I'm trying to match all integers before and after the hyphen:
12345-5
This is what I tried but always returns null
Code:
var divID = '12345-5';
var idPattern = /^[0-9]+$/; //Matching one or more numbers before the hyphen
var id2Pattern = /^-[0-9]+$/; //Matching starts from the hyphen and all numbers that proceed

I am sending credit card information to a merchant account script. The documentation for the MA states the variable names it requires, things like card-type, card-number, card-exp. So I have input fields for each.
The problem is my JS validation function will not recognize these variables if they have a hyphen. If I change the hyphen to underscore, the function will recognize them, ex:
<input type="text" name="card-number">
<input type="text" name="card_number">
alert(document.frm.card-number.value);//NaN
alert(document.frm.card_number.value);//works
I can not change the field names to use underscores because the payment script is looking for the hyphen variable name. Anyone know how I can get the values of these fields with hyphens?
I am trying to pass dynamic String parameter to my javascript. The user enters sdome value and that is passed to the javascript as parameter. My problem is when user enters something of type cs204-1 or cs204.1 etc, the javascript does not run. On passsing simple parameters like cs204 or 111 etc, the javascript works fine. I need to pass any type of parameters to the javascript ( cs204-1 or cs204.1 etc) as I am making this for my college and the values to be entered by the user are of such type. My javascript code is : Code:

I tested the working of the javascript by using alert. It came for normal parameters but not for cs204-1 or cs204.1 types.
I am currently working with a cms system that doesnt keep within the correct name conventions (pre defined).Within a form, I simply want to set a date to todays date:
<script type="text/javascript">
function initdt(mf) {
var t = new Date;
[code]...
This works perfect on a form I create, but sadly I must use a form within a pre defined system that uses "01-date" Is there a way around this? A simple way of setting 01-date to t.getDate();

I have written a function for accepting name and should be atleast minimum 4 characters. It is accepting all characters including special characters. Now i want my function to accept only a-z0-9 and _(underscore),-(hyphen) and .(dot) Below is my function

This is the regular expression I currently have
/^(w+|w+.w+)@(w+|w+-w+).(w{2,3}|w{2,3}.w{2,3})$/;
The script dates from about 2006. The script is ok for emails that just contain a "dot" before the @, as in: joe.bloggs@home.com
What needs to be changed in the above script to allow both these types of email?

I need US zip code formatting on my page. As zip code can be 5 digits or 5-4 digits, our requirement is that when user types in 6th digit, hyphen automatically gets added between 5th and 6th digit. Ex: user enters 100161, it should become formatted as 10016-1 and then user can continue to add rest of digits.

I am implementing several scriptaculous sliders in my app... and one thing I can see being an issue is setting their "values" property to limit the selectable values.
This property takes an array of integers representing the allowable values. Unfortunately without this property, the slider will allow you to select a decimal value, so I can't just use a min and max if I only want integer values output.
Creating an array for a small data set is simple: for example "values: [0, 1, 2, 3, 4, 5]"
But some of my sliders will range into the hundreds and need an array of hundreds of allowable values. Is there a simple way to generate an array of 0 to 100 integer values (or more). I know I could use a for loop but it seems to me there might be an even easier way, though I cannot find it.
I would like it to fit in a code block like this:
javascript Code:
var s1 = new Control.Slider('handle1',
'track1',
{
axis:'horizontal',
[Code]....
EDIT: for further clarification, I found that PHP has a range() function that does exactly what I want. Anything comparable in Javascript? [URL]
I have an array holding 100 randomly generated integers between 0-9 inclusive...firstArray[99]
how do i use a second array to keep count of how many times each integer is generated..secondArray[9]
im just doing a little test and this might seem like a really stupid question but i cant figure it out...all i simply want to do is take all those numbers and get the sum then display the sum in a document.write in theory i should get 10 but i dont and idk why i have tried many many things
var numbers = new Array();
numbers[0] = 1;
numbers[1] = 2;
numbers[2] = 3;
numbers[3] = 4;

1.000.000,00 // throw error

And on success I have to get all numbers before the dot or comma .
I'm a newbie to javascript and I made this script
<script>
var num = parseInt(prompt("Enter the number of integers to follow"));
var sum = 0;
for (i = 0; i < num; i++){
sum += parseInt(prompt("Enter a number"));
}
if (isNaN(num)) {
alert("Invalid");
} else {
if (sum < 0) {
document.writeln("The sum is 0 and the average is 0");
} else {
document.writeln("The sum is " + sum + " and the average is " + sum/num);
}
}
</script>
The scenario : Create in javascript that will read a series of integers at the terminal. The first integer is special, as it indicates how many more integers will follow. Your javascript is to calculate the sum and average of the integers, excluding the first integer, and display these values to the screen. If the total is not greater than 0 then display "The sum is 0 and the average is 0". Did I write the script correctly? am I missing anything that a dumb person might do? for example the person might type in letters instead of numbers.

I'm trying to create a script where all the hyperlinks in a page will be replaced with a new set of coding before it. (e.g: a href="this.htm?http://www.google.com").
My code generates this change through a series of random numbers and only runs the script when "2" is the generated number (out of 12). Now, I only know how to replace all occurrences of "href" in all "a" tags, but there are times when I use Javascript to launch new windows or even javascript to navigate to the top of a page.

View 3 Replies View RelatedI can remember seeing a function some time ago, but I cannot recall
what it was or how to use it.
I am wanting to have two arrays - oldArray & newArray.
I need a function which I can call so that it will look inside the
specified string ("theString") and replace each instance of each entry
of oldArray with the corresponding entry in new Array.
Example:
theString = "12345678";
oldArray = new Array("1","2","3");
newArray = new Array("One","Two","Three");
theString = theString.XXX(oldArray,newArray);
// theString = "OneTwoThree45678";
Any ideas, suggestions, references?
I have been working on this for a few hours and am frustrated
beyond all extent. I have tried to research this on the web as well
with no success. I am trying to match certain contents within a
wrapper div. So for example if the inside of the wrapper div was the
following:
<div id="wrapper">
<a href="#">a great link that contain text and symbols</a>
<div... </div>
<div... </div>
</div>
I would like to strip out all the internal div's. But because there
can be alot of internal div's, I figured it would be less processor
intensive to just match the first 'a' tag and repopulate the wrapper
div with the match. I am trying to use something like the following
regex:
re = /^<a(.+)</a>/;
with the following statment:
$temp = document.getElementById('wrapper').innerHTML.match (re);
but this is returning the entire contents of the wrapper div. I have
tried variations of the regex and either continue to get the entire
contents or null returns. Any help would greatly be appreciated.
BTW, I can't match to the first because the contents may be touching (ie ...</a><div>...).
