I also use JS
// JScript File
// Determine whether to select a record and confirm deletion
Function judgeselect ()
{
VaR result = false;
VaR allinput = Document. getelementsbytagname ("input ");
VaR looptime = allinput. length;
For (I = 0; I <looptime; I ++)
{
If (allinput [I]. Checked)
{
Result = true;
Break;
}
}
If (! Result)
{
Alert ("select the record to be deleted first! ");
Return result;
}
Result = confirm ("are you sure you want to delete the selected record? ");
Return result;
}
But it cannot be deleted,
Is it necessary to write back-end?Code?
Am I writing this?
Thank you!
