how to do you add elements to an array? am looking at section dealing
with arrays in JS Bible, can't find how you add to an array.. in the
last few years I've been doing much more Java than JS, am used to Java,
where you can't add elements to an array, but use a Vector instead.. and
it's very easy to add to it (use add() method..) how to you add
elements to an array in JavaScript..
I looked up array obj, don't see method to add to array.
Since the Array.splice() method isnt supported by IE5 here's a script with an add function and a remove function.
function remove(nr) {
var nb = parseInt(nr)
for(x=nb;x<myArray.length-1;x++) {
myArray[x] = myArray[x+1]
}
myArray.length += -1
}
function add(nr,value) {
for(x=myArray.length;x>nr;x--) {
myArray[x] = myArray[x-1]
}
myArray[nr] = value
}
You can test it out by including the following html, and an array in the script (here named 'myArray').
<body>
<form>
Nr to add/remove<input type="text" name="nr" /><br />
Value to insert <input type="text" name="val" />
<input type="button" value="remove" onclick="remove(this.form.nr.value)" />
<input type="button" value="add" onclick="add(this.form.nr.value,this.form.val.value)" />
<input type="button" value="View Array" onclick="aA()" />
</form>
</body>
</html>
And this small function
function aA() {
for(x=0;x<myArray.length;x++)
alert(myArray[x])
}
I'm trying to solve a problem with JS textbox array without success.
I have two buttons in my page: PLUS and MINUS; at every click on PLUS a new
textbox named 'dear' is generated. So, if one clicks, say, 3 times the
output is something like:
dear[0]
dear[1]
dear[2]
The length property is accessible; alert(dear.length) gives Ɖ', correctly.
The prolbem is that is not possible to delete a textbox, clicking on MINUS
button. The thing I'd really need to do is to delete from the array (and in
consequence from video) the last textbox created, when one clicks on MINUS
button.
Pop() and Splice() methods do not work, unfortunely...
This is the exact code of my page:
<a href="#plus" onclick="john.innerHTML+='<li><input id=dear type=text
size=50>'">
[PLUS]
</a>
<br>
<a href="#minus" onclick="alert(dear.length);dear.pop()">
[MINUS]
</a>
<ul>
<div id=john>
</div>
</ul>
Years ago I created HTML that employs checkboxes and textboxes. I am now writing JS with the intention of adding flexibility and limiting redundancy. I am not sure I truly understand how to correctly interact the two though. For example, one of my scripts have arrays that contain the names of the checkboxes and textboxes, with a 'for' loop to document.write() them to references within the HTML code.This does not seem to be working for me though. Here is what I have thus far (in short):
<script language="javascript">
var teamNames = new Array(3);
teamNames[0]="South Africa";
teamNames[1]="Mexico";
teamNames[2]="Uruguay";
[Code]...
I've left out a lot of the code (to include the teamAbbr array, but you get the points. I've tried moving the JS within the HTML body and playing with the reference syntax, but nothing so far.
I having been trying to make the data from generated (using div tags) pairs of textboxes into two separate arrays, a[] and b[]. I thought that if I label each text box pair a[i] and b[i] that would be enough to include the respective element in each array but that hasn't seemed to work. In fact. the only way I managed to retrieve the values from the text boxes was using "getElementById" and resorted to a for loop in order to make the arrays but that method appears to be able to get elements from only one pair of text boxes. Code:

Code:

should the text strings be in double quotes("")?

