Is it possible to have an Array object (or an object derived from
Array) that is 'aware' of other code modifying its contents? I'd like
to have such an "onModify" function process an array everytime the []
operator is used to make a change. I know you can derive from Array,
but you cannot directly override the [] operator. Any way to make
this possible?
// possible definition of 'SpecialArray'
...
function OnModify()
{
// process the list
}
I'm writing a program that involves a network of interconnected nodes (or simply objects in my example below). It depends on being able to access properties of an object's linked objects (a bit oddly worded, sorry)...Problem is I'm not sure how to properly access those properties... see below please.
<script> //This is an example of a problem im having in my own code... //I want to access the name of the object within the links array wintin the object...
I'm building a navigation that is built heavily on jQuery. I have it working as needed except that when mousing over links to quickly it spikes the processor and the navigation hangs. By hangs i mean it stops working and even the links will not show rollover states. I thought it was just a matter of adding a stop() but this changed nothing.
On my test page you'll see a red box with a 0 in it at the top [URL] if you look at the jQuery, it says that on ever mouseout and in the "P" should increment. I set this up just to see if i could first get a response out of my mouse over. But Not even this basic thing is working.

I am building a shopping cart in Volusion. I've come really far and can find my way around HTML and CSS.But the template I am using has a zebra function that it uses on the shopping cart screen. The colors it is using are terrible, and I can't figure out how to change them.By zebra, I mean it picks every other row in a table and assigns a different background color. I am noticing in firebug that the div-ids of the items in the cart have div-ids taht are not listed in any of the CSS files in the theme.I figured out that this type of coding is usually done in JavaScripting. I tried editing that file in every logical way, and I can get no response out of it aside from my browser hanging. I even tried commenting out different sections.
I'm not sure if you are at all familiar with Volusion, but they provide absolutely no assistance and try very hard to make things as hard as possible so customers will be desperate for their design services. All support will say is, "we are prohibited from providing any coding information. Would you like me to transfer you to sales?" They routinely remove resources that were once helpful. Nice customer service.
I'm having trouble with an onchange event with a select box. No function is responding. I can alert text out for the onchange event but none of the functions I have called will work.
In the attached code the outcome always defaults to the first test, even if the condition is false. How would I alter the syntax so that both condtions are evalauted?
From a click event I'm calling a javascript function if the function is written in same page it is calling, but if I include function in different page(here in selectuser.js file)
I have a simple select list and all I need to do is to feed whatever option is selected into a textfield above it.This works fine in FF but IE doesn't even recognise the click.If you vist http:[url]....and go to the bottom of the page, you'll see the silver color background select list.The "type of event" text field above is supposed to recieve the text of the option set in the select list.I have experimented with 2 bits of code, as follows:
I am following an example of an array in http://www.faqs.org/docs/htmltut/im...famsupp_59.html. Here is a part of the code:
var rollOverArr=new Array(); function rollover(pageImageName) { if (! document.images) return; if (! rollOverArr[pageImageName]) return; if (! rollOverArr[pageImageName].outImg) {
I am encountering a problem where I have a window and there are three frames, one in the left, right and in the bottom. The bottom most frame has common submit buttons. There are several tabs in left frame. Each one loads a different form on the right frame. After fetching the contents of the form from user, I am validating the text fields in the form using onChange() event handler. After entering the text value in the textbox, if I press Submit directly, the "Submit" as well as the validation routine happens concurrently. Only at the end of validation, the field is marked as dirty. Now, if field is not marked dirty, the Submit function will close the window without actually submitting as nothing was changed. So when an invalid value is entered and the Submit is pressed directly, an alert pops up temporarily but the close() call from the parent frame immediately closes the alert window before user can respond. This problem does not occur in IE as in IE, unless the alert window is responded, the close() call cannot close the alert window. Code:
This does not give any error but the alert says "joker" instead of "king". Is there anything wrong with my code or is an Object something that just can not be used as a key.
If it is the latter can someone please suggest another way for me to do it? Can I use a concatenated String instead of an object? My only problem then is how would I extract the values from the String, does JavaScript have a tokenizer method like Java?
How do I explain this? I am grabbing several elements from my document and placing them in an array, using jQuery. When I test the Code: typeof this item, it returns as an Object, not an Array, which is problematic for IE. Firefox seems not to have an issue with Code: Object.length , but IE won't have any of that, so I need Code: Array.length or do I? In the end, I just want IE to know how many keys are in the Array/Object...
What I'm trying to do, I think, is to use elements of an array as a part of an object. Here's a lil' code snippet:
Code:
I'm trying to insert each of the elements of the katMusik-array into the checked-line, thus checking the checkboxes with those names. However, it doesn't seem to work.
I have a function were the input parameter can either be an string,array,dom node or NodeList (getElementsByTagName()) and I have somthing like this function which works great for what I want in every case except if the pNd is the NodeList at which point I end up with the nodeList in the first element of the array instead of acting like the array would.
function doSomething(pNd){ if(pNd.constructor != Array){pNd = new Array(pNd)} return pNd }
So my question is how is there any easy way to figure out if pNd is a NodeList ? When I use pNd.constructor on NodeList all I get is [object]
i'm an actionscript3 developer who is somewhat new to js/jquery and am struggling through creating a site using jquery.I would like to be able to use the show/hide/toggle methods to switch between content using a standard navigation list. basically, what I want to do is this:1. store list of 10 <divs> in array with the id set to w1_blog, w2_blog, etc2. list of 10 links with ids = w1_blog_a, w2_blog_a, etc.3. store references to divs and links in array/s4. add event listener to each link5. .click event calls function that loops through each blog entry and shows the one matching the link (w1, w2, etc) and hides all others.I could do this in 2 mins in as3 but I'm struggling with the js syntax, despite it being very close to as3. It should (I think) look something like this:
$(document).ready(function(){ var blogArr = new Array(); var blogLinkArr = new Array();
I got an php page who picks up data out of my data base and puts it ina multidimensinal array. That array is being encoded to Json$event = json_encode($super_array);Then i made an javasript get funtion to get that array to my mainpage.
function get(){ $.get("../position of my file/test.php", function(data){ alert (""+data);
I have an array but I'm not exactly sure how to finish the build using an if statement. I have 6 elements and need the build to load a different top image for each array that loads that matches the specific element. Here is what I have but it only shows the first top image no matter what:
