  • jQuery Mobile tap bug : same target twice

    - by hugo
    I'm working on displaying some text in an UIWebView on iOS. I'd like to get the content of the HTML element tapped by the user. If he taps on a paragraph for example, a popup shows the paragraph content. I'm using jQuery Mobile to achieve this. Here's what I'm doing : $('body').tap(function(e) { var tappedElement = $(e.target); alert(tappedElement.text()); }); It works for the first tap. The second tap no matter where it is, returns the same text. The event seems to be ok but the target property of the second tap is wrong. On the third tap all comes back to normal and so on ... What am I missing here ? thx

  • Can't get jQuery and IE to be friends

    - by Matthew
    Using jQuery and the Cycle plugin. Runs flawless in Safari, Chrome, Firefox, and the latest version of Opera. Won't run in older versions of Opera, and of course, IE. I know its running Java, because its picking up the rollovers. This is driving me batty. Hopefully its something simple. Here's the code... $(document).ready(function() { $("#slideshow").css("overflow", "hidden"); $("div#slides").cycle({ fx: 'scrollHorz', speed: 'slow', timeout: 0, prev: '#prev', next: '#next' }); Really appreciate the help guys.

  • JQuery selector: pass on id from array into function

    - by user347256
    I have a list of items <div id="item1">somestuff</div> <div id="item2">somestuff</div> <div id="item3">somestuff</div> When someone clicks on one of these, I need to take some actions based on the id (the number). Let's say hide it. How can I make the function generic, and how can I pass the id into the function? $(document).ready(function() { $("#item-howcanImakethisselectorgeneric?").click(function () { $("#item-andhowcanIpasshteidintohere?").hide(); } } I'm a javascript/jquery newbie, any help (including rtfm) appreciated.

  • initialize jquery slider with hidden input value from database.

    - by ludwigs3rd
    I'm using a slider as user input for a screen. Basically it's a bulk update screen where there is a table with multiple rows, thus multiple sliders. I created it so that the hidden value is what gets posted in the form. <td> <input class="percentageProvidedHidden" type="hidden" name='<%= "Values[" + i + "].Percentage" %>' value='<%=item.Percentage %>' /> <div class="percentageProvidedSlider"></div> </td> I have the update working just fine (move slider changes hidden input value, submit, values are updated in db), however, I can't get the damn thing to initialize with the value of the hidden input (note the "value: " parameter below). In this case I think $(this) isn't actually $('percentageProvidedSlider') but the page itself. Can someone help me get the slider value to initialize with the hidden input field? I'm using ASP .Net MVC 2 so if there are any methods I should try with that I welcome them as well. $('.percentageProvidedSlider').slider( { min: 0, max: 100, step: 25, value: $(this).parents('tr').find('input.percentageProvidedHidden').val(), slide: function(e, ui) { var mypos = ui.value; $(this).find('.ui-slider-handle').text(ui.value); }, change: function(event, ui) { var myVal = $(this).slider("option", "value"); $(this).parents('tr').find('input.percentageProvidedHidden').val(myVal); var myDropDown = $(this).parents('tr').find('select.verified'); } });

  • jquery animate boxshadow

    - by mstef
    http://jsfiddle.net/mstefanko/w5aAn/877/ Below, i'm achieving the effect I wanted, but with a pending issue. Since i'm using a separate span and positioning it absolute over-top of a box with relative position. I can not access the inputs until after the animation is finished. I'm guessing the only way to alleviate this would be do something similar with just animating the border of the outer box? But nothing I was doing to animate box-shadow:inset was working. HTML <div id="wow"> <span id="pulse"></span> <input id="form-input"/> <input id="form-input"/> </div>? CSS #wow { width: 500px; height: 200px; display: inline-block; position: relative; border: 1px solid black; } #pulse { width: 100%; height: 100%; box-shadow:inset 0 0 20px #6c95c3; -moz-box-shadow:inset 0 0 10px #6c95c3; position: absolute; z-index: 20000; } JS $('#pulse').stop().animate({"opacity": 0}, "fast"); $('#pulse').effect("pulsate", { times:4 }, 500, function() { $(this).remove(); });

