JavaScript - How Can I Find Duplicate Number And Print Them Out?
Hi there
It's huge problem for me but I don't think it is for many of you here. I have been asked at the college to make a manual lottery checker using javascript, but I found lots of problem during the coding. To make it more clear it's about 3 players they always play the same set of 6 number between 1 and 49. the players enter manually the winning number using a prompt which popup when you open the page (No button required for this, just simple prompt). each time you type duplicate number an alert tells that this number been entered, when the six number been successfully entered will ask for the bonus ball the same way but it should between 1 and 49 as well. When this done the program print out for each player the much numbers. This my peace of coding but I stucked in many bits in it. I need your knowledge guys in javascript to fix this for me. Code: <html>

//Fix the lottery Numbers between 1 and 49
while (drawNumber[i]<1 || drawNumber[i]>49)
{
drawNumber[i] = prompt("The lottery Number should be between 1 and 49"); // to insert Prompt insteat the Alert
}
if (drawNumber[i] = drawNumber) // if statement to be checked again
{
alert('You already entered this number');// if statement to be checked again
}

Similar TutorialsNoob here! I'm doing a little project where i need to take a number (lets say 6), and then I need to find out witch numbers 6 can divided with that equals to a whole number. Any ideas how i can do that? This is what i got in my mind so far: myNum/num === wholeNumber I then need a variable "num" that count all whole numbers from 0 to myNum and a variable "wholeNumber" that works as all whole numbers from 0 to myNum. I really hope you can help me out, thanks If i have 4 vars var one = 29.1 var two = 5.4 var three = 12.4 var four = 15 how can compare all 4 and find the smallest? in this case the result would be two Basically I want to factor a number and select the two closest numbers to the middle of the factors for example: 20 factors to 1, 2, 4, 5, 10, 20 I want it to return 4 and 5 If the number is has an odd number of factors (has to be a perfect square) I want it to select the middle number and say it twice for example: 64 factors to 1, 2, 4, 8, 16, 32, 64 I want it to return 8 and 8 Would I use an array or what? My code should probably look like: PHP Code: x = //Factors array y = //number of items in x if (/*y is even*/){ i = y/2 i2 = i+1 a = [i] b = [i2] } else{ i = //somehow the center number? i2 = i a = [i] b = [i2] } I have a function below where every time a question is submitted, it will add a new row in the table with a textbox which allows numbers entry only. My question is that I don't know how to code these features in this function: 1: I want the text box to be between 0 and 100, so if text box contains a number which is above 100, it will automatically change the number to the maximum number which is 100. Does any one know how to code this in my function below in javascript: Code: function insertQuestion(form)
{
var row = document.createElement("tr");
var cell, input;
cell = document.createElement("td");
cell.className = "weight";
input = document.createElement("input");
input.name = "weight_" + qnum;
input.onkeypress = "return isNumberKey(event)";
cell.appendChild(input);
row.appendChild(cell);
}
I am trying to figure out how to make a random number I can plug into a script count down from that number at certain times of the day until it reaches 0. I would like it to reset itself at midnight every day. I'm trying to make it work with a script I found on here that resets itself at midnight every day. So instead of it counting down too fast, it would count down to the next number after a randomly generated number of minutes until it reaches 0. But it wouldn't necessarily have to end at 0 at midnight. It could go from 845 to 323 at the end of the day at a slower pace. Is that possible?
When I used toFixed() method on a number, I thought that this method round a number to a specified approximation, but I got a surprising result, the number became string! 15.23689 .toFixed ( 2 ) ==> "15.24" So does it convert the number into string? Hello Guys and Gals, I have got my head around using the jquery validate and submit without refresh and implemented it successfully on a front end form. Now I would like to streemline backend updating by enabling submit without refresh for multiple items on a page, validation would be nice but less important. what I would like to do is something like adding 'here' to the function and 'this' to the form but im not sure how exactly. here is the code im using Code: <title>Untitled Document</title>
<script src='http://ajax.googleapis.com/ajax/libs/jquery/1.6.1/jquery.min.js'></script>

I would like to count how many duplicate values I have in an array. My below attempt doesnt count the duplicate values: Code: var ct = 0;
for(var i = 0;i < myArray.length;i++)
{
var myData = getData[i].city;
if(myData == myData)
{
ct++;
}
alert("Total Count = " + ct);
}
Please advise the best way to do this. disregard...i got it

I have created a new web page to link the duplicate cookie too, titled doubleinfo.html. This is what I am using to let the user know that their information has already been entered. My text is telling me that I need to look for a nextform() function, but I didn't have to write one so what would I need to do, if anything, to start the document.cookie = "name" codes? Any help would be greatly appreciated, thanks in advance. Is there a method or a way to duplicate the text typed in one textarea to another, with onkeyup or onchange? The problem I'm facing is with FCKeditor. Two textareas with loaded templates and the text has to be manually copied and pasted when changed. Code: <form action="" method="post" name="form1" id="form1"> Subject:<br /> <input type="text" name="subject" value="Subject" size="32" /> <br /> Main Article:<br /> <textarea name="content" cols="50" rows="10"> <?php echo $row['article']; ?> </textarea> <br /> Text version:<br /> <textarea name="content_text" cols="50" rows="10"> <?php echo $row['article']; ?> </textarea> <input type="submit" value="Send" /> </form> I may be going about this all wrong? Send newsletters, it all works - not sure? do I need the second texarea. OMG, Check out the background on this site... http://paulirish.com/ how would I even start to rip that for use on my own site? I'll pay someone $15 on paypal if they can make a css and js file that I can just link too and have this background

