JavaScript - Javascript Count Checker
I have a js counter which keeps track of how many chars are in a field on an asp form. When the user clicks a button further down in the form, the form generates more fields. This also causes the js counter to reset to its original value, as the page is 'reloading' in a way. How can I check this value and keep it the same when the user clicks this button? I am including the code I have, if anyone has any ideas/suggestions thanks
javascript Code: <asp:Content ID="Content1" ContentPlaceHolderID="headContent" runat="server">
<script type="text/javascript">
//limit of chars
var lim = 128;
function count(a) {
//difference count
var dif = lim - a.value.length;
while (dif < 0) {
a.value = a.value.replace(/.$/, '')
dif = lim - a.value.length;
}
//display difference count
document.getElementById('myspan').firstChild.data = dif;
}
</script>
counter in code Code: <asp:TextBox ID="txtHeadline" runat="server" Width="600px" MaxLength="128"
CssClass="VariableText" onkeyup="count(this)"></asp:TextBox>
</td>
<td valign="middle" width="160px">
<asp:Label ID="Label14" runat="server" Font-Bold="True" Font-Names="Tahoma" Font-Size="8pt"
Text="Characters Remaining: " Width="130px" CssClass="LABEL"
Height="16px"></asp:Label>
<span id="myspan" Font-Names="Tahoma" Font-Size="8pt">128</span>
button Code: <asp:Button ID="btnInitializeTemplate" runat="server" OnClick="btnInitializeTemplate_Click"
Text="Initialize Template" CssClass="LABEL" />
i have tried Code: <asp:Button ID="btnInitializeTemplate" runat="server" OnClientClick="return count(document.getElementById('txtHeadline'));" OnClick="btnInitializeTemplate_Click"
Text="Initialize Template" CssClass="LABEL" />
it compiles but the value remains reset. any advice on what im doing wrong? Similar TutorialsI badly need a Javascript syntax checker for my Javascript. Any suggestionss will be gratefully received.

======================================================= Hi I'm looking for ways to limit the textarea input, I dont want people to enter hundreds of lines cause, i only want them to enter max. 10 lines. I've looked at several javascripts (cause the problem only can be solved by javascript), and came up with this script: http://javascript.internet.com/forms...-textarea.html . It works great and even has a counter how many characters are left to type in. However when I copy paste something, the 'counter' doesnt adjust right away...it does when I try to type in something extra though. Is it possible to make the counter adjust automaticly whenever there is pasted ? I guess you guys have to test to see what I mean. Thanks in advance !! Hi, I am new to programming and I am trying to write a code that will time how long it takes for you to write a word. First you input the word you would like to write, and than after you have pressed enter I want the program to "feel" when you start writing the word, at that point the timer should start. And then it shall know when you have completed the word and in that moment stop the timer. I have a built a timer that works fine, see startCounter() but i want it to be executed as i described above... This is the code: Code: <div>
<div class="inputBox">
<input id="textBox" type="text" placeholder=" What word would you like to time?" onKeydown="Javascript: if (event.keyCode==13) hello();">
<input type="button" value="RushWrite" id="Btn" onclick="hello()"></input>
<script>
function hello() {
if (textBox.value != "") {
var wordInput = document.getElementById("textBox").value;
document.getElementById("textBox").placeholder=" Let's RushWrite: "+wordInput;
textBox.value = "";
document.getElementById("Btn").value="GoGo!";
document.getElementById("time").innerHTML="00.00";
};
}
</script>
<button id="time" type="text"></button>
<script>
function startCounter(){
var counter = 0;
setInterval(function () {
++counter;
document.getElementById("time").innerHTML=(counter);
}, 1000);
};
</script>
<script>
</script>
</div>
</div>
Thankful for any advise! I have used this script successfully: http://www.javascriptkit.com/script/...2/refer2.shtml However, is there a way to block the following work-around (example only): http://www.their-url.com/redir.php?u...ww.my-url.com/ The redir.php makes it possible to get past the script. Hi, I have good script Code: <script type="text/javascript">
function chkcontrol(j) {
var total=0;
for(var i=0; i < document.form1.opt.length; i++){
if(document.form1.opt[i].checked){
total =total +1;}
if(total > 11){
alert("No more than 11 please")
document.form1.opt[j].checked = false ;
return false;
}
}
}
</script>
But this script works only If I have: <input type="checkbox" name="opt" value="1" onclick='chkcontrol(1)'>Opt 1 <input type="checkbox" name="opt" value="2" onclick='chkcontrol(2)'>Opt 2 I need to proces this form with PHP so, when I change opt to opt[] (<input type="checkbox" name="opt[]"..) script doesnt work anymore. Couldnt find any script for it, so help me if you can. Thank you hi i want to create one java code that do this : 1-one counter is counting 20 to 0. 2-if counter 0 then choose random string between "click one" , "click two" , "click three" and show it. 3-in other table we have three button that name`s are "one" , "two" ,"three". 4-for continue page user must click true button,if user click false button alert "wrong". thx Visitors enter information in textarea's and form fields and I wish to allow them to have this spell checked before submitting. What methods are open to me to do this. Hello, I'm building a simple custom dropdown menu for a web-site so that I can control look and feel as well as the behavior of an iframe. I've set it up so that when the user clicks on any of the menu's active components, an "if" sequence in the clickHandler() function is activated that gets the element's class. If the event occurred on a dropdown option, the event-target id is checked, and the appropriate function is called. At least this is how it's supposed to work. All of the drop-down options have been assigned the "dmo" class. When I test the menu and click on other elements, it works fine. But when I click the "dmo" drop-down options, nothing happens. Firebug and IE Explorer Developer Tools both show no errors, but on clicking a dropdown option, the correlate code doesn't run at all, and after hours of head-banging, I have no idea why. I need help on this one. Here's the code. Code:

1 down vote favorite I do have the countdown script (see link below) to display the time between current time and the date given in real-time. 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'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 Hi, I want to do a redirect count so that the user can see the count going down. for example, I want them to be able to see the following. You will be redirected in 5 seconds. The user should be able to see the count going down from 5 to 4 to 3 to 2 to 1 and then they are redirected. I can get the page to redirect after 5 seconds but I want the user to be able to see it count down. Thanks in advance for your help 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. Deleted
hi i am new to javascript. i make a mcq quiz website in one of server side script. now for that website i want to make count down timer so when that quiz starts the user will have 5 minutes to complete that quiz if use does not able to complete quiz in given time then quiz should disable and shows the user score how can i achieve this I have a script that almost does what I need: a simple counter that counts inmigrants remmittences to their home countries.
