The jquery method is as follows:
Copy codeThe Code is as follows:
Function CheckAll (val ){
$ ("Input [name = 'chkjob']"). each (function (){
This. checked = val;
});
$ ("# ChkAll"). attr ("checked", val); // you can specify the status of the Select All button.
}

Val this parameter specifies the selection status of the all-selected button.
Name = 'chkjob' is the checkbox name in the list.
ChkAll is the name of the all-selected button.
I like Jquery's simplicity and clarity ···
It is a little different from JavaScript writing!
Eg:
Select All javascript code
Copy codeThe Code is as follows:
// Select all
Function checkall (){
Var all = document. getElementsByTagName ("input ");
For (var I = 0; I <all. length; I ++ ){
If (all [I]. type = "checkbox "){
All [I]. checked = true;
}
}
}
// Invert Selection
Function checknull (){
Var all = document. getElementsByTagName ("input ");
For (var I = 0; I <all. length; I ++ ){
If (all [I]. type = "checkbox "){
All [I]. checked = false;
}
}
}
