JavaScript - Duplicate Count
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. Similar TutorialsHello 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>

disregard...i got it
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
Greetings and salutations. My text and what I have been researching on the internet has not been very helpful in determining the code that I need to prevent a user from entering his/her information more than once.

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. Hello Guys, im writing a big page with several different elements in it, and im stuck trying to duplicate a script. first one works "tab b" click each 'icon' and a .png file appears above it to show its selected. "tab c" same script and code seems to only work for first icon, and switch off when clicked on the others. been staring at this for sooooome time now, please can someone see what i have done wrong, as i dont really understand the code im using, im just a beginner. url is http://www.zakscustomcues.com/module...builder2.0.php much appreciated. steve 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.

Hi Experts, I have an online application form that a member submits to register with our organization. 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>

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... I've been looking everywhere for a script that counts up from 1 to 10, but can't find anything. I even searched the forums. Basically just something that starts from 1 and then replaces itself with 2, and so on. Thanks! Hi, I am not a Javascript programmer and I am facing some barriers. Maybe some of you could help me. I would need a script that can be used to count down until any given date with hour, minutes and seconds. For example: Quote: September 10, 2009 16:02:00 Bob Kuspe Deleted
