JQuery :: Option To Get The Same Functionality As ".toggle" For A ".keydown" Event?
Sep 4, 2010
What I'm trying to do is display a menu on keydown, having it go away when the key is pressed again. Specifically I'm using the "M" key. Here's my code so far:
[Code]...
The highlighted section is what I want. I already know that this won't work, because I've tried it then re-read the description and realized that ".toggle" binds to the click function. That's fine, but I need the same functionality on a ".keydown" event.
I'm trying to get a keydown function to trigger an event... The same as the onclick event I currently have working. I got the buttons to work on keydown, but I cant get them to work just like the onclick. Trying to get them to do the same thing.
So I have an event handler for the KeyDown event in a Javascript file but for some reason it does not get called the first time a key is pressed. However, if a key is pressed or a mouse button clicked then the next time I press a key it does get called. Here is the relevant code:
........................... // Other stuff $(function()
I have a code for the keydown event: -when you press the UpArrow key the image moves up -when you press the DownArrow key the image moves down.....and so on But don't forget that this is under the keydown event...so when I keep pressing the UpArrow key the image moves up but when I release the key the image still moves up. I already put the code $('myImage').stop(); on my image on keyup event but this doesn't do anything. There is a code to clear my memory from pressed keys or something?
When I upgraded to jQuery 1.7.1 (from 1.5.x), I found that an exception was suddenly thrown on every keydown event on an INPUT type="text". I still get the exception when I remove my change and keyup events. Previously I bound to these elements with .live, but I have the same issue with the new .on, so I don't think this problem is even related to my bindings.
The exception is as follows (from the custom WebKit frame where my script runs):
This occurs on line 3255 of jquery-dev-1.7.1.js, which reads:
I did some poking around and found that handleObj.origType is "keydown". There is no jQuery.event.special["keydown"] defined, meaning that the first part of the expression evaluates to undefined (there is no such thing as {}.handle). The second part of the expression, handleObj.handler, evaluates to true. The entire expression therefore evaluates to true, which can't be applied as a function.
I am trying to use the jquery keydown event.I wan to fade in a div that is a form then when the user presses keycode 17 meaning control key this div and form will fade in at the center of the screen.here is the code I have:
This is in a php file and echoing the code. So the " " ignore it it's just saying to php that those are to be echoed as " " This code isn't working. I would press control key but no fade in occurs. I include this php file to all my websites webpages which are php files.
I have a parent element that registered to the keydown event.somewhere down the hierarchy I have a table and some buttons. It appears that after I press the buttons, I only get the keydown event in the parent after 3 key strokes.I put breakpoints and the event is simply not called.I'm guessing this is a focus issue, but couldn't make it work.
I am trying to handle keystrokes on a text input element, in the keydown event. I need to know what character is about to be inserted into the string. I am able to get it for almost all letters, numbers and symbols using a combination of event.shiftKey, event.charCode, and String.fromCharCode() and some hard-coded lookup tables. (i'm aware that this is probably not going to work on non-standard/non-american keyboard layouts)
Unfortunately I can't get the character for a few: question mark, angle brackets, underbar, colon, and a few others. They all have charCode of zero, and nothing else in the event indicates which is which. Other than waiting till the element's value has changed (i.e. the keyup or keypress event), what can I do to tell which key is pressed?
Page 55 of JQuery Novice to Ninja shows the following code. When the page is run you CLICK on the first paragraph and the animation is triggered BUT I do not see any CLICK EVENT in this script. Isn't the document.ready function the trigger? What am I missing?
I am having a problem getting the error container to clear out after I have fixed invalid inputs. I am using the invalidHandler option. When my form is invalid it shows a message of the number of errors (taken from the sample code) and shows the invalid messages. After I correct each error the corresponding message goes away but I am still left with the message of the number of errors.
