I am having few input fields in my jsp page and a submit button. To enter the data in the input fields I am using a barcode scanner and each time I scan the barcode the submit button is getting activated and the form is submitted. How can I prevent the submit button getting activated?

Hi!

I am having the same problem. Have you been able to resolve this?

Thanks for any help.

is there any way to get the values of unchecked boxes .plz no suggestions to keep a hidden value with each check box.if any one knows how the reset button keeps track of the initial value of the checkboxes.can we get that initial value after submitting the form without creating our own array.that is iwant to know can i get the default values from where the reset button gets the default value.it is very clear that reset keeps the information of the status of the checkboxes when the page is loaded.so how can i access the same info after the submmissin of page

It may be because the scanner is *simulating* an enter key stroke.

Instead of making your SUBMIT button <input type="submit">, try making it something like <input type="button" onclick="this.form.submit()" value="Submit"> to prevent the form from submitting when the <ENTER> key is pressed.

Hi,

I am not using RS232 port reader and not the wedge barcode reader device.

Can you please tell how to read the bar code from the port and bringing it to the form using JSP?

thanks,
