JQuery :: Validate A Text Input To Not Accept Numbers
Aug 7, 2009
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:
provide the HTML/Javascript to ensure a field can only accept numbers? (I don't mean post-submit validation, but literally the field only accepts numerical input.)
I have the Validation plugin working fine other than the accept method. I can't seem to get it to fire. I have looked at the demos on the site but still can't get it to work. All the other fields with the class of 'required' get caught (when blank) and even the file gets caught (when blank) too, just not the file type.
I have been presented with: Draw a flowchart and write a javascript program which will accept two numbers from a user and will determine whether the second number is a factor of the first. This is determined by dividing the first number by the second and checking if the remainder is 0. This is made easier if you find out what the operator does. The output should be in the form 4 is not a factor of 6 and 3 is a factor of 6. I have tried a few attemps and yet still not sure what the problem is :confused:
I'm trying to validate the text of an input as it is typed.I have this keyup:[code]The idea is that only let the user type a decimal number; and it does.The only problem is that it let type a dot [decimal separator I need] at the beginning; and I don't want that.I've been a while and searched Google for the Reg Exp, but had no luck.
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.
using jQuery, how to validate a required input text before submitting or placing the cursor in another field? I've tried this below but it doesn't work.
I have an input text with value=Lois so I want to validate this input. If some user enter another word different of Lois will give an alert, and if in the field one writes the word Lois (without importing capital letters or minuscule) the form can be executed in correct form.
I'm trying to implement a OSC addon to update the options price in realtime fromww.oscommerce.com/community/contributions,1385, but it seems to only work with single characters currency symbols, like $, €, £, etc. any symbol that as more than one character, like Brazil Real R$, or C€, or Svenska Kronor Skr, doesn't work and the price doesn't update, it stays R$ 0.00 whatever options you choose.I need to use this contribution with the Brazil Real symbol at the left of price like R$ 999.00.Also I can't make it work like 10.000,00. It only works like 10,000.00. But this point is not so important.I have tried everything for some days, but I don't know javascript.Here is the code:
I need to validate three textboxes and it will validate for numbers. How should I change my code to validate three textboxes?

I need to use Javascript to validate 3 textboxes, whereby the users can only key in numbers (because they are phone numbers related fields). If any of the textbox is empty, display an alert message to show which textbox is empty. I do not want to show many alert messages to show that, for example, text1 and text2 are empty, it will show two alert messages. I would need to show one "summarized" alert message instead.
have 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.
that a javascript which is validating a phone number accepts only digits but if the text field is left empty it should accept the entry as an empty entry...
I'm trying to make sure that when a user enters information into my textbox, that when the textbox loses focus then it checks to make sure that they entered numbers and not text or other characters. Numbers only....Any suggestions?
I am unable to solve two problems creating a contacts form using dreamweaver CS3. My other problem is posted under the heading, "Modify code created with Dreamweaver CS3, to compare two text feilds". For this posting, can someone please tell me how to modify my code, pasted below, so that the "First Name" and "Last Name" text fields are restricted to accepting only alphabetical characters.
Here's my current code

i'm fairly new to regular expression and want to know if it's possible to check a text field value. I need to only accept value between 0 and 20. I've got also a problem with the 0 value ... guess the script think it's false :
if(!Number(document.data.f_cat_1.value) || document.data.f_cat_1.value > 20){ alert('Your must enter a numeric value between 0 & 20 pts!'); document.data.f_cat_1.focus(); return false; }
I have this java script code in my php file wherein I used this as my validator..for the inputs in different fields in my textbox. How to create a validation that only accepts letters... in my first name and last name field. I also wanted to know how about accepting numbers only in my field.
Here's the code: <script type='text/javascript'> validation and submit handling $(document).ready(function(){ $('#employee_form').validate({ submitHandler:function(form){ $(form).ajaxSubmit({ success:function(response){ tb_remove(); post_person_form_submit(response); }, dataType:'json' }); .....
This is an assignment I have for a course I am taking. The objective is to validate the zipcode of a form to ensure that it only contains numbers. I cannot get this to work. The teacher wants us to use the for loop to do this, otherwise I would use a different function. Code: <!DOCTYPE html> <html lang="en"> <meta charset="utf-8"> <head> .....
