Preventing form submission twice by doublclicking the submit button 1

[cshncn]

Hi,

Just wondering if ColdFusion has anything to prevent form submission twice when user doubleclicks the submit button. I know Javascript can do the work. But I want to know if there is any server sider solution for this. Thanks.

Hi cshncn,

I usually have a session marker variable set. When the user hits Submit, the action template checks for the existence of the variable, and then whacks the variable. Subsequent calls to the action template won't find the session variable, so the database action doesn't take place, and the user is redirected to a "Sorry, you already did this" page.

HTH,

Thank Phil. I tried the session variable control. It works for click twice with an interval, but when I doubleclick, the action page is still executed twice. I guess the session control on the server is not fast enough to capture the doubleclick and stop the second form submission?

lets see your form/ javascript and submit code...

Maybe it's also possible to set a session variable if the user clicks the send button.

If he sends it twice in a difined timspan, you can give the user a error message....

Good Luck, Mike

I think you better stick to the JS solution. You don't have to complicate things

javascript is the best for this. you want to be able to prevent the form from being submitted twice from the CLIENT side of things.

in your submit button add

onclick="this.disabled=true;"
