jquery - Get Details Entity By Id in ASP.Net MVC -

I am having a problem, I do not know how to display product information by entering product information into textbox , Then I press the tab button or move the mouse to the text box, which will automatically show detailed information on the product below.

Having HTML in the webform

  & Lt; Input type = 'text' Id = 'mytxt' / & gt; & Lt; Div id = 'description' & gt; & Lt; / Div & gt;  

You will do this:

  $ ('# mytxt'). Change (function () {$ .post ('& lt;%: Url Action ("Details")% & gt;', {ID: $ (this) .val ()}, function (result) {$ (' The action in the MVC will look like this:  
  public action statement details (string id ) {// Receive content in any way ... Return content (content);}
