Bản mẫu:Str mid/doc

Cách sử dụng

Characters in the source string are counted: the first is index 1, the last one is index length of string. The substring requested can be defined by these two indexes. Also, the substring can be defined by one index, and the substring length. The options are: {{str mid|<string>|<index of first character>|<length of substring>|<index of last character>}} It returns a part of the <string>, starting with character on position index, length <sublength>, last character returned is end index.

• {{str mid|Abcdefghijklmnopqrstuvwxyz|5|3}} → efg

If parameter 2 is omitted, start is from character 1:

• {{str mid|Abcdefghijklmnopqrstuvwxyz||5}} → Abcde

If parameter 3 is omitted, the whole rest of the string is returned:

• {{str mid|Abcdefghijklmnopqrstuvwxyz|15}} → opqrstuvwxyz

Tính từ cuối cùng

By entering a negative value, the index is counted from the end:

• {{str mid|Abcdefghijklmnopqrstuvwxyz|-7|4}} → tuvw
• {{str mid|Abcdefghijklmnopqrstuvwxyz|-7}} → tuvwxyz

Thay vào đó nếu độ dài chuỗi con, sử dụng chỉ số cho ký tự cuối cùng

By using parameter |4=n, a number, you do not ask for substring length, but the last character (as counted from the start of the input string):

• {{str mid|Abcdefghijklmnopqrstuvwxyz|5||7}} → efg

Khoảng cách được giữ lại

In the returned substring, spaces are kept:

• >{{str mid|I like this.|2|6}}< → >like<

But the input string is trimmed:

• >{{str mid| I like this. |2|6}}< → >like<

Thông báo lỗi

When the ranges (either param2 or the substring length) is out impossible in the string, an error is returned:

• {{str mid|Abcdefghijklmnopqrstuvwxyz|30}} →
• {{str mid|Abcdefghijklmnopqrstuvwxyz|0|45}} → efghijklmnopqrstuvwxyz

The error can be suppressed by using |ignore errors=true. A blank (empty string) will be returned:

• {{str mid|Abcdefghijklmnopqrstuvwxyz|0|45|ignore errors=true}} → efghijklmnopqrstuvwxyz

Thể loại lỗi

• |no category=true switches off category adding.
• |error category=[[Category:Your category name]] sets the category to be added when in case of an error.
