Programming :: Executive JavaScript Function Along With URL
Jun 15, 2011
There is this sample web page: [URL] and it has a clickable link / button that executes a JavaScript function: (Right-Click and Copy Shortcut would give this piece of code)
Code:
javascript:__doPostBack('lbtnUpdateStatus','')
whereas the source code for the link / button is as follows:
Code:
<a id="lbtnUpdateStatus" href="javascript:__doPostBack('lbtnUpdateStatus','')">
I want to automate the above function / link along with the said URL so that I won't have to open the webpage and click the button / link. I want a single URL hitting which we won't need to do the extra effort of "clicking the link / button" that executes the JavaScript function given above. I can't automate this task in the source webpage itself because that has to be there as it is for the users who access the webpage. How to achieve it?
I got some useful information here: [URL] but I want to call a javascript function along with a URL such as this:
Code:
[URL] javascript:alert("OKAY")
but the above line of code won't work.

In my book, this is an example of a recursive algorithm:
var reverseArray = function(x,indx,str) {
return indx == 0 ? str : reverseArray(x,--indx,(str+= " " + x[indx])) ;; }
var arr = new Array('apple','orange','peach','lime');
var str = reverseArray(arr,arr.length,"");
alert(str) ;
I'm trying to understand it, I'm stuck at the (str+= " " + x[indx])) part - that part of the function definition expects an ARGUMENT, am I right? What's being passed to it is a bit of PROGRAM, the str+= stuff. So - how is it working?

I am doing some Linux kernel programming for my research project. I need to record the timestamp (by using cpuid and rdtsc) when an interrupt handler (top half) is first invoked. Due to the time critical nature of the problem itself, I have to do the timestamping inside the interrupt handler itself (the first operation when the handler is called). However, I understand that tasks that are not so time critical should be deferred to a tasklet function (bottom half) for processing because other interrupts are disabled in a (top-half) interrupt handler. I am currently out of idea on how I can pass the timestamp information that I have obtained in the interrupt handler to the corresponding tasklet function.

I went to [URL] the other day, and I'm really impressed with the way, when you click on domain, it adds it to the cart WITHOUT A REFRESH. But what I really want to know is - how does it do the slick little effect when you click "Add to basket", when it "appears" on the right hand side?

I have some variables that are loaded from mysql - in mysql, the line breaks are not indicated by ' or '<br>' or anything -they are just line breaks. the variable is loaded into javascript and then inserted into a <pre> element. the line breaks are not showing up.
pre1 = pre1.replace(/>/g,">"); - this works well, naturally. but how do i get those line breaks to show up as line breaks in a browser?
I've tried many variations of something like:

Lets say I have a site "Website1.com"
On that site I want to run a little javascript that verifies that the site was accessed as "Website1.com" and not "dev-Website1.com"
If it was accessed correctly, nothing happens. If it was accessed incorrectly, it displays an error saying "You are trying to access this site incorrectly."
What is the simplest way to accomplish this?

I am using window.onbeforeunload to keep people from accidentally leaving. I was hoping to intercept this event, run my own dialog box and load another page that closes the window, or of course, cancel.
I'm needing this because my site is a single page and I can't figure out how long people are visiting for, if I could load an exit page, then I can figure this out.

When someone is speaking into the mic, I'd like a "level meter" such as the one that comes with gnome sound recorder, that flashes up and down when a sound is made or somebody talks.This will be done in Javascript, using the brand new "Rainbow API", i.e. inside the browser.I know nothing about audio programming, so - where would I get *started* with something like this? Could anyone tell me at least WHAT to Google?

I'm loading an XML file stored in a tiny web server (based on lwip). This web server is not very cooperative and is not marking the http content-type as "text/xml". As result, Firefox is not recognizing the file as xml (IE does) so I can't use DOM methods for parsing the xml file. overrideMimeType("text/xml") should help me avoid this problem but, even having overrided the mymetype, the content-type received is still "text/plain". This is a portion of my JavaScript code:
Code:
var xmlObj;
// loadXMLdata is called from the html file
function loadXMLdata() {
var dataFile = window.location.href.substring(0, window.location.href.lastIndexOf("/") + 1) + "config/myfile.xml";
if (window.XMLHttpRequest) {
xmlObj = new XMLHttpRequest();
// This should override the mimetype...
if (xmlObj.overrideMimeType)
xmlObj.overrideMimeType("text/xml");
xmlObj.onreadystatechange = fillXMLdata;
xmlObj.open("GET", dataFile, true);
xmlObj.send("");
} else {
alert("Your browser can not handle this script");
return; } }
// fillXMLdata is called from loadXMLdata once the xml object is ready
function fillXMLdata() {
if (xmlObj.readyState == 4) {
// Here Content-Type shows again "text/plain"
alert(xmlObj.getAllResponseHeaders());
var xmlDoc = xmlObj.responseXML.documentElement;
// And here section is null
var section = xmlDoc.getElementsByTagName("section")[0]; } }
The xml is quite simple:
Code:
<?xml version="1.0" encoding="iso-8859-1"?>
<section>
<item>1</item>
<item>2</item>
</section>

I'm working with javascript and trying to replace all instances of a Roman character in a string with nothing. How do I assign var reg to all Roman characters? In UTF8, capital letter A is U0041 and at the other end, small z is UFF5A.
So, I'd like to do something like:
var reg = u0041 - UFF5A;
str1 = str.replace(reg, '');
I think you get the idea. I have no idea if that can be done. The idea is to take this string (for example): str = make a door-to-door[house-to-house] visit / ring every doorbell." And take out all the Roman characters and define it as str1. And then take out all the Korean characters (u1100-uFFDC) and define it as str2. In fact, a WAY more useful thing to do would be to replace the instance of this: [u1100-uFFDC]+" "+[u0041-UFF5A] with [u1100-uFFDC]+","+[u0041-UFF5A] so that the output would be a .csv file.

I'm looking for javascript tutorials or books that meets the following criteria:
1. Very thorough: Starts with the most fundamental concepts and progresses logically from basic to advanced concepts, without skipping over important ideas for the sake of expediency.
2. Lots of small practice exercises that parallel the concepts and syntax being learned.
I've looked at a lot of tutorials, but they all tend to be lacking in one of these areas or the other.

I am trying to set up a webpager that contains a background of the skylouds uperimposedin the center will be an image of an airplane with a transparent background.I want the sky to scroll continuously to the left behind the airplane. I am having problems with the background not being visible, not moving as expected, the airplane not being visible, and just disappointment in general.I think the background of a div will not be visible if there are no internal contents because it will be sized to zero. So I introduced another transparent image to force the size of the main div. Still no joy.Here is my code. Note that I don't have my timers set up yet, just a button to test background movement.

<!DOCTYPE html>

All I want to do is fade some text in and out via the opacity attribute, and change the text when it hits zero. My script changes the text on time, but ignores the formatting effects. I'm not worried at this stage about the else statement in the startFadeEffect() function. I just want the fade effect to work here the way it should.

fit a surface i.e. W(x,y) using svdfit() provided by "Numerical Recipes in C". svdfit() is written for curve fitting and not for surface fitting.But one can use svdfit(), as claimed by authors of NR book, to do surface fitting. On page 680 of NR book, authors have given a hint on how to use svdfit() for fitting a surface. But I have not understood it.This link may be helpful (Chapter 15 th is relevant here.):[URL]This is my problem:
