  • getting the names of elements in JS/jQuery

    - by Mala
    I have some checkbox inputs like so: <input type="checkbox" name="1" class="filter"/> <input type="checkbox" name="2" class="filter"/> ...etc... I'm trying to write a function where any time a checkbox is selected, it generates a string with all the names concatenated. Here's what I have so far: $('.filter').click(function(event){ var filters = $('.filter').toArray(); var fstr = ""; for (f in filters) { fstr = fstr+","+f.name; } alert(fstr); }); The names keep coming up as 'undefined', though (i.e. the alert returns ,undefined,undefined,undefined,undefined,undefined,undefined). How do I access the names?

  • javascript, jQuery: how to save values instead of the references

    - by Patrick
    hi, I'm using the following lines to store the location of an object. var lightboxTop = $('#lightbox').css('top'); var lightboxLeft = $('#lightbox').css(' left'); I'm successively moving this object in my element, and I want to restore it previous position with the stored variables. But, I'm afraid javascript is saving the values by reference so I lose the initial positions. Am I correct ? How can I solve this ? thanks

  • IE not showing jquery append() images

    - by Johannes Ruuska
    Ok, so i took John Raasch's slideshow script and modyfied it too dynamicly fetch images from folders on the server through ajax. The slideshow work like a charm in FF and Chrome but IE is not showing the images. And since IE's javascript debugging possibilities is close to none I cant figure out what is crashing. Javascript (indenting got messed up when pasting here but you get the code anyway): function slideSwitch() { var $active = $('#box_bildspel IMG.active'); if ( $active.length == 0 ) $active = $('#box_bildspel IMG:last'); var $next = $active.next().length ? $active.next() : $('#box_bildspel IMG:first'); $active.addClass('last-active'); $next.css({opacity: 0.0}) .addClass('active') .animate({opacity: 1.0}, 1000, function() { $active.removeClass('active last-active'); }); } $(document).ready(function(){ $.get('includes/bildspel.php?page='+page, function(r){ var file = r.split('!'); var path = 'pic/bildspel/'+page+'/'; var data = ''; if(file != null && file != ''){ $.each(file, function(key, value){ if(key == 0) { $('#box_bildspel').append('<img src="'+path+value+'" class="active"></img>'); //console.log(path+value); } else { $('#box_bildspel').append('<img src="'+path+value+'"></img>'); //console.log(path+value); } }); } if(file.length > 1){ $(function() { setInterval( "slideSwitch()", 4000 ); }); } }); }); PHP: <?php function getimgs($page) { $path = '../pic/bildspel/'.$page; $files = ''; if ($handle = opendir($path)) { while (false !== ($file = readdir($handle))) { if ($file !== '.' && $file !== '..') { $files .= $file.'!'; } } closedir($handle); echo substr_replace($files ,"",-1);; } } getimgs($_GET['page']); ?> Tested in IE 7 & 8 Any ideas? I have a deadline on this site for tomorrow (april 23) would appreciate VERY much if someone could figure this on out for me, thanks in advance!

  • JQuery input elements

    - by codeasp
    I need to get all input elements within a div and then attach event handlers, so that whenever values change it updates a hidden field. Children elements within the div might already contain event handlers, if so the attach should chain it. Any help is much appreciated.

  • Can't get jQuery to get focus on cloned input fields

    - by Rebel1Moon
    I have a page that needs to create dynamic form fields as often as the user needs, and I am trying to use Ajax to tie it in to my database for faster form entry and to prevent user typos. So, I have put my Ajax returned data into popup div, the user selects, then the form field is filled in. The problem comes on the cloned fields. They don't seem to want to bring up the popup div when focused. I am thinking it is something to do with when they get created/added to the DOM. Here is my JS that creates the clones: $(document).ready(function() { var regex = /^(.*)(\d)+$/i; var cloneIndex = $(".clonedInput").length; $("button.clone").live("click", function(){ $(this).parents(".clonedInput").clone() .appendTo("#course_container") .attr("id", "clonedInput" + cloneIndex) .find("*").each(function() { var id = this.id || ""; var match = id.match(regex) || []; if (match.length == 3) { this.id = match[1] + (cloneIndex); } }); cloneIndex++; numClones=cloneIndex-1; //alert("numClones "+numClones); }); Here is where I expect to be able to get focus on the correct cloned field and call the popup. The baker_equiv0 id is original code, whereas baker_equiv1 is the first clone. $('#baker_equiv0').focus(function() { \\ THIS CODE WORKS $('.popup').fadeIn(500); $('#results').empty(); // document.enter_data.baker_equiv1.value="test"; THIS LINE WORKS //alert("numClones "+numClones); }); $('#baker_equiv1').focus(function() { // THIS DOESN'T EVER FIRE alert("numClones "+numClones); $('.popup').fadeIn(500); $('#results').empty(); }); Here is the HTML with the form: <label for="baker_equiv" class="">Baker Equivalent: <span class="requiredField">*</span></label> <input type="text" class="cinputsa" name="baker_equiv[]" id="baker_equiv0" size="8" ONKEYUP="get_equiv(this.value);"> If I put this in the HTML code above, it works fine: onfocus="alert(this.id)" I'd also be interested in how to adjust the JS code to work based on the id array created rather than having to copy code for each potential set of fields clones, i.e., baker_equiv[] rather than baker_equiv0, baker_equiv1, etc. Thanks all!

