Window: find() method

Non-standard: This feature is non-standard and is not on a standards track. Do not use it on production sites facing the Web: it will not work for every user. There may also be large incompatibilities between implementations and the behavior may change in the future.

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

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

Syntax

js

find(aString, aCaseSensitive, aBackwards, aWrapAround, aWholeWord, aSearchInFrames, aShowDialog)

Parameters

aString

The text string for which to search.

aCaseSensitive

A boolean value. If true, specifies a case-sensitive search.

aBackwards

A boolean value. If true, specifies a backward search.

aWrapAround

A boolean value. If true, specifies a wrap around search.

aWholeWord Unimplemented

A boolean value. If true, specifies a whole word search. This is not implemented; see Firefox bug 481513.

aSearchInFrames

A boolean value. If true, specifies a search in frames.

Return value

true if the string is found; otherwise, false.

Examples

JavaScript

js

function findString(text) {
  document.querySelector("#output").textContent = `String found? ${window.find(
    text,
  )}`;
}
