JSF模板:呈现的页面缺少DOCTYPE [英] JSF template: rendered page missing DOCTYPE
问题描述
TL; DR:我无法在我的JSF页面上显示DOCTYPE标头.
我刚刚继承了一个JSF 1.2项目，该项目在IE下存在一些显示问题.我是JSF的新手，但我认为问题出在以下事实中:呈现的页面(来自查看源")不包含正确的DOCTYPE.
I just inherited a JSF 1.2 project that's having some display issues under IE. I'm brand new to JSF, but I think the issues stem from the fact that the rendered pages (from "view source") do not contain a proper DOCTYPE.
这些页面由多个部分组成，并使用多层<ui:composition>组合在一起.典型的页面如下所示:
The pages are composed of multiple parts, brought together using several layers of <ui:composition>. A typical page will look like:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE composition PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<ui:composition xmlns="http://www.w3.org/1999/xhtml"
template="../layout/template.xhtml">
<ui:define name="body">
<!-- html content goes here... -->
</ui:define>
</ui:composition>
然后../layout/template.xhtml具有:
<ui:composition xmlns="http://www.w3.org/1999/xhtml"
template="./headertemplate.xhtml">
<ui:define name="menuSelection">
<ui:insert name="menuSelection"/>
</ui:define>
<ui:define name="body">
<ui:insert name="body"/>
</ui:define>
<ui:define name="footer">
<div class="footer">
<ui:include src="footer.xhtml"/>
</div>
</ui:define>
</ui:composition>
最后是headertemplate.xhtml:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd" >
<ui:composition xmlns="http://www.w3.org/1999/xhtml"
contentType="text/html">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
<body>
<ui:insert name="body" />
</body>
</html>
</ui:composition>
为了简洁起见，我省略了许多xmlns行；我希望你能明白.
I have left out many xmlns lines for brevity; I hope you get the idea.
如何使DOCTYPE显示在呈现的页面中?
推荐答案
从您的 master 模板(headertemplate.xhtml)中删除<ui:composition>.它不属于那里. <ui:composition>将剥离标签之外的所有其他内容.
Remove <ui:composition> from your master template, which is the headertemplate.xhtml. It doesn't belong there. The <ui:composition> will strip all other content outside the tag.
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd" >
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
</head>
<body>
<ui:insert name="body" />
</body>
</html>
请注意，模板定义文件(使用<ui:composition>的文件)中的doctype(和xml)声明是不必要.只需删除它们即可.
Note that the doctype (and xml) declaration is unnecessary in template definition files (the ones using <ui:composition>). Just remove them.
