Apr 26, 2010I am implementing an "auto complete search box" much like the one Google uses. If you notice on Google, if you type a letter and the drop down box appears with the predicted terms, you are able to navigate in and select from those terms using the arrow keys on your keyboard.
In my implementation, the drop down box is really just a DIV. It is separate from the search box. How do I replicate the Google behavior?
Setup A Textbox To Only Accept Specific Keys - Some Of The Function Keys Are Reading As The Same Values As Letters?
Oct 21, 2011I am trying to setup a textbox to only accept specific keys. The problem is, some of the Function keys are reading as the same values as letters.Ex.
112 - F1 - p
113 - F2 - q
114 - F3 - r[code]....
Is there another way to allow the function keys without enabling all matching letters as well?
Programming Function Keys (F1 - F2) Etc As Access Keys
Oct 18, 2009I am making a php/mysql epos system for my shop which will be run from a browser on my shop PC. I have large buttons which I would like to be able to 'click' by pressing something like the F-buttons at the top of the keyboard. Is it possible to override the standard button shortcuts for a web page. This is only going to be on my shop computer so accessibility is not a problem.

Conditional Shortcut (?:) Limitations?
Jul 20, 2005I just wrote the following script for something I'm working on:
<html>
<head>
<script type="text/javascript">
function KP_growit(subject,widthto,heightto) {
var target = document.getElementById(subject);
var tweenit = setInterval(grower,10);
function grower() {
(parseInt(target.style.width) < widthto)? target.style.width =
(parseInt(target.style.width) + 10) + "px";
(parseInt(target.style.height) < heightto)? target.style.height =
(parseInt(target.style.height) + 10) + "px";
(parseInt(target.style.width) == widthto && parseInt(target.style.height)
== heightto)? clearInterval(tweenit);
}
}
</script>
</head>
<body>
<div id="bluebox" style="position:absolute; left:173px; top:48px;
width:100px; height:80px; z-index:1; background-color:#99CCFF;"></div>
<div><a href="#" onClick="KP_growit('bluebox',400,300); return false;">grow
it</a></div>
</body>
</html>
I noticed that the script does not work because of the conditional
operators; however it DOES work when using the if...else format. Why is
this?

Keyboard "click" Events - Click Events Don't Seem To Fire If You Use Your Keyboard?
Jan 11, 2011It's pretty common to assign a click even to a <div> (or other tag), such as:
Code:
// JQuery
$(document).ready(function(){
$("div").click(function(){[code]....
Of course this event won't be accessible from the keyboard, which might be nice. Now if it where an <a> tag, you can do this:
Code:
$(document).ready(function(){
$("a").click(function(e){
alert("clicked");
e.preventDefault();
});
});
The click event will fire if you click the <a>, OR if you tab to it with your keyboard and hit Enter.My question is: is there a way to make elements other than <a> tags accessible in this way? I recently discovered if you define a tabindex on your div, such as <div tabindex="0">test</div>, you can tab to that div, but click events don't seem to fire if you use your keyboard. Are <a> tags the only tags that can work in this way?

Jul 28, 2005I'm writing some stuff where I wish to allow the cursor keys to control
elements in a page. This has not been a problem except with Safari
which appears to duplicate the keydown and keyup events which are fired
when the cursor keys are pressed. I.e. pressing and releasing say, K,
results in one keydown event followed by one keyup event. Press any of
the cursor keys results in two keydown events followed by two keyup
events.....

