Integer Validation before submitting form

[ravindra patil]

HI,
i have form and simple text box that accept integer. the name of text box is not static it will change as request parameter,
now i want integer validation on that field i have added onBlur validation but if i inter any non-integer value its give alert saying its not numeric but doesnt prevent user from submitting form.
how can i restrict user from submiiting form only after entering valid numberic value

as name of text box is not fixed i cannot add onSubmit validation

If you create a css class called say, "only-numbers" then you can add it to the input and then add an onsubmit that looks for all inputs with class "only-numbers" and validates them stopping the submit if the validation fails.

so while validating how will it get field name which is not going to be fixed
e.g
<input type="Text" name="<%=Day%/>
how will you get value of this input as we dont know whch day it is going to be ?">

See the part in the reply where I said

To prevent submission, return false from the submit handler.
