<p>LiquidJS 是一个简单的、安全的、兼容 Shopify 的、纯 JavaScript 编写的模板引擎。这个项目的目的是为 JavaScript 社区提供一个 Liquid 模板引擎的实现。Liquid 最初用 Ruby 实现并用于 Github Pages, Jekyll 和 Shopify，参考 <a href="./differences.html">和 Shopify/liquid 的区别</a>。</p>
|
||
<p>LiquidJS 语法相对简单。LiquidJS 中有两种标记：</p>
|
||
<ul>
|
||
<li><strong>标签</strong>。标签由标签名和参数构成，由 <code>{%</code> 和 <code>%}</code> 包裹。</li>
|
||
<li><strong>输出</strong>。输出由一个值和一组可选的过滤器构成，由 <code>{{</code> 和 <code>}}</code> 包裹。</li>
|
||
</ul>
|
||
<blockquote class="note info"><strong class="note-title">在线示例</strong><p>在进一步了解细节之前，这里有一个在线示例：<a href="https://liquidjs.com/playground.html">https://liquidjs.com/playground.html</a>。</p>
|
||
</blockquote>
|
||
|
||
<h2 id="输出" class="article-heading"><a href="#输出" class="headerlink" title="输出"></a>输出<a class="article-anchor" href="#输出" aria-hidden="true"></a></h2><p><strong>输出</strong> 用于转换和输出变量到 HTML。下面的模板将会把 <code>username</code> 的值插入到 input 的 <code>value</code>：</p>
|
||
<pre class="line-numbers language-liquid" data-language="liquid"><code class="language-liquid"><span class="token tag"><span class="token tag"><span class="token punctuation"><</span>input</span> <span class="token attr-name">type</span><span class="token attr-value"><span class="token punctuation attr-equals">=</span><span class="token punctuation">"</span>text<span class="token punctuation">"</span></span> <span class="token attr-name">name</span><span class="token attr-value"><span class="token punctuation attr-equals">=</span><span class="token punctuation">"</span>user<span class="token punctuation">"</span></span> <span class="token attr-name">value</span><span class="token attr-value"><span class="token punctuation attr-equals">=</span><span class="token punctuation">"</span><span class="token liquid language-liquid"><span class="token delimiter punctuation">{{</span>username<span class="token delimiter punctuation">}}</span></span><span class="token punctuation">"</span></span><span class="token punctuation">></span></span><span aria-hidden="true" class="line-numbers-rows"><span></span></span></code></pre>
|
||
|
||
<p><em>输出</em> 里的值可以在输出之前经过若干个 <strong>过滤器</strong> 的转换。比如在变量后面追加一个字符串：</p>
|
||
<pre class="line-numbers language-liquid" data-language="liquid"><code class="language-liquid"><span class="token liquid language-liquid"><span class="token delimiter punctuation">{{</span> username <span class="token operator">|</span> <span class="token function filter">append</span><span class="token operator">:</span> <span class="token string">", welcome to LiquidJS!"</span> <span class="token delimiter punctuation">}}</span></span><span aria-hidden="true" class="line-numbers-rows"><span></span></span></code></pre>
|
||
|
||
<p>过滤器可以级联，用起来像管道一样：</p>
|
||
<pre class="line-numbers language-liquid" data-language="liquid"><code class="language-liquid"><span class="token liquid language-liquid"><span class="token delimiter punctuation">{{</span> username <span class="token operator">|</span> <span class="token function filter">append</span><span class="token operator">:</span> <span class="token string">", welcome to LiquidJS!"</span> <span class="token operator">|</span> <span class="token function filter">capitalize</span> <span class="token delimiter punctuation">}}</span></span><span aria-hidden="true" class="line-numbers-rows"><span></span></span></code></pre>
|
||
|
||
<p><a href="../filters/overview.html">这里</a> 是 LiquidJS 支持的完整的过滤器列表。</p>
|
||
<h2 id="标签" class="article-heading"><a href="#标签" class="headerlink" title="标签"></a>标签<a class="article-anchor" href="#标签" aria-hidden="true"></a></h2><p><strong>标签</strong> 用于控制模板渲染过程，操作模板变量，和其他模板交互等。例如 <code>assign</code> 可以用来定义一个模板中可以使用的变量：</p>
|
||
<pre class="line-numbers language-liquid" data-language="liquid"><code class="language-liquid"><span class="token liquid language-liquid"><span class="token delimiter punctuation">{%</span> <span class="token keyword">assign</span> foo <span class="token operator">=</span> <span class="token string">"FOO"</span> <span class="token delimiter punctuation">%}</span></span><span aria-hidden="true" class="line-numbers-rows"><span></span></span></code></pre>
|
||
|
||
<p>一般标签成对地出现，一个开始标签和一个对应的结束标签，比如：</p>
|
||
<pre class="line-numbers language-liquid" data-language="liquid"><code class="language-liquid"><span class="token liquid language-liquid"><span class="token delimiter punctuation">{%</span> <span class="token keyword">if</span> foo <span class="token operator">==</span> <span class="token string">"FOO"</span> <span class="token delimiter punctuation">%}</span></span>
|
||
Variable `foo` equals "FOO"
|
||
<span class="token liquid language-liquid"><span class="token delimiter punctuation">{%</span> <span class="token keyword">else</span> <span class="token delimiter punctuation">%}</span></span>
|
||
Variable `foo` not equals "FOO"
|
||
<span class="token liquid language-liquid"><span class="token delimiter punctuation">{%</span> <span class="token keyword">endif</span> <span class="token delimiter punctuation">%}</span></span><span aria-hidden="true" class="line-numbers-rows"><span></span><span></span><span></span><span></span><span></span></span></code></pre>
