• jQuery selector not selecting

  - by Paul Nathan

  I am unable to get this event to fire: $("#about").click(function() { //I have put alert("foo") here, won't fire $("#about_stuff").toggle(); }); snip <li ><a href="#a" id="about">About</a> I've tested the toggle line in Firebug and it successfully works - I am at my wits end, I've checked it against multiple examples and it persistently refuses to work.

• Javascript/jQuery: remove shape/path from canvas

  - by bobsoap

  I can't seem to find the function to remove a shape or path from the canvas after it has been created. So I'm creating a bezier curve between 2 points with beginPath(); bezierCurveTo(); stroke(); closePath(); . How can I remove this from the canvas once it's been created? I need to be able to call the remove function via toggle() and blur(). I'm sure something exists for this... Thanks in advance for any help!

This counter now has to be printed on the relative "li" "span" 3 level before. So I have the number of the element with the "new" class. The js snippet is this $("#fileTreeInviati .php-file-tree .pft-directory li").each(function(){ $(this).children("a").each(function(i,e){ if ($(e).hasClass("new")){ cont++; console.log($(e).text()); $(this).parent().parent().parent().children("a").children("span").text(cont); } }) cont = 0; }); I think I'm almost there but the counter is always 1. I think there is something mess with .children, maybe it can handle only the first occurrence? Thanks for help

• jQuery: preventdefault does not work

  - by Kent Miller

  I somehow cannot achieve that the a-tag looses its default action when clicking it: <a href="#" class="button dismiss">dismiss</a> $(document).ready(function() { $('.dismiss').click(function(e) { e.preventDefault(); $('#output').empty(); $('#MyUploadForm .button').show(); }); }); When I click the button, the browser window scrolls to the top. What is wrong here?

  I have the following: $(document).ready(function(){ // bind 'myForm' and provide a simple callback function $('#form').ajaxForm(function() { alert("Works!!!"); }); }); The problem is that when I dynamically add the form to the HTML the script is not working. If the form is there from the beginning the form is submitted with Ajax and works as expected. What is the problem here?

• How to slow down Uploadify plugin script voor jQuery

  - by Peter

  Now if that isn't a weird question, I don't know what is. But here is the problem: I have a function in my "onSelect" option that has to collect some data (through AJAX) and I have a function in my "onComplete" option that processes the just uploaded files based on the data "onSelect" collected. However, with very small files, the "onSelect" hasn't finished yet before the upload is complete and the "onComplete" fails because it lacks the necessary data. Bigger files work just fine. So, I'm looking for a way to stall the upload of the file. To let it start only after the function in onSelect completed fetching the necessary data. Any ideas? Here is an example of the function that the onSelect triggers: var foo = new Array(); function checkDB( event, queueID , fileObj ) { $.post( ajax_folder + 'fetchData' , { ref: "someValue" } , function( data ){ foo[ queueID ] = data.result; } , 'json' ); return true; }

• Help with Jquery function

  - by Madhur Ahuja

  Ok, Here is my problem: I have this function in a third party javascript library defined as RedirectLink(a,b,c,d,e) where a,b,c,d,e are strings. I also have a link in my webSite which is again autogenerated (And I can't change it) <a href="javascript: RedirectLink("1", "2", "3" ,"4" ,"5")" id="mylink" > What I need to do is, read this anchor's (mylink) href and I need to call RedirectLink function such as javascript: RedirectLink("1", "2", "3" + param, "4" , "5"). where param will come from query string. The first part is easy, reading the href but how to alter the third parameter ?

• floating a div with jquery/offset - ignores href hashtag

  - by Kevin Crawley

  <script type="text/javascript"> $(document).ready(function () { var top = $('#rt_outer').offset().top - parseFloat($('#rt_outer').css('marginTop').replace(/auto/, 0)); $(window).scroll(function (event) { // what the y position of the scroll is var y = $(this).scrollTop(); // whether that's below the form if (y >= top) { // if so, ad the fixed class $('#rt_outer').addClass('fixed'); } else { // otherwise remove it $('#rt_outer').removeClass('fixed'); } }); }); </script> The problem is fairly straight forward. If I use a header redirect to a new location in the page (say half way down, I jump to #halfway after processing a php script using header("somepage.php#halfway") the div container which is handled by this script won't jump down until the page is scrolled in either direction. I know there is a solution to this, I just don't know what.

• finding links that are hyper-links in jQuery

  - by Jacob Lowe

  Im trying to take a link either when clicked or hover over be able to grab the attribute href and tell if its a hyper-link or not. Also i want it to be able to tell me if its a hyper-link to my own site. Plus various other filters. The main purpose for this is so that when a internal link is clicked it will tell ajax to grab the content, alot of my links are generated (via wordpress)so I can't modify them too much. Another purpose for this is so i can also make all external links open on a new window. I have a solution that works on a simple test page but when i put into a working page it breaks. I know i am probably making this harder then it should be. Here is my code $(function(){ $('a').live('click', function(){ var x = $(this).attr('href'); $(this).parent('div').append('<div id="test">' + x +'</div>'); $('#test:contains("http")').css('color', 'red'); $('#test:contains("sitename")').css('color', 'black'); $('#test:contains("admin")').css('color', 'red'); if($('#test').css('color') == 'red'){ alert('external link'); $('#test').remove(); return true; }else{ alert('external link'); $('#test').remove(); return false; } }); }); thanks for you help

• jQuery UI - Accordion Display issues

  - by Dave Kiss

  My accordion is working properly, but I'm having a few CSS and JS issues that are prohibiting it from displaying correctly. http://jsfiddle.net/frEWQ/ The JS is applying .ui-corners-all to the H3 before the "kwick" div below it has finished collapsing, giving an odd cut-off border during the animation The margin-bottom applied to the "kwick" div to give spacing between each tab disappears when the tab is set to display:none, getting rid of the spacing... but I can't apply the margin-bottom to the header because it disconnects the header from the "kwick" div below it. Any suggestions? Modification to the JS/CSS? Thanks
