  • how to use javascript to download a file on Chrome without Chrome auto renaming file to "download"? [duplicate]

    - by user3688566
    This question already has an answer here: Is there any way to specify a suggested filename when using data: URI? 11 answers I use javascript to generate a file and download. It seems that depending on the version of chrome, the download file names can be auto renamed to 'download'. is there a way to avoid it? this is my code: var link = document.createElement("a"); link.setAttribute("href", 'data:application/octet-stream,' + 'file content here'); link.setAttribute("download", 'file1.txt'); link.click(); This is not a duplicated question because i am using the latest chrome and the previously suggested hyperlink is exactly what i am using. I think chrome v34 works fine. but once my chrome autoupdated to v35, it went back to 'download' file name.

  • jQuery: Toggling an image when toggling a DIV

    - by Wanda
    Hey guys, I'm trying to write some jQuery that will toggle DIVs open and closed, and it's working, but I want an arrow that will change to "down" if the DIV is expanded, and "right" if the DIV is collapsed. What I have so far: $('.toggleHead').click(function() { $('#arrow').attr('src', 'images/icons/down.png'); $(this).next().toggle(); return false; }).next().hide(); Where would I put the other $('#arrow').attr('src', 'images/icons/right.png');? Thanks!

  • How come $(this) is undefined after ajax call

    - by JohnnyQ
    I am doing an ajax request when an anchor tag is clicked with an ID set to href. Btw, this anchor tag is dynamically created. <a href="983" class="commentDeleteLink">delete</a> When the anchor tag is clicked the following code is executed: $('.commentDeleteLink').live('click', function(event) { event.preventDefault(); var result = confirm('Proceed?'); if ( result ) { $.ajax({ url: window.config.AJAX_REQUEST, type: "POST", data: { action : 'DELCOMMENT', comment : $('#commentText').val(), comment_id : $(this).attr('href') }, success: function(result) { alert($(this).attr('href')); //$(this).fadeOut(slow); } }); } }); When I tried to display $(this).attr('href') it says it's "undefined". What I really want to do is fadeOut the anchor tag but when I investigated the value of $(this) it is "undefined". What could be wrong with the snippet above?

  • Best way to save info in hash

    - by qwertymk
    I have a webpage that the user inputs data into a textarea and then process and display it with some javascript. For example if the user types: _Hello_ *World* it would do something like: <underline>Hello</underline> <b>World</b> Or something like that, the details aren't important. Now the user can "save" the page to make it something like site.com/page#_Hello_%20*World* and share that link with others. My question is: Is this the best way to do this? Is there a limit on a url that I should be worried about? Should I do something like what jsfiddle does? I would prefer not to as the site would work offline if the full text would be in the hash, and as the nature of the site is to be used offline, the user would have to first cache the jsfiddle-like hash before they could use it. What's the best way to do this?

  • Isotope active class when using select menu

    - by Michael
    I am using Metafizzy's Isotope plugin and have it set up to filter using a select menu as seen here: http://jsfiddle.net/trewknowledge/jJZEN/ $(function() { var $container = $('#container'), $select = $('#filters select'); $container.isotope({ itemSelector: '.item' }); $select.change(function() { var filters = $(this).val(); ; $container.isotope({ filter: filters }); }); });? What I am trying to figure out is how I would add a highlight/active class to the selected elements when the filters variable is already being used.

  • Merging $.get and $.ready

    - by cwolves
    Put simply I have an ajax call that sometimes completes before the page is loaded, so I tried wrapping the callback in $( fn ), but the callback doesn't fire if the page is loaded... Anyone have a good solution to this? $.get( '/foo.json', function( data ){ $( function(){ // won't get here if page ready beats the ajax call // process data $( '.someDiv' ).append( someData ); } ); } ); And yes, I know that if I flipped the order of those it would always work, but then my ajax calls would be needlessly deferred until the document is ready.

  • Is it possible to exclude some elements from parsing when using regular expression and .replace()?

