$( function () {    // 全选    $( "#btnCheckAll" ).bind( "click" , function () {      $( "[name = chkItem]:checkbox" ).attr( "checked" , true );    });    // 全不选    $( "#btnCheckNone" ).bind( "click" , function () {      $( "[name = chkItem]:checkbox" ).attr( "checked" , false );    });    // 反选    $( "#btnCheckReverse" ).bind( "click" , function () {      $( "[name = chkItem]:checkbox" ).each( function () {        $( this ).attr( "checked" , !$( this ).attr( "checked" ));      });    });    // 全不选    $( "#btnSubmit" ).bind( "click" , function () {      var result = new Array();      $( "[name = chkItem]:checkbox" ).each( function () {        if ($( this ).is( ":checked" )) {          result.push($( this ).attr( "value" ));        }      });      alert(result.join( "," ));    }); });

Problem Description: The first point to select All can, and then click on the whole selection, then click on the Select all, all do not select, the reverse selection will not react, and later with other browsers to send can, so the feeling is compatibility problem, later access to the data found that is true, reference address http://jquery.com/
