  • jQuery not refreshing tabs content in IE

    - by iddimu
    Hi all! I have a page that is using jQuery tabs. Within one of my tabs I have a div that contains a form (initially hidden) that I want to use to add content to the tab. What I have works perfectly in Chrome, Firefox, and Safari. But, in IE 7 the tab will not refresh. The post works and the data gets added to the database, but it simply will not show the new content after submitting it. I don't think it matters - but, just for information I am using the Codeigniter PHP framework as well. Here is my javascript: <script type="text/javascript"> $(document).ready(function(){ // initialize the addChild form as hidden until user requests it open $('#addChild').hide(); // open the form $('#openDialog').click( function(){ $('#addChild').slideToggle(); return false; }); // close the form $('#closeDialog').click( function(){ $('#addChild').slideToggle(); return false; }); // submit the form $('#frmAddChild').submit( function(){ $('#addChild').slideToggle(); $.ajax({ url: '/children/add', type: 'POST', data: $('#frmAddChild').serialize() //cache: false }); //reload the children tab $('#tabs').tabs('load',3); return false; }); }); </script> And, here is my PHP/HTML: <?php // initialize the elements of the form $frmAddChild = array( 'name' => 'frmAddChild', 'id' => 'frmAddChild', 'method' => 'post' ); $child_name = array( 'name' => 'child_name', 'id' => 'child_name', ); $child_dob = array( 'name' => 'child_dob', 'id' => 'child_dob' ); $btnOpenDialog = array( 'name' => 'openDialog', 'id' => 'openDialog', 'value' => 'true', 'content' => 'Add Child' ); $btnCloseDialog = array( 'name' => 'closeDialog', 'id' => 'closeDialog', 'value' => 'true', 'content' => 'Cancel' ); // button that shows the drop down to add echo form_button($btnOpenDialog); ?> <div id="addChild" title="Add Child"> <?php echo form_open('children/add/',$frmAddChild); ?> <table> <tr> <td> <?php echo form_label('Child\'s Name', 'child_name'); ?>: </td> <td> <?php echo form_input($child_name); ?> </td> </tr> <tr> <td> <?php echo form_label('Date of Birth','child_dob'); ?>: </td> <td> <?php echo form_input($child_dob); ?> </td> </tr> <tr> <td colspan="2" align="right"> <?php echo form_submit('submit', 'Add'); ?> <?php echo form_button($btnCloseDialog); ?> </td> </tr> </table> <?php echo form_close(); ?> </div> Does anyone have any ideas how I can get this working correctly in IE? Also, if anyone has any comments about how I have things structured, please let me know. I'm new to Codeigniter and I am by no means a javascript or jQuery expert. Thanks for your help!

  • jQuery class adding and removing with click and mouseleave

    - by danixd
    I just want to control a div by toggling a class on click, as well as removing it when the mouse leaves the div. I had it working with mouseout, but when I entered over a child element, the mouseOut triggered, so I know I need to use mouseleave. I am just unsure how incorporate telling jQuery the mouse has entered. Yes I am new to this! Here is my code: $(function(){ $('.main').click(function() { $(this).toggleClass('activated'); }); }); $(function(){ $('.main').mouseleave(function() { $(this).removeClass('activated'); }); });

  • Toggle 1 <div> at a time with Image Changing using JQuery

    - by dg
    Please see this site: http://www.sensationsskin.com/site10/treatments/skin-care.html I've got it working, but am wanting the "+" to change to the "-" (expandbutton-close.gif). I'm using CSS right now to pull up the image, but I think I need to incorporate it into the JQuery code? <script type="text/javascript"> $(document).ready(function(){ //hide the all of the element with class msg_body $(".msg_body").hide(); //toggle the componenet with class msg_body $(".msg_head").click(function(){ if ( $(this).next(".msg_body").is(':visible') ) { $(".msg_body").hide(); } else { $(".msg_body").hide(); $(this).next(".msg_body").slideToggle(450); } }); }); </script>

  • JQuery/JavaScript div tag "containment" approach/algorithm?

