jQuery > reset popup window 's x and y relative to icon that launched the window

- by Scott B

I have a jQuery jPicker colorpicker that is bound to an input text field and opens onclick of a small picker.gif icon. The problem I'm having is that (1) The colorpicker that opens does not appear to be positioned according to the x/y position of the picker.gif (it opens far away from the click point) and (2) The colorpicker does not seem to be aware of the viewport's scroll position (the top of the colorpicker is partially hidden at the top of the window). I'd like to use jQuery to reposition the colorpalette (1) Based on the x/y position of the input that its bound to and (2) reset it's top position based on the viewport's visible Y position. Here is the script where I am creating a new jPicker and binding it to my input text fields for header and sidebar... $('#myHeaderColor').jPicker ( {}, function(color) { $(this).val(color.get_Hex()); }, function(color) { $(this).val(color.get_Hex()); } ); $('#mySidebarColor').jPicker ( {}, function(color) { $(this).val(color.get_Hex()); }, function(color) { $(this).val(color.get_Hex()); } );

Display loading while webservice is running

- by poseid

On the initial request to a page, I trigger a webservice and want to display a loading message. When the page has finished loading, I want to remove the waiting message from screen, but display it again when a change event in a checkbox triggers an Ajax call with another loading message. This code is not behaving to the given spec: $(document).ready( $(function() { $('#loadingDiv').hide(); $('#productsDropDown') .change(function() { var prodValue = $(this).val(); $('#proddate').load('getpdate.php', {prod: prodValue }); }); $('#loadingDiv') .ajaxStart(function() { $(this).show(); }) .ajaxStop(function() { $(this).hide(); }) ; }); ); what am I doing wrong?

JQuery and PHP validation problem?

- by DuH

I want to do the validation on my PHP side and then have my JQuery code display your changes have been saved when the submit button is clicked but the JQuery code states that the changes have been saved even when the validation fails. How can i fix this so that PHP can do the validation and then JQuery can do its thing when PHP has finished its validation? Here is my Jquery code. $(function() { $('#changes-saved').hide(); $('.save-button').click(function() { $.post($('#contact-form').attr('action'), $('#contact-form').serialize(), function(html) { $('div.contact-info-form').html(html); $('#changes-saved').hide(); $('#changes-saved').html('Your changes have been saved!').fadeIn(4000).show(); }); $('a').click(function () { $('#changes-saved').empty(); $('#changes-saved').hide(); }); return false; // prevent normal submit }); });

onPageLoad is not working properly in Firefox Extension Development

- by Tharaka Deshan

I am new to Firefox Extension Development and doing my 1st program. Simply I needed to pop up a alert once it loaded the page. My code was like this: var myExtension = { init: function() { if(gBrowser) gBrowser.addEventListener("DOMContentLoaded", this.onPageLoad, false); }, onPageLoad: function(aEvent) { alert("Loaded"); } } window.addEventListener("load", function load(event){ window.removeEventListener("load", load, false); myExtension.init(); },false); But I am getting the alert box for couple of times. Then I found about "#document" and then I added a IF condition: onPageLoad: function(aEvent) { if (aEvent.originalTarget.nodeName == '#document') { alert("Loaded"); } } Unfortunately still I am getting the same. Please advise me on this.

Calling back a functions value

- by Jason Kelly

I need your help, I cannot, for the life of me, figure this out. I've had my head wrapped around it only to no avail. Ideally, i'd like to setup two functions. 1 function: select_date() to interact with the user to select a date from the jQuery Date picker. If the dialog is closed then return as null. Then a second function: test() to check wether or not a date was picked/selected.' Here's my delema, when the function test() is executed, an alert box pops up and says "undefined" which means, I never get to select a date and it always being "undefined" I dont see what I am doing wrong here and everything seems logical to me. <!DOCTYPE html> <html> <head> <link href="http://ajax.googleapis.com/ajax/libs/jqueryui/1.8.21/themes/base/jquery-ui.css" rel="stylesheet" type="text/css"/> <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.js"></script> <script src="http://ajax.googleapis.com/ajax/libs/jqueryui/1.8.21/jquery-ui.js"></script> <script type="text/javascript"> function select_date() { var sdate $('#dd').dialog({ autoOpen: true, modal: true, overlay: { opacity: 0.5, background: 'black' }, title: "title", height: 265, width: 235, draggable: false, resizable: false }); $('#d1').datepicker({ onSelect: function () { $("#dd").dialog("close"); } }); return sdate } function test() { var x = select_date() alert(x) } </script> <style type="text/css"> #d1 {font-size:64%;} </style> </head> <body> <div id="dd"> <div id="d1"> </div> </div> <a href="javascript:test()">test</a> </body> </html>

What is the best practice for including jQuery ext functions?

