DomThe Document Object model, or DOM, is the standard programming interface recommended by the Organization for the processing of extensible flag languages . The Document Object model dates back to the late 1990 's "browser Wars" between Microsoft and Netscape, which gave the browser powerful features in order to make life and death in JavaScript and JScript. Microsoft has added a number of proprietary things to Web technology, including VBScript, ActiveX, and Microsoft's own DHTML format, makin

The preceding administrative divisions are divided into three levels by code: province (the last four digits are 0)/City (the last two digits are 0)/County, and their levels are marked separately, in this way, it is easy to query based on different levels later.
First, expand a new sjbm line based on the preceding table, which indicates the upper-level administrative area to which the administrative area belongs. The Code is a

Today, I encountered a feature that I always wanted to do but I didn't have the opportunity to do. Now I will record it when I finish it today.
What is the specific function this time? In fact, it is quite simple, that is, when users register, they can choose the province, city, and county, a very simple small function.

index a heap. If you create a table in an Azure database, there is no choice; Each table must be a clustered index.ConclusionA clustered index is a sort table that is specified by you when the index is created and maintained by SQL Server. Any row in the table can quickly access its key value. Any set of rows in the index key sequence can also be accessed quickly within the scope of the key.There can be only one clustered index per table. The decision about which columns should be clustered ind
So far, the solutions we've discussed are not standards. Although XMLHttpRequest is widely supported, you've seen that the process of creating XMLHttpRequest objects differs depending on the browser. Many people mistakenly believe that Ajax is supported by the consortium, but not in practice. The consortium solves this and other drawbacks in a new standard whose name is fairly long: DOM Level 3 Loads and sa

and the English version of the pair:As we ' ve seen, a pointer is an object and can point to a different object. As a result,We can talk independently on whether a pointer is const and whether the objectsTo which it can point is const. We use the term top-level const to indicate thePointer itself is a const. When a pointer can point-to-a const object, we refer toThat const as a low-level const.-------------
