Before their own forum because the program source code with the WIN2000 registry conflict, Post issued will appear invalid page, so that the forum has a lot of malicious repeated posts, and then came up with a way to avoid duplication with JS submission, the following is part of the source code:
<script language= ' JavaScript ' >
function Formsubmit () {
Today = new Date ();
var nowhour = today.gethours ();
var nowminute = Today.getminutes ();
var nowsecond = Today.getseconds ();
var mysec = (nowhour*3600) + (nowminute*60) +nowsecond;
if ((mysec-document.formsubmitf.mypretime.value) >600)
600 is only a time value, that is, 5 minutes to prohibit repeated submissions, the value of your happy set
{
Document.formsubmitf.mypretime.value=mysec;
}
Else
{
Alert (' Press once is enough, do not repeat! Please wait patiently! Thank you for your cooperation! ');
return false;
}
Document.forms.formsubmitf.submit ();
}
</script>
</HEAD>

<input type=hidden name= ' mypretime ' value= ' 0 ' >//This sentence cannot be reduced by passing an initial time value with an implied variable
