Solution for multiple ASP. NET submissions

Its principle is: when the Asp.net page is submitted, the validatoronsubmit method (built-in) is called. We use the coverage feature of the js method to replace the built-in validatoronsubmit of the system with our version, then, when validatoronsubmit is executed, all the submit buttons on the page will be blocked (you can also execute your own methods)
// Shield all submission buttons
Function disableothersubmit ()
{
VaR OBJ = event. srcelement;
VaR objs = Document. getelementsbytagname ('input ');
For (VAR I = 0; I <objs. length; I ++)
{
If (objs. type. tolowercase () = 'submit ')
{
Objs. style. Display = 'none ';
}
}
}
// Overwrite the original validatoronsubmit method to prevent two submissions
Function validatoronsubmit (){
If (page_validationactive ){
If (validatorcommonsubmit ()){
Disableothersubmit ();
Return true;
} Else {
Return false;
}
} Else {
Disableothersubmit ();
Return true;
}
}
