$($(" input [name = 'checkbox_name'] [checked] ")).
Each (function () {arrChk + = this. Value + ', '; }); // traverses the collection of selected CheckBox elements to get the Value
$(" # checkbox_id "). Attr (" checked "); // gets the status of a CheckBox (whether checked or not, returns true/false)
$(" # checkbox_id "). Attr (" checked ", true); // set the state of a CheckBox to checked=true
$(" # checkbox_id "). Attr (" checked ", false); // set the state of a CheckBox to unchecked (checked=false)
$(" input [name = 'checkbox_name'] "). The attr
(" checked ", $(" # checkbox_id "). Attr (" checked ")); // according to 3,4,5, you can analyze the meaning of this code
