  • Need help with jQuery/AJAX call in Safari/Mac

    - by protohominid
    I've got something that works perfectly in FF and MSIE but it's not working properly in Safari. It's a form with selects that get updated via AJAX/jQuery from a MySQL DB. In Safari, when you select the first item, it correctly loads the options for the next select menu; however, when you choose one of those (which loads new options in a subsequent select menu), the whole form resets and is broken from that point on. Does anyone know of a Safari bug that would cause this? Here's the JS: $(document).ready(function(){ $("#searchForm select").change(updateSearchForm); }); function updateSearchForm() { $.ajax({ url: '/elements/search_form.php?ajax=true', data: $('#searchForm').serialize(), error:function(xhr,err){ alert("readyState: "+xhr.readyState+"\nstatus: "+xhr.status); alert("responseText: "+xhr.responseText); }, success: function(data) { $("#searchForm").html(data); $("#searchForm select").change(updateSearchForm); } }); } I can post the relevant PHP/HTML for the form, but it's lengthy. I'm relatively new to JS so I'm not sure where to start debugging this... TIA

  • Is there a more elegant solution than an if-statement with no else clause?

    - by Jay
    In the following code, if Control (the element that trigers Toggle's first OL) is not Visible it should be set Visible and all other Controls (Controls[i]) so be Hidden. .js function Toggle(Control){ var Controls=document.getElementsByTagName("ol",document.getElementById("Quote_App")); var Control=Control.getElementsByTagName("ol")[0]; if(Control.style.visibility!="visible"){ for(var i=0;i<Controls.length;i++){ if(Controls[i]!=Control){ Reveal("hide",20,0.3,Controls[i]); }else{ Reveal("show",20,0.3,Control); }; }; }else{ Reveal("hide",20,0.3,Control); }; }; Although the function [Toggle] works fine, it is actually setting Controls[i] to Hidden even if it is already. This is easily rectified by adding an If statement as in the code below, surely there is a more elegant solution, maybe a complex If condition? .js function Toggle(Control){ var Controls=document.getElementsByTagName("ol",document.getElementById("Quote_App")); var Control=Control.getElementsByTagName("ol")[0]; if(Control.style.visibility!="visible"){ for(var i=0;i<Controls.length;i++){ if(Controls[i]!=Control){ if(Controls[i].style.visibility=="visible"){ Reveal("hide",20,0.3,Controls[i]); }; }else{ Reveal("show",20,0.3,Control); }; }; }else{ Reveal("hide",20,0.3,Control); }; }; Your help is appreciated always.

  • sub menu border calls onmouseout event

    - by insanepaul
    I've created a simple menu and submenu with tags(not allowed to use ul elements). To access the submenu the user hovers their mouse over the menu item. I use the onmouseover and onmouseout events to either show or hide the sub menu depending on which item is selected. A pipe (|) is used to seperate each submenu item and this is what is causing me problems. When a user hovers their mouse above the pipe character the subMenu div calls the onmouseout event which is not what I want. So I added padding around the pipe character and a minus margin so that there were no gaps between the pipe character and the other elements. This worked for all browsers including IE8. But in IE7 (I haven't tested IE6 yet) the submenu div calls the onmouseout event when I touch the top bit of either the left or right border of the pipe character span element. <div id="subMenu" onmouseout="hideSubMenu()" > <div id="opinionSubMenu" onmouseover="showOpinionSubMenu()"> <a id="Blogs" href="HTMLNew.htm">BLOGS</a> <span class="SubMenuDelimiter">|</span> <a id="Comments" href="HTMLNew.htm">COMMENTS</a> <span class="SubMenuDelimiter">|</span> <a id="Views" href="HTMLNew.htm">VIEWS</a> </div> <div id="learningSubMenu" onmouseover="showLearningSubMenu()"> <a id="Articles" href="HTMLNew.htm">ARTICLES</a> <span class="SubMenuDelimiter">|</span> <a id="CoursesCases" href="HTMLNew.htm">COURSES & CASES</a> <span class="SubMenuDelimiter">|</span> <a id="PracticeImpact" href="HTMLNew.htm">PRACTICE IMPACT</a> </div> </div> This is my css class #subMenu{ padding:10px 0px; background-color:#F58F2D; font-weight:normal; text-decoration:none; font-family:Lucida Sans Unicode; font-size:14px; float:left; width:100%; display:none;} #Blogs, #Comments, #Views, #Articles { padding:10px 5px; background:none repeat scroll 0 0 transparent; color:#000000; font-weight:normal; text-decoration:none; border:solid 1px black;} #Blogs:hover, #Comments:hover, #Views:hover, #Articles:hover{ color:#ffffff; text-decoration:none;} .SubMenuDelimiter{ padding:10px 5px; margin:10px -5px;}

