Selectors in Jquery:

Jquery provides some selector to make easy developer's works:

Below are those selectors:

1. #(ID selector) is used when need to select any control with Id
         e.g  <div id="dvemplist"></div>

               $("#dvemplist").html('your string');

2. element selector is used to select element
    e.g : $("p").hide(); can be select all P element of the page.
3. Class selector (.) is used to select all the controls with class name
        $(".your css name").show();
4. * to select all the  element
     $("*")

Note : Always try to use Id selector because it gives better performance than others


Except these  bellows are very useful:

$("*")	Selects all elements
$(this)	Selects the current HTML element
$("p.intro")	Selects all <p> elements with class="intro"
$("p:first")	Selects the first <p> element

$("ul li:first-child")	Selects the first <li> element of every <ul>

$(":button")	Selects all <button> elements and <input> elements of type="button"
$("tr:even")	Selects all even <tr> elements
