1. Check whether the Touch ID is available.
2. Obtain the fingerprint verific

The $ (ID) is a shorthand for the JS document.getElementById (ID), which is defined as a way to directly use $ ("Img-icon") similar to jquery in a later call. onclick simple encapsulation. So many people like to write this:

In many cases, we will set a field in the database table: ID, which is an identity, that is, a self-increment ID. When the concurrency is large and the field is not a primary key, it is possible to repeat the value, or in some cases (such as when inserting data, or when a user deletes a record using delete), the ID value is not sequential, for example, 1, 2,3,5,6
Some time last year, I began to explore improvements to ASP. net4.0 web forms. I found some exciting improvements in ASP. net4.0, and I confirm that all of these will make web development easier and provide us with more flexibility. So I picked out these exciting ASP. net4.0 features one by one. Earlier, I wrote

A few days ago, I studied database sharding and database sharding. One of the key issues is the generation of a unique key. If the data table contains 0.1 billion data records, it is constantly increasing, here we need to consider the sub-table and sub-database. Assume that we use hash or the user modulo operation to split the table into 10 tables, with the same structure for each table, there is a primary key ID, so the IDs in the 10 tables must be u
