JavaScript - Storing Date In Localstorage
I'm trying my hand at localstorage (which is HTML5), but I'm combining it with javascript (which is... erm, well, javascript ) so I decided to put this in the javascript forum. If I'm wrong, I apologize. Anyway, though I'm not a complete newbie when it comes to coding, this is new for me and frankly, I'm stuck.
What I'm trying to do (nothing special, just messing around a bit) is show the current time and the time the visitor last visited. I made this: Code: var tijd = new Date();
var oudetijd = tijd.getTime();
localStorage.setItem('laatste bezoek', oudetijd);
var laatstebezoek = localStorage.getItem('laatste bezoek');
document.write(laatstebezoek + "<br>");
document.write(oudetijd);
Should work, right? Well, it does... partly. It shows the current time (woohoo!!! ) but the "old time" (oudetijd) is exactely the same! Now, I know I'm doing something wrong here, most likely something stupid like a missing comma, but whatever it is, I don't see it. Can someone shed some light on this? P.S. As you can probably see from the code, I'm Dutch. I dont know if it helps or not, but here's a translation: tijd= time oude tijd = old time laatste bezoek = last visit Thanks in advance! Similar TutorialsHello, I really need your help with one. How can I use the following code below to save the date from my popup window datepicker back into a var and relay it back onto its parent page? I can't seem to figure this out: Code: <html>
<head>
<script>
function open_cal() {
var str_html = ""
+ "<!DOCTYPE html>\n"
+ "<html lang=\"en\">\n"
+ "<head>\n"
+ "<meta charset=\"utf-8\">\n"
+ "<title>CALENDAR</title>\n"
+ "<link href=\"jq/jquery-ui.css\" rel=\"stylesheet\" type=\"text/css\">\n"
+ "<script src=\"jq/jquery.min.js\" type=\"text/javascript\"></" + "script>\n"
+ "<script src=\"jq/jquery-ui.min.js\" type=\"text/javascript\"></" + "script>\n"
+ "<script src=\"jq/datepicker.js\" type=\"text/javascript\"></" + "script>\n"
+ "</head>\n"
+ "<body>\n"
+ "<div id=\"text\" style=\"font: bold 10pt Tahoma\">Enter Approval Date:</div>\n"
+ "<div id=\"datepicker\"></div>\n"
+ "</body>\n"
+ "</html>"
var j = window.open("","CALENDAR","width=200,height=250,status=no,resizable=yes,top=200,left=200")
j.opener = self;
j.document.write(str_html);
}
</script>
</head>
<body>
<input onclick="open_cal()" type="button" value="Open" name="B1">
</body>
</html>
Datepicker.js: Code: $(function() {
$( "#datepicker" ).datepicker({
dateFormat: 'dd/mm/yy',
onSelect: function(dateText, inst) {
alert(dateText)
window.close()
}
})
});
Any help with this is greatly and mostly appreciated. Thanks in advance, Cheers, J Hello, I hope someone can help. I know on the front end using js you can get the date and time on client machine and store in a hidden field so it can be grabbed to use on the back-end to store in a database or even return a special message based on their time. However, I'm not too sure how to begin. Would anyone happen to have any idea on how to do this? Thanks in advanced! Hello all, I need some help here. I'm new to HTML 5 and I'm not sure how to convert my cookie script over to HTML 5 LocalStorage. If anyone could help, I would appreciate it greatly.

document.body.setAttribute("orient",orient);
setTimeout(scrollTo,0,0,1);
}
$(window).unload(function() { // On page unload
$('.remember').each(function() { // Save each value to expire in a year
$.cookie(this.id, this.value, {expires: 365});

I am working on a Phonegap app that sends emails that consist of form data that is filled out within the app. I need my app to send the emails which I have sorted out. The second part of the app needs to store the email subject of all the mails that are sent in local storage and then in a separate function needs to output all the saved data and send it. I will post my full code below and comment the important bits. Code: function sendMail(imageURI, click){
var d = new Date();

var agent = $('#agent').val();
var depot = $('#selection').val();
var date = $('#free').val();
var newURI = imageURI.replace("file:///storage/emulated/0/DCIM/Camera/","");
/* -----> the variable that needs to be stored */ var newFileName = 'N' + result + '_' + agent + '_' + todayDate + '_' + newURI + '_' + depot + '_' + date;
/* -----> storing the variable */ var temp = localStorage.getItem('newFileName');

my problem is that instead of outputting all the sent subjects that have been stored like so: "subject 1, subject 2, subject 3, etc..." it is outputting it as the latest mail that was sent, i.e. "subject 3, subject 3". I have no clue why this is going wrong or how to fix it... any help would be greatly appreciated.

