Validating to accept both number and char but needing at least 2 digits
Please support our JavaScript / DHTML / AJAX advertiser: PostgreSQL or MySQL? Compare and contrast the two most popular open source databases

I have a field set as number (num) for validation. The code below will only allow numbers to be accepted in the field.
I would like to modify it such that is MUST have at least two numbers and as many characters as the person wants to type.
Can it be done by manipuplating this code?
Thx

firstly, it would be helpful if you pasted the full function. anyways, try to do something like:
1. make sure the length is not less than 2, as you want atleast 2 numbers.
2. do something like:
This way you can further put a condition where say, the length of the input is 5, if the errorCount is more than (length - 2), you print a message.
Hope this helps!!

Not exactlywhat I mean...I think.
Heres the full code. You will easily see what I am trying to do.
In a nutshell, we have to ask form filler outer the names and ages of all in their household. Currently I had to do it in to fiedls but would like to do it in one test area. We would like to prevent garbage being submitted.
The key is force them to have at least one set of digits regprenting at tleast the submitter's age and also their name. It could be that there are 20 people in the family so they might enter toweny names followed by their ages.
Is there a better way to get the data from the submitter that the way I have done it below?

Hope this example will give you some idea on how to validate fields' using regExp()...

Thank you. So this will not error out as long as one types alpha caracters and at least two number?
I'll have to give it a shot. Is this easily integrated into the big code that I showed you or will the entire form need to be rebult?
Thanks

Hi there!
Yes i believe that it can be easily associated with your codes. Try to look at some of my thread here, regarding about form validation.

Hi,
I tried out your code. What input did you use to test it. I tried
Tami 33
and it said I still needed two numeric values.
I'm looking to verify basically as much as possible at least one name and age is entered.
Thx

Based on my declaration with the regExp(), white-spaces are not allowed on this input. The possible combination for this input is Tami22, 22Tami and Ta22mi...
In this case you'll have to change the declaration of the regExp().
If you need some space between characters then you can apply this with the validValue variable.

var validValue = /[\w\s][\d]{2,6}/; you may apply any combination depending on what data you need to gather. Hope this clear things up... Good day to you Would it be asking too much to put in english waht this expression says...
/[\w\s][\d]{2,6}/;
Thanks. Oh, is there documentation that would further explain the options for the above type of expression?
/[\w\s][\d]{2,6}/;

I think I've mostly figured out the code
I've added white spaces to the ends of each option
/([\d]{2,10}[\w][/s])|([\w][\d]{2,10}[/s])|([\w][\d]{2,10}[\w][/s])/;
will the expression pass if there is no white space
for instance if someone enters
Tami33,Rocky34
or will there have to be a white space entered at the end of the above for the expression to pass validation?