- by Metropolis

Hey everyone, Currently I have a file that I named JQuery.ext.js which I am including in all of my pages. Inside this file I have numerous functions that do things like the following, (function($) { /** * Checks to see is the value inside ele is blank * @param message string The message that needs to be displayed if the element is blank * @return bool */ $.fn.isEmpty = function(message) { var b_IsEmpty = false; //Loop through all elements this.each(function() { //Check to see if an empty value is found if($(this).val().length <= 0) { //If message is not blank if(message) { alert(message); $(this).focus().select(); } b_IsEmpty = true; return false; } return true; }); //Return false if the evaluation failed, otherwise return the jquery object so we can reuse it return (b_IsEmpty) ? true : false; }; /** * Checks to see if the value inside ele is numbers only * @param message string The message that needs to be displayed if the element is not numeric * @return bool */ $.fn.isNumeric = function(message) { var expression = /^[0-9]+$/; var b_IsNumeric = true; //Loop through elements checking each one this.each( function() { //Check to see if this value is not numeric if(!$(this).val().match(expression) && $(this).val().length > 0) { //If message is not blank if(message) { alert(message); $(this).focus().select(); } b_IsNumeric = false; } return b_IsNumeric; }); return b_IsNumeric; }; })(jQuery); Is there another way to do this? or is this the way most people do it? Thanks for any help, Metropolis

Using deprecated binders and C++0x lambdas

- by Sumant

C++0x has deprecated the use of old binders such as bind1st and bind2nd in favor of generic std::bind. C++0x lambdas bind nicely with std::bind but they don't bind with classic bind1st and bind2nd because by default lambdas don't have nested typedefs such as argument_type, first_argument_type, second_argument_type, and result_type. So I thought std::function can serve as a standard way to bind lambdas to the old binders because it exposes the necessary typedefs. However, using std::function is hard to use in this context because it forces you to spell out the function-type while instantiating it. auto bound = std::bind1st(std::function<int (int, int)>([](int i, int j){ return i < j; }), 10); // hard to use auto bound = std::bind1st(std::make_function([](int i, int j){ return i < j; }), 10); // nice to have but does not compile. I could not find a convenient object generator for std::function. Something like std::make_fuction would be nice to have. Does such a thing exist? If not, is there any other better way of binding lamdas to the classic binders?

I have a PL/SQL function which creates a new temporary table. For creating the table I use execute immediate.

Javascript & jquery : Unable to increment within a form

- by Daniyal

I got a simple increment function like this: $(function(){ $("#inc").click(function(){ var value = parseInt($(":text[name='ice_id']").val()) + 1; $(":text[name='ice_id']").val(value); }); $("#dec").click(function(){ var value = parseInt($(":text[name='ice_id']").val()) - 1; $(":text[name='ice_id']").val(value); }); }); the ice_id text field is embedded within a form <form id="masterSubmit" name="masterSubmit" action="" method="post"> <td><input id="ice_id" type="text" name="ice_id" size="16" maxlength="15"></td> </form> When I try now to increment , it successfully increments a number, but shows the following weird behavior: It 'refreshes' the site, so that the content of the text field is gone. This behavior disappears, if I comment out the form tags ...unfortunately the form tags are required for an AJAX-submit. Are there any ways to avoid this problem? Thanks in advance for any hints and best regards Daniyal

[JS] How to manipulate a PHP Array in javascript?

- by rasouza

I have an Array in PHP which contains data from database. And it prints out also as a table in the same page which has an AJAX delete function. Trying to explain better The array contains debt sums related to many people, it is the application's main function. In the same page, there is a table containing every debt record related to the array, which can be deleted or edited using AJAX. I have coded the part of deleting the record and removing the TR entry, but it's not enough: I'd like to change also the debt sum using AJAX which is an PHP Array. What I have I have the JS function which removes the TR when the delete button is clicked // TR Fading when deleted $('.delete') .click(function() { $.ajax({ type: 'GET', url: 'history/delete/id/'+$(this).attr('id') }); $(this).parent().parent().fadeOut(); return false; }); and I have the PHP array (image)

As expected, the above code doesn't work. How do I do something like pattern matching, but for the function it creates? Thanks

Jquery: fade menu out when clicking on anything EXCEPT the menu itself, short piece of code.

