A helper template to display an error, generally to be used from inside other templates. Categorizes the page in Category:有模板错误的页面.

Usage

{{ error | <error text> | <additional category> }}

or

{{ error | text=<error text> | cate=<additional category> }}

First unnamed parameter or text

Error message to display. Will be wrapped in a span.

title

Hover text.

from or source

Short string denoting the source of the error. If this parameter is provided, the page will be categorized in a "有来自$source的错误的页面" category. Additionally, the span output tag will be extended to include a data-source attribute holding this parameter's value. This facilitates, for instance, easy access of errors from the same source via JavaScript or CSS.

Second, third, ..., n-th unnamed parameter and cate, cate2, ..., cate<n>

Additional categories to categorize the page in, can be continued ad infinitum. Set $cate to n or no to prevent categorization altogether.