  • How to get the Primary/Secondary color in jQuery UI Theme

    - by simonsanderson
    Is there a way to reference the colours used in the jQuery themes without creating a simple style for each theme that I may choose to use? Example: I have some text as follows <div>Hello</div> which I'd like to be change colour in line with my theme of the day. I wish to use the primary colour from a theme (say ui-lightness) which is "#1c94c4" as defined in several of the styles such as ui-state-default in ui-lightness.css The problem is that if I do the following <div class='ui-state-default'>Hello</div> I get all the other style effects, like borders and background colour, which are not right for my application What I'd like to do is something like <div class='ui-primary-color'>Hello</div> which would automatically change only the colour dependent on the theme. PS. Doing a pre-build pre-processing step to parse the themes and generate a customised css style would be my least favourable option here!

  • jQuery is only returning first item

    - by Andy
    For some strange reason, whenever I have a selector and expect to get multiple items, jQuery is only returning the first item, instead of the entire collection. This is the HTML I have: <a id="reply-424880" class="reply" href="#" rel="nofollow">Reply</a> <a id="reply-424885" class="reply" href="#" rel="nofollow">Reply</a> And the selector: $('.reply').unbind('click').click(function(event) { ... } I have tried debugging using FireBug, and still get the same results. Using the work around I can get it to work: $('a').each(function (index, element) { if ($(element).attr('class') == 'reply') { $(this).unbind('click').click(function(event) { ... }); } }); I would like to use the built-in functionality instead of my work around. Any idea why only the first element would be returned?

  • jquery plugin pattern using jquery.data

    - by web_dev
    I have seen this piece of code in jquery plugin patterns and the notes section mention that we could attach the plugin to the DOM element using the jQuery.data function. What I don't understand is how do I make use of this piece of code. Can somebody provide examples of how to use this functionality and explain its significance? $.fn[pluginName] = function (options) { return $Extend(this).each(function () { if (!$.data(this, 'plugin_' + pluginName)) { $.data(this, 'plugin_' + pluginName, new Plugin( this, options )); } }); };

  • Trouble with Perfect Scrollbar jQuery

    - by coolpup
    I'm using the Perfect Scrollbar jQuery app (http://www.yuiazu.net/perfect-scrollbar/) for this site: http://thehummingbirdplace.com/ The scrollbar shows up when you hover over the News section, but it won't scroll down to reveal the content. I've used this scrollbar before successfully, so I'm stumped as to what is different now. I haven't been able to replicate this on a simpler page, when I experiment on another page it either works or just vanishes, so I'm not sure why it is successfully showing up, yet not scrolling on the main page. Any help would be appreciated!!

  • Best use of Jquery sliders and PHP

    - by Coronier
    Hello there, I have two questions: What's the best way to send sliders' values to a PHP page ? I'm associating each slider (several per page) with an hidden form so far, but I wonder if there's a "cleaner" way to do this. Related to the 1st question; I've some trouble with the script: var score = $(this).slider( "option", "value" ); $(this).closest("input[type=='hidden']").val(score); It doesn't set the value of the hidden input. Can somebody tells me what's wrong ? Thanks

  • Calling a function when using <button> tag with jQuery Mobile

    - by u2sonderzug
    I already asked a similar question for buttons in tags, but I find that solution doesn't work using tags. So, if I am using a script that references jQuery Mobile I have the following line: <button id="buttonAnswer1" data-inline="true">Click me</button> How would I add a listener for when this button is clicked and lets say call the hello() function? i.e. <button id="buttonAnswer1" data-inline="true">Click me</button> <script> function hello(){ console.log("hello world"); } </script>

