The documentation for $.ajax() says that when the error callback is invoked, the error string may be null or one of "error", "abort", "timeout", "parseerror". So naturally, I assumed that if I were to call .abort() on the XHR that $.ajax() returns, the error string in the error callback would be "error". But that seems not to be the case. What I'm seeing, in jquery-1.4.4, is "error" as the error string. Has anyone else seen this problem? I'm using the most recent Firefox on MacOS X 10.6.
Normally I would abort my request this way: Code: var myRequest=new XMLHttpRequest; ... myRequest.abort(); But how would I abort my request when I'm making it using the Ajax Toolbox library? In their documentation I saw there is "aborted" which only tells me whether the request has been aborted or not so there must be a way to abort it.
I know there are the event handlers onBeforeUnload and onunload, which work great 90% of the time.But what would happen if a user who was in the system had a power cut? Would it then be down to the database that stores who is logged in to go through logging users out who havent done anything for a while?
I've got the following jquery code querying my server, but can't figure out how to Abort the query and reload the page immediately if someone clicks on <a> link. how to abort the current (all) ajax calls if someone clicks on <a> link??
This is my first time using jquery and Ive designed a small and simple fadein/out script that acts as a rollover on this navigation bar: [URL] Here is the code:
It works great. However, if a user quickly moves their mouse over the nav buttons and repeats the process, the rollover affect will fadein/ out over and over again until its completed the cycle the amount of times the user moved the mouse over the button back and forth. I wish to change this behaviour so that, somehow, the processing is aborted if it is noticed the mouse is not present after a fadeout is completed.
In PERL there is a 'die' function that stops execution of a program if certain conditions are not met.For example, a needed file is not found because it is miss typed.Is there a similar function for javascript?The code I would think would follow something like this:
Code: var FileName = ''; // might have expected to enter something like 'ExternalFile.js' from a Querystring
I'm playing around with forms and wrote a JavaScript function that loops through all form elements and displays every option in every select field with an alert for each one.
var els = form.elements; var l = els.length; for (var i=0; i<l; i++) // loop through all form elements { if (els[i].type.substring(0,6) == 'select') { var options = els[i].options; for (var j=0, len=options.length; j<len; j++) { alert(els[i].name + ' option ' + j + ' = "' + options[j].text + '"') }}}
In the form I am using this results in many alert boxes popping up.
This seems like a very, very basic question, but I've Googled it quite a bit and can not find an answer. Is there a way to manually abort that script (other than closing my browser) or do I have to keep clicking OK until the loop has run it's complete course?
I'm writing a small async webapp. in JavaScript and I'm using <script> element technique to load data. I'm usign <scriptbecause of cross domain restrictions with XmlRequest.
The problem is when I remove a element that is currently loading from DOM (with removeChild) Firefox still loads it and waits with other scripts.
What I want is to break this process and load a new data without waiting for old one.
I call a javascript function b from another function a.
in the function b at certain conditions i want to stop the javascript execution and i have did it by throwing an exception by using Throw New Error('Stopi').
I have a jquery-powered "start page" that checks your log in and if successfull it slides in a "menu" of new places to go. The problem is, if you click back from one of the new places, the original "start page" looks as if you never logged in. You have to reload the page. Not very intuitive and this website is for kids. Now I've tried setting form field values with server session variables, javascript variables, etc etc but they all get reset when you click back. I've tried the "onunload hack" which I don't fully understand, and then read a bit about the onhashchange event which is from what I gather only compatible with HTML5 browsers...is there no way to detect if the user is already logged in when they click the back button or am I not doing enough homework?
This function is getting called as it should. the line "if ($("lumode").attr('checked'))" is not detecting the state of the checkbox properly. It always returns false so mode never gets set to 'all'. (#lumodestate is a button I am using to test the function).
So, I'm new to jQuery, but have a pretty good understanding. Still, I've come across an issue that I'm not quite sure how to resolve. I'm using wordpress, and have a .swf inside of a div, "player." The player class has no height spec, as the height of the .swf is different depending on the page. What I need to do is detect the height of the .swf on each page, and then apply that number as padding-top to another class?
I was wondering if there is a way to detect when a page has completely finished rendering? Is there an event in the JQuery library or JavaScript in general to detect when a page has completely rendered. I'd like to get some timing information for how long it takes for a page to render. I'd to do this offline to see how much CPU performance affects web page rendering.
I am trying to change to change the background of a li element when its own class is changing i tried : $("ul#slide-nav li").each(function() { if ( $(this).hasClass("selected") ){ $(this).css("background-color","black"); }else{ $(this).css("background-color","gray"); }}); This seems to be working I think., but once the class change again it doesn't work.. how can it loop for ever?
Basically what i am trying to do is that i have a unordered list and basically destroys the new list and creates a new one. The problem is that each element of that list has a hover event method. After the new list is created, the hover event is not detected.
I'm trying to use JS to move the cursor from my user login text field to the password text field - I've put the onKeyPress() event in the user input tag but then I press the Tab key the cursor doesn't move -
function detect_tab_key() { var key_code = window.event.keyCode; if (key_code == 9) { document.forms[0].frm_password.focus(); document.forms[0].frm_password.select(); } }
I would to change the color of some td cells if there is text in it. Right now this code does the job, but it changes the color of evry table. I'd like to know a way to do this on one table in my page and not all of them.
var count='0'; var TDs=document.getElementsByTagName('td') var length=TDs.length; i='0';
Why is it that you need the return keyword? Where does the argument event come from?
I know it works, I just want to know why it works.
I've been looking at some refferences and can't seem to find an answer if someone could give me an explanation or point me to a website, that would be great.
I am trying to do something I thought would be simple in javascript, and I'm at a loss. First code is GOOD code, except that it does not account for the possibility that the button(s) in question do NOT exist. The second and third subsets are two of several attempts to do just that. Code:
I need to write a script that detects if a person has flash installed and if they do then do something, if not do something else.
I can do this no problem with javascript - except for the detecting flash part. I have no idea how to have a js detect flash - or even if its possible.