View 1 Replies View RelatedSorting Array Changes Keys?
Jan 26, 2010Firstly, apologies for my terrible JavaScript knowledge! I'm getting there! I have an array that is made up of the results of a few SQL queries. The queries return the record id and an integer. I need to sort the results of the queries by the integer. I am trying to store them in an array, using the record is as the key, then sorting the array. However, when I try to get the data out of the array, it has changed the key!
E.g.
Original results
[10605] = 141
[10744] = 116
[18835] = 166
[15304] = 166

Disable The Arrow Keys

I am learning JavaScript and am trying to write some script to pervent the page scrolling up and down while playing a game.For example.Guardian Rock uses the arrow keys to slide around, at the same time the page scrolls.[URL]
Here is the script I've tried to write to pervent the scrolling:

Using Objects As Object-keys?
Mar 17, 2011I was under the impression that I and object/associative array could have other objects as the keys for properties. That is, I should be able to set myObject[anotherObject] = 1. However, while this seems to work at first glance, any new object I set as a property key overwrites the first one.Here is the result of me testing in my Chrome console:
> var obj1 = new Object();
> var obj1.someProperty = "test"
"test"

Any Way To Detect Certain Keys OnKeyDown?
May 14, 2010What I need is something as such (based on previous thread): I have a textfield and I want to limit the input to only numbers, letters and caps.
So the code is:
<input onkeydown="return testChars(event)" type="text" .../>
function testChars(e){
var keyCode = e.keyCode;
if(e.shiftKey && keyCode==53){
return false;
} //block "%"
//HERE BLOCK EVERYTHING THATS NOT a Letter, caps and numbers
if ( (keyCode > 64 && keyCode < 91) ||(keyCode > 96 && keyCode < 123) )//Letters and Caps{
return true;
}else if ( keyCode > 47 && keyCode < 58 )//numbers{
return true;
}}
The problem however using the onkeydown is that I would need to cater for every single possibility of them using SHIFT+1=*, SHIFT+2, SHIFT+3 etc. which would take forever. And I cant block Shift because they might use it for capitalizing letters.
DOM Nodes As Keys To A Hash Table
Oct 28, 2005I want a hash table where DOM nodes are the keys. In Rhino, I can just
use the node objects directly as the keys, since the Java objects that
implement the DOM have handy toString() methods that return a unique
string for each object:
var a = {};
a[document] = ...;
a[document.documentElement] = ...;
This is obviously not portable. The portable solution, I guess, is to
come up with a hash function that works usefully on DOM nodes. Has
anyone thought about this problem and come up with a solution? With a
DOM 3 implementation I could even do something like:
var nodes = [];
var nextIndex = 1;
function getIndex(n) {
var i = n.getUserData("NodeIndex");
if (!i) {
i = nextIndex++;
n.setUserData("NodeIndex", i, null);
}
return i;
}
I want this to work with DOM 2 as well, though.
Any ideas?
Sorting A JSON Object On Different Keys?
May 29, 2009I am passing some equity option contract data from my PHP processing page to the UI. I am attempting to use the JSON response to populate a matrix. Along the far right column are the strike prices (22, 23, 24, 25, 26, etc) and along the top row are the expiration dates (Jun 2008, Jul 2008, Aug 2008, etc.). My struggle is how to match the option data to the correct strike and expiration date. An example of the JSON response is below:
Code:
{"calls":
[
{"row_id":119,"type":"call","expiration":"JUN 20, 2009","t1":22,"strike":"25.00","symbol":"JSAFE"},
{"row_id":127,"type":"call","expiration":"JUN 20, 2009","t1":22,"strike":"26.00","symbol":"JSAFI"},
[code]....
Would be a JSON returned object that has all the option prices for all the expirations as properties.

View 6 Replies View RelatedForce Js Array Keys As String() Not Int()
Jul 8, 2011Given a JavaScript "array" (ok, so really they are "objects" but it's being treated as an array...) in the format
HTML Code:
var patient_code = "0"
var header_id = "1";
var question_id = "1000";

HTML Code:
var fake_data_array = new Array();
fake_data_array["heading_information"] = new Array();
[Code]...
What's happening is, '1000', '1001', '1003', '1004' are being cast as integers, not strings, and it's "filling in" the first ~999 keys as 'undefined' so the length is returning something like 1005, not 7. I'm manually writing the arrays now, and will eventually be building this massive js array from a collection of existing PHP arrays. Is there a way to forcibly cast the values as strings?
