Similar to above syntax and examples, following example would give you understanding on using different type of other useful selectors $(‘*’) 
This selector selects all elements in the document. $(“p>*”) This selector selects all elements that are children of a paragraph element. $(“#specialID”):This selector function gets the element with id=”specialID”. $(“.specialClass”) This selector gets all the elements that have the class of specialClass. $(“li:not(.myclass)”)Selects all elements matchbody <li> that do not have class=”my class”. $(“a#specialID.specialClass”)This selector matches links with an id of specialID and a class of specialClass. $(“p a.specialClass”) This selector matches links with a class of specialclass declared with in <p> elements. $(“ulli:first”) This selector gets only the first <li> elementof the <ul>. $(“container p”) Selects all elements matched by <p> that are descendants of an element that has an id of container. $(“li>ul”)Select all elements matched by <ul> that are children of an element matched by <li> $(“strong+em”)Selects all elements matched by <em> that immediately follow a sibling element matched by <strong> $(“p~ul”) Selects all elements matched by <ul> that follow a sibling element matched by <p>. $(“code, em, strong)Selects all elements matched by <code> or <em>or <strong>. $(“p strong ,.myclass”) Selects all elements matched by <strong> that are descendants of an element matched by <p> as well as all elements that have a class of myclass. $(“.empty”) Selects all elements that have no children. $(“p:empty”)Selects all elements matched by <p> that have no children. $(“div[p]”)Selects all elements matched by <div> that contain an element matched by <p> $(“p[.my class]”)Selects all elements matched by <p> that contain an element with aclass of myclass. $(“a[@rell]”)Selects all elements matched by<a> that have a rel attribute. $(“input[@name=myname]”)Selects all elements matched by <input> that have a name value exactly equal to myname. $(“input[@name^=myname]”)Selects all elements matched by <input> that have a name value beginning with myname. $(“a[@rel$=self]”)Selects all elements matched by <p> that have a class value ending with bar. $(“a[@href*=domain.com]”) Selects all elements matched by <a> that have an href value containing domain.com. $(“li:even”)Selects all elements matched by <li>that have an even index value. $(“tr:odd”)Selects all elements matched by <tr> that have an odd index value. $(“li:first”)Selects all the first<li> element. $(“li:last”)Selects all the last <li> element. $(“li:visible”)Selects all the element matched by<li> that are visible. $(“li:hidden”)Selects all elements matched by <li> that re hidden. $(“:radio”)Selects all radio buttons in the form. $(“:checked”)Selects all checked boxex in the form. $(“:input”)Selects only form elements (input, select, textarea, button). $(“:text”) Selects only text elements(input[type=text]). $(“li:eq(2)”) Selects the third <li> element. $(“li:eq(4)”) Selects the fifth <li> element $(“li:lt(2)”)Selects all elements matched by <li> element before the third one; in other words, the first two <li> elements. $(“p:lt(3)”)Selects all elements matched by <p> elements before the fourth one; in other words the first three <p> elements. $(“li:gt(1)”) Selects all elements matched by <li>after the second one. $(“p:gt(2)”)Selects all element matchen by <p> after the third one. $(“div/p”) Selects all elements matched by <p> that are children of an element matched by<div> $(“div//code”) Selects all elements matched by <code> that are descendants of an element matched by <div>. $(“//p//a”)Selects all elements matched by<a> that are descendants of an element matched by <p> $(“li:first-child)”) Selects all elements matched by <li> that are the first child of their parent. $(“li:last-child)”) Selects all elements matched by <li> that are the last child of their parent. $(“:parent”)Selects all elements that are the parent of another element ,including text. $(“li:contains (second)”) Selects all elements matched by <li> that contain the text second. You can use all the above selectors with any HTML/XML element in generic way .For example if selector $(“li:first”) works for <li> element then $ (“p:first”) would also work for <p> element.
