  • Why does Google's Closure Compiler leave a few unnecessary spaces or line breaks?

    - by Bungle
    I've noticed that every time I use Google's Closure Compiler Service, it leaves a few unnecessary spaces in the compiled code presented on the right-hand side of the page. These correspond to line breaks in the hosted version of the compiled code. For example (note the line breaks, each of which seems unnecessary): http://troy.onespot.com/static/stack_overflow/closure_spaces.js To date, I've just been removing them manually, but I'm curious why they're there. Is it to limit the line length of the hosted version of the code to make it more readable? Could the compiler be smart enough to leave or insert those intentionally to maximize GZIP compression efforts? I know that they have a trivial effect on the file size, but with so much effort going into minifying every last byte in the source script, it's counterintuitive why they're there.

    - by gowri

  • Firefox extension: how to read a cookie name and value on the current page

    - by encryptor
    My extension works on an application, which requires user login. Once the user has logged in, I need to read the cookies and use them in my XMLHttpRequests. So initially I need to check if the cookie is set, if not, I direct the user to the login page. Once logged in, I need to read the cookies and send it as part of my further requests. How do I read cookies from a XMLHttpRequest or otherwise (if we don't even know the name of the cookie) There is to function as getRequestHeader.. but what I need is something like that.

  • Change value of jquery variable based on a select box

    - by Nikos
    I have a jquery datepicker script and what I want to do is to change "minDate: 10" value by a select box. $(function() { $('#hotel').change(function() { // assign the value to a variable, so you can test to see if it is working var selectVal = $('#hotel :selected').val(); if( selectVal == "hotel_c" ) { var date = 10; } if( selectVal == "hotel_a" ) { var date = 15; } if( selectVal == "hotel_b" ) { var date = 6; } }); var dates = $('#from, #to').datepicker({ defaultDate: "+1w", changeMonth: true, dateFormat: 'yy-m-d', minDate: 10, numberOfMonths: 3, onSelect: function(selectedDate) { var option = this.id == "from" ? "minDate" : "maxDate"; var instance = $(this).data("datepicker"); var date = $.datepicker.parseDate(instance.settings.dateFormat || $.datepicker._defaults.dateFormat, selectedDate, instance.settings); dates.not(this).datepicker("option", option, date); } }); });

  • jQuery.ajax checking if there is already another xhr

    - by digitalFresh
    I have a page when, if the user is near the bottom of the page, loads the next page. I just recently switched it to jQuery, and now use the jQuery.ajax() function to get the data. However, now i cannot check if the xhr is already loading, making the page load multiple xhrs when the user near the bottom. My listener is: $(document).scroll(function () { if(/* scrollbar is near bottom */) loadxhr(dat++); //function that calls jQuery.ajax() } }); Basically, can you track the readyState of the call in a global scope?

  • Parallel scroll textarea and webpage with jquery

    - by Roger Rogers
    This is both a conceptual and how-to question: In wiki formatting, or non WYSIWYG editor scenarios, you typically have a textarea for content entry and then an ancillary preview pane to show results, just like StackOverflow. This works fairly well, except with larger amounts of text, such as full page wikis, etc. I have a concept that I'd like critical feedback/advice on: Envision a two pane layout, with the preview content on the left side, taking up ~ 2/3 of the page, and the textarea on the right side, taking up ~ 1/3 of the page. The textarea would float, to remain in view, even if the user scrolls the browser window. Furthermore, if the user scrolls the textarea content, supposing it has exceeded the textarea's frame size, the page would scroll so that the content presently showing in the textarea syncs/is parallel with the content showing in the browser window. I'm imagining a wiki scenario, where going back and forth between markup and preview is frustrating. I'm curious what others think; is there anything out there like this? Any suggestions on how to attack this functionality (ideally using jquery)? Thanks

  • jQuery Script works in all browsers but Chrome

    - by Moak
    This site has a script that works in all browsers i tested but Chrome, which i think is strange because it is usually IE that acts up. The error console says Uncaught TypeError: Cannot call method 'toLowerCase' of undefined Uncaught TypeError: Object #<an Object> has no method 'set' however i don't know what to do with this information. Any ideas?

  • Writing UTF8 text to file

    - by sonofdelphi
    I am using the following function to save text to a file (on IE-8 w/ActiveX). function saveFile(strFullPath, strContent) { var fso = new ActiveXObject( "Scripting.FileSystemObject" ); var flOutput = fso.CreateTextFile( strFullPath, true ); //true for overwrite flOutput.Write( strContent ); flOutput.Close(); } The code works fine if the text is fully Latin-9 but when the text contains even a single UTF-8 encoded character, the write fails. The ActiveX FileSystemObject does not support UTF-8, it seems. I tried UTF-16 encoding the text first but the result was garbled. What is a workaround?

  • Is using iframes to improve page performance an acceptable approach?

