I need a validation script .
I have a textfield for amount.
I want user can not type more than 100 in this textfield…also user are not allowed to type more than two decimal.
so user can type from 0 to 99.99
Could you please suggest a solution.
I am looking for a concise easy javascript or jquery solution which could help…
A regular expression (regex) would be your best bet.
This pattern should work for you (disclaimer, I found it elsewhere):
^(?=.*[1-9])\d{0,2}(?:\.\d{0,2})?$
You can do this purely in HTML if you wish - take a look at this page and see how you go on.
The decimal places might be a little harder, but take a look at this also
I’m not using HTML 5
What are you using instead?
I found a script in web which seems working as per my need.
Is it possible to modify this code so that user can not type more than 100 ?
I am not sure where to put that restriction in the code…i.e user can type max = 100
so , 0… 99.99 , 100 // all these are valid values.
Solved myself. No problem.
Almost everyone is using browsers that support HTML 5 now. If you are not using it then you will be one of the minority where you are relying on the server side validation. For most people whose browser is using HTML 5 the pattern attribute will pick it up before sending it. More people’s browsers support HTML 5 than have JavaScript turned on so a JavaScript solution instead of an HTML one will just mean more people don’t get it validated in their browser.