  • Convert UTC date to actual date and time

    - by evann
    I have a chart of bitcoin prices. I have the correct prices on the Y-axis, but I cannot get the correct time on the X-axis. The time shows up in a UTC format in my console. I am adding price and date to the series each iteration. I need to get the date of that particular result and find the YEAR, MONTH and DAY of that so I can put it in the right format. Any help is appreciated thanks. $.ajax({ url: "/chart/ajax_get_chart", // the URL of the controller action method dataType: "json", type: "GET", success: function (result) { var result = JSON.parse(result); series = []; for (var i = 0; i < result.length; i++) { tempArray = [parseFloat(result[i]['price'])]; tempDate = Date.parse(result[i]['date']); series.push(tempDate); series.push(tempArray); }

  • jQuery: How to use modifier keys on form submit?

    - by Svish
    Say I have a form that looks like this: [ Animal name input field ] Add button If I type a name and hit enter, an animal with the given name is added to a table. Works fine. What I would like now is to call the current way of working "quick add" and add a new feature called "slow add", which I am not quite sure how to do. Basically what I want is that if for example the shift key is held down when enter or the button is clicked, I want the form submit method to do something slightly different. In my case I want it to open up a form where more details on the animal can be added before it is added to the table. Problem is I'm not quite sure how to do this. I have tried add a FireBug console.info(eventData) in my current submit function and I have found that the eventData contains an altKey, shiftKey and controlKey property, but they are always undefined even when I hold those keys down. So, does anyone know how I can do something special in my submit handler when certain modifier keys were pressed when the form was submitted?

  • How to create a function and pass in variable length argument list?

    - by Jian Lin
    We can create a function p in the following code: var p = function() { }; if (typeof(console) != 'undefined' && console.log) { p = function() { console.log(arguments); }; } but the arguments are passed like an array to console.log, instead of passed one by one as in console.log(arguments[0], arguments[1], arguments[2], ... Is there a way to expand the arguments and pass to console.log like the way above? Note that if the original code were var p = function() { }; if (typeof(console) != 'undefined' && console.log) { p = console.log; } then it works well on Firefox and IE 8 but not on Chrome.

  • How to get attributes values separately for each container present on the webpage in jquery ?

    - by Rachel
    This question is in continuation to How to get attributes of container in jquer, I have different containers on my webpage and all of them have <div id = "some values"> now how can I get attributes values separately for each component ? Is there any way I can know which attribute id belong to which container div ? Currently I am using : var id = $( '.promotion' ).attr( 'id' ); But if I have multiple promotional components on page and all have same div attribute as id than how can I relate that this particular attribute id belonged to this specific container ? Update: I am having a function which is called for each container present on the page and so if I am using above mentioned code than will it not always return me the first match for id in the div and would never go to other divs and so I will always get same value for id which is for the first container ? If so than what is the work around for this ? Hope this question is clear.

  • How to protect and hidden form HTML/PHP with JS callback to AS3

    - by Jk_
    Hi guys, I'm developing a Flash website (as3) where I need to be able to upload directly to YouTube by using the DATA API. However in order to do so, I had to use a proper HTML form on top of my flash object. Why? Because of the Browser Based Upload restictions. I first hide the form using JQuery and with a little CSS the form is display just where I want it. Within flash I use ExternalInterface.call() to show/hide the form when I need it! ExternalInterface.call("YTUploader.showIt"); The upload process is working great my only problem is that the form can be displayed easily... You just need a tool like firebug and you can use the form wherever you want on my flash app. So I was wandering which will be the best way to 'protect' this form or the best way to limit its access. Any advices will be appreciated. Thanks for your time. Jk.