This one is throwing me off! Either I am making a stupid mistake or I'm doing it totally wrong I have an array, and I am trying to select unique values from it and assign it to another array. Here is the code:
Code:
var flag;
for (i=0;i<=pdfs.length-1;i++)
{
flag = 1;
for (j=0;j<=pdfs2.length-1;j++)
[Code]...
The problem is that the if (pdfs2[j] == pdfs[i]) statement ends up never being true. There are URL's to pdf files in the array. On the other side, if there is a much easier way to select unique values from an array, please feel free to point it out.
I'd like to reorganize the third, fourth, fifth and sixth, as well as any
elements thereafter in an array in random order:
var a = new Array('first','second','third','fourth','fifth','s ixth','etc')
In other words, the first, second and third element should remain in
position 0, 1 and 2, while the fourth, fifth and sixth, etc. should appear
in random order.
I have probably a really easy question but i just cant figure it out.I want to add a <div> element every time it goes through a loop a .each in this case.I had it working in prototype before:

I have a javascript method that adds a good portion of HTML to the DOM after an AJAX request completes. It's an image uploader... so once an image uploades, I add it to the list of images along with a save and delete button. Normally when a user clicks save or delete (they are specified as classes with images called save and delete), a javascript method is called.
Problem is, when I add another image to the list along with its save and delete images, they aren't going to respond to the clicks. I know this is because I already did the
$('.save').click(function (element) {
saveImage(element);
}
script in the document ready. Is there a way to get the new DOM stuff I just added to also apply to that?
Im sure this is possible, does anyone have any code/pointers?

View 1 Replies View RelatedI'm trying to make a form that will generate some code for game based on what they fill out. The code will be a modification menu of sorts. They will be able to name the menus and submenus and add or remove them if they want.

I'm baiscally trying to get some twitter feeds and the rotate them. I can get it and everything like that but for some reason the jQuery doesn't pick up the divs that I appended to the container because when I alert the div.length like this: alert(divs.length); The result is always zero. The code works fine if I can populate that value but if I don't have it in the code before hand it doesn't work. However if I add a div to the container like this:

I am after adding a mouseover (and mouseout) to a div tag, however this mouseover and mouseout will require an element id passing to it to work. Currently the tag is
<DIV class="mc-c" onMouseOver='document.getElementById("ID1").className="mc-h-on"' onMouseOut='document.getElementById("ID1").className="mc-h-off"'><DIV id="ID1"></DIV></DIV>
but the tag will soon become
<DIV class="mc-c"><DIV id="ID1"></DIV></DIV>[/
The ID1 is generated when rendering the HTML and there may be multiple of these tags (each with a different ID#).I would like to add the same functionality as the first bit of code to the second, does anyknow know of this. I have been able to add mouse overs to DIV's already, however passing a variable to it I am struggling with
I am using infinite scroll plugin. I am adding new elements to the page. I would also like to add a div using after().However because these elements are being added after the DOM has loaded, it is not being picked up.Here is the code I tried.
$('ul li:nth-child(4n)').live('after', function(){
return '<div class="clr"></div>';
});
After reading the documentation I realized that after() cannot be used with live(). So, how could I achieve this then?
i'm trying to add a row to a table with form elements in the table. It almost works but instead of seeing my text field, i see the code of my text field. Here's my code :

var tbody = document.getElementById(tableName).getElementsByTagName("TBODY")[0];
var row = document.createElement("TR");
var td1 = document.createElement("TD");
td1.appendChild(document.createTextNode("<input type='text' name='myInputs[]'>"));

I'm justing wondering about the behavior of JS in regards to adding elements, suppose I have something like this:
I'm just wondering at the point I hit that "// DO SOMETHING WITH ONE OF THESE DIVS", are all the divs I have added in the DOM available to access?
I ask because I have some code at work in which a tester is reporting an error that happens which I can't reproduce, and they and others have had it a few times.
The only way I can explain it in my mind is if the div is not available to me at the time of execution. So I'm just looking to rule it out or confirm my hunch.
Is document.getElementById("myDiv").appendChild(obj); synchronous and the next line of code wont execute until the DOM is ready or is it in fact a asynchronous call and therefore adding alot of elements to the DOM could result in a lag so some divs or not available straight away.
I'm using the following function to access elements with specific attribute values in an XML file. These elements then also have child elements, which contain the required data to be rendered as HTML. Code:

The problem is aside from my intro page, most of my other pages use a header and footer on the server side. The body tag is inside the header so I don't have access to it on the other pages. I tried adding a simple function at the bottom of the page, but it does not work.
