I have and accordion working on a normal html page, but when I try and add it to a Spring MVC page then I get the error: $(...).accordion is not a function.
Here is the header of my WEB-INF\views\index.jspfile:
<!DOCTYPE html>
<%# taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<html>
<head>
<title>Jeeni Software Ltd</title>

...
<!-- This is the 'accordion' div -->
<div id="accordion" style="height:800px;">
<h3>Title...</h3>
...
Here is the ready function:
$(document).ready(function() {
var object = $("#accordion");
alert("object: " + object.accordion);
$("#accordion").accordion({ collapsible: true, active: 'false', autoHeight: false });
$("#banner").fadeIn(1000);
alert("Done");
});
with this alert("object: " + object.accordion); show object: undefined and it bombs out on the next line.

Firebug shows no problem loading any of the jquery files. I can re-create the proper behavior outside of Spring mvc, so the problem must be something to do with Spring/Java?!? But I can not find out what. The only error Firebug reports is the $(...).accordion is not a function, but everything is setup just like on the jquery ui accordion example.
BTW, I've trawled the internet for the last 3 hours and found similar problems that were fixed by typos. This isn't a typo error. I can not find anything like this regarding jquery UI and Spring MVC.
Solved!
The problem was that I was importing some content via:
<jsp:include page="../includes/index_page_intro_txt.jsp" />
and this JSP file was re-importing jquery. Took this out and everything was fine.
Special thanks to #NimChimpsky for being a sounding board and keeping me going.
There's no way anyone could have solved this with the information above. So just let you all know how I solved it:
I started by removing everything from the file other than the library imports, the ready statement and the accordion div block. Then it worked. So I slowly added everything back until it stopped working and then investigated that cause.
Should have done that in the first place - duh!
<script type="text/javascript" src="<c:url value="js/jquery-ui-1.9.2.js">"></script>
is not correct in some way.
Can you get any jquery functions to work ?
Is it just the jquery-ui functions that are not working?
Did you customize the jquery-ui download and not include accordion ?
Do you get 404 in the browser debugger ?
Are you opening a popup which overwrites the jQuery object with something else ?
Also probably better to use a cdn hosted version of the jQuery lib files. The below gets the latest version and works with accordion.
<script src='http://ajax.googleapis.com/ajax/libs/jqueryui/1/jquery-ui.min.js' type='text/javascript'></script>

To working my static file (CSS, JS) I have to write absolute path like /AppName/templates/style/main.css. Is there any solution, that I could write relative path like style/main.css?
If your actual concern is the dynamicness of the webapp context (the "AppName" part), then just retrieve it dynamically by HttpServletRequest#getContextPath().
<head>
<link rel="stylesheet" href="${pageContext.request.contextPath}/templates/style/main.css" />
<script src="${pageContext.request.contextPath}/templates/js/main.js"></script>
<script>var base = "${pageContext.request.contextPath}";</script>
</head>
<body>
link
</body>
If you want to set a base path for all relative links so that you don't need to repeat ${pageContext.request.contextPath} in every relative link, use the <base> tag. Here's an example with help of JSTL functions.
<%# taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<%# taglib prefix="fn" uri="http://java.sun.com/jsp/jstl/functions" %>
...
<head>
<c:set var="url">${pageContext.request.requestURL}</c:set>
<base href="${fn:substring(url, 0, fn:length(url) - fn:length(pageContext.request.requestURI))}${pageContext.request.contextPath}/" />
<link rel="stylesheet" href="templates/style/main.css" />
<script src="templates/js/main.js"></script>
<script>var base = document.getElementsByTagName("base")[0].href;</script>
</head>
<body>
link
</body>
This way every relative link (i.e. not starting with / or a scheme) will become relative to the <base>.
This is by the way not specifically related to Tomcat in any way. It's just related to HTTP/HTML basics. You would have the same problem in every other webserver.
See also:
Browser can't access/find relative resources like CSS, images and links when calling a Servlet which forwards to a JSP
Is it recommended to use the <base> html tag?
Just use <c:url>-tag with an application context relative path.
When the value parameter starts with an /, then the tag will treat it as an application relative url, and will add the application-name to the url.
Example:
jsp:
<c:url value="/templates/style/main.css" var="mainCssUrl" />`
<link rel="stylesheet" href="${mainCssUrl}" />
...