  • How to implement partial refresh like facebook like/comments?

    - by shillong
    We have java web application. Summary page will display list of rows. For each row, user can vote and add comments. Vote or add comments will commit immediately and refresh total vote number and comments count. We want to refresh current row instead of whole table just like Facebook does. If need, we can show the list of data with form format (iterator List of data) instead of table format. How to implement this feature base on JSF?

  • Get computed font size for DOM element in JS

    - by Pekka
    Is it possible to detect the computed font-size of a DOM element, taking into consideration generic settings made elsewhere (In the body tag for example), inherited values, and so on? A framework-independent approach would be nice, as I'm working on a script that should work standalone, but that is not a requirement of course. Background: I'm trying to tweak CKEditor's font selector plugin (source here) so that it always shows the font size of the current cursor position (as opposed to only when within a span that has an explicit font-size set, which is the current behaviour).

  • Jquery remove and add back click event

    - by London
    Is it possible to remove than add back click event to specific element? i.e I have a $("#elem").click(function{//some behaviour});, $(".elem").click(function{//some behaviour});(there are more than 1 element) while my other function getJson is executing I'd like to remove the click event from the #elem, and add it again onsuccess from getJson function, but preserve both mouseenter and mouseleave events the whole time? Or maybe create overlay to prevent clicking like in modal windows? is that better idea? edit : I've seen some really good answers, but there is one detail that I omitted not on purpose. There are more than one element, and I call the click function on the className not on elementId as I stated in the original question

  • Make multiple lightboxes (facebox) execute one after each other.

    - by Jigs
    I have a php application that sometimes creates two lightboxes on the same page - the result is the last one to be called is the only one shown. How might I ensure that they show one after anohter? I call a facebox at the bottom of the page like so: jQuery.facebox('blah'); Currently multiple facebox's are called like so: jQuery.facebox('blah');jQuery.facebox('blah2'); But only blah2 will ever show. I need to wait for 'blah' to close before calling 'blah2'...

  • jquery form validation, and submit-on-change

    - by Bee
    I want to make all my settings forms across my site confirm that changes are saved, kinda like facebook does if you make changes in a form and then try to navigate away without saving. So I'm disabling the submit button on the forms only enabling if the values change. I then prompt the user to hit save before they leave the page in the case that they do have changes pending. var form = $('form.edit'); if(form.length > 0) { var orig_str = form.serialize(); $(':submit',form).attr('disabled','disabled'); form.on('change keyup', function(){ if(form.serialize() == orig_str) { setConfirmUnload(false); $(':submit',form).attr('disabled','disabled'); } else { setConfirmUnload(true); $(':submit',form).removeAttr('disabled') } }); $('input[type=submit]').click(function(){ setConfirmUnload(false); }); } function setConfirmUnload(on) { window.onbeforeunload = (on) ? unloadMessage : null; } function unloadMessage() { return 'If you navigate away from this page without saving your changes, they will be lost.'; } One of these forms needs some additional validation which I do using jQuery.validate library. e.g. if i wanted to ensure the user can't double submit the form on accident by double clicking on submit or somesuch (the actual validation in question is for a credit-card form and not this simple): $('form').validate({ submitHandler: function(form) { $(':submit', form).attr('disabled','disabled'); form.submit(); } }); Unfortunately both bits are trying to bind to submit button and they're interfering with each other such that the submit button remains disabled no matter what I do and it is impossible to submit the form at all. Is there some way to chain the validations together or something? Or some other way to avoid re-writing the validation code to repeat the "did you change anything in the form" business?

