To validate its input, I need to know how many text boxes are in the form.

I'm currently trying something like:

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

Count The Number Of Characters

Feb 24, 2009

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.

JQuery :: Count To Specific Number

Dec 17, 2010

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).

JQuery :: Count Number Of Clicks

Nov 12, 2010

I'm creating a small contextMenu for my website:

// Right click on file
$('.file').live('mousedown', function(event) {
// If rightmouseclick (=3)
if(event.which == 3) {
$(this).bind("contextmenu", function(e) {
e.preventDefault();
});
[Code]...

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.

Count The Number Of Words In A Textbox?

Apr 13, 2010

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?

Count Number Of Times A Code Is Run

Aug 4, 2010

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.

Count The Number Of Elements Who Display Block?

Sep 26, 2009

So 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..

How Can I Count The Total Number Of Results Displayed?

Dec 2, 2002

I'm currently working on a javascript form validator and have run into a problem. The validator is used to make sure that the customer has entered a number in the quantity input box of the item they wish to purchase.

Code:

function validateRE(fieldToCheck, strRegExp, msg, min, max) {
if (!min) { min = 0 }
if (!max) { max = 100 }

for (i=0;i<15;i++)
{
if (fieldToCheck[i].value) {
var re_pattern = strRegExp;
if (!re_pattern.test(fieldToCheck[i].value) || fieldToCheck[i].value.length < min || fieldToCheck[i].value.length > max) {
alert(msg);
fieldToCheck[i].focus();
fieldToCheck[i].select();
return false;
}
}
}
return true;
}
Used with:

Code:
<form method="post" action="../some_URL"
onsubmit="return (

validateRE(this.quantity, /^[1-9]{1}$|^[0-9]{2,3}$/,
'Please enter a Quantity.', 1, 3)

);">
The part in question is the red highlighted section.
The number of items that is under a specific product is generated dynamically and can range from 2-20. How can I get javascript to count the total number of items and run "for i=0;i<total number" instead so it is different for each product page?

I am trying to create an image gallery, with two buttons next and previous which work fine, and with a counter like (1/10) etc. I've got it to work but for some reason the slideshow never counts the first image so therefore is always one image behind. Somebody pointed out to me it is probably that the array starts at 0 and something else at 1
