JavaScript - Storing Variables Serverside?
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. Similar TutorialsHi 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> 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! 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. 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! 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! I'm integrating a JavaScript typing tutorial to my website. But I'm not able to store the value to the database. In the below code you can see the speed is updated in a html span. The id of the tag is speed(<span id="speed"></span>). This code will automatically update when user start typing. I want to update this to a database when user press submit button. But i cant able to. Is there any way to input the speed to database ? Please go through the below code and suggest me what i can do....? Code:

hey guys im not new to javascript but arrays still confuse me exspecialy when put into loops ok say i had 2 arrays i have used jquerry to extract a question lets say this is the question How long is a piece of string? the answer is for this example infinite so what i want to do is search the question trough a array with 21984 and more in the future when it finds the match it then looks at the answers array at the same array length as where the question was found then sends the answer to a variable for later use could someone give me a example on how to do this please? Hi all, ok firstly i know all but nothing about javascript and you prob about to see the worst attempt eva at trying to understand it ok so here is my js code Code: <script language="javascript">
function selectElement(idElement)
{
var ratingval = "";
liElement = document.getElementById('sel'+idElement);
lirating = document.ratingform.userrating.value;
if(liElement == "sel1")
{
raingval = "1";
lirating = "1";
}
if(liElement == "sel2")
{
raingval = "2";
lirating = "2";
}
if(liElement == "sel3")
{
raingval = "3";
lirating = "3";
}
if(liElement == "sel4")
{
raingval = "4";
lirating = "4";
}
if(liElement == "sel5")
{
raingval = "5";
lirating = "5";
}
}
</script>
and here is my html code Code: <form name="ratingform" action="" method="post">

</form>
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 Basically I am being restricted by a third party program that manages my email list. When a person signs up for my website it first adds them to my external email list and then to my MySQL database. In order to do this you have to pass the information of the form to the next page where you can "display" it. Nothing except this display function seems to work. So what I am trying to do is take what is outputted by this display button and store it in a javascript variable. Then transfer this variable to a form which will auto submit and start the PHP registration. I need help pulling the output of the script, right now I can either get an undefined or the entire HTML code. Is there another option?

Hey all, have a bit of a problem. I'm trying to store a variable in Javascript that consist of user input that may include both quotes and apostraphes (amongst any other stuff). Currently looks a bit like this: Code: <script>
var importantNote = [[Note]];
if (importantNote != "" && importantNote != " ") {
var importantNoteOutput = "<div class=\"important\"><h3>Important Note:</h3> [[Note]]</div>";
document.write (importantNoteOutput);
}
</script>
Obviously, when [[Note]] (another variable pulled through a seperate program to create complete code) contains ", it doesn't go so well ('[[Note]]' solves that, but creates same issue with any plurals ). I *could* get end user (probably me) to always ensure anything entered in this field (and few others used in a similar way) contain escaped characters, but this isn't preferable. Preferably, I'd like a way of escaping an entire string automatically, eg. encode([[Note]]) - though that doesn't seem to work. Any quick tips? FWIW, I don't think I can use php, or much else for the task. Pretty much stuck with html and javascript. Thanks I'm not sure why my code is working. I think it maybe because of incorrect storage of multi arrays. Can someone please take a look. Please provide advice on how to improve. Code: <script type="text/javascript">
var route ="Route A - Toronto to Barrie";
var jon, don;
var businfo=[
//[destination/route, pricing, number of available tickets]
["Route A - Toronto to Barrie", 10.10, 38],
["Route B - Toronto to Peterborough", 12.30, 38],
["Route C - Toronto to Montreal", 42.00, 38],
["Route D - Toronto to Thunder Bay", 114.30, 38]
];//end multi-array businfo
function determineRoute() {
for(i=0; i < 5; i++){
if (route === businfo[i][0]) {
jon = businfo[i];
break;
}
}
}
function setNumOfTick(ticketsordered) {
don = jon;
var tickettotal = don.splice(0,1);
tickettotal -= ticketsordered;
don.splice(0,1,tickettotal);
return(2);
}//end setPrice
alert(setNumOfTick(35));

