Push() With A 2d Array?

May 28, 2007

I have a 2d array that I created like such:

var images = new Array(50);
for(var i=0;i<=51;i++)
{
    images[i]=new Array(2);
}

Now I would like to push values into this array, but I can't get the proper syntax to work. How would I for example convert these statements:

JavaScript Code:
images[1][0]='a'
images[1][1]='b'
images[1][2]='c'

into a push statement (regardless of position pushed into array)?

Array Using Push And Pop ?

Dec 17, 2010

I have an array question. I think that you'll have to run the script in your browser to see the results. The below array separates ages but I get stuck on how it does this when I get to line 6 and beyond. Line six reads "if (tempAge <21) minors.push(tempAge);"

I only understand that the pop method takes the number 19 off of the ages array. So if this is so then I think that line 6 reads that if 19 is equal to or less than 21 do something, but I don't know what it does after that, please help me understand how it works.

Push Values From One Array To Another?

Mar 29, 2011

Let's say i have two arrays:

var array1 = ["1","2","3"];

var finalArray = [];

and I want to dump the values of array1 into finalArray several times to end up with the value of finalArray being:

"1","2","3","1","2","3","1","2","3"

What would be the easiest way to dump the values into the other without making it multidimensional?

Array.prototype.push = Function() {

I found this code on Internet:

<script type="text/javascript">

Array.prototype.push = function() {
var n = this.length >>> 0;
for (var i = 0; i < arguments.length; i++) {
this[n] = arguments[i];
n = n + 1 >>> 0;
}
this.length = n;
return n;
};

</script>

Question 1: How to call this function?
Question 2: When I delete >>> 0, what I lose? ( >>>0 &#305; sildi&#287;im zaman, ne kaybederim?)

Array.Push Stopping Conditional Code

Nov 12, 2009

I am basically just practicing with javascript (Just started a few days ago) and wanted to create an array that pretty much checked a form for errors, listed errors, then spewed them out in the end. I am sure there is source code for something like this, but I wanted to just do this out of practice, as I have done this before in PHP. I am basically making a function with a bunch of if statements and if any of them pop up I try to PUSH a string into the array. Now, it has worked, somewhat and sometimes. But then it just plain stopped working. I played with the code for a while, placing alerts in parts of the function and found that it WAS the push code that stopped it from running completely.

Javascript To Push IE Window To Front

Jul 23, 2005

We've got a CDROM with a Flash Projector movie on it. Within the
Flash projector (which is already burned on CDROM...can't change it),
we have the typical getURL fuctions to open a Web browser and browse a
link. This works fine when there isn't a browser window already open:
the link opens in the FOREGROUND, infront of our Flash Projector.

However, now we've got a problem since after we've burned the CDROM,
if a user has a Web browser open already, and clicks a link within the
Projector, the new window does not come to the front...it simply stays
behind the full-screen projector.

So, we've tried putting an onLoad="window.focus;" tag in our BODY tag
on the web pages our Project is linking to, and that actually worked
at first (the pages are ASP Classic). However, they're not working
anymore. We're really not sure why.

When we load that page, quickly flip to another via ALT-TAB, the first
page DOES come forward. However, it doesn't seem to come infront of
another application. So, if we hit reload for the above page, then
quiclkly ALT-TAB to MS Word, the page will not force itself infront of
Word.

JQuery :: Drawer Menu - Does Not Push Content

Jun 24, 2009

I'm fairly new to Jquery - I'm more of a backend PHp programmer but I just started picking up Jquery and I really like the features it adds to the frontend. I was wondering if someone could point me in the right direction for a Jquery drawer like menu that does not push the content of the site down.[URL]...

Thats an example of what I want, however as you can tell it pushes the website down when it opens and then collapses when it closes. What I want is for someone to click the drawer handle and have it slide down (the graphic), revealing a login box. This would need to float above the content that is already there, so I assume a z-index or something would do this. If anyone knows where I can find a script like that please let me know I have been looking.

On a side note if you don't know where I can find that if you could give me pointers on how to convert the menu I linked, I plan to pickup a JQuery book this weekend to start reading up on it more but anything to help me get this project moving would be great.