Here is my setup. $("#aspnetForm").validate({ focusCleanup: true, onfocusout: false, onkeyup: false, submitHandler: function(form) { saveAnnouncement(); return false; }, invalidHandler: function(form, validator) { var errors = validator.numberOfInvalids(); if (errors) { var message = errors == 1 ? 'You missed 1 field. It has been highlighted.' : 'You missed ' + errors + ' fields. They have been highlighted.'; $("div.error span").html(message); .....
In my form a <select> with options I wrote $('#select option'). click(function () { myFunction(); }); Works fine in FF - IE8 works only for $('#select'). click(function () { myFunction(); });
But it is not at all the same thing, and myFunction is fired when as soon the select opens. And I want it is fired only when I click on an option (even if it is not a change !) I tried some other manners for the same result. The last one was to write the options as <options class="opt" value ='x'><option> and $('.opt').click(function () { myFunction(); }); Works fine in FF, but not in IE8.
This is the code I am using to test this. In FF and Op. When I click on an option in the select box, the alert pops up. In IE and Chrome, it doesn't seem to catch it at all. $('.clickopt').mousedown(function(){ alert("test"); });
I'm having a problem when i use IE (on FireFox it runs with no problems).I have a event on options inside a select, that i call then there's a click. It's this:
Could anyone shed some light on why this might not be working? Nothing happens when I press either the left or right key... Well, I have put an alert screen in there that does work - the problem is that I want the a#previous_link to be followed, but nothing happens!
I currently have 3 jQuery events assigned to the document keydown, keyup and click.
Here is my code:
var logkeydown = false; $(function(){ $(document).keydown(function(e){ var key; e?key=e.keyCode:key=event.keyCode;
[Code].....
They toggle the boolean value of whether the keyboard key 'e' is currently pressed. If so, when the user clicks any of the site, I have a Thickbox fading in. This works great in Firefox and Safari, but IE7 begins to fade in the Thickbox (btw, I slightly altered the thickbox code to fade it in/out) but halts half-fade until the 'e' key is released.
I have a slight problem in FF3.5 that unbind('keydown'); is not working properly.. $("#q").unbind('keydown'); $("#q").keydown(function(e){ var code = (e.keyCode ? e.keyCode : e.which); if(code==40 || code==38) { var totalResults=$("#quick-search-results li"); var selectedResults=$("#quick-search-results li.qs-selected"); if(code==40) { var nodeIndex=($("#quick-search-results li.qs-selected").length<=0) ? 0 : $("#quick-search-results").index('li.qs-selected'); alert(nodeIndex); }}}); // end keydown
The above code alerts once on first keydown (with the down arrow key [code==40]), twice on the second, three times on the third and so on.. it worked fine in FF3 but a recent upgrade to FF3.5 seems to have broken the functionality..
Im trying to develop an AJAX application which updates a <select> list with a series of <option> tags when the user makes an entry in a field.
Therefore, my ajax application needs to dynamically create <option> tags and append them to the <select> list on the form. I have got this working in all browsers. However, i do not know how to add an "onclick" event handler to each <option> tag that is dynamically created in my javascript code.
Code:
As you can see, i create an option javascript object for each new <option> tag and add it to the <select> list. This works. But how can i also add an "onclick" event handler in the javascript code?
I know how to fire a JavaScript event with the onsubmit code.What I was wondering if it's possible to have a different JavaScript code fire when one changes the value in a select option.For example, something like this:
The event which in the following keydown function code is not returning the correct key codes. I have checked this in Chrome using the developer tools and the console.log(e.which) statement in my code.
Im trying to add a class to an element when the down arrow is pressed using keydown but once you release the down arrow the class is removed from the element.Is this normal behaviour?
I'm trying to get some elements enabled when a user start typing in a input field but without success. I try this codes:
$('#keyword').focus(function() { alert('Handler for .focus() called.'); }); $('#keyword').keypress(function() {
[Code]....
But none of them works. Just try in this page [URL] and start typing in "Buscar" (spanish) or "Search" (if you change to English) input and see that nothing happen and I don't know why. Note that I wrote alert() just for see if it works or not.
