JQuery :: Control The Sequence In Which Commands Are Executed?
Feb 18, 2011
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.
I trying to get numbers from <div>'s and use them in if() commands.I've got the number but the if() commands don't seem to be working.Here is the code I'm using:
Code: window.onload = showPhoto var pNum = 1; // global num
I had to do a break function and scripts in this portion. I am wondering if my format is correct here is what i made
Code: function createBar(partyType,percent){ // script element to create blank cells switch(partyType) { case "D": document.write("<td class='dem'></td>"); break; case "E": document.write("<td class='rep'></td>"); [Code]...
I am building an application that acts like a terminal command line. I want it to be fully interactable with the major keys on the keyboard. I am using Jquery as the base for the UI. There are two methods I am trying.
1. Using a textarea element.
2. Using a div element
If I use the textarea then I cannot utilise the tab button to create an indent as it move the focus away from the element. In addition to this, I want to use tool tips as the user type and I'm doubtful I could create this with a textarea.
If I use a div element then I cannot use the backspace button as it forces my browser to go back one in history.
I would also want to use the div tag to create the text field as tooltips will be easier to implement plus I could add line numbers using a list element placed within the div.
The problem I have is that the NETiom board will only accept single commands to the HTML server built in to the NETiom.
What I dould like to do is send the following commands, timed 500ms apart to switch off 4 outputs before initilising 1 of the 4 inputs.
The commands I need to send are : B01 B02 B03 B04 T01
These 5 commands switch off relays 1 2 3 4 beofre energising relay 1
OK the code I'm using currently is as follows which gives me the correct buttons and action upto the point of cancelling any of the first 4 relays before energising one.
The buttons I would like this action on are NE SE SW NW
Maybe the NE button calls a section of code which will send B01 pause B02 pause B03 pause etc etc
The error message says getElementById is null or not an object but it works fine with image ids and iframe ids. Can anyone tell me why this doesn't work?
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 (more-or-less) understand how animation queuing works when animating a single element, but what's the best practice or most efficient approach for animating 2 different elements in a sequence? callbacks on complete?this example animates #black and #white simultaneously, when what i'd like to do is animate #black, then #white:[code]
I created an internal application which shows a large list of tasks that will be completed on a server by a script. It will go through each in order and update a database with its status (E.x "Failed", "Good", "Errors: <msg>").What I am doing currently is pulling the ID's of these tasks from a database, and then passing them to JQ to .load() the actual content for each div.What I would like to do is figure out a way to have each div reload as something is happening to it. So, lets say the script fires on the server and begins to process task ID 1. I would like to figure out a good way to be able to instantiate reloading for each div, as it is being processed.I do not wish to reload the entire page, I would not like for all 200+ divs to be constantly refreshing.
I'm a jQuery novice to say the least so please bear with me here.I need to swap out some images in a timed sequence. I found a tutorial online which kind of does what I need. Here is the code:
I would like to show users 10 images (DIVs) on which they can click. Images will be numbers (0-9) and they have to click on correct sequence (example 4 6 3 2 2 7) and then click "submit" button. If they don't get correct sequence they get shown some message about wrong numbers, but if they get it wight they should get some message of success. I am searching for some similar jquery or ajax scripts and can't find anything. Has anyone seen this kind of samples anywhere or could share some code?Attachments unlock.jpgSize : 35.81 KB Download : 266
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 have four icons that I wish to face in when the page loads. When the first image is 25% faded, the second will fade in. When the second is 25% faded, the third will fade in. When the third is 25% faded, the fourth will fade in. Since I have never touched jQuery, with the exception of downloading plugins and using them, how should i best go about this?
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 });});
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:
