Implement full checkbox Selection in asp.net

In asp.net, the server control automatically generates the ID and name attributes. Therefore, it is more difficult to use javascrip to achieve full selection.
By searching for information, I think it is relatively simple to use javascrip + jquery in combination to implement it from a simple perspective.
The following code is used:
[Javascript]
Function quanxuan (){
Var obj = document. getElementById ("btnSelectAll ");
If (obj. value = "select all "){
$ ("Input: checkbox"). attr ("checked", true); // set all to selected
Obj. value = "cancel"
 
}
Else {
$ ("Input: checkbox"). attr ("checked", false); // set all to unselected
Obj. value = "select all"
}
 
}

Call code:
[Html] www.2cto.com
<Input type = "button" id = "btnSelectAll" value = "select all" class = "input_btn_search" onclick = "quanxuan ()"/>

Of course, my practice is rough. I have selected all the checkpoints in the document. If you want to select a specific checkbox, such as a check box in a table, you can use the jquery selector to filter. For example:
[Html]
$ ("Table: checkbox ")
