I am using onblur() event in an ASP page to validate the data entered in a textbox. Data should not be aphanumeric. It should be only numeric. The code is working fine:

<td><input type="text" id=txtPSTelExtn name=txtPSTelExtn size = 4 maxlength = 4 onBlur="validateEntry(window.document.frmOfficer.t xtPSTelExtn)" value =<%=PSTelExtn%> ></td>

But i want to know if there is any alternative to using onblur event. I dont want to use it. I guess it gives problems sometimes.

Thanks

You will probably get more answers in the HTML Code Clinic or JavaScript How-To forums, as this has almost nothing to do with ASP. You are only giving the textbox a value with ASP.

Besides, what kind of problems do you experience using onBlur?

Hello,

Your other option is to validate it when the form is submitted. You can use javascript at the form level to validate elements when the form is being submitted. Other than that, I know javascript has onblur and onfocus events for retrieve/lost focus.

I dont think there is an alternate to this.

1) You can use write a Javascript function and validate it at client-side once the value is entered and focus is off from this conrol otherwise onclick of SUBMIT button validate all the FORM controls using an user-defined javascript function and return sussess/failure on validation and submit the form based on the reult returned.

2) You can submit the values from the form and validate it using ASP functions at the server-side.

AFAIK, there is no other possibility.

I would STRONGLY suggest doing both client-side and server-side validation as a good practice, as considering the cross-browser-compatibility, some functionalities may work in some browser and some may not. But you got to take pain in coding for both the types of validation for the better working of you app.

Hope that Helps.
Cheers!
