how do i count the number of elements in a form ?
document.FormName.elements.length
i get this error from mozilla firebird:
Error: document.FormName has no properties
are u allowed to access forms directly in this way ?
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..
I'm trying to figure out how to make something happen only if there are more than one link inside a div.[code]For now I'm trying to make the little div with the class "cover caption" NOT move when there is only one link in the div.THe reason for this is that I want the whole div to be clickable if there is only one link inside.
View 1 Replies View RelatedI have a form element that looks like this:
<input type="text" onchange=doSomething(this)>
and a function:
function doSomething(theField){
}
I know that within the function I can access properties of the field (e.g. theField.name and theField.value). But how do I access theField's index number in the form's elements[] array -- from the "this" reference that was passed to the function? I.E. if this field is elements[3], how can I get at that 3?
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).

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

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 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 9 Replies View RelatedI'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)
