This works because when we invoked the body we passed in the current value inside the iteration:. That value is then passed as the default variable it to the tag. However, if you have nested tags this can lead to conflicts, so you should instead name the variables that the body uses:.

Here we check if there is a var attribute and if there is use that as the name to pass into the body invocation on this line:. Notice how we use the var attribute to define the name of the variable j and then we are able to reference that variable within the body of the tag. By default, tags are added to the default Grails namespace and are used with the g: prefix in GSP pages. However, you can specify a different namespace by adding a static property to your TagLib class:.

Here we have specified a namespace of my and hence the tags in this tag lib must then be referenced from GSP pages like this:. Namespaces are particularly useful for plugins. Tags within namespaces can be invoked as methods using the namespace as a prefix to the method call:. In order to use JSP support you must ensure you have the grails-web-jsp dependency on your classpath by adding it to your build. Besides this you have to configure Grails to scan for the JSP tld files.

This is configured with the grails. It accepts a comma separated String value. For example you could scan for all available tld files by adding this to application. JSTL standard library is no longer added as a dependency by default.

In case you are using JSTL, you should also add these dependencies to build. A taglib can be used in a GSP as an ordinary tag or it might be used as a function in other taglibs or GSP expressions.

Internally Grails intercepts calls to taglib closures. The "out" that is available in a taglib is mapped to a java. Writer implementation that writes to a buffer that "captures" the output of the taglib call. If the tag is not included in the returnObjectForTags array, then its return value will be discarded.

Using "out" to write output in returnObjectForTags is not supported. Given this example cms. It might be worth doing so also because of performance optimization reasons. There is no need to wrap the tag return value in an output buffer in such cases. Table of contents 1 Introduction. Table of Contents 1 Introduction. Improve this doc. Although it is possible to have Groovy logic embedded in your GSP and doing this will be covered in this document, the practice is strongly discouraged.

Embedding data received from user input has the risk of making your application vulnerable to an Cross Site Scripting XSS attack. Within the scope of a GSP there are a number of pre-defined variables, including:. The section on Tag Libraries covers how to add your own custom tag libraries. Note that within the values of attributes you must use single quotes for Strings:.

Variables can be defined within a GSP using the set tag:. Form Fields In addition to easy construction of forms, GSP supports custom tags for dealing with different types of fields, including:. Multiple Submit Buttons The age old problem of dealing with multiple submit buttons is also handled elegantly with Grails using the actionSubmit tag.

Tags as method calls from GSPs Tags return their results as a String-like object a StreamCharBuffer which has all of the same methods as String instead of writing directly to the response when called as methods. Tags as method calls from Controllers and Tag Libraries You can also invoke tags from controllers and tag libraries. Template Basics Grails uses the convention of placing an underscore before the name of a view to identify it as a template.

The Template Namespace Since templates are used so frequently there is template namespace, called tmpl , available that makes using templates easier. This can be expressed with the tmpl namespace as follows:. Templates in Controllers and Tag Libraries You can also render templates from controllers using the render controller method.

Creating Layouts Grails leverages Sitemesh , a decorator engine, to support view layouts. Triggering Layouts There are a few ways to trigger a layout.