    - by Denis Hoctor
    Hi all, I have a complex page that has several user controls like galleries, maps, ads etc. I've tried optimising them by ensuring full separation of html/css/js, placing js at the bottom of the page and trying to ensure I have well written code in all 3 but alas I still have a slow page. It's not really noticeable to a modern browser but can see the stats and IE6/7. So I'm now looking to do what we've done previously for Adtech flash crap - an iframe. Apart from the SEO impact which I'm not worried about in the case of these controls, what do people think of this as an approach? PROS and CONS please. Thanks, Denis

  • fetching a url using $.getJSON and parsing it correctly

    - by sofia
    This is probably really stupid but i can't find the problem with my code. It fetches a url that returns json and the function is then supposed to return a string: function getit() { var ws_url = 'example.com/test.js'; var user = false; $.getJSON(ws_url, function(data) { alert('user '+data.user);//shows john user = data.user || false; } ); return user;//should return john but returns false } test.js will have something like this: {"id":"12","username":"ses","user":"john","error":""} or like this: {"error":"123"} I also tried if(data.user){}else{} but it didn't work either.. So what am i missing? Thanks :)

  • How to encorporate encyption to FlexPaper

    - by Jonathan
    Is it possible to configure the FlexPaper reader to un-encrypt password-protected pdfs or swfs? Here is the use-case: User uploads a pdf My server would then convert the pdf to swf via pdf2swf Then somehow encrypt the swf with a password (not sure best way to do this) Then the FlexPaper would be able to un-encrypt the swf and display it What I am trying to avoid is the caching of readable swf in the browser's cache. Any ideas on the best way to achieve this? I know, even with this it will not be a fully secure solution, but certainly helps. Note: I am running this on Linux and OS X and using Rails. Thanks!

  • How change the videos max of page with jQuery ?

    - by Shady
    I have one website here that contains videos to see, like youtube, and the videos are divided in pages, and in the source of this page I got this part of the source: <input type="hidden" value="12" id="vid_count"> <input type="hidden" value="422" id="vid_max"> <input type="hidden" value="12" id="vids_per_page"> The site contains 422 videos with 36 pages, 12 videos per page I need to show all videos in only one page... I've already tried document.getElementById("vids_per_page").setAttribute("value", "500"); but this doesn't work... How can I do it? (via greasemonkey) any additional info?

  • jQuery performance

    - by jAndy
    Hi Folks, imagine you have to do DOM manipulation like a lot (in my case, it's kind of a dynamic list). Look at this example: var $buffer = $('<ul/>', { 'class': '.custom-example', 'css': { 'position': 'absolute', 'top': '500px' } }); $.each(pages[pindex], function(i, v){ $buffer.append(v); }); $buffer.insertAfter($root); "pages" is an array which holds LI elements as jQuery object. "$root" is an UL element What happens after this code is, both UL's are animated (scrolling) and finally, within the callback of animate this code is executed: $root.detach(); $root = $buffer; $root.css('top', '0px'); $buffer = null; This works very well, the only thing I'm pi**ed off is the performance. I do cache all DOM elements I'm laying a hand on. Without looking too deep into jQuery's source code, is there a chance that my performance issues are located there? Does jQuery use DocumentFragments to append things? If you create a new DOM element with var new = $('<div/>') it is only stored in memory at this point isnt it?

  • Rebinding jQuery qtip tooltip on images in bxcarousel

    - by skerit
    I'm using bxcarousel to show a bunch of images. Each image has a tooltip, which I display using qtip. This works fine for the first round, but when the images come round a second time the tooltips don't show anymore (because bxcarousel removes an element that slides out and puts it back at the end) An example of the carousel can be found here: http://www.kipdola.be/carousel/carousel.html This is the code used to bind the events (maybe it needs a "live" function somewhere?) // Create the tooltips only on document load $(document).ready(function() { // Use the each() method to gain access to each elements attributes $('#shopcarousel a[rel]').each(function() { $(this).qtip(

  • How do you optimize stunicholls' "Professional dropdown #2" with jquery?

    - by geff_chang
    Link to menu: Professional dropdown #2 I was wondering if these posts Suckerfish meets jQuery or Son of Suckerfish dropdowns in jQuery could optimize the menu above. I need the menu to be optimized for IE6, because when I use the menu as it is, the menu hangs after I click on a menu item that loads a page with heavy processing. It takes too long for the menu to be enabled again. Any ideas?

  • try/catch: errors or exceptions?

    - by Josh
    OK. I may be splitting hairs here, but my code isn't consistent and I'd like to make it so. But before I do, I want to make sure I'm going the right way. In practice this doesn't matter, but this has been bothering me for a while so I figured I'd ask my peers... Every time I use a try... catch statement, in the catch block I always log a message to my internal console. However my log messages are not consistent. They either look like: catch(err) { DFTools.console.log("someMethod caught an error: ",err.message); ... or: catch(ex) { DFTools.console.log("someMethod caught an exception: ",ex.message); ... Obviously the code functions properly either way but it's starting to bother me that I sometimes refer to "errors" and sometimes to "exceptions". Like I said, maybe I'm splitting hairs but which is the proper terminology? "Exception", or "Error"?

  • Make a div fall off the page

    - by Daniel Hertz
    Hey, So I have been playing with jQuery for a good time now and I'm trying to get an effect to work properly. I have a main square div in the middle of the page and when someone clicks a link I want the box to look like its falling off the page and disappear, revealing a new page behind it. I'v been playing with the easing plugin but I can seem to get what I want to work. Basically I have the div's top margin or just top distance increased to a large number. However, this just makes the div fall but it also expands my page and its just much lower on the page. I basically want the div to fall out of site and not change the dimensions of the site. Anyone know how to do that? Thanks! Danny

Part 2: How do i convert that object back to a query string? it would probably be trivial code that i can write.
