Get Content - text(), html(), and val()
Three simple, but useful, jQuery methods for DOM manipulation are:
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
text() and html() methods:
<script>
$(document).ready(function(){
$("#btn1").click(function(){
$("#test1").text("Hello world!");
});
$("#btn2").click(function(){
$("#test2").html("<b>Hello world!</b>");
});
$("#btn3").click(function(){
$("#test3").val("Dolly Duck");
});
});
</script>
Example(2) For getting the value of an input field with the jQuery val() method:
<script>
$(document).ready(function(){
$("#btn1").click(function(){
alert("Value: " + $("#test").val());
});
});
</script>
Get Attributes - attr()
The jQuery attr() method is used to get attribute values.
The following example demonstrates how to get the value of the href attribute in a link:
<script>
$(document).ready(function(){
$("#link").click(function(){
alert($("#linK_name").attr("href"));
});
});
</script>

$("#btn3").click(function(){

});
$("#show_value").click(function(){
alert("Value: " + $("#test").val());
});
$("#link").click(function(){
alert($("#linK_name").attr("href"));
