jquery：字符数组，checkbox,find

jQuery：jsp页面获取子节点的值，添加字符串到字符数组，判断checkbox是否被选中

     var origAttr=[]; 
     function getOrigAttr(temp){
        var orig = $(temp);    
        var origStr = [];
        if(orig.length > 0){
            for (var i =0 ; i < orig.length ;i++){
                //将字符串添加到字符数组
                origStr.push(orig.eq(i).val());
            }
        }
        return origStr;
    }


    var temp = $("#Property_c").find('input:checkbox[name=373]:checked');//获取子节点的值：find
    origAttr = getOrigAttr(temp);//调用getOrigAttr函数
    if(origAttr.length>0){
               var checked = $("input:checkbox[name=373]").is(':checked');//判断checkbox是否被选中
            if(checked == true){
                  //遍历checkbox选中的值
                $("#"+id+" input:checkbox[name=373]:checked").each(function(index){
                      str += "\""+$(this).attr("id")+"__"+index+"\":\"";
                      str += $(this).val()+"\",";
                  });
            }else{
                for(var i =0 ; i < origAttr.length ; i++ ){
                    var m= 0;
                    if(origAttr[i] == "IP_adminPort"){
                        m=0;
                    }else if (origAttr[i] == "IP_static"){
                        m=1;
                    }else if (origAttr[i] == "IP_dynamic"){
                        m=2;
                    }else{
                        m=3;
                    }

                  str += "\""+"373__"+m+"\":\"";
                  str += ""+"\",";
                }
            }
        }
