[画像:Warning] This template is used on approximately5,300 pages and changes may be widely noticed. Test changes in the template's /sandbox or /testcases subpages, or in your own user subpage. Consider discussing changes on the talk page before implementing them.

This template uses Lua:

Module:String (sandbox)

{{strfind short |target|string}} outputs the position in target where string first appears (e.g. an output of "3" would mean beginning at the third character in target). If string is not found, it outputs zero (0). The word "short" in the title is a relic of the pre-Lua implementation and has no meaning for the current version. This template is a simple wrapper around {{#invoke:string|find}}, which may be used directly for more options.

Examples

Use {{#ifexpr}} to concisely determine if this outputs zero, which lets you check if one string contains another. For example, Does "A Funny Thing Happened on the Way to the Forum (film)" contain "on the"?

Markup	Renders as
{{#ifexpr: {{strfind short\| A Funny Thing Happened on the Way to the Forum (film)\|on the}} \| It does. \| It doesn't. }}	It does.
