JavaScript - Help With Time Code
Hello,
I am currently working on a site where I need to display the date. The portion I'm working on looks something like this: Yesterday Entries for Today's Date Tomorrow If the user clicks the yesterday link, then that date needs to show. The same goes for the tomorrow link. Otherwise, the current date will show. I have most of the function setup. The problem is I don't know how to check whether or not a link has been clicked. I also need to know how to setup the function within the link. Here's what I have: <a href="#" onclick="javascript: previous(yd);return false">Yesterday</a> The onclick event is supposed to refer back to the function I created to determine what date to display based on which link the user clicks. So my questions a 1) Is my link setup properly to allow the function to run? 2) How can I check to see whether or not a link has been clicked in my function? Any help/suggestions are greatly appreciated!! Thanks in Advance Similar TutorialsHello. I just want to check whether it is possible (and if so whether there is one available) to have a script that displays MY current time and date to visitors to my website. My time is Western European Time or Greenwich Mean Time. I would like visitors from eg Japan to see my local time and not their own. I think some date scripts I have seen use the user's local PC clock, but I am not sure? Thanks for any feedback and help! Hello, I want to run video at our website at a specified time only,like i might want my video to be played at 9.00a.m exactly . how can i do it using javascript. Plz do revert back ASAP. Thanks, Revathi srikrishna I have a javascript controlling the display of a DIV that I did a while back that needs a bit more tweaking to add function to hide the DIV on specific holidays. As it is now, by default, the DIV is being hidden unless it is M-F between 8:00AM-6:00PM: Code: <script type="text/javascript"> onload=function(){ var rightNow = new Date(); var day = rightNow.getDay(); var hour = rightNow.getHours(); var minute = rightNow.getMinutes(); var formDisplay = 'none'; // unless we see otherwise var forwardDisplay = 'block'; // unless we see otherwise if(day==1 || day==2 || day==3 || day==4 || day==5) { // if chat is avalable on these days if((hour>=8) && (hour<=17)) // if chat is avalable between these times formDisplay = 'block', forwardDisplay = 'none'; } document.getElementById('ChatForm').style.display = formDisplay; document.getElementById('ChatForward').style.display = forwardDisplay; } </script> Im assuming that I would just add more else if statements, but not really sure the cleanest way to assign specific dates using this format.

However, I want to achieve to display the time difference between a given start and end time. Right now, it calculates from the current server time to the end time. I want to be able to set up my own start time and end time. Here is what I have: http://jsfiddle.net/BgEtE/ thank you for help I'm not really a Java writer, so I don't know how to do this myself, though I imagine it would be pretty simple. I am looking to add a script to a webpage that allows users to input a time manually, and have it converted to GMT/Zulu time and display the converted time. I have seen a lot of time zone conversion scripts online, but they all just convert whatever the current system time is to another time zone. I am looking for a script that allows users to convert a time and show the zulu time, for times other than the current time. The time zone the inputed local time would be in is +4:30 (Kabul). I don't really care about style or aestehtics, just a simple script I can insert into a web page to have a time input field. The converted output time can appear in another field, a popup bubble, etc, again style isn't really an issue. It's really just to help people in my job who need to know what the GMT/Zulu time was for certain local times after the fact. One would think it shouldn't be that hard to just subtract 4:30 in your head, but apparently it is. Sorry if just asking for code outright like this is frowned upon. hi, can some one help me how to get the time and date difference? given two time and date with the following format like in textbox A: 2011-05-03 17:35:47.0 and textbox B: 2011-05-03 16:35:47.0 then the output would be: 0 days, 1 hour, 0 minutes, 0 seconds regards, verve This is my first time doing JavaScript I don't what I did wrong here, but the problem its not showing up the current date and time. Code: <script language = "JavaScript" type="text/javascript"> now = new Date(); localtime = now.toString(); utctime = now.GMTString(); document.wite("<b>localtime</b>" + localtime + "</br>"); document.write("<b>utctime</b>" + utctime); </script> This is what supposed to look like I have tried using different browser chrome,IE9,Maxtor, and Opera my OS is Win7 Hi there!

