需要注意的是function里面的function函数的this指针发生改变，用了临时变量var _this= this来保存
var dialog_html= '\
<img alt="点击可以关闭" src="/static/images/disk.png" width="40px" height="30px;">\

</div>';function Dialog(select,store_name) {this.select = select;//原来选择器this.status = ""; //对话框状态this.div = $(this.select); //jquery对象this.store_name = store_name
}Dialog.prototype.get_div = function () {return this.div;
};//弹框
Dialog.prototype.open = function(){this.close();//防止连续创建对话框this.div.append(dialog_html);this.div.find(".loadgif").hide();this.div.css("display",'block');this.div.css("left", window.scrollX+(window.innerWidth - this.div.width()) / 2).css("top", window.scrollY+(window.innerHeight - this.div.height()) / 2);
};//关闭并清理
Dialog.prototype.close= function(){this.div.empty();this.div.css("display",'none');this.status = "";
};//点击取消，鼠标点击和回车键盘都可以用
Dialog.prototype.register_cancel = function (fn) {this.div.on("click keyup",".btnnoOk",function (event) {if(event.type =="keyup" && event.keyCode != 13){return;}fn();});
};//点击确定，鼠标点击和回车键盘都可以用
Dialog.prototype.register_ok = function (fn, status) {var _this = this;//在回调的this会变；this.div.on("click keyup", ".btnok", function (event) {if (event.type == "keyup" && event.keyCode != 13) {return;}if (!_this.check_status(status)) {return;}fn();});
};Dialog.prototype.set_status = function (status) {this.status = status;
};
//检查对话框状态
Dialog.prototype.check_status = function (status) {if(this.status != status){this.close();return false;}else{return true}
};
//保存对话框输入的文本
Dialog.prototype.param_add_input = function (desc, key) {var uuid = sessionStorage.getItem(this.store_name+key) ? sessionStorage.getItem(this.store_name+key):'';this.div.find(".partparam").append('<li><span><no>'+desc+'</no><input type="text" name="'+key+'" width="200px" value="'+uuid+'"></span></li>');
};
Dialog.prototype.param_get_input = function (key) {var uuid = this.div.find("input[name='"+key+"']").val();sessionStorage.setItem(this.store_name+key, uuid);return uuid;
};//请求结果输出
Dialog.prototype.success_output=function (text) {this.div.find(".content span").removeClass("active").text(text);this.div.find(".partparam").css("display", "none");
};
Dialog.prototype.fail_output=function (text) {this.div.find(".content span").addClass("active").text(text);this.div.find(".partparam").css("display","none");
};使用这个类：弹出的时候open一下，然后注册上ok和cancel按钮
