I am developing an application which allows a web site visitor to email a page to a friend using the PHP mail() function.
What I would like to do is dynmaically extract the H1 from each page using JS and store this as a PHP session named title. Can I get this info using JS?
I'm slowly discovering the world of JavaScript, so I'm not sure I'm
attacking this problem in the right manner, thus if I'm in the wrong
newsgroup, my apologies.
What I'm trying to do is extract some news items from a web site. To
do this, I'm using Microsoft Word VBA and using the following bit of
script:
I 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?
Is there any method to extract both the images (with and without
mouse-over) from a web site.
What 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.

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.
I 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());
});
});
I 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.
I'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?
I have a records that come from a database.
My string, wich is "{module_webapps,5007,l,1}" returns the following:

All I need is the actual img src url, like:

Is there a way to pull the image url from the string with Javascript?

This randomising function is like a coin toss, it gives a numerical result and displays it:
function Ran() {
var c = Math.random();
return (c < 0.5) ? [0, show0()] : 1, show1()];
}
I want to extract the numerical outcome, 0 or 1, from this and from two other similar functions, sum them, and then run more functions based on the possible sums.
What is the syntax for getting to the numbers? something like
var n = Ran().[0] ?
I have a simple form that puts the info into cookies. I then need to check the entered name against the cookies, to see if they are the same. Currently there does not seem to be any cookies to check against, becuase my window.alert comes up blank. Please look over my code and see if you can spot the issue:
Code:
function getCookieData(labelName)
{
var labelLen = labelName.length;
var cookieData = document.cookie;
var cLen = cookieData.length;

Pseudo-code (which of course doesn't work), so you get the idea:

I want to store four cookies -- the name, the date the cookie was set, and the user's preferences for background color and foreground color. The name is set to John, the date set to 03-28-2005, the background color is set to red, and the foreground color is set to green.
Question 1: What is the entire cookie string (or name-value pair) returned when John visits the webpage?
Question 2: What code to use to extract the four values from the cookie string? The code should be written in a way that these values can be extracted wathever the order they appear in the cookie string.
Question 3: Why is it a good idea to store the date that the cookie is set? How is this information be useful?
Trying to figure out how to use javascript to extract all links on a page that have a certain class:
e.g. - extract only links with a class of 'tools', ignore all other links:
<a href="http://www.google.com" class="tools">Search</a>
<a href="http://www.tripod.com" class="grapes">Searched</a>
<a href="http://www.dogpile.com">Searches</a>
I'm guessing I probably have to use something like getelementbyclass("tools")?
I am trying to extract the value from a selected item in a Select/Option, parse it server side using asp and then populate a text box on the same page with the value that was parsed. simple example below:
Two problems I have here:
1. The code: this.frmEditUser.Submit; does not appear to submit the form.
2. If I submit the form using the Submit button, it works except I get:
I'm an ASP developer by trade, but I've had to create client side

Now I've been assigned the task of extracting content from a given HTML
page. If anyone's familiar with the Yahoo! Store order confirmation
screen, I need to be able to grab the total amount from the table to
the right-hand side. (Sample File:
http://www.2beyourself.com/t/sample.html)
If you view the source, this is in a table and enclosed with ugly html.
the value I want to retrieve is wrapped with b tags. Originally I was
thinking of using innerHTML or innerText for extracting the value. But
I find that we cannot gain control of this piece of the Yahoo! Store to
make it work!
So after talking with peers, we thought of reading in the entire HTML
page and using regular expressions to try and extract the value.
Something along the lines of: '<b>[0-9]+.[0-9]{2}</b/>'
I'm not sure how to accomplish this. Could someone please point me in
the right direction? If this solution is even a good one. If you have
something better, I'm all ears! (eyes) If using the regular expression
would be a good solution, I need to find out how to read in the entire
HTML doc, and then parse out that piece.
I'm attempting to write a quick piece of Javascript code that will
validate if the end user of the javascript has the necessary VML
attributes set in their HTML. The problem in IE is that "xmlns:v"
does not appear in their attributes property or the
getAttribute('xmlns:v') calls. The real kicker is that the 'xmlns'
attribute does return something.
The HTML Snippet would look like this:
