Search results

Find and replace

The document editor component searches a portion of text in the document through a built-in interface called OptionsPane or rich APIs. When used in combination with selection performs various operations on the search results like replacing it with some other text, highlighting it, making it bolder, and more.

Options pane

This provides the options to search for a portion of text in the document. After search operation is completed, the search results will be displayed in a list and options to navigate between them. The current occurrence of matched text or all occurrences with another text can be replaced by switching to Replace tab. This pane is opened using the keyboard shortcut CTRL+F. You can also open it programmatically using the following sample code.

You can close the options pane by pressing Esc key.

The Search module of document editor exposes the following APIs:

API Name Type Description
findAll() Method Searches for specified text in the whole document and highlights it with yellow.
searchResults Property This is an instance of SearchResults.

Refer to the following code example.

documenteditor.search.findAll('Some text', 'None');

Search results

The SearchResults class provides information about the search results after a search operation is completed that can be identified using the searchResultsChange event. This will expose the following APIs:

API Name Type Description
length Property Returns the total number of results found on the search.
index Property Returns the index of selected search result. You can change the value for this property to move the selection.
replaceAll() Method Replaces all the occurrences with specified text.
clear() Method Clears the search result.

SearchResultsChange event

DocumentEditor exposes the searchResultsChange’event that will be triggered whenever search results are changed. Consider the following scenarios:

  • A search operation is completed with some results.
  • The results are replaced with some other text, since it will be cleared automatically.
  • The results are cleared explicitly.

Refer to the following code example.

documenteditor.searchResultsChange = function() {

};

Customize find and replace

Using the exposed APIs, you can customize the find and replace functionality in your application. Refer to the following sample code.