    - by Pete Alvin
    Background: I've created an online circuit design application where div tags are containers that contain smaller div containers and so forth. Question: For any particular div tag I need to quickly identify if it contains other div tags (that may in turn contain other div tags). I've searched JQuery and I don't see any built-in routine for this. Does anyone know of an algorithm that's quicker than O(n^2)? Seems like I have to walk the list of div tags in an outer loop (n) and have an inner loop (another n) to compare against all other div tags and do a "containment test" (position, width, height), building a list of contained div tags. That's n-squared. Then I have to build a list of all nested div tags by concatenating contained lists. So the total would be O(n^2)+n. There must be a better way?

  • jQuery default/placeholder input text and problems with saved information

    - by user318106
    Hey Guys, I'm new to jQuery and have an annoying problem. I have some login fields that are filled with default text when the field is empty and then removed when clicked. My problem is that when the user has their username/password saved (with browser), if they return to the page the login fields are filled with the users saved input as well as the default input. $('#login input.text').each(function(i, field) { field = $(field); if (field.val().length 0) { field.prev().css('display', 'none'); } field.focus(function() { field.prev().css('display', 'none'); }).blur(function() { if (field.val() == '') field.prev().css('display', 'block'); }); })

  • jQuery + Validation plugin: add/remove class to/from element's parent

    - by FreekOne
    Hi guys, I'm working with the jQuery Validation plugin and I wrote the following code which adds a class to the element's parent if not valid (as well as inserting the actual error message at a particular location within the parent): errorPlacement: function(error, element) { element.parent().addClass('error'); error.insertBefore(element.parent().children("br")); } This works, however, if a field's content is corrected and becomes valid, the class obviously doesn't get removed from its parent (actually, neither does the error element, instead it just gets a display: none; CSS property). How can I check if an element becomes valid and remove its parent class if so ? Any help would be much appreciated, thank you !

  • jQuery.load and form elements

    - by Jez
    Is jQuery's .load() supposed to be able to load elements? Because it seems to be stripping them out. So I have some code like: var $dialogContents = $('<div></div>').load($link.attr('href') + ' #divDlgContent', function() { ... } and when the $dialogcontents loads, I return some content with a inside the DIV with the id 'divDlgContent'. Although the rest of the HTML is loaded, the tags are stripped out. Is this by design, and is there a way I can load elements this way?

  • I can't change HTTP request header Content-Type value using jQuery

    - by Matt
    Hi I tried to override HTTP request header content by using jQuery's AJAX function. It looks like this $.ajax({ type : "POST", url : url, data : data, contentType: "application/x-www-form-urlencoded;charset=big5", beforeSend: function(xhr) { xhr.setRequestHeader("Accept-Charset","big5"); xhr.setRequestHeader("Content-Type","application/x-www-form-urlencoded;charset=big5"); }, success: function(rs) { target.html(rs); } }); Content-Type header is default to "application/x-www-form-urlencoded; charset=UTF-8", but it obviously I can't override its value no matter I use 'contentType' or 'beforeSend' approaches. Could anyone adivse me a hint that how do I or can I change the HTTP request's content-type value? thanks a lot. btw, is there any good documentation that I can study JavaScript's XMLHttpRequest's encoding handling?

  • Issue on passing a checkbox set to an AppEngine script through jQuery Ajax/Json

    - by Jorge
    I have a set of checkboxes with multiple choice allowed. I parse the set this way: if ($("input[name='route_day']:checked").length > 0) { $("input[name='route_day']:checked").each(function(){ if(this.value != null) route_days_hook.push(this.value); }); dataTrap.route_days = $.JSON.encode(route_days_hook); } ...and pull the whole dataTrap to an AppEngine Python script via jQuery ajax. However, the Python script just bugs. If i change dataTrap.route_days value to a string instead of the JSON encoded object, everything works fine. My question is: how can i pass a checkbox set to the script using Ajax and still be able to iterate over it on the script?

