Stop fixed position at certain div or certain position

由 孤街浪徒 提交于 2019-12-13 03:49:51
问题 I need to stop a div which gets a fixed position on scroll before it touches another element, basically make it go back to absolute position at a certain position, and this should be working at any size of the screen. I have a jsfiddle with code and there are two elements, please see the example and help if you know the answer thanks! var navTop = $('#nav').offset().top; var lastMode = "absolute"; $(window).scroll(function(){ var mode; if ($(this).scrollTop() >= navTop) { mode = 'fixed'; }

Excel OFFSET function error when using TREND in reference

由 匆匆过客 提交于 2019-12-13 03:36:04
问题 Consider an Excel sheet with the following values: A B -------- 1| 1 5 2| 2 8 3| 3 11 Entering the array formula =TREND(B1:B3,A1:A3,A1:A3) in cells C1:C3 returns {5;8;11} , as expected. Entering =OFFSET(C1:C3,1,0) returns {8;11;0} , also as expected. However, if I try entering =ROWS(OFFSET(TREND(B1:B3,A1:A3,A1:A3),1,0)) , I get the message, "The formula you typed contains an error". I can't do anything to get it to accept the formula. Next I created the named ranges "TrendRange" and

scrollTop with jQuery offset not working properly in Firefox unless mouseout occurs

由 不羁的心 提交于 2019-12-13 03:10:44
问题 The scrollHash() function below is intended to scroll to a target anchor while adjusting the position to reflect both the fixed menu and desired margin-top . The function works properly in Chrome, however it only works in Firefox if a mouseout event occurs before the function is completed (accounting for the function's duration and setTimeout() ). Otherwise, if the mouse continues hovering over the link in Firefox throughout the function’s execution, the function fails to complete the second

PHP Echo Timezone based on GMT offset

由 筅森魡賤 提交于 2019-12-13 02:14:21
问题 I have an application that stores GMT time data in a MySQL db like this: 2009-12-16 15:27:47. The user's timezone offset is stored in another column like this: -6 The above timezone is GMT-6, which is CST. Is there any way I can echo CST (i.e. - date('T")) from the GMT offset data? Note: I should also add that the application global timezone is set using: date_default_timezone_set('GMT'); 回答1: Unfortunately, there isn't always a single timezone for each GMT offset. Many GMT offsets have

C++ - Is moving char pointer forward by adding integer of bytes legal/recommended?

由 不打扰是莪最后的温柔 提交于 2019-12-12 21:25:08
问题 I am looking for some ways to advance pointers to the beginning of files in compressed archives. I have a character pointer to the beginning of the file that has been read into memory. The archive directory contains the offsets of each file. Is it legal/recommended to say: char* beginning; //Imagine this is assigned to the beginning of the file in memory int file1OffsetBytes = 1000; // Imagine the first file is 1000 bytes into the file char* file1 = beginning + file1OffsetBytes; Is this a bad

你需要知道的RoketMQ

由 白昼怎懂夜的黑 提交于 2019-12-12 17:03:55
1.概述 本篇文章会尽力全面的介绍RocketMQ和Kafka各个关键点的比较，希望大家读完能有所收获。 RocketMQ前身叫做MetaQ, 在MeataQ发布3.0版本的时候改名为RocketMQ，其本质上的设计思路和Kafka类似，但是和Kafka不同的是其使用Java进行开发，由于在国内的Java受众群体远远多于Scala，所以RocketMQ是很多以Java语言为主的公司的首选。同样的RocketMQ和Kafka都是Apache基金会中的顶级项目，他们社区的活跃度都非常高，项目更新迭代也非常快。 2.入门实例 2.1 生产者 public class Producer { public static void main(String[] args) throws MQClientException, InterruptedException { DefaultMQProducer producer = new DefaultMQProducer("ProducerGroupName"); producer.start(); for (int i = 0; i < 128; i++) try { { Message msg = new Message("TopicTest", "TagA", "OrderID188", "Hello world".getBytes

What are possible reasons for not mapping Win32 Portable Executable images at offset 0?

由 谁说胖子不能爱 提交于 2019-12-12 15:11:43
问题 I've been looking into Window's PE format lately and I have noticed that in most examples, people tend to set the ImageBase offset value in the optional header to something unreasonably high like 0x400000 . What could make it unfavorable not to map an image at offset 0x0 ? 回答1: First off, that's not a default of Windows or the PE file format, it is the default for the linker's /BASE option when you use it to link an EXE. The default for a DLL is 0x10000000. Selecting /BASE:0 would be bad
