Extracting Part Of A String From The Right?

Jun 15, 2011

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.

Extracting Part Of A String?

May 20, 2011

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());
});
});

Extracting Parameters

Jun 2, 2007

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?

Extracting Data From A XML Website?

Jan 18, 2011

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.

Extracting Data From .getContext(ƈd')?

Sep 17, 2010

I'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 XML Data Using GetElementsbyTagName?

Jun 9, 2009

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?

Extracting Item From An Array

Aug 17, 2011

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
