Explain the strange performance of maxlength attributes in textarea, maxlengthtextarea
HTML5 has brought a lot of changes to the form. For example, the maxlength to be introduced today can be used to limit the maximum number of characters entered in the input box, more conveniently, the pasted content can be automatically truncated based on the number of characters.
Recently, this requirement was met. Users can enter up to 600 characters (Chinese char

Slideup () method and Slidedown () method
1, the Slideup () method and the Slidedown () method only change the height of the element. If the display property value of an element is "none", the element will extend from top to bottom when the Slidedown () method is invoked, and the Slideup () method is the opposite

According to Microsoft's past philosophy, the installation of the operating system while IIS also automatically started, for many Web applications to provide services, Windows 2003 is a major breakthrough in the practice. In Windows 2003, there are three ways to install IIS: Use the Manage Your Server Wizard to use the Add/Remove Windows Components feature of the Add or Remove Programs in Control Panel, or perform an unattended installation.

NFS serviceNetwork file systems constitute the basis for sharing files in the Unix world. If you want to disable any shared directories, you can add NFS restrictions, such as locking the/etc/exports file and defining the shared directories in advance. If you do not want to share the file with users and only restrict user access, you need to modify the NFS startup script. Edit the/etc/init. d/nfs file, find a line of the daemon and comment it out.

When cach_to_apc is used, the cell is saved in APC and only the index is saved in memory. By default, the APC cache timeout time is 600 seconds, which is sufficient for most applications. You can also m
