To check the profanity in the text for multilanguage, here we use WebPurify web service. This web service provide various callable methods including check, checkcount, replace, return etc. But here we are using the replace method (webpurify.live.replace) that will replace the profane word with a symbol we provide in the request url. Here is the documentation for the same to avail the services provided by this web service.

For a particular language, we need to generate a request url by integration console that need to be send to its endpoint specifying a method and some arguments.

Request url would be like 

http://api1.webpurify.com/services/rest/?api_key=d20978a07f17f8edf5efffd815f40f85&method=webpurify.live.replace&replacesymbol=*&lang=de&format=json'

where 

for each registered user, there would be an api_key

method defines the method we need to call

replace symbol is the symbol with which we replace the profane word

lang defines the language for which the profanity is intended to be checked

format defines the response format

Here is an example that implements the functionality to replace the profane words with symbol “*” for german language.

Example

Index.html

<form class="comment-form" method="post">
		<table>
			 <tr>
				<td>
					<input type="text" id="comment">
				</td>
				<td>
					<input type="button" id="go" value="GO">
				</td>
			</tr>
		</table>
</form>

test.js

$(document).on('click', '#go', function(){
								
			var apiBaseURL = 'http://api1.webpurify.com/services/rest/?api_key=d20978a07f17f8edf5efffd815f40f85&method=webpurify.live.replace&replacesymbol=*&lang=de&format=json';

			var lang = 'de';
			
    		$.ajax({
    			
    			type: "GET",
    			headers: {'Access-Control-Allow-Origin': '*'},
    			url: apiBaseURL+'&lang=de&text='+$('#comment').val(),
    			sync:true,
    			crossDomain: true,
    			
    			dataType:"jsonp",
    			success: function(response){
	    			console.log("successful"+JSON.stringify(response));
	    			console.log(JSON.stringify(response.rsp.text));
	    			var replacedstring = JSON.stringify(response.rsp.text);
	    			$('#comment').val(replacedstring.replace(/\"/g, ""));     
	    			
    			}, 
    			error:function(e){
        			
    				alert("Error"+e);
    			}
    		});
});
