多选框--设置选中项的触发事件

$("#field11320").change(function(){
    if($("#field11320").prop("checked")){
         // console.log("you");
              $("#field11341").attr("readOnly","true").css("background-color",'#EEEEEE');
              $("#field11825").attr("readOnly","true").css("background-color",'#EEEEEE');
              $("#field11826").attr("readOnly","true").css("background-color",'#EEEEEE');
              $("#field11342").attr("readOnly","true").css("background-color",'#EEEEEE');
              $("#field11343").attr("readOnly","true").css("background-color",'#EEEEEE');
    }else{
            //console.log("wu");
              $("#field11341").attr("readOnly","false").css("background-color",'white');
              $("#field11825").attr("readOnly","false").css("background-color",'white');
              $("#field11826").attr("readOnly","false").css("background-color",'white');
              $("#field11342").attr("readOnly","false").css("background-color",'white');
              $("#field11343").attr("readOnly","false").css("background-color",'white');
        }
});

1.设置一个触发事件，然后检验多选框是否选中，选中就修改代码样式即可
