Accessing All Elements In ExtJs With A Common Id Name?
Dec 5, 2010
I have a problem in accessing all elements with a common id name in ExtJs. In fact, I have a couple of divs with id like:divmic+a number.
That is the code:
Code:
<div id="slideshow" >
<%
for i=0 to 660/23
for j=0 to 380/23
Response.Write "<div id=divmic" & i & j & "
[Code]...
If I try this code, what is inside of "each" instruction works, but if I want to access all those elements having id starts with "divmic", it doesn' work. Why it's happen that think and how to put all those elements into an array, in ExtJs ?

I have a JavaScript application which opens an ExtJS Window, containing an ExtJS TabPanel, which has a tab containing a Data Grid, showing approximately 900 - 1000 rows, each with 7 columns of text fields. The grid may also be filtered to show about 100 rows at a time. When the window opens, navigating to this tab can cause Firefox or Safari to spin/lock up for over 60 seconds...
This is Ext 2.2 I know it's very hard to say without code... but without seeing code, my question is: Should ExtJS be capable of displaying a grid of so much data? In trying to optimize should I be looking at my code, or is ExtJS itself the problem? Is anyone using ExtJs to display such large grids?

Firstly, I am aware of all the issues that are introduced with frame
pages - this was not my decision - it is just what I have to work
with...
I have a frame page that looks like this
-------------------
| topFrame |
-------------------
| navFrame |
-------------------
| ContentsFrame |
|------------------
Within the contents frame I have a NEW FRAME set which looks like this
--------------------
| | |
|treeFrm | frmDisp |
| | |
--------------------
I know that this is awful. I have a link in the contentsFrame. When I
move over that link, I need to get a layer that already exists in the
frmDisplay to become visible..

When are named elements written with script accessible to script?
<html><head><script type="text/javascript">
function ready() {
alert( document.getElementsByName("div").length );
}
</script></head>
<body onload="ready()">
<script type="text/javascript">
document.open();
document.writeln( "<div name="div"></div>" );
document.close();
</script>
</body></html>
IOW, why are there 0 elements named div at the time the <body>
element's onload handler is invoked? When can I retrieve this named
div from the document hierarchy?
This exercise is necessary since code I have written using the DOM
(that works) has to run on God-forsaken browsers such as IE 5.1 for
Mac whose support for the DOM is spotty at best.

I need to pull data from an iframe, everything is on my domain (no cross-domain issues). This is how the iframe is named.
Code: <iframe ID="search_frame" src="http://www.mysite.com/pnsearch.php"></iframe>
The iframe has a bunch of <span> elements in it. I need to access the innerHTML of the spans, to check for data and use the data elsewhere. Each span has an unique ID assigned to it. What would be the syntax to read this information? I've tried all sorts of document.frames["search_frame"].getElementById("ID").innerHTML variations to no avail.

However, I'm still wondering about my actual problem, which is that I need to initialize some arrays of named elements when the document is loaded so they can be used by other functions used as event handlers. What I have now is that every function that requires
these arrays checks to see whether they have been initialized, and if not initializes them. That seems to be a fairly ugly hack, and I'd like to use a better way if it exists. Does that make sense?

I'm trying to write a script for a website that reads from a database and makes a separate table for each entry in the database. Since the number of entries can change, I want to dynamically create a div for each one, which I can later hide or display based on user selection. However, when I try to access the dynamically created elements by their ID, they return null. Is what I'm trying to do here actually possible?
for(var i = 0; i < tables.length; i ++)
{
var newDiv = document.createElement("div");
newDiv.setAttribute("id", tables[i].name);
newDiv.setAttribute("name", tables[i].name);
newDiv.setAttribute("class", "hidden");
[Code]...

I'm having trouble accessing some Elements with jQuery after I created them and added them to the HTML. I want to add some Checkboxes to my Site as soon as the user clicks another Checkbox. That works just fine. But if the user clicks on one of these added checkboxes, i want an event to trigger, too. For starters, i just want to alert a message. But this doesnt happen.So, now I think the Elements are added properly to DOM tree. But still, when I click on one of the added input Elements, nothing happens.What am I doing wrong? How can i get jQuery to recognize the Elements I added?

One of the great annoyances I have with JavaScript is the lack of a good
consistent code library. Oh, there are a few code libraries scattered
around for doing various things. The problem is that each of them have
their own way of doing things. If we want to use more than one library
at a time, we often end up duplicating code and working with different
interfaces and practices that aren't necessarily compatible with each
other...
So... isn't it about time that we have a Common JavaScript Framework?
I'm thinking of a standardised code library, mostly (but not entirely)
built from the free code that is already out there. (I'm thinking of a
LGPL core with independantly licensed extensions.)
I know of a few very cool projects that aim to make JavaScript
development easier, more professional and to bridge the gap between
browsers and environments. (To name a few: DynAPI, DOMAPI, Sarissa,
13th parallels' library, netWindows, bindows, ActiveUI, f(m).) But I
don't know of any effort to bring all of these features into one common
framework. Can we do anything about this?
I'm not exactly proposing that we form a group to design and implement a
complete framework. I just think that, us, JavaScript developers should
talk to each other more and agree on a few things. Then, I imagine
being able to access this centralized, well designed library that is
ready for serious (and less serious) development and the dream goes on...
I have been working with JS (client and server) for some years now and
I'd like to bring more consistency to my code and spend less time
writing lower level code. So I may be writing this email more out of
wishful thinking than determined action. In any ways, I remain
interested to support any effort that would lead me to better, well
designed, programming.

Is there a way to place a code that will be executed any time any button is pressed or any hyperlink is clicked? I don't want to write or call this code on every button press. Something similar to java's base class functionality that is extended by child classes? In my project ,I have to manage users to access my app - and if a user is deleted and that same user is having app open in one of her browser windows and she performs any action,she should be redirected to login screen.
I am thinking of writing a code that will check if user exists in the db or not and then put it in javascript file at a common place so that it gets executed everytime user presses a button(or does any other action). I am using jquery and Direct Web remoting framework in my app.

Usually I have various JavaScript functions for common functionality on my pages (i.e. select all, export, etc.). Typically I will create a common.js file and place these functions within it. Is there any advantage to create a client side object which encapsulates this functionality such that I'd use something lik common.SelectAll() or something similar?
Not sure if there is a best practice peeps follow for this or not.
