Window: find() method

Non-standard: This feature is not standardized. We do not recommend using non-standard features in production, as they have limited browser support, and may change or be removed. However, they can be a suitable alternative in specific cases where no standard option exists.

Note: Support for Window.find() might change in future versions of Gecko. See Firefox bug 672395.

The Window.find() method finds a string in a window sequentially.

Syntax

find(string, caseSensitive, backwards, wrapAround, wholeWord, searchInFrames, showDialog)

Parameters

string: The text string for which to search.
caseSensitive: A boolean value. If true, specifies a case-sensitive search.
backwards: A boolean value. If true, specifies a backward search.
wrapAround: A boolean value. If true, specifies a wrap around search.
wholeWord: A boolean value. If true, specifies a whole word search.
searchInFrames: A boolean value. If true, specifies a search in frames.
showDialog: A boolean value. If true, a search dialog is shown.

Return value

true if the string is found; otherwise, false.

Examples

HTML

<p>Apples, Bananas, and Oranges.</p>
<button type="button" id="find-apples">Search for Apples</button>
<button type="button" id="find-bananas">Search for Bananas</button>