- by ExodusNicholas

.saf_search is a button, when it's clicked, the menu .lisearch fades in, when you click anywhere on the page EXCEPT for on the menu .lisearch, then it should fade out(that's how it's SUPPOSED to work) Does anyone know why this isn't working? It fades in, and the first time i click anywhere on the page it fades out, but the second time i try to fade in the menu, it will quickly fade out again without me clicking the document. i think this has to do with .one, but i had it working before my hard drive crashed, and now i can't figure out how to get it working again... $('.saf_search').click(function() { $('.lisearch').fadeIn(200); }); $(document).click(function(){ jQuery(".lisearch").click(function(){ return false; }); jQuery(document).one("click", function() { jQuery(".lisearch").fadeOut(); }); });

Dynamic Select boxes page load

- by Chris

Hello, I have a dynamic chained select box that I am attempting to show the value of on a page load. In my chained select box, it will default to the first option within the select box on page load, could anyone provide assitance? I stumbled upon this thread, but I can't seem to translate what they are doing with that answer to my language of CF. Dynamic chained drop downs on page refresh Here is the JS script I am using. function dynamicSelect(id1, id2) { // Feature test to see if there is enough W3C DOM support if (document.getElementById && document.getElementsByTagName) { // Obtain references to both select boxes var sel1 = document.getElementById(id1); var sel2 = document.getElementById(id2); // Clone the dynamic select box var clone = sel2.cloneNode(true); // Obtain references to all cloned options var clonedOptions = clone.getElementsByTagName("option"); // Onload init: call a generic function to display the related options in the dynamic select box refreshDynamicSelectOptions(sel1, sel2, clonedOptions); // Onchange of the main select box: call a generic function to display the related options in the dynamic select box sel1.onchange = function() { refreshDynamicSelectOptions(sel1, sel2, clonedOptions); } } } function refreshDynamicSelectOptions(sel1, sel2, clonedOptions) { // Delete all options of the dynamic select box while (sel2.options.length) { sel2.remove(0); } // Create regular expression objects for "select" and the value of the selected option of the main select box as class names var pattern1 = /( |^)(select)( |$)/; var pattern2 = new RegExp("( |^)(" + sel1.options[sel1.selectedIndex].value + ")( |$)"); // Iterate through all cloned options for (var i = 0; i < clonedOptions.length; i++) { // If the classname of a cloned option either equals "select" or equals the value of the selected option of the main select box if (clonedOptions[i].className.match(pattern1) || clonedOptions[i].className.match(pattern2)) { // Clone the option from the hidden option pool and append it to the dynamic select box sel2.appendChild(clonedOptions[i].cloneNode(true)); } } } Thanks so much for any assistance

lapply slower than for-loop when used for a BiomaRt query. Is that expected?

- by ptocquin

I would like to query a database using BiomaRt package. I have loci and want to retrieve some related information, let say description. I first try to use lapply but was surprise by the time needed for the task to be performed. I thus tried a more basic for-loop and get a faster result. Is that expected or is something wrong with my code or with my understanding of apply ? I read other posts dealing with *apply vs for-loop performance (Here, for example) and I was aware that improved performance should not be expected but I don't understand why performance here is actually lower. Here is a reproducible example. 1) Loading the library and selecting the database : library("biomaRt") athaliana <- useMart("plants_mart_14") athaliana <- useDataset("athaliana_eg_gene",mart=athaliana) 2) Querying the database : loci <- c("at1g01300", "at1g01800", "at1g01900", "at1g02335", "at1g02790", "at1g03220", "at1g03230", "at1g04040", "at1g04110", "at1g05240" ) I create a function for the use in lapply : foo <- function(loci) { getBM("description","tair_locus",loci,athaliana) } When I use this function on the first element : > system.time(foo(cwp_loci[1])) utilisateur système écoulé 0.020 0.004 1.599 When I use lapply to retrieve the data for all values : > system.time(lapply(loci, foo)) utilisateur système écoulé 0.220 0.000 16.376 I then created a new function, adding a for-loop : foo2 <- function(loci) { for (i in loci) { getBM("description","tair_locus",loci[i],athaliana) } } Here is the result : > system.time(foo2(loci)) utilisateur système écoulé 0.204 0.004 10.919 Of course, this will be applied to a big list of loci, so the best performing option is needed. I thank you for assistance. EDIT Following recommendation of @MartinMorgan Simply passing the vector loci to getBM greatly improves the query efficiency. Simpler is better. > system.time(lapply(loci, foo)) utilisateur système écoulé 0.236 0.024 110.512 > system.time(foo2(loci)) utilisateur système écoulé 0.208 0.040 116.099 > system.time(foo(loci)) utilisateur système écoulé 0.028 0.000 6.193

