6.3.5 标签命名空间
By default, tags are added to the default Grails namespace and are used with the Here we have specified a where the prefix is the same as the value of the static This works from GSP, controllers or tag libraries
一般情况下,标签使用Grails的缺省命名空间,并且在GSP页面中使用g: prefix in GSP pages. However, you can specify a different namespace by adding a static property to your TagLib class:class SimpleTagLib {
static namespace = "my" def example = { attrs ->
…
}
}namespace of my and hence the tags in this tag lib must then be referenced from GSP pages like this:<my:example name="..." />namespace property. Namespaces are particularly useful for plugins.Tags within namespaces can be invoked as methods using the namespace as a prefix to the method call:out << my.example(name:"foo")g:前缀。但是你也可以通过在TagLib类中增加一个静态属性来指定另外一个命名空间:class SimpleTagLib {
static namespace = "my" def example = { attrs ->
…
}
}namespace指定为my,因此此标签库的标签在GSP页面中必须像如下所示那样引用:<my:example name="..." />namespace的值是一样的。命名空间对插件来说特别有用。带命名空间的标签也可以以方法的方式调用,需要将其命名空间作为前缀赋给方法调用:out << my.example(name:"foo")