  • Problems with jQuery getJSON using local files in Chrome

    - by Tauren
    I have a very simple test page that uses XHR requests with jQuery's $.getJSON and $.ajax methods. The same page works in some situations and not in others. Specificially, it doesn't work in Chrome on Ubuntu. I'm testing on Ubuntu 9.10 with Chrome 5.0.342.7 beta and Mac OSX 10.6.2 with Chrome 5.0.307.9 beta. It works correctly when files are installed on a web server from both Ubuntu/Chrome and Mac/Chrome (try it out here). It works correctly when files are installed on local hard drive in Mac/Chrome (accessed with file:///...). It FAILS when files are installed on local hard drive in Ubuntu/Chrome (access with file:///...). The small set of 3 files can be downloaded in a tar/gzip file from here: http://issues.tauren.com/testjson/testjson.tgz When it works, the Chrome console will say: XHR finished loading: "http://issues.tauren.com/testjson/data.json". index.html:16Using getJSON index.html:21 Object result: "success" __proto__: Object index.html:22success XHR finished loading: "http://issues.tauren.com/testjson/data.json". index.html:29Using ajax with json dataType index.html:34 Object result: "success" __proto__: Object index.html:35success XHR finished loading: "http://issues.tauren.com/testjson/data.json". index.html:46Using ajax with text dataType index.html:51{"result":"success"} index.html:52undefined When it doesn't work, the Chrome console will show this: index.html:16Using getJSON index.html:21null index.html:22Uncaught TypeError: Cannot read property 'result' of null index.html:29Using ajax with json dataType index.html:34null index.html:35Uncaught TypeError: Cannot read property 'result' of null index.html:46Using ajax with text dataType index.html:51 index.html:52undefined Notice that it doesn't even show the XHR requests, although the success handler is run. I swear this was working previously in Ubuntu/Chrome, and am worried something got messed up. I already uninstalled and reinstalled Chrome, but that didn't help. Can someone try it out locally on your Ubuntu system and tell me if you have any troubles? Note that it seems to be working fine in Firefox.

  • jQuery UI dialog on ASP.NET page (inside user control)

    - by marc_s
    I have a really odd behavior here: I created a little popup dialog in jQuery UI, and in my test HTML page, it works flawlessly. When I click on the button, the popup comes up, covers the background, and remains on screen until I click on one of the two buttons (OK or Cancel) provided. So now I wanted to add this into my ASP.NET 3.5 app. I wanted to add it to a GridView inside a user controls (ASCX), which is on a page (ASPX) contained inside a master page. The jQuery 1.4.2 and jQuery UI 1.8.1 scripts are referenced on the master page: <body> <form id="XXXXXX" runat="server"> <Ajax:ScriptManager ID="masterScriptManager" runat="server" ScriptMode="Auto"> <Scripts> <asp:ScriptReference Path="~/Scripts/jquery-1.4.2.min.js" /> <asp:ScriptReference Path="~/Scripts/jquery-ui-1.8.1.custom.min.js" /> </Scripts> </Ajax:ScriptManager> I had to change this to use the Ajax script manager, since adding them to the as never worked. So in my gridview, I have a column with image buttons, and when the user clicks on those, I am calling a little javascript function to show the jQuery UI dialog: function showDialog() { $("#dlg-discount").dialog('open'); $("#txtAmount").focus(); } When I run this page in MS IE 8, I get a separate page, and at the top of the page, I get the contents of my , with proper background color and all. In Firefox 3.5.6, I do get the dialog as a popup. In both cases, the dialog page/popup disappears again after a second or less - without me clicking anything! It seems similar to this question but the solution provided there doesn't work in my case. This one here also seems similar but again: the solution presented doesn't seem to work in my case... Any ideas / hints / tips on what the h** is going on here?? Thanks!

