I've been working on a dynamic script using the DOM and wanted a routine that would parse out the element attribute collection. I came up with a routine that works in FireFox 1.5 and Opera 8, but it doesn't work in IE 6. Any ideas? Code:

what I need is set an image title with given index (1)withvalue of span with given index (1). I tried some laborations with gt(), index(), but there is no success.
I have a form wherein there are around 200-300 rows of homogenous
data, each having around 30 input fileds of its own.So totally, there
are more than 6000 input fields . Now, when the user submits this page,
i need to loop through the checkboxes and identify the ones that are
checked. I can't use the getElementsByName() since the checkbox names
are different. I'm using getElementsByTagName("input"). Because of the
huge amount of data, this method takes around 4-5 secs to evaluate
before submitting the form. Is there some way to get the collection of
checkboxes without having to loop through all the input fields?
I have a .net application that I am trying to add some javascript code
to for a client-side execution. What I want to do is resize all the
HTML text fields on my web form, but instead of writing a line for
each text box I would like to loop through a collection of controls
and resize the control if it is a text field. Is there a way to do
this in javascript? The function below is what I have been toying with
for the past couple of hours. Another idea was to use a css, but I
can't find an element for the text field.
function Test()
{
Tarray = new Object;
Tarray = document.Form1.children
for (var prop in Tarray)
{
//document.writeln(Tarray.toString);
var s;
s = prop
if (Left(s, 3) == "btn")
{
prop.height = "20px";
}
}
}
I have collection: var collection = $(input);
var i = 3;
Is there easier way to get third jquery object from collection. Currently I'm using method like
$(collection.get(i)) or $(collection[i])
But I think something like this could be more comfort:
example: collection.get(i).addClass('....');

I am a visiting researcher at a laboratory this summer and my
current task is investigating javascript obfuscation techniques. I am
trying to get a relatively large sample of website containing
javascript code so I can analyze it and determine if it is:
1) obfuscated
2) malicious
I have a fairly decent inference what the result will be, but it would
be nice to have statistics on my side. Having said that, I believe it
will be necessary to have a very large sample size to perform my
analysis.
Now for my question, does anyone know if there are any ways to utilize
a web browser or other component to automatically find javascript
samples? Google has not yielded any results, and the code search
merely searches repositories; not exactly what I need.
Short of rolling my own crawler, can anyone offer any suggestions that
will aid me in my task?
I have a structure of similar blocks
- all containig a clickable image
- each identified by a unique hidden index
I want to find the value of that index when clicking on the image The code is something like :
<div class="bloc">
<p class="enTete">
<img class="modif" src="monImage">
<input type="hidden" value="1" />
[Code].....
How can i write the selector to read the right index when one the image is selected ?
Somethig like : (The '?' means I dont find how to do !!!!)
$(' ? .modif').click(function() {
test = $(' ? .index').val();
alert(test);
});
How can I validate a collection of fields, instead of validating the whole form? I'm using asp.net which uses one form element, which I even don't use. I have a tab panel with on each tab a couple of fields. I only want to validate the fields on a tab.
View 3 Replies View Related'm having a very hard time making this work and be happy in both IE and Firefox. Basically, I'm setting a timeout to get an array of the form values if not present, or compare against if they are present, and if any change in values, submit the form to auto-save it.
below is my coding, basically I am using document.forms[thisformname].elements - but that gives me a lot of things that are NOT form fields and I just need to read input:text, input:checkboxk, input:radio, textarea, and select elements - nothing more. I'm open to any suggestions and some of you smart guys could probably write this in half the lines I did.
Code:
//auto-save coding
var autosaveTimelapse=0;
var autosaveTimeout=3; //every n seconds

I'm working on an Ajax library that I plan to use on several upcoming
projects. Everything seems to work just great...
Now I want to get into the finer aspects of checking things... How
much memory am I using, are my objects making themselves available for
garbage collection adequately, etc.
Are there tools you can recommend (especially for IE and Firefox) that
I can use to get this information?
I'm using .parent on a draggable table row and need to check the contents of every cell in a particular column in the table. $(ui.draggable.parents("table")[0]) This gives me the table.. how do I get say the collection of cells in column 2. I thought about something like this: $(ui.draggable.parents("table")[0](tr td[1]))
View 2 Replies View RelatedLet's say $pages is a collection containing all div elements that have an id of page1 or page2. From this, I wish now to select now only the page div (i.e page1 or page2) that contains a descendant with a class of 'A'. Tried lots of things, just can't get the format right.
View 5 Replies View RelatedI've written some functions that seem to be able to handle parallel AJAX requests. However, I am not sure if they would work under all circumstances.My idea was to create a separate object for each AJAX request in order to bind the right handler function to the appropriate .onreadystatechange. I have used an array to store references to the created objects so that they would not be garbage collected as long as needed (see the lines commented out below). I have noticed, however, that everything works nicely even if I don't save these references -- so, with these lines commented out.
My question basically is whether it is safe to do so, and what prevents these objects from being deleted by the garbage collector. As both the event and the handler function appear to be in the same object, I think it will not stop the garbage collector.
In my code, ajax_req() is called to make a request; it will create the new ajax_abs object whose constructor takes care of the rest.
// ajaxrequests=new Array();
function ajax_abs(method,page,str,dest,todo,myno){
function init(){
[code]....
Furthermore, is it possible to tell the interpreter after the request succeeds, that now it should garbage-collect the object?
I have small webBrowser1 and I have the 3 Buttons(Back, Forward,Go) also I have the ComboBox1 with the Items Collection of different website url using MSVB 2008 in C++.My question:

2) How to make also the mouse click on certain button on that website what is the command code for that.
i have found a possible bug in 1.4 but it's only in Internet Explorer 7 & 8.The following code does not work and completely ruins every peice of jquery on the page (that means everything inside $(document).ready and anyting else...
$("<div/>",{
id: 'tooltip-'+rand,
class: 'dock-tooltip',
[code]....
I cant see any syntax errors - i pulled the example from the 1.4 site. There is no trailing commas in the object notation and i really cant see any reason it would work in firefox and not IEx and more to the point not only not work in IEx but break any other jquery in the entire page....
I'm working with a large (and unweildy) ASP.NET application, and there is a lot of jQuery code that uses selectors like this:
[name=_aspnetControl$_withASubControl] And unfortunately, some selectors that also look like this:
[name^=_someAspNetControl$_radioButtonList].
In other words, the effort to remove the $ from the attribute selectors would be monumental. If it is possible to escape the $ symbols, I can do that easily enough, but unfortunately the situation right now means that I can't upgrade to jQuery 1.5.

I'll trying to tell the difference between the following three cases:
<img alt="text string" />
<img alt="" />
<img />
I can do this in Firefox with the following code, where elem is the
HTMLElement representing each image, but IE doesn't seem to
differentiate between empty string and undefined.
var alt = elem.getAttribute('alt');
alt = (alt) ? alt : ((alt===null) ? 'really_null' : "");
The desired output from running this code on the 3 tags above is:
text string
really_null
It seems like this should be really easy...but I'm having a really
difficult time trying to figure out what's going on...
$(document).ready(function() {
