<script type="text/x-red" data-help-name="template">
<p>根据提供的模板设置属性。</p>
<h3>输入</h3>
<dl class="message-properties">
<dt>msg <span class="property-type">object</span></dt>
<dd>一个msg对象其中包含着用于填充模板的信息。</dd>
<dt class="optional">template <span class="property-type">string</span></dt>
<dd><code>msg.payload</code>填充的模板。如果未在编辑面板中配置则可以将设为msg的属性。</dd>
</dl>
<h3>Outputs</h3>
<dl class="message-properties">
<dt>msg <span class="property-type">object</span></dt>
<dd>由来自传入msg的属性来填充已配置的模板后输出的带有属性的msg。</dd>
</dl>
<h3>详细</h3>
<p>默认情况下使用<i><a href="http://mustache.github.io/mustache.5.html" target="_blank">mustache</a></i>格式。如有需要也可以切换其他格式。</p>
<p>例如:
<pre>Hello {{payload.name}}. Today is {{date}}</pre>
<p>receives a message containing:
<pre>{
date: "Monday",
payload: {
name: "Fred"
}
}</pre>
<p>输出的消息将会是:
<pre>Hello Fred. Today is Monday</pre>
<p>也可以使用流上下文或全局上下文中的属性:<code>{{flow.name}}</code>或者<code>{{global.name}}</code>,或者为了持久储存<code>store</code>,可以使用<code>{{flow[store].name}}</code><code>{{global[store].name}}</code>
<p><b>注意:</b>默认情况下,<i>mustache</i>将在其替换的值中转义任何非字母数字或HTML实体。为了防止这种情况请使用<code>{{{triple}}}</code>大括号。
