how do you count the number of checkboxes that have been selected say I want more than 1 and less than 3 to be selected out of 5?
<script type="text/javascript">
if (document.formName.numberOfBlanks.checked >= 1 && document.formName.numberOfBlanks.checked <= 3)
alert("test")
[code]...
I am trying to figure out the best way to count how many checkboxes were selected. Suppose I have the following HTML:
Code:
<form name="myform" id="myformid">
<input type="checkbox" name="items[]" id="item0" value="One" />
<input type="checkbox" name="items[]" id="item1" value="Two" />
<input type="checkbox" name="items[]" id="item2" value="Three" />
[Code]....
But I don't think I can do it that way since I'm dumping it all into an array for processing.
I have a dynamic html. i'm trying to count the number of checkboxes checked.
For some reason this isn't working.
Code:
I have a form with checkboxes. I have the results being stored as an array, that gets sent to a mysql database.
how can i limit the number of checkboxes selected? I am looking for a max of 15 selections.
i've been able to set the max when the checkboxes are not stored as an array, but for simplicity storing as an array is the way i need to go.
Basically, I'm counting all the checked checkboxes and assign the count value to a hidden field in the form. <script language="JavaScript" type="text/javascript">
function KeepCount()
{
var count = 0
var max = document.getElementsByTagName('checkbox').length;
FOR( var x=0; x<max; x++)
{

I have a foreach loop that displays survey testimonials. The user is allowed to pick only 5 testimonials. Is there an easy way to disable the rest of the checkboxes once the selected item is 5? I was trying this in jquery but this is not doing anything.
<script type="text/javascript">
$(document).ready(function () {
var checkedcount = 0;
$('.chkItems').click(function () {
[Code]....
How could I count how many checkboxes are checked? There are around 100 checkboxes and I don't want the user to check more than 10.
View 5 Replies View RelatedI am stuck on something that is probably a straight forward issue. Just can't get my head around it.Basically I have a whole bunch of checkboxes and I want to count the number that have the same class (only when selected)Example:
<input type="checkbox" name="Paris" value="FR" />
<input type="checkbox" name="Marseille" value="FR" />
<input type="checkbox" name="Cardiff" value="UK" />
[code].....
<script language="javascript">
function checkall(){
var chkd=document.getElementById('ckbox').value;
num=form1.numberOfBlanks.length;
var i=0;
while(i<chkd.checked==true.length) {
alert("hellow");
i++=;
}}
</script>
This does not work.
I have two "series" of check boxes in a form. One named:
<input type="checbox" name="check_100[]" value="1" />
<input type="checbox" name="check_100[]" value="2" />
...and so on
and one named
<input type="checbox" name="check_101[]" value="1" />
<input type="checbox" name="check_101[]" value="2" />
...and so on.
I need to ensure that no more than 4 checkboxes from the first (100) series are checked simultaneously. I've managed to find some scripts that come close, but they all count all the checkboxes in the form instead of the specific ones that I'm interested in.
I want to count the characters in a string. The problem here is, the 'return key' i.e if 'enter key' should be counted as 2 instead as 1 character.
I tried few logics but none of them worked out. I tried with php ajax too. It worked fine in firefox but not in IE.
Here is the logic i used. When onkeyup call the js function.. which calls the php page by passing the string as encodeURIComponent(str).
Now, I took the string in php and counted the in the string and added the no of occurrence of to the string length.
My concern is, IE is returning 3 for return key instead of 2.
I want to know how to count to a number via jQuery. jQuery should get a value in a variable and then start counting to it in a fix time. for example the number is 500.67 then i should start with 1 and the add up until it reaches 500.67 in 5 seconds, so the final value is not visible at the begining but at the end. the numbers can b between 1 and about 1 million but it should always need 5 seconds to count to it (must not be always +1 but i should count smooth).

When I right click on a file and pick "openFile"from the context menu, the action only run once. But when I do this again, it runs twice. When I do this again, it run three times, and so on ... For some reason jQuery (or JavaScript) is counting the times I have clicked on the class '.file', and fires the action according to this number.

I have a piece of Javascript which i'm using to count the number of words in a textbox, which works nicely.
However the text called into that textbox is called dynamically from a database and the amount of words called into that box is ONLY shown when the user clicks on the textbox using onkeyup or I can create it when I use onClick.
is there anyway you can say on page load or something similar rather than having to click a box using onkeyup or onClick?
I have a php page that dynamically generates any number of text boxes.
To validate its input, I need to know how many text boxes are in the form.

I'm sure that's completely wrong but there has to be a way to count the number of elements in a form.

HTML Code:
I was wondering if anybody can provide me with high level suggestions as to how to do the following in javascript.I want to record the number of times a piece of javascript is run across multiple disparate machines.To do this I was thinking that the javascript should open javascript a webpage every time it is run. I can then count how many times that webpage has been called which in turn will be the number of times the javascipt has run. However I don't want the webpage to open in the users machine as this will be really annoying for the user.if you can think of a better way to complete the overall goal.
View 8 Replies View RelatedSo never done this one before so I am having a bit of a time trying to figure this one out.
Say I have a list of LI element and only a few of them have a inline style of display block, the rest have a display of none.
How would I go about looping through and dertmining the number of elements that have a display of block?
for(var m = 0; m < li.style.display.length; i++)
{
alert(m);
};
The above is just crazy but where my mind melts..