<c:url value="/home" var="homeUrl" />`
home link
will become this html, with an domain relative url:
<link rel="stylesheet" href="/AppName/templates/style/main.css" />
...
home link
You start tomcat from some directory - which is the $cwd for tomcat. You can specify any path relative to this $cwd.
suppose you have
home
- tomcat
|_bin
- cssStore
|_file.css
And suppose you start tomcat from ~/tomcat, using the command "bin/startup.sh".
~/tomcat becomes the home directory ($cwd) for tomcat
You can access "../cssStore/file.css" from class files in your servlet now
Hope that helps, - M.S.
Instead using entire link we can make as below (solution concerns jsp files)
With JSTL we can make it like:
To link resource like css, js:
<link rel="stylesheet" href="${pageContext.request.contextPath}/style/sample.css" />
<script src="${pageContext.request.contextPath}/js/sample.js"></script>
To simply make a link:
<a id=".." class=".." href="${pageContext.request.contextPath}/jsp/sample.jsp">....</a>
It's worth to get familiar with tags
<%# taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>
There is also jsp method to do it like below, but better way like above:
<link rel="stylesheet" href="<%=request.getContextPath()%>/style/sample.css" />
<script type="text/javascript" src="<%=request.getContextPath()%>/js/sample.js"></script>
To simply make a link:
<a id=".." class=".." href="<%=request.getContextPath()%>/jsp/sample.jsp">....</a>
This could be done simpler:
<base href="${pageContext.request.contextPath}/"/>
All URL will be formed without unnecessary domain:port but with application context.
This is a derivative of #Ralph suggestion that I've been using. Add the c:url to the top of your JSP.
<%# taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<c:url value="/" var="root" />
Then just reference the root variable in your page:
<link rel="stylesheet" href="${root}templates/style/main.css">
I'm experiencing a peculiar issue and I'm having trouble diagnosing it.
I am using LessJs in an ASP.NET MVC web application and the less file is not being processed and I am seeing my variables in the "F12" debug tools -- and the style is not applied as expected as a bi-product.
The markup looks like this.
#Scripts.Render("~/bundles/modernizr")
<link href="~/Content/bootstrap.css" rel="stylesheet" />
<link href="~/Content/site.less" rel="stylesheet" />
<script src="~/Scripts/less-1.5.1.min.js" type="text/javascript"></script>
I am seeing the files correctly delivered to the browser (from Network tab)
There are NO errors in the console.
but when I inspect my element, I see this:
The styles from bootstrap.css are applied as expected.
Am I missing a step? I've used less with ASP.NET before, this one's got me stumped.
Thanks!
Solved. This issue was that the link tag that references the less files had an incorrect rel attribute. For less it should be stylesheet/less as opposed to just stylesheet, which is used for CSS.
<link href="~/Content/site.less" rel="stylesheet/less" type="text/css" />
The databox plugin works well in a static jQuery Mobile html page. The scripts defined in header are:
<link rel="stylesheet" href="http://code.jquery.com/mobile/latest/jquery.mobile.min.css" />
<link rel="stylesheet" type="text/css" href="http://dev.jtsage.com/cdn/datebox/latest/jquery.mobile.datebox.min.css" />
<script src="http://code.jquery.com/jquery-1.7.1.min.js"></script>
<script src="http://code.jquery.com/mobile/latest/jquery.mobile.min.js"></script>
<script type="text/javascript" src="http://dev.jtsage.com/cdn/datebox/latest/jquery.mobile.datebox.min.js"></script>
The line for the datebox input is:
<input name="mydate" id="mydate" type="date" data-role="datebox" data-options='{"mode": "flipbox","useFocus": true}'>
However, once I dynamically inject some other elements into the same page, like
$(document).bind("pagebeforechange", function route(e, data) {
...
$page.trigger('create');
...
As a result, I can see all elements are displayed well, including the datebox button. But clicks on the datebox button would not pop up anything.
I compare the two versions of html codes after enhancement. I found the dynamic one misses the following, which corresponds to the date dialog pop-up:
<div class="ui-datebox-container ui-overlay-shadow ui-corner-all ui-datebox-hidden pop ui-body-b"
...
Why did the dynamic way miss to generate the codes above? How can I correct?
I found a solution myself. It is to change
$page.trigger('create');
to
$page.page();
But I have no idea why and the fundamental difference of these two. Help please!