Though I admit I don't see why your code won't work. It just causes a bunch of unneeded overhead. ********** COMMENTARY: I think your dates will be unreadable by humans. var mon = d.getMonth(); That will get a ZERO for January, 1 for February, etc. For human readable, you should do var mon = d.getMonth() + 1; Hello, I apologize if this is not in the right forum as part of my question may not be reated to javascript but I have the following problem(s). I am attempting to make a website that has three pages: index.html customize.html home.html The index page needs to have an onLoad script that does several things: 1. Checks whether the browser supports localStorage and branches to either LSYes() or LSNo() accordingly 2. LSYes has to check whether a value of NY=True or NY=False has been set in local storage. If neither has been set it redirects to customize.html, otherwise it redirects to home.html. 3. LSNo has to perform a similar check and redirect as LSYes by checking for a cookie containing the appropriate value. The customize page has to have an onLoad script that detects whether localStorage is supported and somehow be able to pass that value to another script that is called later on from a form on the page. It also has to have another script that is called from rhe form that can handle any/all of the following conditions: 1. Checking a zipcode entered in the form against a list of NY zipcodes to determine whether the person lives in NY. 2. Save the value of NY=True if it finds a match or NY=False if it doesn't in either localStorage or a cookie based on the results of the onLoad script. 3. Allow the user to clear any values that may be saved and save new values if the user moves in or out of NY. The home page needs to likewise detect whether localStorage is supported. If localStorage is not detected it has to: 1. Check for either NY=True or NY=False in the cookie 2. Change the expiration date on the cookie to one year from the current date even if the cookie has not expired. 3. Completely hide certain sections of the page if it detects a value of NY=false or if a person navigates to the page without NY value being set but show them if NY is set to true. If localStorage is detected it has to perform similar functions using localStorage. In each case, if the browser supports localStorage that is to be used instead of a cookie. There are several things this site needs to do that are beyond my current skill levels. 1. localStorage detection 2. Comparing a zipcode entered on the form to a list of NY zipcodes without making the script huge and slowing down page loading. 3. Automatically changing from index to either home or customize based on whether localStorage has been set for the site. 4. Hiding or showing sections of a page based on a value in localStorage. I have an idea how to do some of this with a cookie but when I try it it acts like no cookie is present even though I know it is so I am not sure what I am doing wrong there. I have been trying to teach myself by putting parts of various scripts that each perform part of what I need together but this approach isn't working right. Thanks for your help Anello Hi all, I've been experimenting with Local Storage. I can do things like this just fine: localStorage.setItem('variable_name', variable_value); // write a value var variable_value = localStorage.getItem('variable_name'); // read a value localStorage.removeItem('variable_name'); // delete a value But if I do this: var object = { width : w, height : h }; ...then place it in local storage, reading it back gives me a TEXT STRING that says "[Object object]" and not the actual object. I would like to be able to store multiple values in one object, but it doesn't seem to work. I also tried to store a variable obtained with "document.getElementById" and when read back it just says [HTMLDivElement] (something like that) instead of the actual element. Am I doing something wrong, or does local storage not support objects? (btw, tested on FF 3.6). Thanks! -- Roger Howdy So i am working on a piece that using local storage and saves them to an un ordered list. I have been using Chrome for the console and inspector abilities and it has been going well. I've tested it before in Safari and Opera and I know it works. However, in Firefox (and IE but I don't care about that) I am getting a console error. Here is the code being executed: Code: var i=0;
while (localStorage.key(i) != null)
{
var values = localStorage.getItem(localStorage.key(i));
values = values.split(";");
$("#logscreen").append("<li class='arrow logname'><a href='#' class='direct' onclick='...'>" + values[0] + "</a></li>");
i++;
}