    - by Fletus Mefitis
    <script language="javascript"> $("div.post-content , .parsedsig").each(function(){ if($(this).html().indexOf("[/tabulaScriptum]") != -1) { pattern = /\[tabulaScriptum=(.*?)\]([^\[]*)\[\/tabulaScriptum\]/gi $(this).html($(this).html().replace(pattern, "<div class='tabulaScriptum'><div class='tabulaNomen'>$1</div><div class='tabulaImpleo'>$2</div></div>")) } }); </script> This script is working perfectly, except for one thing... I need not to replace [tabulaScriptum=][/tabulaScriptum] in certain elements. For example, I don't want to replace those "tags" in element that has class .code-box. Is it possible? Clarification: element .code-box is located within .post-content. Clarification #2: this script creates simple division spoiler. .tabulaScriptum is spoier's body, .tabulaNomen is spoiler's name and button which, in turn, reveals(or hides) .tabulaImpleo on click. Reveal\hide script is located in some other place, and I didn't post it here since it doesn't really matter. Clarification #3: http://jsfiddle.net/PRtsw/1/ fiddle.

  • How to get four following text inputs after each checkbox?

    - by Richard Knop
    I am traversing checkboxes like this: $('.day').each(function() { // here I need to get the following 4 text inputs in the HTML // and set some attributes on them }); After every checkbox there are four text input fields (there are also some div, span tags for CSS around them). So inside the loop above I need to get four text input fields that follow the checkbox in the HTML source so I can set some attributes on them. How would I go about that?

  • Checking for length of ul and removing an li element

    - by Legend
    I am trying to remove the last <li> element from a <ul> element only if it exceeds a particular length. For this, I am doing something like this: var selector = "#ulelement" if($(selector).children().length > threshold) { $(selector + " >:last").remove(); } I don't like the fact that I have to use the selector twice. Is there a shorter way to do this? Something like a "remove-if-length-greater-than-threshold" idea. I was thinking that maybe there is a way to do this using the live() function but I have no idea how.

  • removing image tag from memory

    - by Chapsterj
    I have seen some code to check if a background image on a div is loaded. What they are doing is adding a img tag to memory but storing it in a variable and using that to see if the image is loaded with the load event. My question is does the $img tag stay in memory and how would I be able to remove that tag when the load event has been called. var $div = $('div'), bg = $div.css('background-image'); if (bg) { var src = bg.replace(/(^url\()|(\)$|[\"\'])/g, ''), $img = $('<img>').attr('src', src).on('load', function() { // do something, maybe: $div.fadeIn(); }); } }); I got this code above from this post

  • Update (ajax) only part of table without affecting whole table

    - by ile
    <table width="100%" border="0" cellspacing="0" cellpadding="0" class="list"> <tr> <th><a href="#" class="sortby">Full Name</a></th> <th><a href="#" class="sortby">City</a></th> <th><a href="#" class="sortby">Country</a></th> <th><a href="#" class="sortby">Status</a></th> <th><a href="#" class="sortby">Education</a></th> <th><a href="#" class="sortby">Tasks</a></th> </tr> <div class="dynamicData"> <tr> <td>Firstname Lastname</a></td> <td>Los Angeles</td> <td>USA</td> <td>Married</td> <td>High School</td> <td>4</td> </tr> </tr> <tr> <td>Firstname Lastname</a></td> <td>Los Angeles</td> <td>USA</td> <td>Married</td> <td>High School</td> <td>4</td> </tr> </div> </table> The idea is to update table rows when clicking on link with clasl "sortby" which is part of th table tag. I tried inserting div but this doesn't work. Separating this in two tables is not good solution because witdh in both tables cell are not following each other. Any other solution? Thanks

    Hi, I've seen an interesting image hover effect being used a lot lately and was wondering whether anyone has any tips or advice on how best to create this effect? What I'd like to create is a hover effect, so that when you hover over an image, the image fades and a magnifying glass or similar icon fades in. Highlighting the fact that if you click the image, it will enlarge etc. Here is a nice example of the effect: http://themes.mysitemyway.com/infocus/gallery/portfolio/ Any advice or pointers would be greatly appreciated.