  • jQuery autocomplete - update options on dynamically created elements

    - by Ian Robinson
    Background The user enters values into multiple inputs on the page. Think of entering a list of widgets for sale. The user would select the type of a widget from a drop down. Then enter the name of the Widget vendor, and then the actual name of the widget. These UI elements would all appear as one row. The user is able to click an "add another widget" link and a new row is created. The two input elements have autocomplete functionality attached to them using the DevBridge jQuery plugin. It suggests the name of the vendor and the name of the widget. I have recently wired up the logic to filter the name of the widget based on the name of the vendor you entered. This means setting the (custom) vendorName parameter when attaching the autocomplete plugin so it can be passed to the server side to retrieve the widget names for that vendor that match the name the user entered. To achieve this functionality I'm dynamically attaching the autocomplete functionality to the second element (the widget name text box) when it receives focus. Here is an example: $('.autocomplete-widget').live('focus', function () { $(this).autocomplete({ serviceUrl: '/something.ashx', params: { type: 'widget', vendorName: $(this).parent().prev().find('.autocomplete-vendor').val()} }); }); Problem At first glance, this looks to function quite well. However I started noticing some inconsistencies, and upon inspection, I found out that the call to the server is actually happening several times in some cases. Each time the widget name input element receives focus the autocomplete functionality is attached. And what I'm seeing is that the call to the server is made in proportion to how many times the input element has gained focus. I'd like to avoid making the call more than once, but retain the ability to attach (or update) the autocomplete functionality "on focus". I've tried to use the autocomplete 'setOptions' method but have only been able to get it to work with the static elements, not the dynamically created elements. Question Is there a way I can clear out the autocomplete functionality before I attach another one?

  • jQuery: AJAX umlauts & special characters are a mess

    - by rayne
    I've just created my first ajax function with jQuery which actually works, but unfortunately the character encoding (for characters like ä, ö, ü, ß, c, c, å, ø) is a nightmare. My files and my database are all UTF-8. I've tried a multitude of options in the ajax function and the PHP function, none of which were satisfactory. This is my ajax var dataString = { 'name': name, 'mail': mail // other stuff } $.ajax({ type: "POST", url: "/post.php", data: dataString, contentType: "application/x-www-form-urlencoded;charset=UTF-8", cache: false, success: function(html){ // do stuff } I've tried it without contentType: "application/x-www-form-urlencoded;charset=UTF-8" and I've tried to wrap the affected data in encodeURIComponent(), none of which worked. When I use that AJAX with htmlentities() in my php, my umlauts look like this in plain text: UE Ã?, AE Ã?, OE Ã?, ue ü, ae ä, oe o And like this in the database: UE Ãœ , AE Ä, OE Ö, ue ü, ae ä, oe o If I don't use htmlentities() but mysql_real_escape_string() instead (or neither), they look good in plain text, but they look like this in the database: AE Ä, OE Ö, UE Ãœ, ae ä oe ö ue ü I've been trying tons of options for hours now, but I can't find a solution that works. So far the only option I seem to have is having them look like a total mess in the database, but that would be very contraproductive if those data sets need to be edited.

  • jquery validate: focusCleanup: true and focusInvalid: false don't work as expected

    - by laramichaels
    I am using Joern's jquery validation plugin 1.6. My goal is to have the following behavior: remove the error message for an element once the user focuses it. From what I understand setting 'focusCleanup: true' should take care of this. However (at least on my browser (Firefox 3.5.7 on Linux)), I only get the desired behavior (ie, error message for a field disappearing once you focus it) if I click into the field; it doesn't handle tabbing into the field correctly. Sample code: HTML: <form id='abc' name='abc'> <input type="text" id="t1" name="t1"/> <input type="text" id="t2" name="t2"/> <input type="submit" id="submit" value='submit'/> </form> JS: $("#abc").validate({ focusCleanup: true, focusInvalid: false, rules: {t1: {required: true, email:true}, t2: {required: true,email:true}} }); I am setting 'focusInvalid: false' because the docs say one should avoid combining focusCleanup and focusInvalid; in my experience commenting out that line makes no difference. Am I doing something wrong?

