JavaScript - Need Piece Of Code - Seems Simple Enough... Help!
Here's the basic concept, its somewhat of a counter, and I think javascripts the way to go...
Basically I'm looking to generate a running number... x + 11 = print the number The tricky part is, I need it to never stop, somewhat like a timer (example http://www.hashemian.com/tools/javascript-countdown.htm) but not a timer... Think the tally mark on McDonald's 99 billion served.. Any suggestions or ideas? Similar TutorialsHi, below is some code I've found at w3schools site. It demonstrates the use of "onkeypress" event by allowing only non-numerical input. It works great and is mostly clear to me, except for the part I marked in red. Could someone please explain this part to me step by step? It's probably a noobish question, but I thought you could only use "return" inside a function. Are "return true" and "return false" just optional parameters to the "onkeypress" event? If so, where else can they be used? Also what information exactly does the "(event)" being passed into the function "noNumbers()" carry? <html> <body> <script type="text/javascript"> function noNumbers(e) { var keynum; var keychar; var numcheck; if(window.event) // IE8 and earlier { keynum = e.keyCode; } else if(e.which) // IE9/Firefox/Chrome/Opera/Safari { keynum = e.which; } keychar = String.fromCharCode(keynum); numcheck = /\d/; return !numcheck.test(keychar); } </script> <form> Type some text (numbers not allowed): <input type="text" onkeypress= "return noNumbers(event)" /> </form> I need to understand this code but i am not able to fully understand it to use it for myself. Anybody can you help please function getScore(form) { var score = 0; var currElt; var currSelection; for (i=0; i<numQues; i++) { currElt = i*numChoi; for (j=0; j<numChoi; j++) { currSelection = form.elements[currElt + j]; if (currSelection.checked) { if (currSelection.value == answers[i]) { score++; break; } } } } score = Math.round(score/numQues*100); // math.round function will return the whole number to the nearest specified value for example 1.9 will show as 2 form.percentage.value = score + "%"; // The score will be displayed in percentage var correctAnswers = ""; for (i=1; i<=numQues; i++) { correctAnswers += i + ". " + answers[i-1] + "\r\n"; } form.solutions.value = correctAnswers; } Any short explanation will be a great help. I have a piece of code that pulls reviews and allows a business owner to drop the reviews on to their website. I need to limit the number of reviews and ideally I'd like to do that with just the snippet the biz owner drops into their site. Is this possible? Here's a sample of the code: <div id="repagent_reviews"></div><script type="text/javascript" src="http://awebsite.com/anotherwebsite/wp-admin/admin-ajax.php?action=repagent_reviews_js&id=1182"></script> thanks! confused I don't know anything about Javascript. My brother-in-law wanted me to update some pictures on his website. I found a piece of javascript code and am curious as to what it's function would be. Could someone please tell me what this piece of code is doing / what it's being used for. Thanks in advance. Here's the code: Code:

Here's the website that it's on: http://www.aircraftmodels.com/index.htm Hi, I have this code: Code: window.addEvent('domready',function(){
document.id('cool').addEvent('click',function() {
light = new LightFace.IFrame({ height:400, width:800, url: 'http://google.com', title: 'Google!' }).addButton('Close', function() { light.close(); },true).open();
});
});
It's a piece from something called the lightface iframe. What I want to do is to have this code on my javascript page, that's included on the main page where I want to call it. I call on it like this: Code: <a href="#" id="cool">Edit general info</a> However this only works if it's on the main page, not when I have it on my js page. So what I want to do is to turn it into a function, because that I know works. Could anyone help me with this? Thanks in advance for your time! Hi, can anyone help me with this?

Declare an 8 x 8 matrix and an array of length 22. 1.- Populate the matrix. 2.- Copy the elements of the first row of the matrix, the anti-diagonal, and the last row of the matrix into the array, to form a Z shape. 3.- Sort the array. 4.- Assuming that the data in the arrays are grades, compute the average of the grades stored in the even locations of the array. 5.- Copy the array back into the matrix.(back into the Z) 6.- Print out the matrix values.

Hi everyone, I've been coding Perl for quite some time, but I'm new to Javascript and can't quite figure this out. I want to call a Javascript function that is sent to the browser via a perl script. When I hard code the string "Fargo" into the code it works just fine, when I pass the word Fargo via a variable the script will not call the function what so ever. Is it possible to call a javascript function via a Perl script with Perl providing all the necessary data? Here is my code: #!/usr/local/bin/perl use CGI qw(:all); use CGI::Carp qw(fatalsToBrowser); use Cwd; print header; print "top<br><br>"; $data = "fargo"; print <<html; <html><head></head>my heading is here<br><body></body> <script type="text/javascript"> function testz(inbound) { document.write("im in ", inbound); } //the script will only work if I uncomment the line below and comment out two lines below //var data1="fargo"; var data1 = $data; testz(data1); </script> </html> html Thanks to everyone in advance for your help. can some please tell me what this line does... Code: <div onClick="getElementById('tInfo').onclick();">
