Spell check settings

Remove Underline

By default, mis-spelled words are marked with squiggly line. You can also disable this behavior by enabling the removeUnderline API and now, the squiggly lines will never be rendered for mis-spelled words.

documentEditor.spellChecker.removeUnderline = false;

AllowSpellCheckAndSuggestion

By default, on performing spell check in Document Editor, both spelling and suggestions of the mis-spelled words will be retrieved, and this mis-spelled words can be corrected through context menu suggestions. You can modify this behavior using the allowSpellCheckAndSuggestion API, which will perform only spell check.

documentEditor.spellChecker.allowSpellCheckAndSuggestion = false;

LanguageID

Document Editor provides multi-language spell check support. You can add as many languages (dictionaries) in the server-side and to use that language for spell checking in Document Editor, it must be matched with languageID you pass in the Document Editor.

documentEditor.spellChecker.languageID = 1033; //LCID of "en-us";

• Refer to the Document Editor Web API service projects from GitHub link for configuring spell checker in server-side.

EnableOptimizedSpellCheck

Document editor provides option to spellcheck page by page when loading the documents. The default value of this property is false, so when opening the document spellcheck web API will be called for each word in the document. To optimize the frequency of spellcheck web API calls, you can enable this property.

The following code example illustrates how to enable optimized spell checking.

documentEditor.spellChecker.enableOptimizedSpellCheck = true;