There is some jQuery thrown in there but basically it says, test for a localStorage key of i, if it is not null create the list item, add one to i and repeat. I am getting the following error in firefox only: Index or size is negative or greater than the allowed amount" code: "1 [Break on this error] while (localStorage.key(i) != null) Any ideas folks? So. When I save a boolean to localStorage It converts it to string. PHP Code: localStorage["fixedBackground"] = document.getElementById("fBackground").checked; And that saves a 'true' or 'false' string. So to convert it to a boolean value, in the 'restore options' I use the function 'toBool' PHP Code: function toBool(str) { if ("false" === str) return false; else return str; } PHP Code: var value = localStorage["fixedBackground"]; if (null != value) document.getElementById("fBackground").checked = toBool(value); And that works just fine. However, I want to recall this saved data in a javascript. I want an PHP Code: if (value = true){ document.getElementsByTagName('body')[0].style.backgroundAttachment="fixed"; } But I can't get a 'toBool' type of function into that statement This is my method of retrieving the data: PHP Code: var port = chrome.extension.connect({name: "knockknock"}); port.postMessage({get: "fixedBackground"}); port.onMessage.addListener(function(msg) { //Set bgimage attachment javascript:value=msg.value; which makes the full if statement: PHP Code: var port = chrome.extension.connect({name: "knockknock"}); port.postMessage({get: "fixedBackground"}); port.onMessage.addListener(function(msg) { //Set bgimage attachment javascript:value=msg.value; if(value = true) { document.getElementsByTagName('body')[0].style.backgroundAttachment="fixed"; } }); any ideas? Hey there. I've recently written a small javascript library that creates a unified interface for localStorage and sessionStorage. The code is here http://github.com/AndrewLowther/StorageItem I'm looking for people to give me feedback and to help me work on it should you so wish. Feedback is most welcome! Not sure if this is possible in javascript: I'm looking for two different dates (bill date and due date) on an invoice that are captured by OCR. If one of them exists, but the other does not, I want the empty field to be 14 days before (or after) the other. For example: if the bill date is 7/27/2010 and the due date was not captured, I want to set the due date as 8/10/2010 (14 days after the bill date). If the due date was captured as 8/10/2010, but the due date is blank, I want to assign the bill date as 7/27/2010 (14 days before the due date). if both dates have values, do nothing. Thanks. I have a drop down menu where people can select a month, day and year. Based on their selection, I want to show them an image. If their selection is >= July 26, 2010 but <= July 25, 2011, show the red image; If their selection is >= July 26, 2011 but <= July 25, 2012, show the white image; If their selection is >= July 26, 2012 but <= July 25, 2013, show the blue image; If their selection is >= July 26, 2013 but <= July 25, 2014, show the yellow image; I don't know how to compare a selected date to a range of dates like this. Hi, I need to add days to a date in javascript, My requirement is as follows: Date is coming from a textbox. eg:- 26/07/2010 days from this statement var day1=document.getElementById('<%=HiddenDate.ClientID %>').value; an eg:- if the date is 28/01/2012 and days Needed to be added=5 the added date should be 02/02/2012. Can anybody help me? Thanks Jamuna Hi, I've inherited a Form which calculates a future date based on a calculation and then inserts today's date and the future date into a database. The day part of the date is formatted as a number. This is fine, but up to 9 the numbers display in single figures with no leading zeros. I want them to display leading zeros (e.g. 01, 02, 03, 04, 05, 06, 07, 08, 09, 10, 11... 30, 31) So; 1/12/2010 is NOT wanted 01/12/2010 IS wanted The inherited code originally set the Month names as "Jan", "Feb" etc, and it was easy to kludge these to 01, 02... 12, but I suspect there's a more elgant solution to this as well, this bit of the code works so it's not as vital to neaten this but my database needs dd/mm/yyyy format (it's a third party email program). Code: </script>
<script type="text/javascript">
var todaysDate = new Date();
function updateExpiryDate(){
var weeklyMileage = document.getElementById('AvWeeklyMileage').value;
var expiryDate;
var weeks = 0;
var expiryDateString = '';
if (!isNaN(parseInt(weeklyMileage))){
weeks = 700/weeklyMileage;
expiryDate = new Date(todaysDate.getTime() + (1000 * 3600 * 24 * 7 * weeks));
var expiryDateString = expiryDate.getDate() + '/' + getMonthString(expiryDate.getMonth()+1) + '/' + expiryDate.getFullYear();
document.getElementById('expiryDate').innerHTML = expiryDateString;
document.getElementById('ShoeExpiryDate').value = expiryDateString;
} else {
document.getElementById('ShoeExpiryDate').value = '';
document.getElementById('expiryDate').innerHTML = 'Please enter a valid weekly average mileage'
}
}
function getMonthString(monthNumber){
var monthString = "";
switch(monthNumber){
case 1:
monthString = "01";
break;
case 2:
monthString = "02";
break;
case 3:
monthString = "03";
break;
case 4:
monthString = "04";
break;
case 5:
monthString = "05";
break;
case 6:
monthString = "06";
break;
case 7:
monthString = "07";
break;
case 8:
monthString = "08";
break;
case 9:
monthString = "09";
break;
case 10:
monthString = "10";
break;
case 11:
monthString = "11";
break;
case 12:
monthString = "12";
break;
default:
// do nothing;
}
return monthString;
}
function setTodaysDate(){
var todaysDateString = todaysDate.getDate() + '/' + getMonthString(todaysDate.getMonth()+1) + '/' + todaysDate.getFullYear();
document.getElementById('todaysDate').innerHTML =todaysDateString;
document.getElementById('DateOfPurchase').value = todaysDateString;
}
Can someone point me in the right direction please? Using Adobe Form Javascript validation, how would I do this code for Visual Basic in Javascript (non web) Code: If PurchaseDate.Value > Date Then
MsgBox ("PurchaseDate cannot be greater than Today's Date!")
