Describe about Set Content .

•  To set content
  We will use the same three methods
• text() - Sets or returns the text content of selected elements
• html() - Sets or returns the content of selected elements (including HTML markup)
• val() - Sets or returns the value of form fields

The following example demonstrates how to set content with the jQuery text(), html(), and val() methods:

Example

$("#btn1").click(function(){
    $("#test1").text("Hello world!");
});
$("#btn2").click(function(){
    $("#test2").html("<b>Hello world!</b>");
});
$("#btn3").click(function(){
    $("#test3").val("Dolly Duck");
});
