JQuery :: Prevent Action To Be Executed Before It Starts?
Apr 27, 2010
I am building a navigation which animates width on mouseover and revert it on mouseleave. That navigation also supports keypress/keydown actions, so it behaves like you hover with the mouse and additionally opens the submenu too. My problem is, when using the keydown (C) function, the menu opens up perfectly but when I mouseover then, it fires the 1. function and behaves like it should, it closes. I tried to stop that when just using keydown, but somehow I am stuck with it. Here comes the code:
if i append an link to the page the function preventDefault() dont work if i click on it anyone know how to prevent default action of an appended link?
I would like to get the function to find the value which is starts with given value in select Box. If jQuery does not support please let me know how to do using Java script.
I am using contains function but it returns all the matched values. Get the value value exactly starts with given value.Select box :
<select class="widthed1" name="dynamicitem" id="dynamicitem" multiple="multiple" size="7" > <!-- Will be added dynamically --> </select> $("#dynamicitem option:contains ('"+oldval+"')").attr("selected","selected"); -- It returns all the matched values.
I have a jquery slidedown effect which id triggeref onchange of dropdownBut the slide down effect starts a few seconds after the option is change.It delays
I have come across a very interesting problem that seems to be impossible to solve. Basically a web application that I am working on relies on a JavaScript function called go to change the input named view to the page name and submit the form. This form's type is post, so no values are included in the actual URL string. There is also another input called action and it's value is view. This is to tell the application that the user would like to view a page. The problem is because of the variables being of method post, page refreshes and back and forwards return errors because the post variables view and action aren't sent with the required data. To somewhat solve this problem I have created a feature that tells the application that if the post value page is empty then to try and get a GET var called page. To insert this var into the go javascript function I simple add this code
This line basically adds &page=[page] to the action of the form. The problem is, this code doesn't work because action is also the name of a form element. Referencing document.go.action refers to the input element named action and not to the form's action. Changing the named of the action input value is out of the question (Way to much changing of code, and possible room for error). What can I do to change the action of the form without referencing the input named action. Here is my go form and the JavaScript code:
I have a small problem with a form. After I click on a submit button a small animation starts, I would like to submit form after animation but nothing is working. I tried different methods and I also checked html for errors.
Code of function: $(document).ready(function(){ $("#button").click(function() { var productX = $("#first").offset().left; var productY = $("#first").offset().top; var basketX = $("#basket").offset().left+15; var basketY = $("#basket").offset().top+20; var gotoX = basketX - productX; var gotoY = basketY - productY; var newImageWidth = $("#first img").width() / 3; var newImageHeight = $("#first img").height() / 3; $("#first img") ..... .clone() .prependTo("#first") .css({'position' : 'absolute'}) .animate({opacity: 0.9}, 100 ) .animate({opacity: 0.6, marginLeft: gotoX, marginTop: gotoY, width: newImageWidth, height: newImageHeight}, 1200, function(){ $("#detailstext").submit(); //form id }); return false; }); }); I also tried $("form_id").post(0).submit(); but i got error: $("form_id").post is not a function
I have many inputs with name totalsum1,totalsum2,totalsum3 etc. I need to calculate number of inputs where name starts with "totalsum" and value is >0. I need to send result to another input with id="#rowtotal".My code:
$("#rowtotal").val(($("input[name^=totalsum]").val>0).size()); It's not working. Best RegardsRafa‚ Koszyk
i have following problem: When the user on my website presses a image link, I prevent the default behaviour, and toggle some table rows (show or hide them, depending on the the image src (closed.gif / opened.gif)). Since I got a lot of rows I run over and toggle, the function takes some time to process and the browser "hangs" in the meanwhile. Due to this I want to show the user that the operation is still in progress and want to change the image of the link to a load spinner until it is finished. So I thought that I just have to change the src URL of the image in advance and then start the function, but jQuery is ignoring the line and I don't know why? Here is the code I am using:
$("a[name='changeDisplayModeAll']").click(function(e) { e.preventDefault(); var newStatus; var imageSrc = $("img[name='imageChange']").attr('src');
I'm trying to implement the jQuery Cycle demo from 'mapsup dot com slash jquery'.It works, but my problem is that as the page loads all 3 images are shown briefly, one on top of the other. Once the page is fully loaded everything works OK. I've try removing all unnecessary CSS in an attempt to get it to load faster but it doesn't help. I'm running this on a Drupal site and have tried with caching enabled and disabled, but neither makes a difference, so I'm thinking the problem lies somewhere else. You can see the problem in action at 'cumbrevillas dot com slash landing slash test'.
i need to wrap the following code with (function($){ ... })(jQuery);But when i do so than the callbackfunction jsonpCallback will not be executed anymore.I hope someone can explain that to me...