Hi - I have a date in my javascript like this: Mon Dec 12 00:00:00 UTC+0430 2011 I need to convert it to a date without the offset (the +0430). I actually changed my computer's timezone to generate this offset - we have uses placing orders on our site who don't use UTC and it's throwing our orders out as they need to select a delivery date but it's passing the date with the offset. How do I convert a date to UTC time? Thanks This post will contain a few guidelines for what you can do to get better help from us. Let's start with the obvious ones: - Use regular language. A spelling mistake or two isn't anything I'd complain about, but 1337-speak, all-lower-case-with-no-punctuation or huge amounts of run-in text in a single paragraph doesn't make it easier for us to help you. - Be verbose. We can't look in our crystal bowl and see the problem you have, so describe it in as much detail as possible. - Cut-and-paste the problem code. Don't retype it into the post, do a cut-and-paste of the actual production code. It's hard to debug code if we can't see it, and this way you make sure any spelling errors or such are caught and no new ones are introduced. - Post code within code tags, like this [code]your code here[/code]. This will display like so: Code: alert("This is some JavaScript code!") - Please, post the relevant code. If the code is large and complex, give us a link so we can see it in action, and just post snippets of it on the boards. - If the code is on an intranet or otherwise is not openly accessible, put it somewhere where we can access it. - Tell us any error messages from the JavaScript console in Firefox or Opera. (If you haven't tested it in those browsers, please do!) - If the code has both HTML/XML and JavaScript components, please show us both and not just part of it. - If the code has frames, iframes, objects, embeds, popups, XMLHttpRequest or similar components, tell us if you are trying it locally or from a server, and if the code is on the same or different servers. - We don't want to see the server side code in the form of PHP, PERL, ASP, JSP, ColdFusion or any other server side format. Show us the same code you send the browser. That is, show us the generated code, after the server has done it's thing. Generally, this is the code you see on a view-source in the browser, and specifically NOT the .php or .asp (or whatever) source code. I'm trying to get my Client Side Firefox DHTML app to display a list of eBooks. For this, i have the following files F:\Textbooks.html F:\eBooks.txt F:\FirstBook.txt F:\SecondBook.txt F:\ThirdBook.txt textbooks.html is my DHTML app eBooks.txt is the Library file with a listing of all of my eBooks. Inside of eBooks.txt is the following data: ----------------- FirstBook.txt, SecondBook.txt, ThirdBook.txt, ----------------- FirstBook.txt to ThirdBook.txt are my actual ebooks. The problem that i'm having is that When i try to click on any buttons other than the FirstBook button, i get the following error: ---------------------------------- Error: unterminated string literal Source File: file:///F:/Textbooks.html Line: 1, Column: 10 Source Code: LoadEbook(' ---------------------------------- So, unlike clicking on the FirstBook button, these other buttons do not load the eBook data into the DIV for displaying the eBook data. I use the DOM insepector to checkout the DOM of the button code, and it seems like whitespace maybe is the problem. However, i have removed whitespace from the HTMLdata string, and that's not fixing the problem. did i forget something silly? LOL i'm using FireFox 3.5 to develop this App. So obviously this will not work with anything other than Gecko Based browsers. here is my HTML code: <html> <head> <script language="JavaScript"> var eBookLibrary = "eBooks.txt"; var SystemPath = "f:" + String.fromCharCode(92) function Init() { // Initialize the eBook reader document.getElementById("EbookCanvas").style.visibility = "hidden"; document.getElementById("EbookToolbar").style.visibility = "visible"; document.getElementById("FileManager").style.visibility = "visible"; // Load the List of eBooks in the Library LoadBookList(); } function UpdateEbookList() { // Update the Library of Ebooks alert("Updating eBook Library"); // Go back to the File Manager, and Reload the List of Ebooks LoadBookList(); } function LoadBookList() { // This will load the list of books that are available var EbookList = LoadFromDisk(SystemPath + eBookLibrary); var EbookListArray = EbookList.split(","); for(var x = 0; x < EbookListArray.length -1; x++) { // Strip the Filename Extension off of the eBook File Name // The Name of the Book is always the first Index in the Array var BookName = EbookListArray[x].split("."); // Remove the weird whitespace - it screws things up...i think... BookName[0] = BookName[0].replace(/(^\s*|\s*$)/g, ""); var HTMLdata = HTMLdata + "<input type='button' value='" + "FirstBook" + "'" + " onClick=LoadEbook('" + EbookListArray[x] + "');><br>"; } // For some ****ed up reason the first string always generates an 'undefined' even though it's nonsense // So just delete that from the HTMLdata string, because it's just ugly - LOL HTMLdata = HTMLdata.replace("undefined", ""); HTMLdata = HTMLdata.replace("", " "); // Write the HTML data to the DIV document.getElementById("FileManager").innerHTML = HTMLdata; } function LoadEbook(EbookName) { // Hide the File Manager and Show the Ebook Canvas document.getElementById("FileManager").style.visibility = "hidden"; document.getElementById("EbookCanvas").style.visibility = "visible"; document.getElementById("EbookToolbar").style.visibility = "visible"; // Load the Ebook content into the Ebook Reader Pannel var EbookContent = LoadFromDisk(SystemPath + EbookName); document.getElementById("EbookCanvas").innerHTML = EbookContent; } function LoadFromDisk(filePath) { if(window.Components) try { netscape.security.PrivilegeManager.enablePrivilege("UniversalXPConnect"); var file = Components.classes["@mozilla.org/file/local;1"].createInstance(Components.interfaces.nsILocalFile); file.initWithPath(filePath); if (!file.exists()) return(null); var inputStream = Components.classes["@mozilla.org/network/file-input-stream;1"].createInstance(Components.interfaces.nsIFileInputStream); inputStream.init(file, 0x01, 00004, null); var sInputStream = Components.classes["@mozilla.org/scriptableinputstream;1"].createInstance(Components.interfaces.nsIScriptableInputStream); sInputStream.init(inputStream); return(sInputStream.read(sInputStream.available())); } catch(e) { //alert("Exception while attempting to load\n\n" + e); return(false); } return(null); } </script> </head> <body onLoad="Init();"> <div id="FileManager" style="position: absolute; top: 0px; left: 0px; visibility: visible;"> The eBook Library's List of Books will be listed here.