Python 3: Recursivley find if number is even

- by pythonhack

I am writing a program that must find if a number is even or not. It needs to follow this template. I can get it to find if a number is even or not recursively (call function and subtract 2, base case zero), but I am having a hard time following this template, based on how the isEven function is called in the main function. Any help would be greatly appreciated. Write a recursive function called isEven that finds whether a number is even or not: def isEven() #recursivley determine whether number is even or not def main(): number=int(input(“Enter a number : “)) if (isEven(number)): print(“Number is even”) else: print(“Number is not even”) main() Thank you! Appreciate it.

Need of optimized code for hide and show div in jQuery

Hello, I have a div: <div id="p1" class="img-projects" style="margin-left:0;"> <a href="project1.php"> <img src="image1.png"/></a> <div id="p1" class="project-title">Bar Crawler</div> </div> On mouse-over I want to add an image with opacity and make the project-title shown. So I use this code: <script type="text/javascript"> $(function() { $('.project-title').hide(); $('#p1.img-projects img').mouseover( function() { $(this).stop().animate({ opacity: 0.3 }, 800); $('#p1.project-title').fadeIn(500); }); $('#p1.img-projects img').mouseout( function() { $(this).stop().animate({ opacity: 1.0 }, 800); $('#p1.project-title').fadeOut(); }); $('#p2.img-projects img').mouseover( function() { $(this).stop().animate({ opacity: 0.3 }, 800); $('#p2.project-title').fadeIn(500); }); $('#p2.img-projects img').mouseout( function() { $(this).stop().animate({ opacity: 1.0 }, 800); $('#p2.project-title').fadeOut(); }); }); </script> The code works fine but does anyone know a way to optimize my code?

HeadJS ready for both document and script

- by Yashua

Current code: head.ready(function() { console.log($('.thing a').val()); }); It will sometimes fail with error that $ is not ready. I have loaded jquuery earlier with the label 'jquery'. Neither of these work: head.ready(document, function() { console.log($('.thing a').val()); }); head.ready('jquery', function() { console.log($('.thing a').val()); }); I would like to not do this if possible: head.ready(document, function() { head.ready('jquery', function() { console.log($('.thing a').val()); }); }); And also avoid refactoring current code to place that snippet at bottom of body though that I think may be the solution. Is it possible with HeadJS to define a ready call() using head.ready(), that is not placed at the bottom, that will wait for both a labeled script and the DOM to be loaded? UPDATE: the nested script doesn't actually work. I think the inner one erases/superseds the other :(

When I use return and call the variable within another functions I get a NameError. Thanks, S :-)

Initializing own plugins

- by jgauffin

I've written a few jquery plugins for my client. I want to write a function which would initialize each plugin which have been loaded. Example: <script src="/Scripts/jquery.plugin1.min.js")" type="text/javascript"></script> <script src="/Scripts/jquery.plugin2.min.js")" type="text/javascript"></script> <script src="/Scripts/jquery.initializer.min.js")" type="text/javascript"></script> Here I've loaded plugin1 and plugin2. Plugin1 should be attached to all links with class name 'ajax' and plugin2 to all divs with class name 'test2': $('document').ready(function(){ $('a.ajax').plugin1(); $('div.test2').plugin2(); } I know that I can use jQuery().pluginName to check if a plugin exists. But I want to have a leaner way. Can all loaded plugins register a initialize function in an array or something like that which I in document.ready can iterate through and invoke? like: //in plugin1.js myCustomPlugins['plugin1'] = function() { $('a.ajax').plugin1(); }; // and in the initializer script: myCustomPlugins.each(function() { this(); }; Guess it all boiled down to three questions: How do I use a jquery "global" array? How do I iterate through that array to invoke registered methods Are there a better approach?