Cancel = True
End If
Something along these lines but this isnt working: Code: If (PurchaseDate.Value > Date) Then
{
app.alert ("Purchase Date cannot be greater than Today's Date!");
}
Thanks Hi all I am trying to create a code which stores information about songs The information to be stored are : song ID song name song artist song URL So far what I've done is create an empty array with four properties The code asks the user to enter information and then displays them However i'm having difficulty figuring out how to insert all the information entered in the array. For example if information about 3 songs were entered, how can I insert all of them in the array I created. After storing the information, I want to be able to search for songs by their ID. When I wrote the function to do this, if lets say I entered two songs one with S1 as ID and one with S2 as ID, I type S1 in the search box, but it doesn't return anything. However if I enter S2, it returns the information of the track with this ID, which makes me think that entering information for a second song overwrites the first one This is my code so far: <html> <body> <h1>Tracks and Artists</h1> <script type="text/javascript"> function request(tracks) { for (var i=0;i<2;i++) { tracks.trackID = prompt("Enter track ID") tracks.trackName = prompt("Enter track name") tracks.trackArtist = prompt("Enter artist name") tracks.trackURL = prompt("Enter track URL") alert(display(tracks)) } } function insert() { function display(tracks) { return "Track ID: " + tracks.trackID + "\nTrack name: " + tracks.trackName + "\nTrack artist: " + tracks.trackArtist + "\nTrack URL: " + tracks.trackURL } var tracks = [{trackID: "", trackName:"", trackArtist:"", trackURL:"" }] request(tracks) </script> </body> </html> Hey All, I have completed most of a homework assignment that I am working on. I am able to .push desired elements into an array: Code: //Insert variable into the Array
function insertElem(){
//Insert and sort first array, but not second array
if(nameInput.value != ""){
studName2.push(nameInput2.value);
}
else{
alert("Value to be inserted cannot be Null");
}
//Refresh display area
clearAndShow2();
}
What I would like to do is be able to store and display the created array "permanently" until I decide to remove the elements. My current method to hold the elements, until the page is refreshed, is: Code: //Refresh second array
function clearAndShow2(){
nameInput2.value = "";
messageBox2.innerHTML = "";
messageBox2.innerHTML += "Groups: " + "<br />" + studName2.join("<br />") + "<br />";
}
I appreciate the assistance. Hey guys, I just recently started getting into JavaScript (2 days ago) after seeing how limited HTML and CSS by itself is, and I created a game where you have a certain amount of time to click as much as you can. The game works fine but the problem is with my leaderboard. I want to be able to store the high scores and names so that everybody see's the same thing. I know cookies save data but is that only clientside? All I need to do is save 6 variables so that the leaderboard is always updated. Any help would be appreciated. Thanks. hello there this is in vb script. but i dont where to post it. can any one hlep me out plzz I need to check if the date entered by user is within 5th date from current date.

ok so what im trying to acheive is that when a user clicks on either of the rating links, a js function is run which gets the li value and then sets a value of a varible to match the li value and then i want to add that value to the hidden userrating form input and set the value of <li id"current" width value to the same value but as im sure youve noticed from my code it isnt working. any help it greatly needed and appreciated, thanks Luke Hi everyone, The website that I am trying to create has a couple of drop down lists. I want a variable to store the value (text) of the data field selected from a particular drop down list. Let me explain this with an example: If a dropdown list has data fields like (aa, bb, cc, dd, ee) and if a user selects the option 'bb' , then there should be a variable that stores the text 'bb'. I am using the following piece of code. Can you please take a look at it to tell whether I am doing the correct thing or not. Firstly, the HTML code that generates the drop down list on the page. This works fine. Code: <b> Student's Profession</b> <FORM NAME="Profession"> <SELECT NAME="Student’s Profession"> <OPTION VALUE="k1">Select <OPTION VALUE="k2">Engineer <OPTION VALUE="k3">Doctor <OPTION VALUE="k4">IAS <OPTION VALUE="k5">Lawyer <OPTION VALUE="k6">CA <OPTION VALUE="k7">IAS <OPTION VALUE="k8">Engineer + MBA <OPTION VALUE="k9">Family Business <OPTION VALUE="k10">None of the above </SELECT> </FORM> [Then I have declared a function in JavaScript that stores the value of the data field selected in a particular variable (sel_student_profession). I am not sure about the parameter. Should I simply write 'dropdown' or write the form name? (Profession). Or something else? Code: <script type="text/javascript">
function Selected_profession(dropdown)
{
var myindex = Profession.selectedindex;
var sel_student_profession = Profession.options[myindex].text;
return sel_student_profession;
}
</script>
And then at the end of it, if I want to know the value (text) of the data field selected, I call the function. Right now, I am calling the function as follows: Code: var student_profession = Selected_profession(Profession); So, if the user selects "engineer" from the drop down list, student_profession should store "engineer". Am I doing it the correct way? If not, I would highly appreciate any sort of help. Thanks a lot! |
