I'm trying to make use of XMLHTTP object, but I've come across a problem. It seems that there is no way to create dynamic array of such XMLHTTP objects (to make several requests) and handle them properly. I was trying to use such code:
View 6 RepliesHw do I send arguments to an onreadystatefunction when calling a document via xmlhttprequest object. For example,
I want to do something like
function getDoc(url)
xmlhttp=new XMLHttpRequest();
xmlhttp.onreadystatechange=writeHTML(id);
xmlhttp.open("GET",url,true);
xmlhttp.send(null);
}
function writeHTML(id){
if (xmlhttp.readyState==4)
{
// if "OK"
if (xmlhttp.status==200)
{
document.getElementById(id).innerHTML = xmlhttp.responseText;
}
}
In firefox, i look through the DOM and its showing me that both xmlHttpRequest and ActiveXObject("Microsoft.XMLHTTP") are undefined.Also if one could check the ready state methods I used, I'm not 100% if they are correct eg. xhttp.onreadystatechange = loadBlurbs() and if null is the value for a failed loading procedure.lasty, can I do this processBlurbs() = getElementByTagName, and then, processBlurbs() { this.length, this.child etc. ? }
Code:
<script type="text/javascript" language="javascript">
var blurbdoc;
var blurbs;[code].......
every time a window is opened in our software , I built a function to get the win32 handle address for each object inside this window ,by its string name (this is something that remains unchanged). now,after opening the window in real time , and running the function, I have some value like this for example: 0x00b206d8. my question is , how cand I use this handle value in order to do some actions on this object- for example insert a value and etc... I need the correct syntax in order to do so ,

It looks as though MSFT expects the client to be running Windows and ActiveX and have certain DLLs installed; and Mozilla seems to have its own implementation of SOAP. Is it
possible to implement these protocols in pure client-side javascript?
So I know all about the caviats of the 'this' keyword when calling object functions from event listeners:
Code:
var foo = {bar: true, zoo: function() { return this.bar; }};
foo.zoo();
> true
a = foo.zoo;
a();
>
And I know that I can get around this by using an anonymous function so that 'this' is preserved in it's original context:
[Code]...
But then someone pointed out this article on memory leaks when using anonymous functions to call object methods because the anonymous function gets access to ALL variables in the enclosing environment and my not be properly disposed of by the garbage collector [URL] So that lead me to think about using a "3rd-person" approach to referencing object properties from within object methods.

Is there a way in Javascript or Jquery to return an array of all objects underneath a certain point, ie. the mouse position. Basically, I have a series of images which link to various web pages but I have a large semi transparent image positioned over the top of the other images. I want to find the href of the background image that the mouse pointer clicks over.
View 1 Replies View RelatedI am really hoping someone is willing to take the time to read this post and take a minute to take a look at my code. What is happening is there are some matches for a script I made and then an area for segments during an event. If you notice on the segment part of the form is that there is a dropdown that asks for where in the event that segment needs to go. With the Introduction or the different numbered matches. What I need to happen for a subArray I need it to take the introduction, all the matches, and all the segments and order them accordingly. With the introduction first, the matches in order based off there match number and then the segments in between the introduction or matches based off the user's input.[URL]..
View 7 Replies View RelatedI have the following array
var arraydata={NOT1NO:{ field1: 'NOT1NO',field2: 'DURcy',field3: 'valuta',field4: 'INF'},NOT2NO:{field1: 'NOT2NO',field2: 'DURcy',field3: 'valuta',field4: 'INF'}};
I easily access parts of the array like arraydata.NOT1NO.field1.
But if for some reason I try to access a part of the array that does not exist, like arraydata.NOT1NO.field22, the whole script stops to function. Is there a way to handle this? For instance:
if (arraydata.NOT1NO.field22 DOESNT EXIST) {do something} else {do something else};
I have tried .length, .inarray but not found a working solution.
I am currently working on building a library and having my functions(methods) within my library. I am having trouble find some code for JavaScript that can help me to do the following:
I need to give an array of objects and the name of a key, return the array sorted by the value of that key in each of the objects: "a" + [{a:2},{a:3},{a:1}] → [{a:1},{a:2},{a:3}]
I need to make a functions with this characteristics:
- params: an array of strings with the names of components in a page
(for example, some inputs)
- body: i need to assign to the property readOnly the value true for
all the objects in the array
Is it possible to create an array of objects? I require a two dimensional array of objects.

var carList = new Array();

var properties = new Array();

As they all have the same property set but with different values I thought I'd try creating a servo object, the create an array of servo's but I don't think I'm getting anywhere fast. Heres what I have

Once this is done and I've got all the servo objects created with their properties, I'm hoping to be able to search for all servo's with a set property i.e all servo's with servo.application = 1 would that be possible, if not I geuss I'd be wasting all our time trying to create classes I can't use the way I'd like.

Well let's say i have a bunch of div tags with name attribute 'hello'
<div name='hello'></div>
<div name='hello'></div>
<div name='hello'></div>
I want to use JavaScript so that i can look through the array of these div objects.
var helloDivs = document.getElementByName('hello');
var len = helloDivs.length;
.....
So, it works for all the recent version of browsers but not for IE6. There is still about a 10% market share who are still using IE6. What is the workaround for this browser support?
If i were to print the variable len in IE6 says that is 0 and if i print helloDivs, it says it is an object as if helloDivs is a variable that contains an object but not an array of objects.
I have a simple function that removes an object from an Array of objects using splice. As per documentation I've been reading, Array::splice returns the removed element(s) (in this case, it should be object(s)).
When this method is called I receive 2 alert messages I've added for debug purposes

I know that I can retrieve the values from a single object and place them in a <ul> with the following code :
$('document').ready(function(){
var employees = {

I have an array of objects that I would like to sort through and "join" objects that are the same. And if they are the same, I need to sum up the number value given for those two items. So I guess Im sorting through and maybe even recreating this array to get rid of duplicates while I tally quantities. see the screenshot of my array of objects to help understand better. The highlighted 'sPSPN' would indicate that it is a duplicate item and its 'fUnits' need to be totalled. in the end I would have a total of 3 objects, because 'sPSPN'= BT-221-44 would now be only one object with 'fUnits' = 35.

View 4 Replies View RelatedI am populating a ‘Select’ object with data from an Array, and I succeed in load the page with the required data on the ‘Select’ dropdown list. But when I see the source code generated (view-source code) from the browser there is no option on the ‘Select’, you can see this form the browser source code:

And I want that appears the options generated in order to be able to talk with server, because server is waiting for some value (1, 2, 3 or 4). Now when I submit the form the server don’t recognize the option (value) received. So maybe the source code generated should be: Code:
I have a set of functions that will transition/fade photos in and out as background images. Easy. But now I would like to run the same functions on a different html page with different photos (each different page represents a different JavaScript array).
I've been reading online on how jQuery methods can be called into functions. So my thought process is to create 2 methods (1 for the original images and the 2nd method for the other images).
So here is my base code which works...
$.landingpage = function() {
/*Enable background image cycles on landing page*/
var images=new Array('/image01.jpg','/image02.jpg');
var nextimage=0;
