Neat one-click Submit javascript...helps prevent multiple submit clicks

Hi All

I just came across this one. It helps to prevent multiple submits of the same form:

http://www.scriptbreaker.com/examples/disable.asp

The zip file doesn't include the alert, but if you look on the demo page, you can see where to insert an alert. It's good to have the alert so that your users understand that they have to wait for the form to be processed.

Cheers! Smile

That seems to be becoming more popular nowadays, I see paypal use it on almost all of their forms.

Heres another one:

Code:
<HTML> 
<HEAD> 
<SCRIPT LANGUAGE="JavaScript"> 
<!-- 
var submitcount=0;  

function submitOnce (form) {   

  if (submitcount == 0) 
      { 
      submitcount++; 
  return true; 
      } 
   else  
      { 
      alert("This form has already been submitted.  Thanks!"); 
      return false; 
      } 

} 
//--> 
</SCRIPT> 
</HEAD> 

<BODY> 
<FORM METHOD=POST ACTION="some.cgi" onSubmit="return submitOnce(this)"> 
<INPUT TYPE="SUBMIT"  NAME="" VALUE="submit it"> 
</FORM> 
</BODY> 
</HTML>
