Although all server side components provide the option of including file like <jsp:include> etc, having a way to include files using clients side script can come handy if the pages are made of plain old HTML.<\/p>\n
We provide a code for explaining how Jquery can be used to include files.<\/p>\n
Main file:<\/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 \/\/loads include page using AJAX passing parameters and executes the function after completion\r\n $(\"#include\").load(\"incJquery.jsp\", {param1:25, param2:30}, function() {\r\n alert(\"Loading include file completed!\");\r\n });\r\n });\r\n <\/script>\r\n <\/head>\r\n <body>\r\n <div id=\"include\">Loading....<\/div>\r\n Welcome to Jquery <br\/>\r\n You see me in the main file!\r\n <\/body>\r\n<\/html><\/code><\/pre>\nInclude file:<\/p>\n
<%@ taglib uri=\"http:\/\/java.sun.com\/jstl\/core\" prefix=\"c\" %>\r\n<h2>Am from include file, thanks to Jquery!<\/h2>\r\nValue of Parameter1 is <c:out value=\"${param.param1}\"\/>\r\n<br\/>Value of Parameter1 is <c:out value=\"${param.param2}\"\/><p\/><\/code><\/pre>\nThe jquery load function basically is an AJAX call which loads the content and inserts it into the div with id=include.<\/p>\n
The load used uses the three parameter function. The first parameter being the URL, second is data (which is basically a key\/value pair object) and lastly a function. The data (key\/value) gets passed to the URL as parameters. The include file can access the parameters like any GET parameters received.<\/p>\n
Add both the files in a Java application server context. The files should be placed in same directory. Access the main file from browsers using a localhost url for going through the application server.<\/p>\n
See the contents loaded from include file and also the parameter contents received in the include file.<\/p>\n
\nDo not try to load pages from a different domain using the above script. It will not work and will provide a cross domain access error.<\/em><\/p>\n<\/blockquote>\n\u00a0<\/p>\n","protected":false},"excerpt":{"rendered":"