From time to time, I need to send password information or login details and password information to some users. At the moment, am doing it via email with a subject named FYI and the body of the email basically just contain the login and the password or in some case, just the password. What am wanting to know is whether I can put these information into a HTML file which contains an obfuscated Javascript with a button that a user will click that will prompt for his login information and then will display the password. In its simplest form, I guess I am looking for a Javascript that will obfuscate a HTML file that contains the password. Anyway, hopefully someone understand what am looking for. I found some website that offers such service as obfuscating a HTML file but am hoping it can be done via a Javascript so it is at least "portable" and I do not have to be online. Any advice will be much appreciated. Thanks in advance. Hey everyone here is my code for looking up a city, and state by zip code.

Im not good with JS at all I am trying to set up a looping structure that tests to see if the user enters a value.

AIM: I have a form that takes in times a person was doing an activity, and you can enter multiple times & activities in one go. e.g. Person A | Lunch | 12:00 - 13:00 | Meeting | 13:30 - 14:00 I need the JS to validate that Activity B (Meeting in the above example) does not overlap with Activity A (Lunch in the above example). It also needs to check this for all activity's so that none overlap with each other else output error. I have managed to do this server side in PHP and will include the code as it may help show what I am trying to do better than Im explaining. PHP Code Code: $Code = $_POST['code']; $NumberofCodes = count($Code); $Start = array(); $_POST['starthr'] = array_values($_POST['starthr']); $_POST['startmin'] = array_values($_POST['startmin']); $i = 0; foreach($_POST['starthr'] as $key1 => $value1) { $Start[(int)$i] = $_POST['starthr'][$key1] .":". $_POST['startmin'][$key1]; $i++; } $Stop = array(); $_POST['stophr'] = array_values($_POST['stophr']); $_POST['stopmin'] = array_values($_POST['stopmin']); $i = 0; foreach($_POST['stophr'] as $key1 => $value1) { $Stop[(int)$i] = $_POST['stophr'][$key1] .":". $_POST['stopmin'][$key1]; $i++; } $i = 0; $j = 1; while ($i < $NumberofCodes){ while(($j-1) < $NumberofCodes){ if (($Start[$j] > $Start[$i] && $Start[$j] < $Stop[$i]) || ($Stop[$j] > $Start[$i] && $Stop[$j] <= $Stop[$i])) { //Stop form executing and provide error information. } $j++; } $i++; } JS Code (What I could manage) Code: var i = 0; var j = 1; var Start = new Array(); var Stop = new Array(); var aa = new Array(); var bb = new Array(); while (i < counter){ while((j-1) < counter){ Start[i] = document.myform.elements('starthr['+i+']').value + ":" + document.myform.elements('startmin['+i+']').value; Stop[i] = document.myform.elements('stophr['+i+']').value + ":" + document.myform.elements('stopmin['+i+']').value; var a = toDate(Start[i],"h:m") var b = toDate(Stop[i],"h:m") aa[i] = a; bb[i] = b; function toDate(dStr,format) { var now = new Date(); now.setHours(dStr.substr(0,dStr.indexOf(":"))); now.setMinutes(dStr.substr(dStr.indexOf(":")+1)); now.setSeconds(0); return now; } if ((aa[j] > aa[i] && aa[j] < bb[i]) || (bb[j] > aa[i] && bb[j] <= bb[i])) { //Fail validation } else { //Pass Validation } j++; } i++; } Any help on this would great. Thanks Barry Hi brothers and sisters, My first post here. I am trying to do a self-test system for my small company, everything is going smoothly so far however, I am facing some problem with setting a cut off time for doing the test. For example, my staff could not go in to the system after 8pm. Anyone had any idea on how to do it?? I have only some basic knowledge of php which I learn in school thus setting time limit might be too advance for me thus need you guys help. Thank alot |