  • jQuery Validation Plugin: Validating Checkboxes with Different Names

    - by Michael
    I have a set of 4 checkboxes, all with different names, and require that at least 1 is checked. I know there are a few posts on here already trying to answer this question. The solution that seems to be most logical to me is the answer posted on Question 1734840, but I can't seem to get it working! What's wrong with my code? Or any other new coding ideas to get this working? I have set the class on all of them to 'require-one'. My jQuery code is $(document).ready(function(){ $("#itemForm").validate({ highlight: function(element, errorClass, validClass) { $(element).addClass(errorClass).removeClass(validClass); $(element.form).find("label[for=" + element.name + "]") .addClass("radioerror"); }, unhighlight: function(element, errorClass, validClass) { $(element).removeClass(errorClass).addClass(validClass); $(element.form).find("label[for=" + element.name + "]") .removeClass("radioerror"); }, rules: { 'require-one': { required : { depends: function(element) { var allBoxes = $('.require-one'); if (allBoxes.filter(':checked').length == 0) { if (allBoxes.eq(element).length != 0) { return true; } } return false; } } } , }, errorPlacement: function(error, element) { if ( element.is("#other_descrip") ) error.appendTo("#othererror" ); if ( element.is("#itemlist") ) error.appendTo("#itemerror" ); } }); });

  • jQuery not and classes

    - by Giles B
    Hi Guys, I have 2 anchor links (a.selector) and when one is clicked it has a class applied to it of 'active-arrow' and the click also removes the class of the same name from the other anchor as well as lowering the opacity to 0.2. I then want to have a fade effect when the user hovers over the anchor that doesn't have 'active-arrow' applied to it so that it goes to full opacity when mouseenters and back to 0.2 when mouseleaves. The problem im having is that both .not and :not don't seem to be working as expected, the hover effect works but if I click on the anchor whilst hovering the 'active-arrow' class is applied but when mouseleaves the opacity is faded down to 0.2 again even though the 'active-arrow' class is applied. Also the hover then doesn't work for the other a link which has had 'active-arrow' removed. Bit of a hard one to explain so heres some code that hopefully helps a bit. *//If a.selector doesn't have the class 'active-arrow' then run the hoverFade function* $("a.selector").not(".active-arrow").hoverFade(); //Functions for first element $('a.selector-1').click(function () { $('a.selector-2').removeClass('active-arrow'); //Remove background image from corresponding element $('ul#storage-items-2').fadeOut(1200).addClass('hide'); //Fade out then hide corresponding list $(this).addClass('active-arrow', 'fast'); //Add background image to current element $('ul#storage-items-1').removeClass('hide').fadeIn(1800); //Unhide and fade in the list $('a.selector-2').fadeTo(500, 0.2); //Fade corresponding element $(this).fadeTo(800, 1);//Fade this element to full opacity }); I only included the code for teh first anchor (a.selector-1) as the code for the second anchor is identical but just changes the class names to a.selector-2. Also the hoverFade function is in a seperate file so we can re-use it. jQuery.fn.hoverFade = function() { return this.each(function(){ $(this).hover( function () { $(this).fadeTo(500, 0.8); }, function () { $(this).fadeTo(500, 0.2); }); }); } Each anchor link fades in and fades out a UL as well. Any help is most appreciated Thanks Giles

