Turn list with parent ID to tree, ID list to tree
We know that databases generally store trees in a list (id,pid). How to extract the tree? The simplest method is to check the table according to the PID loop. But there is no doubt that this creates a huge database query overhead.
Then the general recommended method is to isolate all relevant data at once, but th
The package set selected with jquery returns a JQuery object, and the DOM object is returned with document.getElementById.jquery objects---dom objects/* Convert a JQuery object to a DOM object.*/var jquery = $ (' #id ');Alert (jquery.html ()); var dom = jquery[0];or var dom = jquery.get (0);alert (dom.innerhtml);Dom Objects and jquery objects/* Convert a DOM object to a JQuery object.*/var dom = document.getElementById ('
In Linux, each process has two IDs: User ID and valid user ID. uid generally indicates the process creator (which user is created ), EUID indicates the process's access permissions to files and resources (which user has the same permissions ). You can use the getuid () and geteuid () functions or two ID values of the process. When a user logs on to the system, th

To facilitate future classification search and query and ensure the uniqueness of the company (including its subsidiaries), I want to add a column in the above two tables. The column name is guid.

[Regular expression] ask how to "match the end or end of a string." For example, mvid=17328895840scm=102 and mvid=17328895840 can all match
Example:
str = mvid=17328895840scm=102
Reg = "/id= (./) /u";
This should be able to fetch 17328895840.
But mvid=17328895840, this is not going to match.
I tried the next reg = "/id= (./) [|$]/u";
Ask how to write a regular to match both of these situations

Components in Android need to be represented by a value of type int, which is the value of the id attribute in the component tag. The id attribute can only accept values of the resource type, which is the value that must begin with @, for example, @id/abc, @+id/xyz, and so on.Using "+" after @ means that when a layout
In the development process, we usually use auto-increment numbers as the id primary key for data tables, and id is a numeric type, which is not easy to understand. After converting IDs into numbers in a certain format, it is easy to know what the IDs represent.