  • Chrome + jQuery hide/show inline

    - by Parhs
    Hello I have these things <ul class="ul_std" style="float:right"> <li class="action_buttons" ><a id="button_deleteNormal" class="button_small button_small_red" >??a??af?</a></li> <li class="action_buttons"><a id="button_editCancel" class="button_small" >?????s? ???p?p???s??</a></li> <li class="action_buttons"><a id="button_editNormal" class="button_small" >???p?p???s?</a></li> <li class="action_buttons" style="margin-right:0" ><a id="button_addNormal" class="button_small">???s????</a></li> </ul> The problem is that i hide all of them except the anchor with id = button_addNormal at $(document).ready()... Everything works fine but at chrome when i want to show them ,it displays them as display:inline and not as display:inline-block ... The css class button_small have display:inline-block.... Firefox,IE 6+ works ok... Havent tested on safari but i hope that it would be ok... Why chrome kills inline-block? The solution was to put .css("display","inline-block") instead of .show()

  • jquery selectors (finding tag)

    - by matthewsteiner
    I'm sure this is simple, but I can't seem to figure it out. I need to be able to pass a function an element id, and know what element tag it is. For example: <a id="first"></a> <input id="last" /> If I know the id is "first", how can I get that the tag is "a"?

  • scrollTop with jQuery

    - by Narcís
    I want a foot to be at the bottom of the page. But when the user makes the window smaller, the two divs come together, it would be better that begins the scroll and hides the foot. I don't know if I explain? I have the code life here: http://jsfiddle.net/mdAsn/ $(function(){ $(document).scroll(function(){ var topDistance = $('#foot').scrollTop(); if(topDistance >= 420){ $('#foot').css({position: 'absolute',bottom:'10px'}); } else{ $('#foot').css({position: 'absolute',top:'410px'}); } }); })

  • jQuery infinite loop w/ tablesorter

    - by Wells
    Got myself in a funny situation: page has three tables. Using sortEnd, any time you sort one table, it sorts the other three. However, since I bound sortEnd to the function that does the sorting, you get a infinite loop of sorting/resorting. It looks like: $("table.tablesorter").tablesorter({widgets: ['zebra']}).bind("sortEnd", function() { $(this).find("th.headerSortDown,.headerSortUp").each(function(i) { index = $(this).attr("cellIndex"); order = ($(this).is(".headerSortDown")) ? 1 : 0; $("table.tablesorter").tablesorter({sortList: [[index,order]]}); }); }); Any tips on how to clean this up?

  • jquery dynamically genearate element id in a loop

    - by phil
    This is a loop in a function intending to create elements <li> and give each <li> an unique id. But it's not working. I suspect it's a simple syntax error with the use of quote in .attr(). But I can't get a straight answer from Google. for (i=0;i<array.length;i++) { //create HTML element of tag li $('#suggest').append("<li></li>"); $("li").attr("id",'li'+i); $('#li'+i).html(array[i]); }

  • JQuery Dialog with constant aspect ratio

    - by David Semeria
    I need to display an image in a resizable dialog (so far all the specific image popup libraries I have tried do not fit my needs). All I want to do is maintain the aspect ratio during resizing. Sounds easy, but it's not. I thought something like this might work, but no dice: var d = $("").dialog({title:title, width:400, height:400}); d.resizable( "option", "aspectRatio", true ); Any pointers greatly appreciated, tks