  • loading js files and other dependent js files asynchronously

    - by taber
    I'm looking for a clean way to asynchronously load the following types of javascript files: a "core" js file (hmm, let's just call it, oh i don't know, "jquery!" haha), x number of js files that are dependent on the "core" js file being loaded, and y number of other unrelated js files. I have a couple ideas of how to go about it, but not sure what the best way is. I'd like to avoid loading scripts in the document body. So for example, I want the following 4 javascript files to load asynchronously, appropriately named: /js/my-contact-page-js-functions.js // unrelated/independent script /js/jquery-1.3.2.min.js // the "core" script /js/jquery.color.min.js // dependent on jquery being loaded http://thirdparty.com/js/third-party-tracking-script.js // another unrelated/independent script But this won't work because it's not guaranteed that jQuery is loaded before the color plugin... (function() { a=[ '/js/my-contact-page-functions.js', '/js/jquery-1.4.2.min.js', '/js/jquery.color.js', 'http://cdn.thirdparty.com/third-party-tracking-script.js', ], d=document, h=d.getElementsByTagName('head')[0], s, i, l=a.length; for(i=0;i<l;i++){ s=d.createElement('script'); s.type='text/javascript'; s.async=true; s.src=a[i]; h.appendChild(s); } })(); Is it pretty much not possible to load jquery and the color plugin asynchronously? (Since the color plugin requires that jQuery is loaded first.) The first method I was considering is to just combine the color plugin script with jQuery source into one file. Then another idea I had was loading the color plugin like so: $(window).ready(function() { $.getScript("/js/jquery.color.js"); }); Anyone have any thoughts on how you'd go about this? Thanks!

  • Scrollable list items in jQuery

    - by Giles B
    Hi Guys, I have a list of 4 items and the ul has a background image that makes the second item look as though it has an arrow behind it. I want to be able to scroll the items up or down when they are clicked to the second items position so for example when I click the fourth item the whole list scrolls up so the fourth item is then postioned over the top of the background image and all the other items will be sitting in the same order above it. I have tried using jQuery Tools with the circular option selected but it clones the first an last item and i end up with a gap when i get to the bottom and I also cant make each item selectable to scroll the list up or down. Here is the code for the list <div id="priceGuide"> <ul id="priceRegion"> <li><a href="#">North & Midlands</a></li> <li><a href="#">London, north of the river</a></li> <li><a href="#">London, south of the river</a></li> <li><a href="#">South & South East</a></li> </ul><!-- /priceRegion --> </div><!-- /priceGuide --> Any help is most appreciated.

  • Internet explorer only executing function inside jQuery ajax success response once even though there

    - by user249950
    Hi, I have a function that uses jQuery.load() to call in 3 snippets of forms from different pages and then on the success text status it tries to load a colour picker: $(document).ready(function() { function ajax_form(putloadingboxhere, putsnippethere, snippeturl) { $(putsnippethere).load(snippeturl, function (responseText, textStatus, XMLHttpRequest, ) { if (textStatus == "success") { alert('One') $("input.pickcolor").ColorPicker({ onShow: function (colpkr) { $(colpkr).fadeIn(500); return false; }, onSubmit: function(hsb, hex, rgb, el) { $(el).val(hex); $(el).ColorPickerHide(); $(el).siblings('.colorpreview').css('background-color', '#' + hex); }, onBeforeShow: function () { $(this).ColorPickerSetColor(this.value); } }) .bind('keyup', function(){ $(this).ColorPickerSetColor(this.value); }); alert('Two') } if (textStatus == "error") { // Show error message } }); } ajax_form('tab_box', '#formone', 'snippet_one.htm #snippet'); ajax_form('tab_box', '#formtwo', 'snippet_two_copy.htm #snippet'); ajax_form('tab_box', '#formthree', 'snippet_three.htm #snippet'); }); It works fine in Firefox and Safari but (surprise, surprise) IE has a problem with it. I have added an alert to see what is going on before and after one of the functions. FF & Safari & IE8: Alert 'one' and Alert 'two' appear three times as expected and colour picker appears. IE6 & 7: Alert 'one' shows three times and colour picker does not appear. Any help would be great! Cheers. EDIT The line IE is referring to when it throws this error: 'Error: Object doesn't support this property or method.' is: $('input.pickcolor').ColorPicker Anyone got any insights? Thanks
