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)?
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.
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?
How do I use array.push to add an object with a custom index in an array?I have this script but it doesnt work. Chrome's Javascript console is not outputting errors
var tempList = new Array();
$('#add').click(function(){
var split = $('#itemid').val().split('_');[code].....
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 ı sildiğim zaman, ne kaybederim?)
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.

I have seen this in help files and on a few other sites but I am not sure what the correct lingo is for this function but I am looking for a way to hide a layer of text below a heading and then make it appear when the heading is clicked but I need it to push down the text that is below it and not cover it up.

.push() to add clickedElementId as a value associated to a numeric key, but then the re-click is beyond my skills. How would you approach such a typical algo in javascript?
Im new to javascript. I want to add a similar function on my blog like on http://techcrunch.com/2011/08/04/gro...tartup-obtiva/ when you press on author. It is a drop down made with javascript. Anybody can help with a similar javascript as I was trying different implementations for the whole night with no luck.
Maybe, anybody know a similar javascript online which I could modify?
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.
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.
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?

View 1 Replies View RelatedI 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.

I'm getting this error when trying to simple traversing.

I read that it might have something to do with arrays?
This script is perfect to auto-scroll some text being sent in via php as a means of scrolling down to the bottom so users can read the incoming data. However, this one makes use of a button. how to make the script 'automatic' as text is being submitted to the div rather then by the push of a button?

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.

Does anyone know if a way to deliver web pages to an end-client using a push
method that can be controlled from your PC (by clicking on a page menu for
example - the pages can reside on a server). I have looked at CDF but I'm
not trying to create a webcast channel. I just want to deliver an html style
presentation with real time control from my end to a few users only at a
time. The type of system used by PowerPoint with the live broadcast feature
is what I am looking for but I want to have extra stuff on the pages than
just the slides and I also want to be able to move through the sequence
without relying on Powerpoint as my interface.
I'm looking for leads on a webpage component that would let me build a navigation bar type vertical menu where a mouseover event of a menu item would cause a submenu to appear below the item. The kicker is I'd like it to push the other menu items "down the page".
I've seen this on a number of sites, but I can't seem to figure out what it's called (at least, I haven't stumbled across the right words for google/deja searches yet).

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
What is the correct syntax for an nested array where each array element has 3 elements, a number and two text strings?
Code:
array = ['1, Old Man, Old Man','2 Black Sheep, Black Sheep',....]
should the text strings be in double quotes("")?
Code:
array = ['1, "Old Man", "Old Man"','2 "Black Sheep", "Black Sheep"',....]
