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 bug 672395.
The Window.find() method finds a string in a window.
Syntax
window.find(aString, aCaseSensitive, aBackwards, aWrapAround,
aWholeWord, aSearchInFrames, aShowDialog);
aString- The text string for which to search.
aCaseSensitiveBoolean. Iftrue, specifies a case-sensitive search.aBackwardsBoolean. Iftrue, specifies a backward search.aWrapAroundBoolean. Iftrue, specifies a wrap around search.aWholeWordUnimplementedBoolean. Iftrue, specifies a whole word search. This is not implemented; see bug 481513.aSearchInFramesBoolean. Iftrue, specifies a search in frames.
Returns
true if the string is found; otherwise, false.
Example
JavaScript
findString = function findText(text) {
alert("String \x22" + text + "\x22 found? " + window.find(text));
}