// ( function($) {$(document).ready(function() { var error_container = $('#ul_demo_error')
I have a div with a click event that fires a show('slow')... however if the user clicks on the div multple times the animation plays that many times... is there a way to make it so that the click event is only executable once the animation is complete?.
I am experiencing some crazy stuff, at least crazy to me Both the 'if' and 'else' blocks (according to firebug) are being executed in the following anonymous function:
I created a dropdown menu using jquery. So when I hover over a button it slides down the menu. Now if I move the mouse out of the menu and bring it back in before it slides up(menu has a lot of items so there is enough time to bring the mouse back in on the menu)over the dropdown menu it starts a chain of slideDown() and slideUp() functions and it does not stop till I move the mouse of the menu or back on the button. Below is my jquery code:
Using ajax and jquery I'm calling a function on the server code that returns a javascript script that I need to assign to a div and get executed automatically when assigned.So far I couldn't do that, seems that the assigned script to the innerHTML of the div can'r be executed dynamically.Basically I'd like something like assign an alert('hello world') to the innerHTML and automatically see the pop up with the message.
I am new to all this but making good progress and having fun in the process. I have written quite a bit over recent weeks (including a few $.post / $.ajax calls) for various sites/applications but this one is really puzzling me. Here is a snippet of code that is causing me problems.
[Code]....
The problem is that execution jumps from line 2 to line 6 ... ignoring the function(data) and I am not sure why. I get the correct value of "team" arriving at the perl script .... and the perl writes the correct json back. I just can't think where else I need to look to debug this - as I said, I have done something similar 5-6 times over the last few weeks - all without a problem. So I am sure I am doing something stupid here.
Im having some troubles with some functions i launch in $(document).ready() to initialize the page. Then if i click on browser refresh everything goes fine... even more strange when i place alerts between then calls to these functions everything goes fine too... but the first time the page is loaded it seems that the functions are not executed at all.
I am a self thought web developer and am constantly having problems making sure that certain commands are finished executing before others are started. My most recent problem is trying to append a large amount of data, to a div, then sliding it down slowly. Since that data takes a while to append, the system is doing both at the same time, therefore not giving me the slide down effect. Here is the code:
Where "SomeDiv" is part of "cpage" and "data" is a large amount of images. I would like to execute line 1 and then all the other lines simultaneously. It is currently executing all of the simultaneously.
In the following code - Sometimes I get the correct image width and sometimes I get an image width that is ZERO. How do I make sure the loaded image attributes are there before I access them. Odd thing is if I click the same thumbnail twice I always get the width. If I click a thumbnail once I may get the width this time BUT when I refresh I may get a ZERO width.
Here is the code... $(document).ready(function() { $('#gallery a').click(function(evt) { evt.preventDefault(); var oldImage = $('#photoBox img'); // Selects the current image var newImage = new Image(); // Create a new image var imagePath = $(this).attr('href'); // get the path to the image file to load that was clicked - via its href attr name newImage.src = imagePath;// Set the newIamge.src to file name or Path if (newImage.width < 600) // If the width is less than 600 calculate a new margin to center the new image { var newMargin = (620 - newImage.width) / 2; var newHtml = $('<img src="' + imagePath + '">'); $('#photoBox').css('margin-left',newMargin); $('#photoBox').css('width',newImage.width); } else // assume width is 600 { var newHtml = $('<img src="' + imagePath + '">'); $('#photoBox').css('width',newImage.width); $('#photoBox').css('margin',5); } newHtml.hide(); // hide the newHtml before prepending will fade it in oldImage.hide(); // hide the old image $('#photoBox').prepend(newHtml); // prepend the newHtml newHtml.fadeIn(1000,function() { }); // now fade it in });});
