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('....');
Here's one that I don't understand:
<script type="text/javascript">
fso = new ActiveXObject("Scripting.FileSystemObject");
myCollection = new Collection();
[code]....
During execution, I get a "Object not a collection" error when I try to pass "MyCollection" to the Enumerator function. What am I missing?
I have the following nested javascript collection (below) and I'm trying to access the information within the collection using prototype so I can properly style and layout the data.

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.

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 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'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:
View 3 Replies View RelatedI 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.

Tarray = document.Form1.children
for (var prop in Tarray)

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?
'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'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:
1) How could I make my mouse click on each url with timer between the first url and the second and so on and let's say time between the 1st url and scroll down to the second with timer of 3 second .
2) How to make also the mouse click on certain button on that website what is the command code for that.

I am trying some simple things with javascript and trying to use it in a object oriented way. However I am now facing a problem in which I can't access an object variable from an object method. I am using jQuery.
My code is as follows;
Code:
My problem is that the variable msg1 does not work when accessed from function called from the jQuery get function. I get the message undefined. Therefore I am wondering, is there a way how I can access msg1 of my object instance from the get function of jQuery?

I have two result. SelectableChildren: groupHead.nextAll(".SimpleButton") and SelectableChildren: groupHead.nextAll(".SimpleButton").next().children(".SimpleButton")
I would like to combine them into one object so that I can bind a handle to them in one loop. $.each(combineResult, function(index, object){ ... })
I have to make them in one, so that I can pass it around.

php page is echoing out:{"species":"Please select a species!"} I double checked the response from the php and firebug shows the same. On success alert is not alerting the JSON data instead, I'm receiving [object Object]. Why is that and how do what should I do to fix this?
I have the following code:
A = {
"value": "a",
};
B = A ;
B.value = "b";
alert (A.value); // => b
I expected A.value to be "a". how can I change values of a new object, without changing the parent-object?
I have come across an issue that only happens with IE.I have a custom save function that is designed to handle different ajax submits but I will simplify it for debugging. The issue is that once I make a submit everthing is fine at first. Then once I try to submit a second time it craps out. I am checking to see if there is an onsubmit function and then executing it like so before continuing. After the inital submit it is no longer found. When I alert the typeof document on the form it returns object but when I add the onsubmit it says object expected or object is null or undefined.
Code:
function secureBarSubmit(formId)
{
alert(typeof document.getElementById(formId)); // object always
alert(typeof document.getElementById(formId).onsubmit); // func first time then it is broken

Can assign a new function to a built-in object in Firefox:
But IE and Opera don't have a MouseEvent or HTMLElement that can be set up in the same way. Can you do this in IE or Opera, or just Firefox, and maybe Webkit?
every time I try and alert:
[ { number:0, secondnumber:0 }, { number:2, secondnumber:1 }, { number:1, secondnumber:2 } ]
it just shows [object object], [object object], [object object]. Why is this and what can I do to make the record be shown as it is above in an alert?
