To select the elements by tag name use jQuery Element Selector Syntax : $(element) $('td') // Selects all td elements $('div a') // Select all anchor elements that are descendants of div element $('div, span, a') // Selects all div, span and anchor elements Alerts the total count of td elements on the page [script type="text/javascript"] $(document).ready(function () { alert($('td').length); }); [/script] Selects all the tr elements on the page and changes their background colour to red [script type="text/javascript"] $(document).ready(function () { $('tr').css('background-Color', 'red'); }); [/script] Alerts the HTML content of the table [script type="text/javascript"] $(document).ready(function () { alert($('table').html()); }); [/script] Alerts the HTML content of each table row [script type="text/javascript"] $(document).ready(function () { $('table tr').each(function () { alert($(this).html()); }); }); [/script] Select and changes the background colour of all the div, span and anchor elements [script type="text/javascript"] $(document).ready(function () { $('div, span, a').css('background-Color', 'yellow'); }); [/script] Select all anchor elements that are descendants of div element [html] [head] [title][/title] [script src="jquery-1.11.2.js"][/script] [script type="text/javascript"] $(document).ready(function () { $('div a').css('background-Color', 'yellow'); }); [/script] [/head] [body] [div] [a href="http://pragimtech.com"]PragimTech[/a] [/div] [br /] [a href="http://microsoft.com"]Microsoft[/a] [/body] [/html] Changes the background color of even rows to gray and odd rows to yellow in both the tables. [script type="text/javascript"] $(document).ready(function () { $('tr:even').css('background-Color', 'gray'); $('tr:odd').css('background-Color', 'yellow'); }); [/script] To change the background color of even rows to gray and odd rows to yellow just for one of the table, use #id selector along with element selector. [script type="text/javascript"] $(document).ready(function () { $('#table1 tr:even').css('background-Color', 'gray'); $('#table1 tr:odd').css('background-Color', 'yellow'); }); [/script]
