jQuery对checkbox的操作（转载）

$(document).ready(function(){
    //checkbox全选
    $(\'#btn1\').click(function(){
        $("[name = \'checkbox\']").attr(\'checked\',true);
    });
    //checkbox取消选择
    $(\'#btn2\').click(function(){
        $("[name = \'checkbox\']").attr(\'checked\',false);
    });
    //checkbox反选
    $(\'#btn3\').click(function(){
        $("[name = \'checkbox\']").each(function(){
            if($(this).attr(\'checked\')){
                $(this).removeAttr(\'checked\');
            }else{
                $(this).attr(\'checked\',true);
            }
        });
    });    
    //checkbox选中偶数行
    $(\'#btn4\').click(function(){
        $("[name = \'checkbox\']:even").attr(\'checked\',true);
    });
    //设置table2偶数行背景色
    $("#table2 tr:even").css("background-color","#DBE5F1");    
    //鼠标移上时添加行背景色  css类hover中定义的是背景色，也可定义其他
    $(\'#table2 tbody tr\',this).mouseover(function(){
        $(this).find(\'td\').addClass("hover");
    });
    //鼠标移去时恢复行背景色
    $(\'#table2 tbody tr\',this).mouseout(function(){
        $(this).find(\'td\').removeClass("hover");
    });
    //点击添加按钮跳转页面
    $(\'#btnAddInList\').click(function(){
        var url="/gis/supplyArea/addInListSupplyArea.do";
        //alert(url);
        $.ajax({
            url:url,
            complete:function(){location.href =url}//完成后跳转的页面
        });        
    });
        
    //删除选定的复选框的记录
    $(\'#btnDel\').click(function(){
        var supplyAreaIds = \'\';
        $("[type=\'checkbox\'][name=\'checkbox\']:checked").each(function(){
            supplyAreaIds+= $(this).val()+",";
        });
        //alert(supplyAreaIds);
        var url="/gis/supplyArea/deldeteSupplyArea.do";
        $.ajax({
            type:\'POST\',            
            contentType: "application/x-www-form-urlencoded;charset=utf-8",
            url:url,
            data:{ids:supplyAreaIds},
            dataType:"text",    
            //成功后
            success:function(msg){
                alert(supplyAreaIds+" 删除成功！");    
            },
            //完成后
            complete:function(){
                $("[name = \'checkbox\']").attr(\'checked\',false);//取消选择
                location.reload();//刷新
            } 
        });
    });
});
