Asp.net implements spelling check using the Google Interface

Key words: spelling check SpellCheck English spelling check
When developing a foreign outsourcing project, the customer needs to input words in the text box and check the spelling before saving the project. If a word error is found, the user can be reminded to correct the problem, therefore, in combination with the reference of a variety of solutions, choose a free solution, Google an API interface, https://www.google.com/tbPRoxy/spell? Lang =, this interface provides spelling checks in multiple languages and returns similar words. Fortunately, an open-source package named googiespell was found online, therefore, after simple packaging, a spelling check widget is made, which is easy to use.
Implementation Principle
In. net page, before the submit button is submitted, send the text box content of the page to the Google interface in the form of Ajax and proxy class, the interface will return the spelling result, if there is no spelling Error, the browser will directly submit the operation. If there is an Error, a Spell Check Error dialog box will pop up, prompting the user to modify it. Click "yes" to return to the page for modification, click "No" to ignore spelling mistakes and submit them directly.