JQuery :: Menu To Push Content Down The Page?

Aug 2, 2011

I'm developing a menu that uses jQuery. I'm very new to this and I'm wanting to do something but haven't a clue how.[URL].. What I'm wanting to do is have the menu push the content down the page when it expands. ie: so that it doesn't just float over the top of the images as it does presently. I suppose when the menu collapses it should allow the content to move back up the page. Is this possible?

JQuery :: SlideDown() And SlideUp() Be Used To Pull Or Push An Element?

Jun 29, 2011

I am using slideDown() and slideUp() in an accordian style menu to reveal and conceal sections of the menu. By default it seems that these methods will open and close from the top or bottom respectively.

Is there a way to use the methods so that the bottom of the element seems to be being pulled down or pushed up rather than simply revealed or concealed? There are styling elements added dynamically to wrap each heading and section which is why they have containers and why the iteration through parents() is necessary.

JQuery :: Prevent Multiple AJAX Calls From Button/link Push?

Sep 28, 2010

I am working on a project that relies heavily on AJAX calls, they are done in dozens of places. There are a number of places where I would want to prevent the user from submitting information multiple times (form submissions etc ). I am trying to think of the best way to accomplish this.

I could simply disable the element that starts the AJAX call upon the first click and re-enable it upon completion of the call. I have also seen examples of developers using a class to handle ajax calls that store an identifier for the call and if it is in progress any new calls with the same identifier will be ignored.

JQuery :: Submenu From Array - Function ToggleOptions Takes 3 Variables - Target - Array - State

Feb 15, 2011

I am trying to understand somecode. I don't think I am understanding everything correctly. Can someone confirm or add to my understanding?

Here is the code, below is my explanation:

- CODE 1 - is saying if the the class subnav_dd is called on an anchor tag on a li, then make the function in the if statement "live". (Live in a sense binds the function to the condition, but unlike bind it allows the condition to be used more then once. ) So if the class subnav_dd is the parent, and has a class of .dis then prevent anything below it from firing. CSS - If code 1 is true, then I will only get the first li to fire, the remaining ones will not.

- CODE 2 - This one is a little tricky. Function ToggleOptions takes 3 variables (target, array, state). The condition is if the div subnav + target have siblings, then check to see how many siblings are there. Put the amount of siblings into an array, then check the state of each sibling. I don't completely the rest of it.

I think if the div subnav is called and something is found in the array then the class dis is either added or removed. Then what? I don't understand why I still need the else that adds a class to #subnav_ +.target

Comparing Array Values To Select Unique Array Elements?

Prototype To Sort An Associative Array On The Array Key (in Ascending Order)

Sep 1, 2010

I am building a customised javascript prototype to sort an associative array on the array key (in ascending order). Basically, I am separating the array keys into a separate array and then using .sort() to sort the keys and then reassembling the original associative array elements according to the sorted keys array.

The sorting works ok except that when I run the test code below, the outputed sorted associative array has an extra element at the end of the array whose key is the name of the prototype function and the value for that element is the function code itself. Obviously I am misunderstanding something about associative arrays or how javascript prototypes work.

Multiple Variables Or Array Compared To Another Array?

Mar 8, 2010

how to accomplish this. In my website, I would like the user to input text into a single or multiple textbox(es) and then have the contents of the textbox(es) stored to either a variable or an array. Then I would like to have that variable/array compared to other arrays. Basically, the user is searching for items in a database. The user can search for as many or as little items as they want. Then the item(s) will be compared to multiple arrays to find out if what the user wants is in the database.

So for example, let's say the user is searching for recipes that have all or part of these ingredients: chicken, broccoli, lemon, honey. So, there would have been a total of 4 textboxes...one for each ingredient. These ingredients are stored to an array..lets call it ingredient(). In the database of recipes, each recipe has its own array which includes the ingredients needed to make the recipe, we'll call them tag1(), tag2(), and tag3(). Now, I want the array, ingredient(), to be compared to each of the "tag" arrays to see if any of the "tag" arrays include exactly match the ingredient() tag in part or in whole. Is this possible?