  • Jquery SimpleModal flickers in Firefox

    - by Obay
    I'm using SimpleModal plugin for Jquery and I have a weird problem with Firefox ( other browsers work fine: Chrome, Safari, Opera, IE). What happens is when I click on the button that launches the modal dialog, before showing the modal (and the fadeIn of the overlay), there is a quick "flicker", less than half a second. (It's longer on my slower PC). Weird thing is, it didn't happen in Firefox 3.5.2, but when I upgraded to 3.6.3, I got the flicker. Any ideas? Here is my code: $("#popup").modal({ onOpen: function (dialog) { dialog.data.show(); dialog.container.show(); dialog.overlay.fadeIn('fast'); }, onClose: function (dialog) { dialog.data.hide(); dialog.container.hide(); dialog.overlay.fadeOut('fast', function() { $.modal.close(); }); } });

  • JQuery Tooltip and Scrollable Fix

    - by KrippledShark
    I have set up the navigation on my site using a scrollable div created with Flowplayer's JQuery tools. I also want to add a tooltip to the individual images within the scrollable div. The problem is the tooltip needs to appear outside of the div. I can adjust the height of the div so you can see the tooltip, but the tooltip is still constrained inside another div. Here is the link to my code. http://staging.asla.org/sustainablesites/TestAGAIN.html Is there a way to make this tooltip (div) appear out of it's containing divs?

  • Standalone jQuery "touch" method?

    - by dclowd9901
    So, I'm looking to implement the ability for a plugin I wrote to read a touch "swipe" from a touch-capable internet device, like an iPhone, iPad or android. Is there anything out there? I'm not looking for something as full as jQtouch, though was considering reverse engineering the code I would need out of it. Any suggestions on the best way to approach this? A snippet of code already available? Addendum: I realize in hindsight the solution won't strictly be jQuery, as I'm pretty sure there aren't any built-in methods to handle this. I would expect standard Javascript to find itself in the answer.

  • jQuery Validation using the class instead of the name value

    - by Matt
    Hi, I'd like to validate a form using the jquery validate plugin, but I'm unable to use the 'name' value within the html - as this is a field also used by the server app. Specifically, I need to limit the number of checkboxes checked from a group. (Maximum of 3.) All of the examples I have seen, use the name attribute of each element. What I'd like to do is use the class instead, and then declare a rule for that. html This works: <input class="checkBox" type="checkbox" id="i0000zxthy" name="salutation" value="1" /> This doesn't work, but is what I'm aiming for: <input class="checkBox" type="checkbox" id="i0000zxthy" name="i0000zxthy" value="1" /> javascript: var validator = $(".formToValidate").validate({ rules:{ "salutation":{ required:true, }, "checkBox":{ required:true, minlength:3 } } }); Is it possible to do this - is there a way of targeting the class instead of the name within the rules options? Or do I have to add a custom method? Cheers, Matt

  • jquery ajax vs browser url

    - by danwoods
    Hello all, I'm trying to use youtube's api to bring back a listing of a user's videos. The request url looks something like: http://gdata.youtube.com/feeds/api/users/username/uploads with 'username' being the correct username. This bring back the appropriate url in the browser. However when I try to access that url via jQuery's $.ajax or $.get functions, using something like: $.ajax({ //set parameters url: "http://gdata.youtube.com/feeds/api/users/username/uploads", type: "GET", //on success success: function (data) { alert("xml successfully captured\n\n" + data); }, //on error error:function (XMLHttpRequest, textStatus, errorThrown, data){ alert(" We're sorry, there seem to be a problem with our connection to youtube.\nYou can access all our videos here: http://www.youtube.com/user/username"); alert(data); } }); $.get("http://gdata.youtube.com/feeds/api/users/username/uploads", function(data){ alert("Data Loaded: " + data); }); I get an empty document returned. Any ideas why this is?

  • jQuery autocomplete: how to split the string result?

    - by Matt
    I have the following situation with an autocomplete plugin on an .aspx page. It is working fine. The result from the autocomplete search yields a product id and a product description is concatenated with it (i.e. 2099 -- A Product). I know that I need to use split() with this but where do I put it? I'm still rather new to jQuery and javascript. $(document).ready(function() { $('.divAutoComplete').autocomplete("LookupCodes.aspx?type=FC", { mustMatch: true }); });