However I want to make sure that the member submits only one application form per session year. Is there anyway I could setup a java script that lets the member know that they have already submitted their application when they try to re-submit. The current setup lets them submit many applications which I am trying to prevent. Any help is greatly appreciated. Thanks Vinny Hi everyone, now I need to add items into a dropdown list, and the items would be sorted alphabetically and it does not allow duplicate items to be added. Can anyone help take a look and see what's wrong with my code? Javascript Code: function addAnotherOption()
{
var newItem = document.getElementById("Text44");
if (!newItem.value == "")
{
var answer = confirm ("Are you sure you want to add? ")
if (answer)//if answer is true
{
var lst = document.getElementById('comboBox'); // listbox control id
// Now we need to create a new 'option' tag to add to MyListbox
var newOption = document.createElement("option");
newOption.value = newItem.value; // The value that this option will have
newOption.innerHTML = newItem.value; // The displayed text inside of the <option> tags
for (var i = 0; i < lst.options.length; i++)
{
arrTexts = lst.options[i].text;
if (arrTexts.toLowerCase() == newItem.toLowerCase())
{
alert ("That option is already included in the list - please enter another item.");
return false;
}
else
{
// Finally, add the new option to the listbox
lst.appendChild(newOption);
//sort items in listbox in alpha order
arrTexts = new Array();
for(i=0; i<lst.length; i++)
{
arrTexts[i] = lst.options[i].text;
}
arrTexts.sort();
for(i=0; i<lst.length; i++)
{
lst.options[i].text = arrTexts[i];
lst.options[i].value = arrTexts[i];
}
}
}
}
}
else
{
if(newItem.value == "")
{
alert("Key something to textbox please.");
}
else
alert("Cancelled.");
}
}
HTML Code: <input id="Text44" type="text" />
<input id="Submit22" type="submit" value="Add" onclick="addAnotherOption()" /><br />
<select name="combo" id= "comboBox" style="width: 323px">
<option value="H">Hearts</option>
<option value="D">Diamonds</option>
<option value="C">Clubs</option>
<option value="S">Spades</option>
</select>
Hi, I would like to prevent the addition of duplicate items in the following situation. Firstly, I have a listbox with a few options such as Code: <select id="listbox" name="listbox" multiple="multiple" style="width: 580px;">
<option>Java</option>
<option>PHP</option>
<option>Perl</option>
<option>Javascript</option>
<option>C#</option>
<option>Powershell</option>
</select>
Next, I have a submit button with a textbox. The user will be able to submit new options into the listbox via the textbox and submit button. Therefore, I need to prevent the user from entering duplicate items into the listbox. How should I do? The following code is used to add items into the listbox. Code: function addItem()
{
var lst = document.getElementById('listbox'); // listbox control id
var newItem = prompt("Enter New Item","Enter Value Here");
//Option object is created for every option in a selection
//new Option([text[, value[, defaultSelected[, selected]]]]) // Syntax
if(newItem == null)
{
return false;
}
else
{
lst.options[lst.length] = new Option(newItem,newItem,false,false);
return false;
}
}
i've written a js function to find the difference between two dates. the format being used is dd/mm/yyyy hh:mm. The function returns correct value when give one set of values, but go wrong with another set. examples are given below. set 1 : Time 1 = 24/02/2011 09:30 , time 2 = 24/02/2011 16:00 Output is corret here. It gives 6 Hours & 30 Minutes (after converting the difference) set 2: Time 1 = 24/02/2011 09:30 , time 2 = 25/02/2011 16:00 Here, it gives 31 days, 6 Hours & 30 Minutes. My code is given below. Also the alert of dates display strange values. Don't know if it is timezone issue. I wonder what is going wrong here Code: function compareDateTime(frmtime,totime)
{
var date1 = new Date(frmtime);
var date2 = new Date(totime);
var diff = new Date();
alert(date1);
alert(date2);
diff = (date2.getTime()-date1.getTime());
if (diff<0)
{
alert("From Time cannot be later than To Time!");
return 0;
}
else if (diff==0)
{
alert("From Time cannot be equal with To Time!");
return 0;
}
else
{
return diff;
}
}
The returned diff value is broken down as following: Code: if (diff>0)
{
days = Math.floor(diff / (1000 * 60 * 60 * 24));
diff -= days * (1000 * 60 * 60 * 24);
hours = Math.floor(diff / (1000 * 60 * 60));
diff -= hours * (1000 * 60 * 60);
mins = Math.floor(diff / (1000 * 60));
alert(days+","+hours+","+mins);
return true;
}
Please Help... Hello, Below is the javascript I'm debugging (or trying to) but just can't see where the error is: The code should send a message "GOOODDD!!!" when the input box is empty (nothing typed in) and should send a message (BAAADD!!!) when a string of theee a's are typed in ("aaa"). The problem is that no matter what I type in the script ALWAYS sends me a "GOOODD!!" message. I guess it is a simple glitch but I just can't figure it out. I'd appreciate any help Thank You. Code: <script language="javascript" type="text/javascript">
<!--
function textCheck(that)
{
var mytext=document.getElementById("BLABLA")
if (mytext == "aaa")
alert("BAAAAADDDDD!!!!" + mytext.value);
else
alert(" GOOOODDDD!!!!" + mytext.value);
}
-->
</script>
</head>
<body>
<form id="form1" method="get" onsubmit="textCheck(this)" />
<input name="BLABLA"
size="3"
type="text"/> Input Data
<br/><br/>
<input name="Submit1" type="submit" value="submit" />
</body>
