This article explains how Jquery can be used to implement a check all checkbox. On checking this ‘check all’ checkbox, all other checkboxes present in the page will be checked and when unchecked all the checkboxes will be unchecked.<\/p>\n
The below HTML code provides such an example:<\/p>\n
<html>\r\n <head>\r\n <script type=\"text\/javascript\" src=\"static\/jquery-1.3.1.js\"><\/script>\r\n <script type=\"text\/javascript\">\r\n \/\/Gets called after the page is completely loaded\r\n $(document).ready( function() {\r\n \/\/Get the click event of id checkAll\r\n $('input#checkAll').click(function(){\r\n \/\/Get the state of checkAll button.\r\n \/\/We will use it later to assign it to all other checkboxes\r\n \/\/See this currently points to checkAll element\r\n var checkAllState = this.checked;\r\n \/\/Fetch all checkboxes\r\n $('input:checkbox').each(function() {\r\n \/\/this now points to each checkbox iterated\r\n this.checked = checkAllState;\r\n });\r\n });\r\n });\r\n <\/script>\r\n <\/head>\r\n <body>\r\n <div><h2>Check All Check Box<\/h2><\/div>\r\n <div><input type=\"checkbox\" id=\"checkAll\" name=\"checkAll\"\/> <b>(Un)Check All Color<\/b><\/div>\r\n <div><input type=\"checkbox\" name=\"yellow\"\/> Yellow<\/div>\r\n <div><input type=\"checkbox\" name=\"green\"\/> Green<\/div>\r\n <div><input type=\"checkbox\" name=\"red\"\/> Red<\/div>\r\n <div><input type=\"checkbox\" name=\"blue\"\/> Blue<\/div>\r\n <div><input type=\"checkbox\" name=\"pink\"\/> Pink<\/div>\r\n <\/body>\r\n<\/html><\/code><\/pre>\nIn the javascript section, comments are provided in line explaining the code.<\/p>\n
Save the above code as a HTML including the Jquery lib in correct path and see the above code in action.<\/p>\n","protected":false},"excerpt":{"rendered":"
