....> </div> it is automaticly converted to <div id=.../> How I can stop this ? I am using tomcat is there any configuration about that ? P.S. the reason to want to stop it is because it simple "fuckes" the JQuery stuffs that the designer company are using.

  • Drag and drop an image from desktop to a web text editor (implementation in javascript)

    - by fatmatto
    I tried to write reasonably short title but i failed i guess.. Hi everybody here's what i'm trying to do: I want to implement a web text editor able to recognize when the user drag a image file over it's editing surface and it automa(gically) starts the upload and insert the image near the cursor position. In other words i don't want the user to do the usual "insert-image-browse-ok". Atm i am not very good at javascript ... i know JQuery but i have not a clear idea about how to implement this... i don't know if there's an event handler able to help me in this situation... if not then there should be i think or web apps would miss some kind of interactivity. I've heard miracles about HTML5 could it help me? I've seen such things in Google Wave but that surface doesn't seem to be a form field... google lab's black magic i guess.... Thank you in advance.

  • Backbone.js - Getting JSON back from url

    - by Brian
    While trying to learn Backbone.js, I've been trying to grab the content of a JSON file using the following code: (function($){ var MyModel = Backbone.Model.extend(); var MyCollection = Backbone.Collection.extend({ model : MyModel, url: '/backbone/data.json', parse: function(response) { console.log(response); return response; } }); var stuff = new MyCollection; console.log(stuff.fetch()); console.log(stuff.toJSON()); })(jQuery) 'stuff.fetch()' returns the entire object (with the data I'm after in responseText), 'stuff.toJSON' returns nothing ([]), but the console in the parse method is returning exactly what I want (the json object of my data). I feel like I'm missing something obvious here, but I just can't seem to figure it out why I can't get the right data out. Could someone point me in the right direction or show me what I'm doing wrong here? Am I using a model for the wrong thing?

  • drupal: so many js and css files ?

    - by Patrick
    hi, I've realized I'm loading a lot of resources (24 css and 17 js files) using Drupal. I've several modules installed and they all come with a css and js file. For my website I'm only using 1 additional js plugin (all the other 16 come with Drupal modules). I've not installed useless modules. They are all necessary, and they require js such as swfobject, ajax_views, jquery.media, spamspan, lightbox (modal, video and default js files), etc Same thing with css files: ckeditor, filefield, lightbox, tagadelic, uploadfield, fieldgroup, vews, taxonomy_super_select, html-element, tabs, messages... etc For my website, I only use my theme css zen.css of course. So.. is this normal ? Or I should remove all this stuff? Are drupal websites normally heavy ? thanks

  • Visual Studio 2008 Unresponsive When Opening JavaScript Files

    - by lush
    I'm starting a new ASP.NET project that I'm trying to use some jQuery with, but whenever I try to open .js file (blank or containing a few lines of javascript) in Visual Studio, it often hangs; showing the .js filename in a new tab, but the actual text editor window showing whatever was drawn to the screen before opening the .js file. Eventually, after closing and re-opening, it will open in the text editor, but the font is always something like 10pt Arial. Even after changing this in VS options, the next re-launch of Visual Studio yields the same results. Has anyone else experienced hang, unresponsiveness, wonkiness from Visual Studio with JavaScript files?

  • JS dynamic img change and SEO

    - by Gusepo
    Hi all, I've built a web site using jquery to make nice transitions between content. The code works this way: there are 2 imgs (body and footer) when I click on a link (instead of going to another page) I fade out the 2 imgs and change the src attribute of the 2. When the new imgs are loaded I fade them back in. I'm using SWFaddress to allow user go directly to internal content. Now I'd like to make my content indexed by google and other Search engines, all the text content is inside the imgs, So I've got the text in ALT attribute. My question is: if a dinamically change the imgs ALT attribute using JS, will spiders be able to read it properly? consider that I'm using SWFaddress to create a sitemap.. Thanks
