Introduction to jQuery ajax contenttype
The jQuery ajax contenttype is used to specifies that the type of data sending to the server. The jQuery ajax contenttype option is a built-in option that is passed to the ajax() function in the jQuery. The contenttype option is also called as MIME (multipurpose internet mail extension) type, it includes an HTTP header that specifies the information about what kind of data we are sending to the server. The ajax() function is used to perform an asynchronous HTTP request to the server and by using the contenttype option it describes to the server what data is sending and expecting to process it.
Syntax –
$.ajax( { contenttype : value } );Parameters –
contenttype- This is an optional option. It specifies the what type of data is sending to server while ajax() send the request to server. The default value is “application/x-www-form-urlencoded”. It is a Boolean or string data type. The possible string type values for the contenttype are “text/html”, “text/plain”, “application/jar”, “image/png”, “multipart/form-data”, “image/gif”, “audio/mp3”, “application/json” and all. The default Boolean type value is false. The false value tell jQuery that not to set any content type header.

Working of ajax contenttype option
The jQuery ajax contenttype option is passed to the ajax() function with the value to specify what type of data is sending to the server. Suppose we have to do the asynchronous HTTP Post request and submit the data to the server. The type of data sending is JSON type which needs to be specified to the server. So we can use the ajax() function with contenttype option as “$.ajax( ‘/jquery/submitData’, { type : “POST”, contenttype : “application/json”, data : { myData: “Sample data.” } });”, where the first parameter is the URL where the data will submit. So, the data of specified content type submit to the server.