Hello, 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 Noob here. Please bear with me.http://www.codingforums.com/images/smilies/tongue.gif <span title="this is the title">....</span> I need to use variables for the title instad of text. Please advise. Thank you. I wrote a script: when the same button is clicked for the first time, it should give a message "Hello World", for the second time "hello Earth". The script is not working. I don't want anybody to re-write the script, but to look at how i define variables and tell me where I am wrong. I think, this is where the main error is. my current script just outputs the message "hello world". my assumption is that functions can alter the value of a global variable. Thank you very much.

hello i am editing a javascript game and im trying to get a heading (h1) to display the value of a variable in a javascript function however everything i have tried always causes an error. Any help will be apreciated. Hi All Please could any one shed some light on the values of thirdVar fourthVar and fifthVar. Am i correct to say that value of thirdVar is o cromwell Any help and explanation would be great thanks. var firstVar = 'oliver' var secondVar = 'cromwell' var thirdVar = firstVar.charAt (0) + '. ' + secondVar var fourthVar = thirdVar.length var fifthVar = 'The last character is' + thirdVar.charAt (fourthVar) + '!' I hope someone can help me! I have a website that sells a product through a third party merchant - ie a customer clicks my "buy now" button and they are transfered to the merchants payment processing page. once the transaction is complete the customer is sent back to my thank you page where I give them some extra stuff for free. All pretty normal I guess. The problem is this - The merchant sends back some url parameters when they transfer the customer to the thank you page and I would now like to use the "customer name" parameter to personalise the thank you page to test if this makes any difference to my return rate. Now, whilst I am not a complete newbie I haven't got a clue how to achieve this. What I want to do is have the page display: "Hello [customer] .....etc..." The customer name parameter is passed as "cname" and is one of about a dozen passed seperated, presumably, by "&" Thanks for any help! Paul Hello, I am using javascript to dynamically edit a form and have run into some problems. In this excerpt of code "x" is already defined, "num" is already defined, and "eval(q)" is just pointing to the proper field in the proper form. Code: eval(q).onkeydown=function onkeydown(event)
{
checkLength(event,x,num,5);
};
Now the problem is, it is literally calling the function with "x" and "num" instead of their values. I tried "eval(x)" and "eval(num)" but that literally calls it with that whole statement as the parameter. How can I call this with the actual values inside of x and num? Thank you. Hello everyone. I am new to this forum and hope to become a good addition. Thanks in advance to whom ever might help. I am having trouble concatenating variables in the alert box. The alert will basically be: Sum of the numbers from 1 through 5 is 15. But the 5 is the var = userEntry and the 15 is the var = sumOfNumbers. Of course, the numbers 5 and 15 will be replaced by the userEntry and the calculated sumOfNumbers. I have been able to make the first variable work, but cannot get the second one. For example: alert (" Sum of the numbers from 1 through " + userEntry);. I just cannot figure out how to concatenate a second variable into the message. I hope I am making sense. I am new to javascript and working off of Murach's Javascript and jQuery. Thanks again! I am building a search function for a sermon blog on squarespace. The format url for category search is www.mysite.org/blog?category=... I have drop down menus and a datepicker but need to figure out how to get java to build the url and redirect to it. The output url should look like http://www.mysite.org/sermons?catego...+mybook+mydate. Any help would be greatly appreciated. Here is my java so far. Code: function search() {
var myRootSite = 'www.mysite.org/sermons?category=';
var myNewTitle = document.getElementById('myTextField').value;
var mySpeaker = document.getElementById('mySpeaker').value;
var myService = document.getElementById('myService').value;
var mySeries = document.getElementById('mySeries').value;
var myBook = document.getElementById('myBook').value;
var myDate = document.getElementById('myDate').value;
if (myNewTitle == 0 && mySpeaker == 0 && myService == 0 && mySeries == 0 && myBook == 0 && myDate == 0) {
alert('Please enter some search criteria');
return;
}
var title = document.getElementById('title');
title.innerHTML = mySpeaker;
}
