jsp - Custom JSTL tags with body -
We are going to use JSTL and custom JSTL tags for some type of template engine in our JSP / Spring-project Are there.
Is there a way to create such a tag that looks like this:
& lt; Div id = "site" & gt; & Lt; Div id = "header" & gt; Some titles & lt; / Div & gt; & Lt; Div id = "navigation" & gt; Some dynamic content here & lt; / Div & gt; & Lt; Div id = "content" & gt; $ {Content} & lt; / Div & gt; & Lt; Div id = "footer" & gt; & Lt; / Div & gt; & Lt; / Div & gt; And use it like this:
& lt; Mytags: template> & Lt; H1 & gt; Title & lt; / H1> & Lt; P & gt; my content! & Lt; / P & gt; & Lt; / Mytags: Templates & gt; i.e. Use body-ingredients inside custom JSTL-tags ...
This works:
& lt; Mytags: Template Content = "Some Content ... No HTML" /> But not very useful in our case.
The answer to the same McDowell is, but with more flexibility, declare a feature that is a piece is.
For example, //foo.tag tag file
& lt;% @ attribute name = "greeting" fragment = "true"%> & Lt;% @ attribute name = "body" fragment = "true"%> & Lt; H1 & gt; & Lt; Jsp: invitation piece = "greeting" gt gt; & Lt; / H1> & Lt; P & gt; Body: & lt; Em> & Lt; Jsp: iwak fragment = "body" /> gt; & Lt; / Em> & Lt; / P & gt; jsp file
& lt; X: foo & gt; & Lt; Jsp: attribute name = "greeting" & gt; & Lt; B & gt; A fancy & lt; / B & gt; Hello & lt; / Jsp: attribute & gt; & Lt; Jsp: attribute name = "body" & gt; & Lt; Pre & gt; More fancy body & lt; / Pre & gt; & Lt; / Jsp: attribute & gt; & Lt; / X: foo & gt; This will produce this markup:
& lt; H1 & gt; & Lt; B & gt; A fancy & lt; / B & gt; Hello & lt; / H1> & Lt; P & gt; Body: & lt; Em> & Lt; Pre & gt; More fancy body & lt; / Pre & gt; & Lt; / Em> & Lt; / P & gt; & Lt; / Body & gt; The main advantage is to be able to do two pieces instead of just one tag.
