validate on blur ?

Kevin Spencer · Jun 28, 2004

There is indeed an "onblur" event for an input type="text" form field. What
exactly do you want to know?

For client side validation, this would be easy. To mix into the current .NET
framework validation is trickier (most likely subclass the validator with
custom script). There are events to put out JavaScript, but it is not as
easy as just dropping a control and setting properties.

There are support articles on setting focus, which can be used to work your
validation:

Hi,

i have input type=text and i want to make validation on the onblur (lost
focus) event.

i need to call some javascript function for validation with the control id .

is there something like that possible / documented?

TIA, z.

If you want to execute javascript on the client, add this to your page_load:

'With <name of text box here>

'.Attributes.Add("onBlue", "<JavaScript Function Name ()>")

'End With

Within the <head> tag of your .aspx page, create your fuction to execute for
the onBlur event.
Thanks,

PS for Server side validation, I would use a Custom Validation control to
call a page behind sub or function.

sorry i'll make myself more clear:

i'm using a dot net validator, the validator validates the input upon
submit.
i want to call some javascript method, so the validator make validation when
i call it.
is this possible?

That I don't know. ASP.Net validator classes are designed to work a certain
way. I do my own custom validation, so I'm not as familiar with them as I
ought to be. However, I am reasonably sure that if an ASP.Net validator
Control doesn't do what you want, you could certainly write one that does.
