eXist-db在.xq数据中包含html模板 [英] eXist-db include html template in .xq data

问题描述

我有一个index.html数据，其中通过以下方式包含了模板:

i have an index.html data where I included the template through:

<div xmlns="http://www.w3.org/1999/xhtml" data-template="templates:surround" data-template-with="templates/page.html" data-template-at="content">

在索引html站点上，我包括了一个关键字搜索表单，其思想是，当我单击搜索按钮时，它应该调用一个.xq文件来请求搜索结果:

At the index html site I included a keyword search form, and the idea is when I click on the search button it should call an .xq file to request the search results:

<form method="GET" action="ksearch.xq">

提交表单时，ksearch.xq页面会打开，即使我包含与上面相同的模板div:

When I submit the form, the ksearch.xq page opens, but even though I include the same template div as above:

<div xmlns="http://www.w3.org/1999/xhtml" data-template="templates:surround" data-template-with="templates/page.html" data-template-at="content">

ksearch.xq页面未应用模板.

The ksearch.xq page does not have the template applied.

当我调用.xq文件时，似乎没有应用模板，但是当我调用纯HTML文件时，则应用了模板.

It seems that when I call an .xq file the template is not applied, but when I call a plain HTML file, the template is applied.

所以问题是，如何在.xq文件的输出中也使用此模板?

So the question is how can I use this template also in output of an .xq file?

谢谢.

推荐答案

eXist-db的模板框架默认情况下对具有.html文件扩展名的文件(而不是.xq文件)的请求起作用.如您所见，模板框架将非.html文件中的结果通过不变的形式传递. (如果打开应用程序集合中的controller.xql文件，您将看到.html文件的特殊处理.)因此，让表单将搜索参数提交给使用该文件的.html文件而不是ksearch.xq.模板框架的约定以调用XQuery代码，例如

eXist-db's templating framework, by default, operates on requests for files with the .html file extension, not for .xq files. As you have found, the templating framework passes results from non-.html files through unchanged. (You will see the special handling for .html files if you open the controller.xql file in the app's collection.) Thus, instead of ksearch.xq, have your form submit the search parameters to an .html file that uses the templating framework's conventions to call XQuery code, e.g.,

<div xmlns="http://www.w3.org/1999/xhtml" data-template="templates:surround" data-template-with="templates/page.html" data-template-at="content">
    <div class="app:show-search-results"/>
</div>

此app:show-search-results类(由我组成)将指向app模块(在/db/apps/myapp/modules/app.xqm中)中的一个名为show-search-results()的函数，其常规参数如模板中的其他地方所用.功能.在这里放置搜索XQuery代码.

This app:show-search-results class (which I made-up) would point to a function in the app module (in /db/apps/myapp/modules/app.xqm) called show-search-results(), with the conventional arguments as used elsewhere in template functions. This is where you would put your search XQuery code.