I am attempting to use jQuery Mobile in Spring Roo.
When I login to my application the application displays the source code for the last included javascript file.
Take a look at mjquery-scripts.tagx file below.
Notice that whatever is the last included file, the source code of that file, will be displayed in the browser.
The address will be something like https://testdomain.com:8080/scripts/jquerymobile/jquery.mobile-1.0.min.js
Now, when I type the url https://testdomain.com:8080/ I will be shown the proper page.
The problem seems to be that on login the redirection is to the path scripts/jquerymobile/jquery.mobile-1.0.min.js .
What could be causing this problem?
Even though I have indicated jquery.mobile this problem happens for jquery.min too.
The default load-scripts.tagx works just fine.
<jsp:root xmlns:c="http://java.sun.com/jsp/jstl/core" xmlns:jsp="http://java.sun.com/JSP/Page" xmlns:spring="http://www.springframework.org/tags" version="2.0">
<spring:url value="/scripts/jquery-1.7.min.js" var="jQuery_URL" />
<spring:url value="/scripts/jquerymobile/jquery.mobile-1.0.min.css" var="mobile_CSS" />
<spring:url value="/scripts/jquerymobile/jquery.mobile-1.0.min.js" var="mobile_js" />
<link rel="stylesheet" type="text/css" href="${mobile_CSS}"><!-- required for FF3 and Opera --></link>
<script type="text/javascript" src="${jQuery_URL}"><!-- required for FF3 and Opera --></script>
<script type="text/javascript" src="${mobile_js}"><!-- required for FF3 and Opera --></script>
This turned out to be a silly problem on my part.
I placed the jquery js files in the /src/main/webapp/scripts folder.
Moved them over to
/src/main/resources/web-resources
as in the following:
<jsp:root xmlns:c="http://java.sun.com/jsp/jstl/core" xmlns:jsp="http://java.sun.com/JSP/Page" xmlns:spring="http://www.springframework.org/tags" version="2.0">
<spring:url value="/resources/jquery-1.7-min/jquery-1.7.min.js" var="jQuery_URL" />
<spring:url value="/resources/jquerymobile/jquery.mobile-1.0.min.css" var="mobile_CSS" />
<spring:url value="/resources/jquerymobile/jquery.mobile-1.0.min.js" var="mobile_js" />
<link rel="stylesheet" type="text/css" href="${mobile_CSS}"><!-- required for FF3 and Opera --></link>
<script type="text/javascript" src="${jQuery_URL}"><!-- required for FF3 and Opera --></script>
<script type="text/javascript" src="${mobile_js}"><!-- required for FF3 and Opera --></script>
</jsp:root>
Now it works as expected.
Setting up a simple grails app with Dojo, i used the
grails install-plugin dojo
to setup the dojo js files. In my main.gsp i have this
<html>
<head>
<title><g:layoutTitle default="Grails" /></title>
<link rel="stylesheet" href="${resource(dir:'css',file:'main.css')}" />
<link rel="shortcut icon" href="${resource(dir:'images',file:'favicon.ico')}" type="image/x-icon" />
<g:layoutHead />
<g:javascript library="application"/>
<g:javascript library="dojo"/>
<dojo:header modules="['dojo.data.ItemFileReadStore','dijit.form.ComboBox']"/>
<g:javascript>
//dojo.addOnLoad(function(){alert("dojo loaded.");});
</g:javascript>
</head>
On my index.gsp page, i setup the following elements
<div>
<div jsId="search" dojoType="dojo.data.ItemFileReadStore"
url="<g:createLink controller="runner" action="findrunner"/>"></div>
<input dojoType="dojo.data.FilteringSelect"
id="chooser"
name="feed"
store="search"
searchAttr="url"
autocomplete="true"
pageSize="5"/>
</div>
Start the app but keep getting this error from firebug
GET http://localhost:8080/xxx/js/dojo/1.4.3/dojo/data/ItemFileReadStore.js

Any ideas?
Seems the 'dojo plugin' didn't seems to install all the required dojo files. I manually installed dojo 1.5 and extract the zip to /webapps/js/dojo/1.5.0 and enabled the version in my main.gsp like this
<script src="js/dojo/1.5.0/dojo/dojo.js"></script>
The new plugin version makes things a lot easier now. There is even a script to launch your custom builds in a breeze... and it's updated to dojo 1.6. Give it a try ;-)
