This article mainly introduces jQuery's method of freezing the table header. The example analyzes the implementation skills of jQuery's extension method and the method of fixed table styles, for more information about how to freeze a table header, see the following example. Share it with you for your reference. The details are as follows:
A list needs to be displayed when a project was created some time ago, but the header must be frozen when there i

Design a system (database structure and logical process) to meet the following requirements:
1. the user can correctly obtain the above-mentioned gold coins
2. Users can know at any time how much gold coins they have can be consumed and how much gold coins are frozen.
3. Frozen gold coins can be consumed after th

In Linux, hibernation is mainly divided into three main steps: (1) freeze the user-state process and kernel-state tasks, (2) invoke the suspend callback function of the registered device, and (3) Hibernate the core device in order of registration and put the CPU into hibernation state. The freeze process is the kernel that sets the state of all processes in the process list to stop and saves the context for all processes. When these processes are thawed, they do not know that they have been

single-threaded. For simplicity, putting everything (including GUI events and rendering) in one thread is a good program model, this eliminates the need to consider the complex issues of thread synchronization. On the other hand, he also exposed a serious problem in application development. The single-threaded environment seems to respond quickly to user requests, but when the thread is busy processing other things (such as calling getarticle ()), you cannot respond to users' mouse clicks or ke
Subversion has a standard directory structure.
For example, if the project is proj and the svn address is SVN: // proj/, the standard SVN layout is
SVN: // proj/| +-trunk +-branches +-tagsThis is a standard layout. trunk is the main development directory, branches is the branch Development Directory, and tags is the tag archive directory (cannot be modified ). However, SVN does not have a clear specification on how to use these directories, but it is still a habit of users.
