Nodes - Children[?] - With Html ?
Oct 1, 2010Having trouble with nodes: this time, childen[].
With this html:
HTML Code:
And multiple other divs with similar structure, id="2", "3" etc, I want to access the <p> tags to change style-- so that, for example, the last paragraph in all of the divs would change.
To access the last paragraph, I've tried:
Code:
--which generates an error message that the function itself is undefined.
There's till something I'm not understanding about using node-seekers with classes of tags. But if I can get it right, it saves giving each of the <p> tags a class, which would be easier, but code-heavy.

Aug 24, 2006Is it possible to remove a DOM node in Javascript without removing its children nodes. say I have

Can i remove ParentDiv but still keep Child1,Child2 on the DOM tree?
Why Are Anchor Nodes Pointing To Href And Text Nodes Pointing To [object?
Aug 6, 2010Consider following html code
<p id="oliver">
<a id="oliver1" href="/oliver1/">Oliver Twist 1</a>
<a id="oliver2" href="/oliver2/">Oliver Twist 2</a>
<a id="oliver3" href="/oliver3/">Oliver Twist 3</a>
<a id="oliver4" href="/oliver4/">Oliver Twist 4</a>
</p>
Applying JavaScript to above html as following:
[Code]...
Why are anchor nodes pointing to href and text nodes pointing to [object]? As anchor and text both are objects therefore all outputs from indices 0 to 7 should be [object].

Function To Add Text Nodes
Jul 24, 2005I have a bunch of numbers on my page, wrapped in a particular HTML element e.g.
<h2>5</h2>, <h2>1</h2>, <h2>3</h3>
I am looking for a javascript function that can add these numbers together. The tricky thing is that I do not know how many numbers there might be - anything from 0 to 7.
If necessary, I can give each of the <h2>'s a unique class eg. <h2 class="a">5</h2>, <h2 class="b">1</h2> etc.
Parsing Text With Markup Into Nodes
Jul 31, 2004I'm trying to figure out how I can take user input from a textarea and insert it into a table as HTML. An example:
<script type="text/javascript">
<!--
function echo_input() {
var input = document.getElementById("user_input").value;
var cell = document.getElementById("display_area");
cell.childNodes[0].nodeValue = input;
}
//-->
</script>
<form>
<textarea id="user_input" name="user_input" onkeyup="echo_input();"></textarea>
</form>
<table>
<tr>
<td id="display_area">test</td>
</tr>
</table>
The childNodes[0] that the script keeps editing is the text node that starts out as "test". The problem is that I want the text that I put in the table to be parsed if any markup is in it (so that a <br /> will become a break, and not literally printed out as "<br />"), something that the DOM automatically escapes. It seems a very cumbersome means of doing this is to write a javascript parser, which would go through the text and create different types of nodes as it stumbles upon markup.
Firefox Inserts Text Nodes In TR Elements?
Sep 23, 2005Why does Firefox insert #text nodes as children of TR elements?
As a work-around for older Safari versions not properly supporting a
table row's cells collection, I used the row's childNodes collection as
it was pretty much exactly the same thing. However, in Firefox 1.0.7
text nodes are inserted between the TDs. I'm certain that this didn't
use to happen with older versions.
The HTML specification states that the only element that can be the
child of a TR is a TD, so why does Firefox put text nodes in there?
If this how the DOM is supposed to be built, can someone give me a
reference to where it states that? Or should this be reported as a
Firefox bug?

Wrap Nodes Between Two Other Nodes In DIV Tags?
Apr 6, 2010What's the best way to wrap all the nodes between two nodes in DIV tags? Is it possible with the DOM? I have code similar to the following:
HTML Code:
<h3>First header</h3>
<p>First paragraph</p>
<p>Second paragraph</p>

How can I achieve this with the DOM, without resorting to doing something like a string replace?

do this, I'm using Microsoft Word VBA and using the following bit of

Extracting Parameters
Jun 2, 2007I found this little script for extracting parameters from a url but wondered
what the shortest and most efficient way to do it would be, like the
following or via regexp?
function getParameter(paramName) {
var currentUrl = window.location.search
var strBegin = currentUrl.indexOf(paramName) + (paramName.length+1)
var strEnd = currentUrl.indexOf("&",strBegin)
if (strEnd==-1)
strEnd = currentUrl.length
return currentUrl.substring(strBegin,strEnd)
}
Any shorter way?

Extracting Data From A XML Website?
Jan 18, 2011What will be the best way to extract dynamically changing information from a web page that holds XML?I have to extract some data from multiple web pages.These sites contain XML code that dynamically reloads (and changes) parts of the page.Since only small parts get a refresh (perhaps 200 bytes every 5 seconds) it wouldn't be efficient (and also might lead to negative reactions from the server) to reload the whole page (about 40k) every time.How could I best determine these updated contents and send them to the program that further processes them?I am familiar with several programming languages but unfortunately have very little knowledge of internet programming.

Sep 17, 2010I'm trying to get some average rgb values from an image in one canvas object and apply them via fillstyle to a rectangle in another canvas object.I have a dropdown that loads an image onChange()="ChangeBaseWood()" into a canvas object. The second canvas object is to be filled with an average color based on the content of the first canvas onClick="GetBaseColor()". For simplicity I've replaced the for loop with just the values of pixel 0,0. Where I think I am assigning the rgb values, the error console keeps reporting that var sample is undefined at the line "var redpart = sample[0].
function ChangeBaseWood(){
var dropdown = document.getElementById('woodvalue');
var woodcanvas = document.getElementById('basewood');[code]....
I've tried various things to assign the redpart,grnpart and blupart but I'm missing something basic.
Extracting Part Of A String?
May 20, 2011I have a bit of a problem and as my javascript is a rather poor I'm struggling to come up with a solution. Basically I need to split the variable "#country" into two parts and call the second half as the "this" value for '#int-dc'. Using '+' as the start point end ending at the end of the string.
For instance 'this' returns 12+44 I want to split it to "12" and "+44" the latter (+44) replacing 'this' in the code below.
$(function() {
$("#country").change(function() {
$("#int-dc").val
($(this).val());
});
});
Extracting Part Of A String From The Right?
Jun 15, 2011I need to extract a particular part of a string:
var str=(document.images('flag').src);
<img id="flag" src="../../../../img/ip/041-080/049p.png">
I only want the "041-080/049" part.
It needs to be read from the right, not the left because the preceding left part will vary in length.
Extracting XML Data Using GetElementsbyTagName?
Jun 9, 2009I'm trying to write code that will extract from an XML file and then display the results. Keep getting a syntax error.
HTML:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"
"http://www.w3.org/TR/html4/loose.dtd">
<html>[code]....
My intention was to access all of the tags (name, genre, and hitsong) in the XML file. Thought that var musicianInfo = xmlDoc.getElementsByTagName("*"); would do that. Then, loop through each tag and display the result.
Why isn't it working?

Extracting Item From An Array
Aug 17, 2011This randomising function is like a coin toss, it gives a numerical result and displays it:
function Ran() {