  • Need some explanation about MS Ajax using PageMethods

    - by Ahmed Said
    I have a project that uses PageMethods to call functions on the server. The server functions (written in C#) return the values as array of strings, without doing any kind of serialization and in the client side (from Js) the accessing of the return values is by using static variable called arguments. I found that sometimes for some users (cases are not repro) sometimes an exception occured "WebServiceFailedException the server method 'Foo' returned invalid data. the 'd' property is missing from JSON." Some searching on google I found that people are serializing the return values using DataContractJsonSerializer class and in js accessing the return value using one of the callback function Example: function OnRequestComplete(result, userContext, methodName) { var Person = eval('(' + result + ')'); alert(Person.Forename); alert(Person.Surname); } So is the first technique is correct? or what?

  • is it possible that a greasemonkey script can work on one computer but not on another?

    - by plastic cloud
    i'm writing an greasemonkey script for somebody else. he is a moderator and i am not. and the script will help him do some moderating things. now the script works for me. as far as it can work for me.(as i am not a mod) but even those things that work for me are not working for him.. i checked his version of greasemonkey plugin and firefox and he is up to date. only thing that's really different is that i'm on a mac and he is pc, but i wouldn't think that would be any problem. this is one of the functions that is not working for him. he does gets the first and third GM_log message. but not the second one ("got some(1) .."). kmmh.trackNames = function(){ GM_log("starting to get names from the first "+kmmh.topAmount+" page(s) from leaderboard."); kmmh.leaderboardlist = []; for (var p=1; p<=(kmmh.topAmount); p++){ var page = "http://www.somegamesite.com/leaderboard?page="+ p; var boardHTML = ""; dojo.xhrGet({ url: page, sync: true, load: function(response){ boardHTML = response; GM_log("got some (1) => "+boardHTML.length); }, handleAs: "text" }); GM_log("got some (2) => "+boardHTML.length); //create dummy div and place leaderboard html in there var dummy = dojo.create('div', { innerHTML: boardHTML }); //search through it var searchN = dojo.query('.notcurrent', dummy).forEach(function(node,index){ if(index >= 10){ kmmh.leaderboardlist.push(node.textContent); // add names to array } }); } GM_log("all names from "+ kmmh.topAmount +" page(s) of leaderboard ==> "+ kmmh.leaderboardlist); does anyone have any idea what could be causing this ?? EDIT: i know i had to write according to what he would see on his mod screen. so i asked him to copy paste source of pages and so on. and besides that, this part of the script is not depending on being a mod or not. i got everything else working for him. just this function still doesn't on neither of his pc's.

  • calling same function on different buttons not loaded yet

    - by Jordan Faust
    I can not get this to work for every button and I cannot find anything explaining why. I guessing it is something small that I am missing $(document).ready(function() { // delete the selected row from the database $(document).on('click', '#business-area-delete-button', { model: "BusinessArea" }, deleteRow); $(document).on('click', '#business-type-delete-button', { model: "BusinessType" }, deleteRow); $(document).on('click', '#client-delete-button', { model: "Client" }, deleteRow); $(document).on('click', '#client-type-delete-button', { model: "ClientType" }, deleteRow); $(document).on('click', '#communication-channel-type', { model: "CommunicationChannelType" }, deleteRow); $(document).on('click', '#parameter-type-delete-button', { model: "ParameterType" }, deleteRow); $(document).on('click', '#validation-method-delete-button', { model: "ValidationMethod" }, deleteRow); } the event function deleteRow(event){ $.ajax( { type:'POST', data: { id: $(".delete-row").attr("id") }, url:"/mysite/admin/delete" + event.data.model, success:function(data,textStatus){ $('#main-content').html(data); }, error:function(XMLHttpRequest,textStatus,errorThrown){ jQuery('#alerts').html(XMLHttpRequest.responseText); }, complete:function(XMLHttpRequest,textStatus){ placeAlerts() } } ); return false }; This works only for a the button with id validation-method-delete-button. I use document and not the button its self because the button is contained in a template that is loaded later via ajax. I have this working for a similar function that is selecting a row in a table however I am not attempting to pass data in that scenario.

  • ExtJS Close button on each tab in a Tabpanel

    The Extjs API site adds a new tab for each search you do. The tabs each have a red X on them to close the tab similar to what browsers have. Check it out here: I'd like to replicate this and it seems like something that would be built-in to the API, but cannot find it. Any ideas?
