that a simple question, I hope. I have an input (<input type="text" />) on my page, and I want it to only accept numbers, so if the user types anything that's not a number, it will be removed instantly. A simplified example just to illustrate:
<body>
<input type="text" name="numbers" /> <!-- I want this input to accept
only numbers -->
</body>
I have searched the internet and couldn't find a problem regarding this issue. The thing I want to do is simply validate a text input so when you enter a number in it, it won't validate and give you an error message. This is the code:

I am not new to jQuery but I just want to ask the best way to approach this. Basically I have a textfield in which the user is going to type in a number (for example 20) and after this textfield lose focus jQuery will be triggered to create whatever number of textfields the user put before (in this case 20).
So, to illustrate: How many users do you have: [ 2 ](and after the field above lose focus, the below will be generated)
Fullname: [ ]
Fullname: [ ]
I am trying to add these 2 numbers as the form input. When I add 5 and 5 it returns 55 instead of 10.
Code:
var a = document.f.children.value;
var b = document.f.totalguest.value;
var c = a+b;
This is my program:
And my question is how to make it display error if I have entered letters in the age box or numbers in a name box? Currently I have only if it is different from 1, so what should I write instead of 1 ?
I'm creating a page that calculates a number depending on what value is inputted into a text field. I need to create some javascript that updates this new calculated value and outputs it next to the input field. Anytime the user changes the number, it recalculates the value. My calculation is currently being produced by PHP, however if I need to, I can create javascript as well to recalculate these numbers.

I made all numbers double digit just for show in the example so the table is easier to read. So far the code I have is just trying to create the array and fill with numbers from the user. This asks for a number once then doesn't display anything at all.

I need to modify the script showed at: [URL]
Right now it allows entering "numbers only", I need it so that it allows numbers and alphabets only, no special characters or spaces.
And yes, one more question, does the first part of the code need to be added in the <head> of the document or <body> ?

I am working on a Phone Number Form. The link of script: [url]
Questions:
(1)I wanted to know if code this script so that instead of the phone number appearing as: (123)456-7890
So that it appears as: (123) 456-7890 with a blank space after the ")"
(2)If that's simple, is there a way to error-check it so that only numbers can be entered into the phone number input field?

I thought this would be fairly easy, but I've searched and searched and came up with nothing that works. I just need to add row numbers to my table. I already have the first column blank, I just need the row numbers stuck in there. I've found examples using .index() and .rowindex, but I can't find anything that works right.

View 2 Replies View RelatedI have pagination enabled in my site using jquery. here is the pager code i am using to display my page numbers, next and previous buttons etc. Everything works except that when I click on a product to view the product details and hit a back button i have in that page to come back where one came from, it always takes back me to the first page.
What i mean is if i view a product from page 2 instead of taking back to page 2 it always takes back to page 1.
I am wondering if in passing the current page number to my back button, so it remembers the page where it came.
click on any image and hit the back button, it always goes back to page 1.

View 2 Replies View RelatedCurrently I'm trying to create a menu with a mouseover effect on a link, which causes an image to display. All images are positioned on the same place, so the optical effect is that one image changes all the time. To achieve this I created an unordered list with the links / items in it, and I created a div with the (corresponding) images. On a mouseover event over a link, the index number of the current li element is stored in a variable, and I want to use that variable to select the corresponding image.
(So <li> index:2 corresponds to <img> index:2)
So in 'human language':
on mouseover of li {
var indexNumber = li.indexnumber
change class of img[indexNumber]
}
But I can't get it to work. I managed to store the 'current' indexnumber successfully in a variable:
var indexNumber = $("li").index(this);
But I can't use the variable to select the corresponding <img> I tried:
$('.slidemenuImgbox img:eq(indexNumber)').addClass('slidemenu_show');
But nothing happens
However when I do:
$('.slidemenuImgbox img:eq(1)').addClass('slidemenu_show');
The image with index:1 is changed.

View 3 Replies View Relatedhave a form with three fields for home phone, work phone & mobile phone.I've got jquery to validate that the numbers entered are the right format, i.e. using the following with custom methods for the phoneUK etc.The thing is I only need one of these numbers. I have been trying *all day* to try and get this to work but no joy. I know I need to group them somehow but can't figure it out.I want it so I get a single message if all fields are left empty and then if a field does have an entry then it's validated to ensure its a number.
View 1 Replies View RelatedAs recently as 1.4.3 $('input:text') would find input elements with no type attribute, but after upgrading to 1.5.1 that is no longer the case.
Is this a bug or an intended refactor to be more standards compliant?

I am having a form with two input fields. I want to enter some text in the first input field and then the second field should get the same text. Is there a simple way (maybe a plugin) to do this with jQuery? It would be perfect if I even could output all these input fields values as normal text in <p> or <li> tags.

I'm using Tablesorter since few months and it was working very well.I did a small change yesterday in my php code: numbers over 1000 are nowformatted like this: 1 000, 1 000 000 instead of 1000 or 1000000.Since I did this change Tablesorter seems to have problems sorting this kindof formatted numbers with spaces. It just doesn't sort the way it should
