Bách khoa toàn thư mở Wikipedia
Tài liệu bản mẫu[xem] [sửa] [lịch sử] [làm mới]

This template selects a sub-string from the target string based on selected indices. The indices are 1-based. If the end index is omitted, it returns the rest of the string. One can also specify negative indices, in which case the substr is selected by counting from the end of the string.

Named parameters

[sửa mã nguồn]

{{Str sub new|s=abcd=fgh|i=3|j=7}}

cd=fg

Equivalent to:

{{#invoke:string|sub|s=abcd=fgh|i=3|j=7}}

cd=fg

Named parameters are required if the target string contains an equals sign, where unnamed or numbered parameters will not work as expected:

{{str sub new|abcd=fgh|3|7}}

{{str sub new|1=abcd=fgh|2=3|3=7}}

cd=fg
