A classic example is embedding Javascript or CSS code in a template. The problem arises as those languages use the { and } characters which are also the default delimiters for Smarty. 有時，忽略Smarty對某些語句段的解析很有必要。一種典型的情況是嵌入到模板中的javascript或Css代碼。原因在于這些語言使用與Smarty默認定界符‘｛’和‘｝’一樣的符號。 <table width="80%" border="0" cellpadding="2" cellspacing="2" class="note"><caption> 提示 </caption> <tr><td>Note<br/> A good practice for avoiding escapement altogether is by separating your Javascript/CSS into their own files and use standard HTML methods to access them. This will also take advantage of browser script caching. When you need to embed Smarty variables/functions into your Javascript/<br/> CSS, then the following applies.<br/> 一個避免出現這種情況的好習慣是把你的javascript/css代碼分離出來保存成一個獨立文件，再用html方法鏈接到模版中。這樣做也有利于瀏覽器緩存腳本。如果你想把Smarty變量、方法嵌入到javascript/css，請看下面的運用。</td> </tr></table> In Smarty templates, the { and } braces will be ignored so long as they are surrounded by white space. This behavior can be disabled by setting the Smarty class variable $auto_literal to false. 在Smarty模版，如果‘｛’和‘｝’大括號里包含有空格那么整個{}內容會被忽略，你可以設置Smarty類變量$auto_literal=false來取消這種規則。 **Example 3.8. Using the auto-literal feature** **Example 3.8. 使用auto-literal（自動原義）特性** <table border="0" bgcolor="#E0E0E0" width="100%"><tr><td> <p><script><br/> // the following braces are ignored by Smarty 以下大括號的內容會被Smarty忽略<br/> // since they are surrounded by whitespace 因為它們里面有空格<br/> function foobar {<br/> alert('foobar!');<br/> }<br/> // this one will need literal escapement 下面的內容會保持原義輸出<br/> {literal}<br/> function bazzy {alert('foobar!');}<br/> {/literal}<br/> </script></p> </td></tr></table> {literal}..{/literal} blocks are used for escaping blocks of template logic. You can also escape the braces individually with {ldelim},{rdelim} tags or {$smarty.ldelim},{$smarty.rdelim} variables. Smarty's default delimiters { and } cleanly represent presentational content. However if another set of delimiters suit your needs better, you can change them with Smarty's $left_delimiter and $right_delimiter values. [{literal}](#)...{/literal}塊被用來忽略模版語法的解析，你也可以用[{ldelim}](#)、[{rdelim}](#)標簽或[{$smarty.ldelim}](#)、[{$smarty.rdelim}](#)變量來忽略個別大括號（譯注：后面兩種方法主要用來在模版中輸出左右大括號）。 Smarty默認定界符‘｛’和‘｝’簡潔地描述具體的內容，然而如果你有更好的定界符設置，也可以用Smarty的[$left_delimiter](#)和[$right_delimiter](#)設置相應的值。 <table width="80%" border="0" cellpadding="2" cellspacing="2" class="note"><caption> 提示 </caption> <tr><td><p>Note:Changing delimiters affects ALL template syntax and escapement.
