在grid结果集中实现全选或全不选某些特定的行

function check(){
    var id = gridgetselectvalue("require_id");
    if(id.length<1)
        return;
    //var arr=id.split(";");
    setcheckstatebyid(grid,id);
}
function setcheckstatebyid(grid, id) {
    var main = grid.gettable("11");
    var table=document.getElementById("grid");
    var rows = gridreport_Rows(main);
    var num = rows.length;
    var frow;
    var fselect;
    var i;
    if (num > 0 && gridreport_getcheckvalue(rows.eq(0)) != null) {
        var ischecked=table.rows[rowindex].cells[0].childNodes[0].checked;
        //alert(ischecked);alert(id);
        for (i = num - 1; i >= 0; i--) {
            frow = rows.eq(i);
            fselect = frow.children().eq(0).children().eq(0);
            if(table.rows[i].cells[1].innerHTML==id){
                fselect[0].checked = ischecked;
            }
        }
    }
}
var rowindex=0;
$(document).ready(function(){
    $("#grid td").bind("click",function(){
        //colindex = $(this).index();
        rowindex=$(this).parent().index();//表示所在行的索引。如果要的是列的索引，把parent()去掉
    });
});
