Way to Prevent Duplicate Request from Form in J2EE applications -2

Guys,

Here is the another solution to prevent duplicate form submission issue in web applications irrespective of the framework implementation.

Can you please try with the below code and update me in comments?

In JSP, we can have java script method during onsubmit like below.

And our java script implementation would be like below. submitForm method return true only very first time and form will be submitted. The same will be true for the sub sequent requests. Hope this will solve our issue.

//Global variable
var submitFlag = 1;

//Submit form method
function submitForm(form) {
if ( submitFlag == 1 ) {

submitFlag = 2;
return true;

} else {
return false;

}
}

Thanks,

Way to Prevent Duplicate Request from Form:

Here is the common and widely used mechanism used to preventing duplication form submission from a j2ee application. Ie, disabling the submit button during on click event. Example here is ICICI bank Internet banking application.

Though this is simple and a reasonable approach if we have a single submit button within a form, this may not work if we have more than one submit buttons in a form.

Are you looking for any other simple strategy to prevent duplication form submission from client side? Follow the next blog.