  • jquery .get/.post not working on ie 7 or 8, works fine in ff

    - by Samutz
    I have basically this on a page: <script type="text/javascript"> function refresh_context() { $("#ajax-context").html("Searching..."); $.get("/ajax/ldap_search.php", {cn: $("#username").val()}, function(xml) { $("#ajax-context").html($("display", xml).text()); $("#context").val($("context", xml).text()); }, 'xml'); } $(document).ready(function() { $("#username").blur(refresh_context); }); </script> <input type="text" name="username" id="username" maxlength="255" value="" /> <input type="hidden" name="context" id="context" value=""/> <div id="ajax-context"></div> What it should do (and does fine on Firefox) is when you type a username in to the #username field, it will run /ajax/ldap_search.php?cn=$username, which searches our company's ldap for the username and returns it's raw context and a formatted version of the context like this: <result> <display>Staff -&gt; Accounting -&gt; John Smith</display> <context>cn=jsmith,ou=Accounting,ou=Staff,ou=Users,o=MyOrg</context> </result> The formatted version (display) goes to the div #ajax-context and goes to the hidden input #context. (Also, the - are actually - "& g t ;" (without spaces)). However, on IE the div stays stuck on "Searching..." and the hidden input value stays blank. I've tried both .get and .post and neither work. I'm sure it's failing on the .get because if I try this, I don't even get the alert: $.get("/ajax/ldap_search.php", {cn: $("#username").val()}, function() { alert("Check"); }); Also, IE doesn't give me any script errors. Edit: Added "$(document).ready(function() {", the .blur was already in it in my code, but I forgot to include that in my post. Edit 2: The request is being sent and apache2 is receiving it: 10.135.128.96 - - [01/May/2009:10:04:27 -0500] "GET /ajax/ldap_search.php?cn=i_typed_this_in_IE HTTP/1.1" 200 69

  • jQuery - Wait until image loads before performing function

    - by Steven
    I'm trying to create a simple portfolio page. I have a list of thumbs and an image. When you click on a thumb, the image will change. When a thumbnail is clicked, I'd like to have the image fade out, wait until the image is loaded, then fade back in. The problem I have right now is that some of the images are pretty big, so it fades out, then fades back in immediately, sometimes while the image is still loading. I'd like to avoid using setTimeout, since sometimes an image will load faster or slower than the time I set. Here's my code: $(function() { $('img#image').attr("src", $('ul#thumbs li:first img').attr("src")); $('ul#thumbs li img').click(function() { $('img#image').fadeOut(700); var src = $(this).attr("src"); $('img#image').attr("src", src); $('img#image').fadeIn(700); }); }); <img id="image" src="" alt="" /> <ul id="thumbs"> <li><img src="/images/thumb1.png" /></li> <li><img src="/images/thumb2.png" /></li> <li><img src="/images/thumb3.png" /></li> </ul>

  • jQuery FadeTo() bg on rollover, IMG animate().width height

    - by jg462095
    Hello all, I have been reading StackOverflow for a while and now I have a question I cannot find an answer to. i am trying to fade a background and increase on img size on rollover. I have tried animate() and fadeTo(), however, the entire div fades. Do I need to absolute position my images over the div and not within it? img or img? Is that the only way to get items within a div to not fade along with the background? Thanks! Jason

  • jQuery Validation Plugin ErrorPlacement inside two different elements

    - by Andy Poquette
    I'm trying to place separate error messages in separate elements when validating a large form. The form is divided into jQueryUI tabs, then accordions. When there is an error in an element of a tab, I want to append a red exclamation point to the name of the tab, and if the error is in an accordion element, I also want to append the red exclamation point to the name of the accordion element. Subsequently, when the errors are corrected, I would like those red ! to be removed (exactly as the error message beneath the invalid field is removed. So: Tab1 Tab2 Accordion1 Accordion2 Tab3 If the elements in accordion 2 have an error, I want to append a red ! to accordion2 and tab2: Tab1 Tab2! Accordion1 Accordion2! Tab3 Then remove when the elements successfully validate. I've been trying forever, but I can't figure out how to conditionally change the errorElement (a label won't work for the tab and accordion, but is perfect for the actual element)... Hopefully this makes sense, and thanks for any input you can provide.

  • Temporarily Disallow JQuery Toggle

    - by Kevin Sylvestre
    I have a menu that is toggled when a user selects a link. The menu has an animation attached, and I want to prevent toggling while the animation is running. The following snippet works, but flips the state of toggle if the link is clicked quickly twice (i.e. if the user clicks the link quickly twice, the next click will trigger the same action): <a href="" id="button">Menu</a> <div id="menu">...</a> <script> $("#button").toggle( function (e) { if $("#menu").is(":animated")) return false; $menu.show("slow"); }, function (e) { if ("#menu").is(":animated")) return false; $menu.hide("slow"); } ); </script> How can I prevent switching states within toggle? Thanks.

  • load data from external file jQuery

    - by bah
    Hi, I need to take data from external file and format it, the problem is, i want to have that data stored into a variable. Load method works for me, because i need to load not the whole document, but just a part of it, but then again, i want to load to variable and not to some dom element. $.get can do this, but it doesn't support selectors. Is there any way I could make this? Now examples: Mine external file consists of a table, which has format like this: <table><tr><td><img /></td></tr><tr><td><a></a></td><td><span></span></td></tr></table> I need to extract img, a and span tags because I need them to be displayed in different order than they're now. So, is there any chance for me that i could make this work? Thanks.
